Abstract:

Ixoras (Ixora L.) growing in calcareous sandy soils are highly susceptible to a reddish leaf spot disorder. Symptoms appear on the oldest leaves of a shoot and consist of irregular diffuse brownish-red blotches on slightly chlorotic leaves. Symptoms of K deficiency, P deficiency, and both K and P deficiency were induced in container-grown Ixora `Nora Grant' by withholding the appropriate element from the fertilization regime. Potassium-deficient ixoras showed sharply delimited necrotic spotting on the oldest leaves, were stunted in overall size, and retained fewer leaves per shoot than control plants. Phosphorus-deficient plants showed no spotting, but had uniformly brownish-red older leaves and olive-green younger foliage. Plants deficient in both elements displayed symptoms similar to those observed on landscape plants. Symptomatic experimental and landscape ixoras all had low foliar concentrations of both K and P.

Abstract:

`Petite Yellow' dwarf ixoras (Ixora spp.) were grown in an alkaline substrate (3 limestone gravel: 2 coir dust) or a poorly aerated composted seaweed substrate to induce iron (Fe) chlorosis. Chlorotic plants were fertilized every 2 months with soil applications of 0.1 g (0.0035 oz) Fe per 2.4-L (0.63-gal) pot using ferrous sulfate, ferric diethylenetriaminepentaacetic acid (FeDTPA), ferric ethylenediaminedi-o-hydroxyphenylacetic acid (FeEDDHA), Hampshire Iron (FeHEDTA plus FeEDTA), ferric citrate, iron glucoheptonate, or DisperSul Iron (sulfur plus ferrous sulfate). Additional chlorotic ixoras growing in a substrate of 3 sedge peat: 2 cypress sawdust: 1 sand were treated every 2 months with foliar sprays of Fe at 0.8 g·L-1 (0.11 oz/gal) from ferrous sulfate, FeDTPA, FeEDDHA, ferric citrate, or iron glucoheptonate. Only chelated Fe sources significantly improved ixora chlorosis when applied to the soil, regardless of whether the chlorosis was induced by an alkaline substrate or a poorly aerated one. As a foliar spray, only FeDTPA was effective in improving chlorosis in dwarf ixora. Leaf Fe content either showed no relationship to plant color or was negatively correlated with plant chlorosis ratings.

Abstract:

Ixora and Psychotria are two distinct genera within the Rubiaceae family found at the Bogor Botanic Gardens. Despite taxonomic differences at the genus and subfamily levels, these plants share certain characteristics that necessitate identifying similarities. This study aims to identify resemblances between Ixora and Psychotria by examining their leaf architecture and evaluating significant morphological characteristics across recognized variables. The data analysis objective is to identify commonalities in leaf architecture and key distinguishing characteristics. Species under investigation include Ixora javanica (Blume) DC., Ixora paludosa (Blume) Kurz, Ixora coccinea L., Ixora chinensis Lam., Psychotria angulata Korth., and P. viridiflora Reinw. ex Blume. Thirteen characters were used to identify shared traits and influential features. Research findings showed both Ixora and Psychotria exhibit various characteristics. Cluster analysis indicated strong correlation among subjects under investigation, primarily due to shared characteristics. Distinguishing features significantly contributing to differentiation are leaf abaxial surface color and leaf base morphology. It can be concluded that abaxial leaf surface color holds potential as a distinguishing characteristic for Ixora, while leaf base exhibits distinguishing features for Psychotria.

Abstract:

In Indonesia, the soka plant (Ixora sp.) is an ornamental plant that is quite popular among ornamental plant hobbyists. Besides being unique, the shapes and types also vary. The purpose of this study was to identify the type of flower Ixora sp. located in Ngembal Rejo Village. This research method is descriptive qualitative by observing morphology. The results showed that there were 3 types of Ixora sp flowers. in Ngembalrejo Village, consisting of Ixora javanica, Ixora chinensis) and Ixora coccinia. So, the morphological differences in the soka plant only lie in the color of the flowers. Meanwhile, for the structure of leaves, stems and roots, there is dont difference because they are still in the same family and one genus.

