Abstract:
Analysis of the inflorescence structures of 188 species from French Guyana belonging to the Melastomataceae (Myrtales) confirms that the panicle (of flowers or cymes) is the inflorescence which, under the effect of a homogenization process, gives rise to the determinate raceme (a single raceme of flowers or of cymes, or more rarely, a double raceme), and later by truncation, the indeterminate raceme. The impoverishment of these flowering units can give rise to triads which correspond to uninodal racemes morphologically identical with dichasia (triflorous cymes), albeit of a different origin, since the cyme is considered as resulting from the enrichment of a flower and thus assimilated to the latter as a flowering unit. Extreme impoverishment of these uninodal racemes gives rise to a single flower. Melastomataceae have two peculiar features: successively developing pauciflorous groups and long proliferous shoots with short side shoots specifically for flowering. Within the framework of intrafamily classification, all these inflorescences, by virtue of their great diversity and the series of links between their structural variations, may constitute an essential basis for research on phylogenetic links between taxonomic groups.

Abstract:
Celastraceae are characterized by a cymose pattern of inflorescence ramification. Under this basic pattern, many inflorescence forms have been described within the family, e.g., dichasium, monochasium, pleiochasium, botryoid, thyrsoid, fascicle. Thus, the question has arisen—how have these varieties evolved or transformed from one to another? Through morphogenetic observations using paraffin sections, scanning electron microscopy (SEM), and stereomicroscopy, we studied the architecture and developmental processes of the inflorescences of five species of Celastrus and Euonymus. We found in C. orbiculatus that the reduction of subtending leaves of the axillary dichasia on a developing flowering shoot made it become a terminal thyrsoid. A dichasium in the leaf axil as commonly seen in Euonymus is the most frequent type of inflorescence in Celastraceae. An analysis of character evolution suggested that a dichasium is the ancestral state for Celastraceae. Therefore, within Celeastaceae, an axillary dichasium may be the basic type or unit of inflorescences. Transitions from dichasium to thrysoid and other types of cymes, and even to solitary flowers might have occurred repeatedly in the family, probably a phenomenon of evolutionary convergence due to changing environmental conditions. The present study provided helpful information for understanding the evolution of the cymose type of inflorescence in flowering plants.

Abstract:
Selection emphasis on cyme size and flower color of Heliotropium arborescens L. has led to cultivars with diminished floral fragrance. As a preliminary inquiry into the fragrance chemistry of the species, we identified 41 volatile compounds emanating from the flowers of 'Marine' via isolation (Tenax trapping) and gas chromatography–mass spectrometry. The majority of the volatile compounds emanating from the flowers were terpenes (camphene, p-cymene, δ-3-carene, α-humulene, δ-1-limonene, linalool, (E)-β-ocimene, α-pinene, and β-thujone), benzenoids of which benzaldehyde was the most abundant, aldehydes (decanal, heptanal, nonanal and octanal), and hydrocarbons (decane, heneicosane, heptadecane, hexadecane, nonadecane, nonane, octadecane, tetradecane, tridecane and undecane) along with a cross-section of other compounds. Subsequent identification and quantification of critical ordorants will facilitate selecting new cultivars with quantitative and qualitative improvements in fragrance.

Abstract:
The inflorescence of tomato has been characterized as either a cyme or raceme. Cymose inflorescences are determinate, whereas racemose inflorescences are indeterminate. In this study, we addressed the discrepancy in inflorescence architecture by analyzing the morphology of a wild relative of tomato Solanum pimpinellifolium L. and four domesticated Solanum lycopersicum L. lines. Careful observation of developing inflorescences of both species showed a bifurcation of the meristem into a determinate floral and an indeterminate inflorescence meristem. Interestingly, higher fruit carpel number was associated with delayed floral development, which might give the impression of determinate growth in some of the lines. Nevertheless, our results demonstrated that tomato inflorescences are indeterminate in nature regardless of the line studied. Floral buds were formed concomitantly with the development of the inflorescence meristem and not on the flanks of the peduncle, a characteristic of racemose growth. Thus, tomato inflorescences should be classified as a cyme with the note that the inflorescence meristem does not terminate into a flower and, in fact, maintains indeterminacy. In addition, S. pimpinellifolium produced many more flowers in a highly regular manner when compared with the cultivated types. This demonstrated the usefulness of wild relatives of tomato as a tool to further understand flower and fruit development in this crop species.

