Abstract:
Cola species constitute an important non-timber forest product. Besides the food value, Cola is rich in numerous phytochemicals, making it more important for its use in both African traditional medicine and potentials in industrial pharmacopoeia. Knowledge about genetic diversity is essential for conservation. In this paper, we reported genetic variability of Cola acuminata and C. nitida germplasm across the Cola - producing states (the rain forest and derived savannah zones) in Nigeria using Random Amplified Polymorphic DNA (RAPD) markers. Fifteen primers which gives an average of 6.5 bands per primer were selected for both species. C. acuminata exhibited a higher level of variation with 71.5% of the detected markers being polymorphic (223 polymorphic alleles), whereas C. nitida presented 58.3% variation with 182 polymorphicalleles. Inter-population differentiation was measured as Jaccard?s similarity coefficient. The mean similarity index amounted to 42.5% in C. acuminata and 46.7% in C. nitida respectively. Results reveal the genetic structure of both species and conservation strategies are suggested.

Abstract:
Cola acuminata (Pal. De Beauv.), one of the many forest tree species which are of socio-economic importance in Western and Central Africa, is still exploited in the wild by subsistence farmers because it has not been domesticated yet. As a contribution to its domestication, the present study aimed at determining germination requirements and desiccation tolerance of seeds. Three substrates (forest topsoil, river sand and mixture of forest top soil and river sand), two photoperiods (12 hours/day and continuous darkness) and dehydration were investigated for their effects on seeds germination percentage. To evaluate the seeds’ tolerance to desiccation, fresh seeds were dried at laboratory temperature for 16 days during which seeds moisture content, seeds germination percentage and electrical conductivity of seeds leachate were monitored at two-day intervals. Results showed that the mean germination percentage recorded on the mixture of forest top soil and river sand (97.2 ± 1.0%) was significantly higher than that recorded on forest topsoil (85.5 ± 4.0%), which was in turn higher than that obtained on river sand (70 ± 1.5%). The effect of photoperiod on germination percentage was not significant (p = 0.112). As response to seeds drying, the mean germination percentage slightly decreased as moisture got lost, then drastically dropped when moisture content was below 45.95 ± 4.2%. Seeds failed to germinate when their moisture content fell below 27.1 ± 2.1%. Electrical conductivity of seed leachate exhibited a highly significant negative correlation with both germination percentage (p ˂ 0.01, r = -0.926) and moisture content (p ˂ 0.01, r = -0.931). It is concluded that the best substrate for C. acuminata seeds’ germination is the mixture of forest top soil and river sand in a 1/1 (v/v) ratio. Cola acuminata seeds are desiccation-sensitive and their storage behavior is recalcitrant. This is a significant constraint for conservation that should be addressed in further researches.Keywords: Cola acuminate, seed germination, photoperiod, desiccation tolerance, moisture content, storage behavior.

Abstract:
The inhibitory properties of the ethanolic and methanolic leaf extracts of Vernoniaamygdalina and Colaacuminata on the fungal pathogens isolated from infected tomato fruits were investigated. The pathogens were Fusariummoniliformes and Rhizopusstolonifer. Various concentrations of the extracts ranging from 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100% were separately added to PDA media. The fungal pathogens were separately inoculated into the media and incubated for seven days. Antifungal effects of these extracts on the mycelia growth of the pathogens were significant at P<0.05 for all treatments at higher concentrations. At 10-50% concentration, ethanolic and methanolic extracts of Vernoniaamygdalina and Cola acuminata had no significant effect on the mycelia growth of Fusariummoniliformes and Rhizopusstolonifer after seven days observation period. At 60-100% concentrations, the two pathogens were completely inhibited by ethanolic extracts of Vernoniaamygdalina and Cola acuminata. Methanolic extracts of Vernoniaamygdalina and Cola acuminata inhibited completely Fusariummoniliformes and Rhizopusstolonifer at 80-100% concentrations. The in vitro inhibitory effects of these extracts at higher concentrations indicated that they can be used for the control of tomato fruit rot. It may be necessary to use them in prolonging the shelf-life of fresh tomato fruit and some other fruits.