Abstract:

The objective of this experiment was to optimize the post-harvest handling techniques for four Ixora genotypes grown for loose flower purpose. The experiment was laid out in Factorial Completely Randomised Design (FCRD) with four genotypes namely viz., Red (Ixora casei-G1), Pink (I. chinensis-G2), Orange (I. coccinea-G3) and Yellow (I. chinensis-G4) and six post-harvest treatments replicated three times. Observations were made on the floral quality criteria as well as the physiological characters linked with flower post-harvest quality. The results revealed that among the genotypes, Red (I. casei-G1) proved superior with respect to quality parameters and physiological parameters followed by Pink (I. chinensis-G2). Among the post-harvest treatments, treating flower buds with 4% boric acid and storage under refrigeration @ 50C recorded superior results for all the quality parameters viz., freshness index, flower opening index, colour retention and shelf life and the physiological parameters viz., moisture content, relative water content and physiological loss in weight.

Abstract:

Ixora Linnaeus (1753: 110) is the third largest genus of the family Rubiaceae with more than 500 species distributed in tropical and subtropical regions of the world (Mouly et al. 2009). The genus Ixora is easily recognized by its articulate petioles, tetramerous flowers, bilobed stigma, uni-ovulate locules and seeds with a large adaxial hilar cavity (De Block 2008). In India, the genus is represented by 47 species (Barbhuiya et al. 2012; Murugan & Prabhu 2014; Karthigeyan & Arisdason 2015). Among of them, Ixora agasthyamalayana Sivadasan & Mohanan (1991: 313), I. beddomei Husain & Paul (1986: 87), I. gamblei Ramachandran & Nair (1988: 220), I. johnsonii Hooker (1897: 139), I. lawsonii Gamble (1920: 247), I. malabarica (Dennstedt 1818: 37) Mabberley (1977: 539), I. manantoddii Husain & Paul (1991: 16), I. mercaraica Husain & Paul (1986: 88), I. monticola Gamble (1920: 246) and I. sivarajiana Pradeep (1997: 315) are endemic to Western Ghats (Singh et al. 2015). During the verification of Ixora species from the Western Ghats of Tamil Nadu, the author found that the name Ixora monticola Gamble (1920: 246) is an later illegitimate homonym of I. monticola (Hiern 1870: 177) Kuntze (1891: 287). Therefore, a new name, Ixora ravikumarii Kottaim., is proposed here as a replacement name for I. monticola Gamble.

Abstract:

Background – The rain forest genus Ixora currently comprises 37 species in Continental Africa. Within the framework of a treatment of the genus for the Flore d’Afrique centrale, a new species is described from D.R. Congo, despite its being known from only two specimens.Methods – Standard methods of herbarium taxonomy are followed.Key results – Ixora kalehensis De Block, a new species from the Central Forest District in D.R. Congo, is described and illustrated. Ixora kalehensis remains under-collected and relatively poorly known but can nevertheless easily be distinguished from other Ixora species. The most distinctive character is the colour of the dried leaves: blackish on the upper surface and vivid brown on the lower surface. Other important characters are the small-sized, compact and sessile inflorescences and the large tree habit. The species is only known from two specimens collected in the 1950s and its preliminary IUCN status is Endangered (EN B2ab(iii)). The lack of more recent herbarium material highlights that the collecting effort in D.R. Congo remains substandard. It is hoped that the formal description of Ixora kalehensis will draw attention of international and local collectors and will result in more material and greater knowledge of the species. The description of this species brings the number of Ixora species to thirteen for central Africa (D.R. Congo, Rwanda and Burundi) and to twelve for D.R. Congo. An identification key to the species of D.R. Congo is provided.

