Ginger (Zingiber spectabile) is cultivated worldwide as a floriculture and landscaping species. Studies on the biology floral morphology of this species are important for its improvement; however, they scarce. We investigated reproductive gingers grown in germplasm bank. Floral development was monitored during pre-anthesis anthesis periods. morphometry, pollen viability, stigmatic receptivity, ...

Cotton grown in the Mississippi Delta often flowers in temperatures that are suboptimal for the species. High-temperature stress leads to a decrease in the photosynthetic efficiency of the plant and hinders proper growth and development. If the efficiency is hindered for a significant period of time, then the plant must repartition resources to facilitate its survival rather than for reproducti...

The fate of sucrose (Suc) supplied via the phloem to developing oilseed rape (Brassica napus) seeds has been investigated by supplying [(14)C]Suc to pedicels of detached, developing siliques. The method gives high, sustained rates of lipid synthesis in developing embryos within the silique comparable with those on the intact plant. At very early developmental stages (3 d after anthesis), the li...

In angiosperms, the ovary wall resumes growth after pollination through a balanced combination of cell division and cell expansion. The quantitative pattern of these events remains poorly known in fleshy fruits such as tomato (Solanum spp.), in which dramatic growth of the pericarp occurs together with endoreduplication. Here, this pattern is reported at the level of each of the cell layers or ...

Despite substantial evidence on the essential roles of cell wall invertase (CWIN) in seed filling, it remains largely unknown how CWIN exerts its regulation early in seed development, a critical stage that sets yield potential. To fill this knowledge gap, we systematically examined the spatial and temporal expression patterns of a major CWIN gene, GhCWIN1, in cotton (Gossypium hirsutum) seeds f...

in order to evaluate the effect of nitrogen rates and green manure crops on dry matter mobilization and mobilization efficiency indices of wheat (triticum aestivum l.) a field experiment was conducted in agricultural faculty of shahid chamran university, ahvaz during growing season of 2010-2011. the experimental design was split-plot based on randomized complete block with three replications. m...

CURRENT SCIENCE, VOL. 104, NO. 4, 25 FEBRUARY 2013 426 is, thus, simultaneous with or occurs immediately before anthesis (Figure 1 c– f ). (ii) In some flowers opening initiates by the expansion of the apices of the tepals, the stimulus of which then spreads laterally (Figure 1 a and b). However, what is interesting to note is that the anthers are still in an undehisced state. It takes more tha...