Abstract:
<span style="font-family: Times New Roman; font-size: small;"> </span><p>Wood anatomy of five <em>Cola</em> species was investigated to identify and describe anatomical features in search of distinctive characters that could possibly be used in the resolution of their taxonomy. Transverse, tangential and radial longitudinal sections and macerated samples were prepared into microscopic slides. Characteristic similarity and disparity in the tissues arrangement as well as cell inclusions were noted for description and delimitation. All the five <em>Cola</em> species studied had essentially the same anatomical features, but the difficulty posed by the identification of <em>Cola acuminata </em>and <em>Cola nitida</em> when not in fruit could be resolved using anatomical features. <em>Cola acuminata</em> have extensive fibre and numerous crystals relative to <em>Cola nitida</em>,<em> </em>while<em> Cola hispida </em>and <em>Cola millenii</em> are the only species having monohydric crystals. <em>Cola gigantica </em>is the only species that have few xylem fibres while other species have extensive xylem fibre. These features have proved very functional and strongly of diagnostic value in the classification and delimitation of the studied <em>Cola </em>species.</p><span style="font-family: Times New Roman; font-size: small;"> </span>

A utilização de plantas medicinais com fins terapêuticos, para tratamento, cura e prevenção de doenças, é uma das mais antigas formas de prática medicinal da humanidade. É cada vez mais freqüente o uso de plantas medicinais, mas muitas vezes as supostas propriedades farmacológicas anunciadas não possuem a validade científica, por não terem sido investigadas, ou por não tido suas ações farmacológicas comprovadas em testes científicos pré-clínicos e clínicos. O medicamento Kraftol é uma associação de extratos fluidos de Cinhona calisaya (Quina amarela), Cola acuminata (noz de cola), Paullinia cupana (guaraná), Iodo, Ácido tânico, Formato de sódio, Glicerofosfato de cálcio, Iodeto de potássio. É um medicamento indicado para o tratamento de convalescenças e nos estados de desnutrição, nas amgdalites, faringites e adenopatias. O objetivo do presente trabalho foi avaliar a ação antiedematogênica e antiulcerativa do medicamento Kraftol e do flavonóide Ipriflavona (7-isopropoxi-isoflavona), em processos inflamatórios como edema e ulcera gástrica em ratos machos da linhagem Wistar; e avaliar a atividade antiulcerativa dos extratos presentes no medicamento Kraftol de forma isoladamente e associados sem os sintéticos. Realizou-se também um estudo de toxicologia oral aguda e subcrônica (doses repetidas) do medicamento Kraftol, tendo como base a resolução No 90, de 16 de março de 2004 da ANVISA. Para o teste nos processos inflamatórios induziu-se edema na pata em ratos com a injeção de 0,02 ml da substância capsaicina (12,5 mg-1) e ácido araquidônico (2 mg/pata) e receberam o tratamento por via oral. As lesões gástricas foram induzidas com administração oral de ácido acetil salicílico (150mg/Kg em 1,5 ml de 0,2N HCl). Para avaliação da toxicidade pré-clínica os animais foram tratados por via oral com doses de acordo com Guia para realização de estudos de toxicidade pré-clínica de fitoterápicos, conforme a resolução vingente. Foram realizadas também análises bioquímicas complementares (leucograma, colesterol total, triglicerídeos, glicose , fosfatase alcalina, TGP, TGO, creatinina, uréia, potássio,ácido úrico, Gama GT) e análise macroscópica e microscópica dos órgãos quando necessário.
The use of medicinal plants with therapeutics purposes for treatment, cure and prevention of diseases is one of most ancient medical practices of humanity. The use of medicinal plants is increasingly spreading, but many times the allegedly pharmacological properties have no scientific validity either because they have not been investigated or because their pharmacological actions have not been proved in pre-clinical and clinical scientific tests. The medicine Kraftol is an association of fluid extracts of Cinhona calisaya (yellow kina), Cola acuminata (cola nut), Paullinia cupana (guaraná), Iodine, tannic acid, sodium phormate, calcium glycerophosphate, potassium iodate. It is a medicine indicated for the treatment of recovery and malnutrition, amygdalitis, pharingitis and adenophaties. The objective of the present work was to evaluate the antiedematogenic and antiulcer action of the medicine Kraftol and of the flavonoid Ipriflavone (7-isopropoxi-isoflavone), in inflammatory processes such as edema and gastric ulcer in Wistar breed male mice; and evaluate the antiulcer activity of the extracts present in the medicine Kraftol, isolatedly and associated without the synthetics. It was also carried out a study on oral sharp and subchronic toxology (repeated doses) of the medicine Kraftol, based on the ANVISA resolution 90, March 16, 2004. For the test in the inflammatory processes, an edema was induced in mice legs by injecting 0,02 ml of the capsaicin substance (12,5 mg -1) and arachdonic acid (2 mg/leg) as well as oral treatment. The gastric wounds were induced by oral administration of acetylsalicylic acid (150mg/Kg em 1,5 ml de 0,2N Hcl). In order to evaluate the pre-clinical toxicity, the animals were treated with oral doses according to the Guide for the accomplishment of studies on phytotherapic pre-clinical toxicity, following the current resolution. Complementary biochemical analyses were also carried out (leucogram, total cholesterol, triglicerids, glucose, alkaline phosphatase, TGP, TGO, creatinin, urea, potassium, uric acid, Gama GT) and microscopic and macroscopic analyses of the organs were performed as well, when necessary.