Abstract:

A ixora (Ixora coccínea) é um arbusto muito utilizado na floricultura e se destaca pelo seu uso como bordaduras, cercas vivas entre outros. O substrato comercial, embora apresente qualidade indispensável para produção de mudas, torna o custo final bem mais elevado e uma forma de superar essa limitação é a utilização de substrato regional ou alternativo. Visto que o mercado de flores tem crescido no ramo paisagístico do agronegócio, o presente trabalho teve como objetivo avaliar a utilização da palha de arroz carbonizada como substrato para a produção de mudas de ixora via estaquia. Adotou-se delineamento inteiramente casualizado, com cinco tratamentos e quatro repetições referente a utilização de substrato a base de casca de arroz carbonizada (CAC). Para todos os tratamentos, realizou-se a formulação de substratos (S) nas seguintes proporções: S1- 100% de areia; S2- 20% de CAC + 80% de areia; S3- 40% de CAC + 60% de areia; S4- 60% de CAC + 40% de areia; S5- 80% de CAC + 20% de areia. Os dados foram submetidos à análise de variância pelo teste 'F', para diagnóstico de efeito significativo e os tratamentos comparados entre si pelo teste de Duncan a 5% de probabilidade. Os substratos de casca de arroz carbonizada apresentaram resultados satisfatórios na propagação vegetativa das estacas de ixora. Recomenda-se, para propagação das estacas de ixora, a utilização de 80% de casca de arroz carbonizada acrescida a 20% de areia, como substrato alternativo para produção de mudas de ixora.

Abstract:

Ixora duffii is an important traditional medicinal plant in Vietnam. In this study its antioxidant property was investigated by diphenylpicrylhydrazyl (DPPH) radical and Fe3+ reducing assay and cytotoxic activity was evaluated against HepG2 cell line by MTT assay. The results showed that the methanolic extract of Ixora duffii flowers had DPPH radical scavenging activities similar to that of leaves extract. At the concentration of 100 􀁐g/mL, the extracts of flowers and leaves scavenged about 80% DPPH radical. The DPPH scavenging activity of Ixora duffii was lower than that of vitamin C approximately 2 times. The activity of Fe3+ reducing of flowers was higher than that of leaves, with EC50 values of 162.03 and 218.87 􀁐g/mL, respectively. Results were compared with the standard butylated hydroxyanisole (BHA) that was lower than 4.78 times in flowers and 6.76 times in leaves. The methanolic extract of Ixora duffii displayed significantly dose dependent in reducing the growth of HepG2, with 56% growth inhibitory concentration in a dose of 500 􀁐g/mL. The qualitative analysis of phytochemical compounds showed the presence of alkaloids, flavonoids, anthraquinones, terpenoids, quinones, glycoside, coumarins and phenols in the leaves and flower extracts of Ixora duffii. Compounds of tanins and saponins were only present in flowers of Ixora duffii. Total phenolic content were found in flowers (762.37 mg GAE/g) that was higher than the one in leaves (360.85 mg GAE/g). Flower and leave extracts exhibited a similar total flavonoid content of 679.55 mg QE/g and 676.35 mg QE/g, respectively.

Two new Ixora species from Madagascar are described, Ixora lagenifructa and I. quadrilocularis. Ixora littoralis, previously positioned in the monospecific genus Thouarsiora, is newly named I. homolleae. These three species are characterized by 4-locular ovaries and fruits, 4-lobed stigmas, large fruits with thick walls and well-developed calyces. A fourth species, I. trimera, shows the same characters but its ovaries are 2-, 3- or 4-locular and its stigmas are 2-, 3- or 4-lobed. A dichotomous key, detailed descriptions and distribution maps are given for these four species, the only multilocular ones in Madagascar.

Abstract:

A mini-ixora (Ixora coccinea 'Compacta') é uma espécie muito apreciada para uso em paisagismo, especialmente em jardins tropicais. A propagação é feita por estaquia, no entanto, a porcentagem de enraizamento é bastante baixa. Sendo assim, objetivou-se com este trabalho avaliar substratos e ambientes para o enraizamento da mini-ixora. Foram utilizadas estacas apicais com comprimento de 10 cm, as quais foram cultivadas em dois tipos de substratos: areia e o produto comercial Plantmax®. Utilizaram-se também três ambientes de enraizamento: câmara úmida, estufa e enraizador tradicional (telado com 50% de sombreamento). O delineamento experimental utilizado foi o de parcelas subdivididas, sendo três ambientes nas parcelas e dois substratos nas subparcelas. Utilizaram-se 5 repetições e 10 estacas por parcela. Analisando-se todos os resultados 100 dias após a implantação do experimento, observou-se que a areia proporcionou maior porcentagem de enraizamento (68%) quando comparada ao Plantmax (48%). A câmara úmida também foi o ambiente que proporcionou melhores condições para a propagação da mini-ixora com maior porcentagem de enraizamento, 98%, em relação a estufa (66%) e ao enraizador tradicional (10%). A areia e a câmara úmida também favoreceram a formação de raízes de melhor qualidade. Concluiu-se que o melhor substrato para propagação da mini-ixora foi areia devendo as estacas serem dispostas em câmara úmida.