Abstract:
Primulina cordistigma, a new species from Guangdong, China, is illustrated and described. This new species is similar to P. yangchunensis, from which it is distinguished by the leaf blades broadly ovate, 4–5 × 2–3.5 cm, base broadly cuneate to cordate, and margins entire or rarely undulate; the inflorescence a cyme 1–5-flowered; the bracts lanceolate, 3–4 × 0.5–1.0 mm; the corolla tube 0.9–1 cm long; staminodes 3; and the stigma cordate with elliptic lobes covered by shortly puberulent hairs. A conservation category of “Endangered” (EN) according to IUCN Red List Category and Criteria is proposed. Based on plenty of specimens with flowers and field works, the floral morphology of P. yangchunensis, which is the congener of P. cordistigma, is supplemented and emendated here.

Abstract:
A progressive increase in temperature from 14 to 30C resulted in linear increases in stem length and node number and decreases in stem diameter and stem strength. Higher temperatures also resulted in additional flower abortion, reduced time to flowering and fewer flowering stems per inflorescence. Reduction in the photosynthetic photon flux (PPF) from 695 to 315 μmole m-2s-1 had similar effects as increasing the temperature on vegetative parameters but had little effect on reproductive parameters. The rate of stem elongation was greatest at low PPF for all temperatures and at high temperature for all PPF treatments. Net photosynthesis rose between 14 and 22C and declined at 30C for all PPF treatments. Long photoperiods (12, 14 hr.) resulted in longer internodes, longer stems and more flowers per cyme than short photoperiods (8, 10 hr) but photoperiod had little effect on flowering time.

Full text
Abstract:
Clerodendrum inerme (L.) Gaertn. (Lamiaceae) is bisexual, self-compatible and has a vector-dependent mixed breeding system. They are dichogamous and herkogamous; the day 1 flowers are staminate while the day 2 and 3 flowers are pistillate. The plant blooms in the evening, possesses a white long corolla with a hairy interior to exclude other insects and strong fragrance are adaptations for pollination by the hawk-moth Macroglossum gyrans. The 2nd and 3rd day flowers are nectar-rich and attract hawk-moths during the dawn and dusk hours. The plant is also visited by bees and butterflies. The bees Xylocopa and Anthophora are primary nectar robbers which collect nectar without effecting pollination. In C. inerme, three forms of flowers can be distinguished based on the position of sex organs. The first form is characterized by elongated stamens and a style which occur in close proximity to each other just after anthesis facilitating contact between the stamens and stigma. The second form is characterized by the scattered position of stamens and style. In the third form, the stamens are fully extended while the style is curved away from them, either to the left or to the right; subsequently the stamens curl inward and the style elongates. Interestingly, the three flower forms can be found within a cyme also. These forms of flowers with strong protandry prevent autonomous selfing but not geitonogamy. The fruit is a capsule and breaks open to disperse nutlets. Birds such as Acridotheres tristis, Corvus splendens, Corvus macrorhynchos and Turdoides caudatus disperse nutlets during the early winter season. Seeds germinate in June and seedlings grow gradually to produce new plants.

Abstract:
Many pipeline industry managers and senior officials intuitively understand that location is important to most aspects related to pipelines throughout the life-cycle — from project concept, through construction and operations and finally to decommissioning. However, many organizations are not taking full advantage of location as being a vital component to support business decision-making across the entire range of activities undertaken by pipeline companies. A Geographic Information System (GIS) is a tool that takes advantage of geography. GIS is ideally suited for the storage, display, and output of geographic data, and moreover, the analysis and modeling of geographic data. While GIS has been around as a technology for over 30 years it is only in the last several years that it has started to be extensively used within the pipeline industry. Most managers have heard about GIS. Many organizations have already started to implement GIS and CAD-based solutions through individual projects and with a technical focus of automating work flows or business processes such as generating alignment sheets, regulatory compliance, integrity management, and land management to name a few. Given that many of these applications tend to be stand-alone or isolated developments, pipeline companies need to look at the complete spatial environment of all potential tools and applications, and support this with a vision of a common spatial data warehouse in a holistic sense. Any company that embraces a continuous gathering of spatial data throughout the pipeline life-cyle will have a significant knowledge base whose value will increase over time. A spatial data warehouse of truly integrated environmental, engineering and socioeconomic factors related to a pipeline during the entire lifecycle will have a total value that transcends the value of the individual factors. The Return on Investment (ROI) of a properly developed GIS framework and spatial data warehouse looking at all operational demands and support applications will certainly be many times over the original expenditure as measured in cost savings as well as better decision making. This paper will present insights and approaches into how to properly and effectively leverage the spatial data asset and in deploying GIS throughout the enterprise. These include addressing all of the elements that are key in implementing GIS — hardware, software, data, people and methods — as well as considering some of the ROI and value-based measures for GIS success.