Abstract:
Deux espèces participent à la constitution génétique des bananiers comestibles Musa acuminata COLLA et M balbisiana COLLA (2n = 22). La détermination cytophotométrique des teneurs en ADN nucléaire de 3 clones appartenant aux 2 espèces précédentes n'a pas mis en évidence de différence inter ou intra-spécifique. La masse d'ADN est de 2,7 pg par noyau 2C. Les associations chromosomiques en méiose sont bonnes entre les 2 espèces aux niveaux 2n, 3n et 4n. Actuellement, aucune différence significative ne peut être mise en évidence entre les 2 génomes. Des remaniements chromosomiques réduisent la fertilité. Ils peuvent résulter de l'hybridation entre individus appartenant à des zones de diversification différentes. Une corrélation significative existe entre le taux de tétrades sphériques et la fertilité pollinique, ce qui conduirait à donner une signification particulière à l'orientation des 2 mitoses homéotypiques de la diade. La stérilité femelle d'origine chromosomique Des clones parthénocarpiques est accrue par une stérilité génique résultant de déviations de la formation des sacs embryonnaires, de la suppression de la fécondation et de l'avortement précoce des graines (relations d'incompatibilité entre l'embryon et l'albumen) Les tétraploïdes seminifères obtenus par traitement de plantules à la colchicine ont montré un ralentissement de la croissance et une réduction du nombre de fleurs femelles et de la fertilité femelle. 3 quadrivalents potentiels sont formés par cellule en méiose. La fertilité mâle des 4n est bonne avec une distinction morphologique des gamétophytes nette t 2n. L'importance du rôle des clones séminifères dans le programme d'amélioration du bananier est discutée
Two species are involved in the genetic background of edible bananas Musa acuminata Colla and M. B albisiana Colla (2n = 22). Inter or intra-specific differences do not exist between nuclear DNA amounts of 3 clones of the 2 species, determined by Feulgen cytophotometry. Nuclear DNA content amounst to 2. 7 pq per 2C nucleus. Meiotic chromosome pairing is good between both species at 2n, 3n and 4n levels. In the present state of knowledge, no significant difference can be shown between the 2 genomes. Chromosome changes reduce fertility. They result from hybridization between individuals of different geographic areas. Rate of spherical tetrads and pollen fertility are significantly correlated, which could give a special meaning to the orientation of the 2 homeotypic mitosis of the dyad. Female fertility of chromosome origin is increased in edible clones by embryo-sac development or fertilization failure and by abnormal relationships between embryo and endosperm. The wild tetraploids induced by colchicine treatment of seedlings have a slower growth rate and reduced numbers of female flowers and a lower female fertility. A mean of 3 potential quadrivalents are formed in the PMC. Tetraploid male fertility is good with a possibility of morphological separation of haploid and diploid gametophytes. Wild bananas interest in breeding scheme is discussed

Resumo: Este trabalho estudou o processo de obtenção de banana nanica crocante através da secagem a altas temperaturas e curto período de tempo (HTST - High Temperature and Short Time). O processo consistiu de um pré-tratamento a 70°C durante 5 minutos, de uma etapa à alta temperatura (130°C, 1400C e 150°C) e curto tempo (9, 12 e 15 minutos) e de uma etapa à temperatura de 70°C até atividade de água em torno de 0,320. De modo a verificar a influência da etapa HTST no processo, montou-se um planejamento experimental fatorial 22 com 3 pontos centrais, cujas respostas do processo foram o grau de reidratação, o parâmetro k do modelo de Lewis (para a etapa HTST, 70°C e secagem completa) e a crocância, avaliada por medidas sensoriais e instrumentais de textura. O planejamento experimental resultou numa matriz com as condições de ensaios de 130°C-9min, 130°C-15min, 150°C-9min, 150°C-15min e três pontos centrais a 140°C-12min. Banana crocante foi obtida com as condições de 140°C-12min e 150°C-15min de etapa HTST, com atividade de água de 0,345 e 0,363, respectivamente. Os resultados mostram que o melhor grau de reidratação ocorreu para os tempos de 10 e 5 minutos e que existe uma significativa relação entre a crocância e a temperatura da fase HTST. Não foi possível encontrar um ajuste adequado ao parâmetro k do modelo de Lewis para a etapa HTST e a 70°C, porque as umidades iniciais eram diferentes e promoveram grande diferença nos valores desse parâmetro. Adicionalmente, caracterizou-se a crocância de frutas comerciais liofilizadas e determinou-se a aw. Os resultados obtidos para a banana comercial liofilizada foram comparados com os da banana desidratada obtida neste estudo. As medidas instrumentais e sensoriais mostraram que ambas foram consideradas crocantes
Abstract: We present here a study about producing crispy banana using a HTST (High Temperature Short Time) process. The process involves pretreatment of the fruit during 5 minutes at 70°C, a dry HTST stage (130, 140 and 150°C and 9, 12 and 15 minutes) and, finally, a dry stage at 70°C until the water activity (aw) is near 0,300. In order to evaluate the HTST stage in the process, we used a factorial 22 design with 3 center points. The results produced by this analysis were the rehydratation degree, the model parameter of Lewis k (considering either the complete process, the HTST stage and the dry stage at 70°C). Also, crispness was analyzed according to sensorial and instrumental measurements. This process generated a matrix containing the results of several trial runs for the following settings: 130°C-9min, 130°C-15min, 150°C-9min, 150°C-15min and 3 center points at 140°C-12min. Crispy banana was obtained only with 140°C-12min and 150°C15min, where aw = 0,345 and aw = 0,363, respectively. The results show that the best rehydration degree occurs for 10 and 5 minutes. Also, there exists a relationship between the crispness (sensorial and instrumental) and the HTST stage. However, it was not possible to find a suitable value to the Lewis Model parameter k to HTST and 70°C dry stages. This is because the initial moisture of the fruits was not the same for all tests, which produced different values for k. In addition, we evaluated the crispness of commercial freeze-dried fruits and the water activity value. Finally, we compared measurements of the commercial banana with the dried banana obtained in this work. Both were considered crispy