Abstract:

A mini-ixora é uma planta ornamental propagada comercialmente por meio de estaquia e apreciada para uso em paisagismo. O enraizamento das estacas, no entanto, ocorre em baixa porcentagem, resultando em baixa produção de mudas nos viveiros. Visando otimizar a propagação vegetativa desta espécie, avaliou-se o efeito de diferentes estimuladores de desenvolvimento radicular e substratos sobre o enraizamento de estacas da mini-ixora. As estacas semi lenhosas com 10 cm de comprimento foram cultivadas em estufa climatizada. O delineamento experimental utilizado foi em blocos casualizados em esquema fatorial 2 x 6, sendo dois substratos (S1: 100% de areia lavada e S2: 50% de bagaço de cana + 50% de vermiculita) e seis estimuladores de enraizamento (água - testemunha; extrato de tiririca; hormônio comercial; AIB 1000 mg/L; AIB a 2000 mg/L e AIB a 4000 mg/L). Utilizaram-se quatro repetições e dez estacas por parcela experimental. Após 120 dias, foram avaliados os seguintes parâmetros morfológicos: estacas enraizadas (%), mortalidade (%), comprimento do sistema radicular, qualidade do sistema radicular e número de brotos por estaca. A propagação vegetativa das estacas de mini-ixora utilizando como substrato a mistura de bagaço de cana-de-açúcar com vermiculita proporciona maior porcentagem de enraizamento, comprimento radicular e menor porcentagem de mortalidade das estacas. O cultivo das estacas de mini-ixora no substrato composto de bagaço de cana-de-açúcar e vermiculita dispensa o uso de estimuladores de enraizamento para a obtenção de estacas com melhor qualidade do sistema radicular.

Rooting of mini-ixora cuttings (Ixora coccinea l. var. compacta) under different substrates and stimulators of radicular development Abstract Mini-ixora is an ornamental plant commercially propagated by cuttings. It is a species appreciated for use in gardens. The rooting of the cuttings, however, occurs in a low percentage, which results in low production of plants. In order to optimize the vegetative propagation of this species was studied the effect of different stimulators and substrates on rooting of mini-ixora cuttings. Cuttings with 10 cm were grown under controlled conditions. The experimental design was randomized blocks in a factorial scheme 2 x 6; two substrates (S1: 100% washed sand and S2: 50% sugarcane bagasse + 50% vermiculite) and six rooting stimulators (water; tiririca extract; commercial hormone; IBA 1000 mg/L; IAB 2000 mg/L and IBA 4000 mg/L). We used four replications and ten cuttings per experimental plot. After 120 days, we evaluated the following morphological parameters: percentage of rooted cuttings, percentage of mortality, length of the root system, root system quality and number of shoots per cutting. The vegetative propagation of the mini-ixora cuttings using as substrate a mixture of sugarcane bagasse with vermiculite provided the highest percentage of rooting, root length and lower percentage of mortality of the cuttings. The cultivation of mini-ixora cuttings on the substrate composed of sugarcane bagasse and vermiculite does not require the use of rooting stimulators to obtain cuttings with good quality of the root system. Keywords: Cuttings. IBA. Seedling production. Vegetative propagation.

Abstract:

Diaporthe taiwanensis sp. nov. (Diaporthales, Sordariomycetes, Ascomycota) isolated on living leaves of Ixora chinensis from Taiwan, is characterized using both phenotypic and genetic characters. Phylogenetic reconstructions based on concatenated DNA sequence data of four nuclear genetic markers (ITS, tef1-α, β-tubulin and cal) show that the new taxon is separated from other representative species of Diaporthe with high statistical support. The new taxon differs from its phylogenetically related congeners mainly by having larger alpha conidia and producing beta conidia in culture and further by host and geographical distribution. Artificial inoculation on leaves confirmed the pathogenicity of the novel fungus to Ixora. The present study is the first report of Diaporthe species causing leaf spots and necrosis on Ixora chinensis in Taiwan.

Abstract:

Ixora polyantha Wt. (Rubiaceae) is a rare, endemic species of the Western Ghats with high potential ornamental value. The fruit setting in this taxon is found to be rather infrequent when compared with other wild species of Ixora may probably be the reason for its rarity. The paper discusses the various experiments and results carried out in clonal propagation of the species.

Abstract:

The ixora is ornamental plant widely used in landscaping. In order to maximize the propagation of cuts, we evaluated the concentrations of auxin (indolbutiric acid) and the presence of leaves on the rooting in cuts of Ixora coccinea L. The experiment was conducted in randomized block design, in factorial design 3x4, with three types of cuts (without leaf, with two or four leaves), four concentrations of indolbutiric acid (0, 1000, 2000 and 4000 mg L-1), with four replications and 10 cuts in each experimental unit. After 53 days of implantation the experiment, evaluated the survival(%), rooting(%), sprouting(%), formation of callus(%), number, length and biomass of roots formed. The interaction of the type of cuts with concentrations of auxin was not significant for any of the variables analyzed. The survival of cuttings was not influenced by the treatments. Cuts with two or four leaves presented rooting and length of roots above the cuttings without leaves. The application of auxin does not substitute the presence of leaf in cuts of ixora in vegetative propagation. The vegetative propagation by cut of ixora can be made without application of auxin, and the leaves must be maintained in the cuttings.

Abstract:

Various factors that affect culture establishment, shoot growth, proliferation, and rooting of Ixora were discussed in this article. A stem segment with a node from Ixora coccinea was best suited as an explant. Micropropogation of Ixora involves culturing shoot tips on Murashige and Skoog (MS) medium supplemented with different concentrations of cytokinin. The use of cytokinin alone had a low effect on the shoot morphogenesis of Ixora. The results showed that a lot of calli be induced in MS medium with 2,4-D (2.0 mg/l), increased shoots, and a little callus were induced in medium MS with BA (1.0 mg/l) and NAA (0.2 mg/l). It also indicated that axillary buds of Ixora treated with NAA and IBA, using any substrate as support, allowed reaching optimal morphology development, ensuring the survival and rooting of the plants in 100%. The use of NAA encourages the initiation of the root and the number and length of roots after 25 days of culture. The basal application of auxin to the cuttings of treated shoots improves rooting. By sequential reculturing and subculturing, 15-20 usable shoots (more than 1cm length) could be produced from the 2-node shoot segments after 12–15 weeks of culture. Microcuttings taken from In vitro proliferated shoots were rooted on a half-strength MS medium containing NAA, IBA, and IAA (0.1–0.5 mg/l). 90% of the plantlets can be established under the conditions when transferred to a specially made plastic tray containing coco-peat as a potting mix.

Abstract Root systems of ‘Grande Name’ banana (Musa spp. L., AAA Group), Ixora coccinea L., Dracaena marginata L., and ‘Carrizo’ citrange [Citrus sinensis L. (Osbeck) × Poncirus trifoliata L.(Raf.)] were exposed to temperatures of 28°, 34°, and 40°C for 6 hr daily for 90 days. Root zone temperature did not affect dry weight of shoots or roots of ixora or citrus, but the 40° treatment increased the shoot to root ratio, S:R. Banana shoot dry weight decreased linearly with increasing root zone temperature, but root dry weight was not affected. The 40° root temperature regime reduced root dry weight in dracaena but not shoot dry weight. Absolute concentrations of sugars and starch in shoots and roots of the 4 test plants did not differ with root temperature, but the ratio of sugars to starch in roots was reduced in ixora and increased in banana by the 40° treatment.