Abstract:
A cultura da bananeira é de grande importância económica para a Ilha da Madeira. A procura de formas de agricultura mais sustentáveis, como é o caso da agricultura biológica, tem levado ao desenvolvimento de estratégias alternativas aos produtos fitofarmacêuticos que possam ser utilizadas pelos agricultores. O objectivo geral deste trabalho foi o contribuir para a agricultura da Madeira desenvolvendo uma estratégia de luta contra o nemátode-das-lesões-radiculares, Pratylenchus goodeyi, utilizando Solanum sisymbriifolium e S. nigrum como cultura armadilha ou como biofumigante. Os isolados de P. goodeyi foram obtidos a partir da cultura in vitro em discos de cenoura e de raízes de bananeira infectadas pelo nemátode. Apesar de P. goodeyi se ter reproduzido nas plantas de S. sisymbriifolium e de S. nigrum, os factores de reprodução foram muito baixos (0,001), podendo estas plantas serem consideradas como resistentes ou, pelo menos, hospedeiros fracos. Os efeitos da incorporação, de diferentes partes de S. sisymbriifolium e S. nigrum (raízes, raízes+parte aérea e parte aérea), no solo com plantas de bananeira, infectadas com P. goodeyi, foram avaliados em relação ao crescimento das plantas de bananeira e à reprodução do nemátode. Verificou-se que qualquer uma das espécies de Solanum influenciou o crescimento das plantas de bananeira, principalmente daquelas em que as raízes foram incorporadas no solo. A reprodução de P. goodeyi nas plantas de bananeira, apenas infectadas com o nemátode, foi superior à sua reprodução nas plantas em que ocorreu incorporação no solo. Relativamente aos efeitos dos extractos aquosos das plantas de Solanum na mortalidade de P. goodeyi concluiu-se que os extractos de S. sisymbriifolium foram os mais eficazes, principalmente na concentração de 250 mg/ml. De acordo com os resultados obtidos, conclui-se que as plantas S. sisymbriifolium e S. nigrum poderão ser utilizadas como biofumigante e como adubo verde, contribuindo para melhorar a qualidade e a quantidade das produções, eliminando os efeitos negativos, de produtos de origem química, sobre a saúde e o ambiente.

This study investigates effects of cryopreservation pretreatment by vitrification on banana (Giant Cavendish. Musa acuminata Colla). The physiological responses and observed section were analyzed by preculturing plantlets with high concentration of sucrose and cryoprotectant (LS and PVS2) treatment to investigate the effects and contribution of cryopreservation. The apices from in vitro-grown banana plantlets were precultured for short- and long-time on hormone-free MS medium containing different sucrose concentrations. The precultured apices were then treated with a loading solution (LS) for 0~60 minutes and then dehydrated with a plant vitrification solution (PVS2) for 0~3 hours, and following cryopreservation. Banana plantlet cultured on 0.3M sucrose medium long-time results in best survival rates of 37.5%, and treated without LN survival rates of 77.08%. Based on the physiological measurement，banana apices relative water content reduce, osmotic potential decrease, and both soluble sugar content and soluble protein content increase. These results indicated that banana plantlet culturing with high concentration of sucrose result in dehydration of banana shoot tips and accumulation of soluble sugar which renders high osmotic potential and increased freeze-tolerance for cryopreservation. It suggsets that precultrue in high concentration of sucrose is helpful for increasing survival rates after cryopreservation. Thus preculture with high concentration sucrose and the duration for pretreatment with cryoprotectant were achieved through investigating two key steps of the vitrification protocol.