Abstract:

Short-term effects of root-zone temperatures (RZT) of 28, 33, 38, and 43C for 6 hours daily on container-grown Musa spp. (AAA) `Grande Naine' and Ixora chinensis L. `Maui' were determined under greenhouse and growth room conditions. Diurnal fluctuation of leaf carbon assimilation (LCA) was altered by treatments. In the growth room at 43C, the maximum LCA occurred about midday for banana, but not until afternoon in ixora. LCA was highest (0.53 mg CO2/m2 per sec) in banana with a 33C RZT under greenhouse conditions, while it was equally high (0.74 mg CO2/m2 per sec) at 33 and 38C in a growth room. In ixora, 33C induced the highest LCA (0.40 mg CO2/m2 per sec) in the greenhouse at 1200 hr, but there were no apparent differences in midday LCA between plants with RZT of 28, 33, and 38C in the growth room. Effects of RZT and environment on the daily fluctuations of gaseous exchange processes raise questions about using measurements at only one time during the day to separate treatment effects.

Abstract:

Tarenna is a genus of relatives of Ixora which is found in forests. Tarenna is different from Ixora which is known as an ornamental plant. The purpose of this study was to find the genus Tarenna in Madura natural habitat to preserved or conserved before this genus became extinct. Observations were made on morphological characters. The morphological characteristics observed included: stature, stems, leaves, inflorescences, flowers, fruits, and seeds. Ixora has a corolla of various flowers while Tarenna only has a white corolla but smells good. Recent exploration and collection of Tarenna in Madura Island indicated that two species are a new record for Java and Madura Island, namely T. costata and T. fragrans. Existence of T. costata in this area not only as a new record for Madura Island, but also as a new record for Java. Tarenna fragrans was firstly reported in Madura Island as a new distributional record for this area. An updated of identification key, several descriptions, and documentations, as well as a distributional map are provided.

Abstract:

Background A large number of secondary metabolites can be obtained from plants used for traditional medicine in two related genera (Ixora and Greenea) in the subfamily Ixoroideae (Rubiaceae), but there are only a few detailed studies on their bioactivities. Therefore, the main goals of this study were to determine the antibacterial activities of lipophilic extracts from plants of some Ixora and Greenea species native to Thailand, and to isolate some pure compounds from those extracts. Moreover, we compared the occurrence of compounds in different plant parts of samples from different habitats to better understand their variation. Methods A total of 56 lipophilic extracts were obtained from the leaves, stem bark, and root bark of eight Ixora and two Greenea species collected at various locations in Thailand. Isolated compounds were identified using nuclear magnetic resonance. Antimicrobial activities were evaluated against four Gram-positive and nine Gram-negative human pathogenic bacterial strains. Results Extracts from I. javanica, I. nigricans, I. brunonis, and G. montana, along with isolated scopoletin, exhibited antibacterial activities against Gram-positive methicillin-resistant Staphylococcus aureus ATCC 43300, with minimum inhibitory concentration values ranging from 64 to 256 µg/mL. The occurrence of scopoletin, isofraxidin, and geniposidic acid in lipophilic extracts showed some variation among different plant parts and species. Conclusions Lipophilic extracts of Ixora and Greenea species have the potential to be developed as anti-Gram-positive agents, in particular to counter infections of methicillin-resistant S. aureus strains. The chemical profiles showed differences between floristic regions but similarity within the same plant parts.

Abstract:

Background: Soil Transmitted Helminth is an intestinal nematode whose reagent for microscopic examination is one of them using 2% Eosin solution. 2% eosin gives a red background against yellowish eggs and sells feces with feces. Eosin besides its many needs is also a reagent which is expensive compared to natural ingredients. The high price of eosin reagent paved the way for using local raw materials as an alternative to eosin staining. One of the local raw materials that can be used is red asoka flower (Ixora coccinea). Red asoka flowers contain anthocyanins which give color to flowers and fruit. Anthocyanin can be used as a natural red dye.Objective: to determine the use of red juice Ixora coccinea in microscopic examination of Soil Transmitted Helminths.Method: this type of quasi-experimental research with a completely randomized design (CRD). The data was obtained by recording the results of the treatment of red asoka flower juice (Ixora coccinea) on worm egg preparations. To see a comparison of the drying time of the reagents on worm egg preparations using red asoka flower juice (Ixora coccinea) with eosin control, three replications were carried out. Data were analyzed by T test.Results: the morphology of the eggshell and egg contents of the Soil Transmitted Helminth worm (Ascaris lumbricoides, Trichuris trichiura, Hookworm) was clearly visible. The results of the t test obtained a p value of 0.000 which is smaller than 0.05.Conclusion: Asoka flower juice can be used as an alternative to examining Soil Transmitted Helminth worm eggs (Ascaris lumbricoidea, Trichuris trichiura, Hookworm). the difference in drying time between asoka and eosin was significant.

Abstract:

Experiments were conducted on 6-month-old chinese ixora (Ixora chinensis Lam.) from February 1999 to April 2000. Floral development was studied with scanning electron microscopy (SEM) to determine the flowering sequences. Morphological characters were used to clarify the stages of flowering processes. The time of organogenesis and flowering arrangement was established through field observations. Floral evocation occurred in early September, floral initiation occurred in the middle of September and floral differentiation began in late September. A distinctly convex apex with bracts around the shoulder indicated the beginning of reproductive development. Subsequently, primary inflorescence axes were observed and differentiated into secondary, tertiary, and quaternary inflorescence axes consecutively in about one and a half months. Once the terminal apex reached the inflorescence bud stage, it would flower without abortion, and this may be assessed as no return. The sepals, petals, stamens, and pistil were well developed thereafter and anthesis was achieved in January through March in the following year. The observation of floral differentiation sequences and investigation of floret arrangement made it certain that chinese ixora had cymose inflorescence (cyme), but not corymb. A quadratic equation was established to predict floret number from the differentiation level (a quantitative description of differentiation stage) of a developed inflorescence.

Abstract:

Plants from Ixora genus exhibit a variety of pharmacological activities including antioxidant, antibacterial, and antitumor activities. This plants may contain many interesting bioactive compounds, especially phenolics and terpenoids groups. Ixora cumingiana is one of the Ixora species whose pharmacological effect has not been explored comprehensively. This study aimed to evaluate the antibacterial and antioxidant activity of eight extracts from bark and leaf of I. cumingiana. The plant samples were successively extracted using n-hexane, dichloromethane, ethyl acetate and methanol. The antibacterial evaluation was carried out against Staphylococcus aureus and the antioxidant activity was evaluated using a radical scavenging assay against 1,1-diphenyl-2-picrylhydrazyl (DPPH). Initial activity screening was performed using thin layer chromatography-bioautography followed by the determination of minimum inhibitory concentration (MIC) and the determination of antioxidant activity index (AAI) using microdilution technique. The dichloromethane extract of the bark as well as the n-hexane and dichloromethane extract of the leaf of I. cumingiana exhibited moderate antibacterial effect with MIC value of 128, 128, and 256 µg/ml, respectively. The methanol extract from the bark displayed a strong antioxidant activity (AAI = 1.5±0.13) and possessed the highest total phenolic content (43±0.91 mg AGE/ g extract). These experimental results showed that I. cumingiana is potential to be developed as an antioxidant agent rather than as an antibacterial agent.

Abstract:

Areca palms [Dypsis lutescens (H. Wendl.) Beentje & J. Dransf.], spathiphyllums (Spathiphyllum Schott. `Figaro'), ixoras (Ixora L. `Nora Grant'), tomatoes (Lycopersicon esculentum Mill. `Floramerica'), marigolds (Tagetes erecta L. `Inca Gold'), bell peppers (Capsicum annuum L. `Better Bell'), and pentas [Pentas lanceolata (Forssk.) Deflers. `Cranberry'] were grown in a pine bark-based potting substrate and were fertilized weekly with 0, 8, 16, 32, or 64 mg (1.0 oz = 28,350 mg) of P per pot. Shoot, and to a much lesser extent, root dry weight, increased for all species as weekly P fertilization rate was increased from 0 to 8 mg/pot. As P fertilization was increased from 8 to 64 mg/pot, neither roots nor shoots of most species showed any additional growth in response to increased P. Root to shoot ratio decreased sharply as P fertilization rate was increased from 0 to 8 mg/pot, but remained relatively constant in response to further increases in P fertilization rate.
