Both leafless and leafy inflorescences had similar fruit set rates (P > 0.05) because of sufficient (or excessive) carbon assimilation supply potential for fruit development. At this time, fruitlets at early stages with fruit length smaller than 1 cm are abscised. Flowering Patterns: Serially Expressed Flower Sex. & Simpson, D.R. phenology in early-maturing litchi is required in the future. Occasionally, blooms start with female flowers without male flowers as stated above, this is mostly observed on shoots accumulated less cool temperatures [7,13]. 1990 Endogenous growth substances in xylem and shoot tip diffusate of lychee in relation to flowering HortScience 25 314 315, Chu, Y.C., Lin, T.S.

Productive potential of litchi is impacted by photo-assimilate supply from the recurrent flushes on the bearing shoots and the environmental conditions during the reproductive growth. There are some seedling selections with promising fruit qualities in many countries. The edible portion of litchi is called aril, lies under the papillate, pinkish-red pericarp and completely surrounds the dark-brown, oily skinned seed. These results were consistent with an observation by Chang and Lin (2003) but lower than the results obtained for cultivars Tai So (Menzel and Simpson, 1992) and Haak Yip (Mustard et al., 1953), at 8% to 21% and 40%, respectively, which suggests that ‘Yu Her Pau’ has the potential to increase fruit set by increasing the effectiveness of pollination and fertilization especially the leafy inflorescence. In: C.M. Lin (ed.). Notably, our results showed that a leafy inflorescence did not increase fruit yield, with a smaller number of fruit set in comparison with a leafless inflorescence. 22 333 345, Menzel, C.M. Feizixiao) grown in an orchard in the South Subtropical Crops Research Institute (Zhanjiang, China) were selected, and 20 similar-sized inflorescence clusters from each tree were tagged. The inflorescence is a compound raceme, bears small, off-white unisexual and bisexual flowers. In recent years, several early-maturing litchi cultivars have been developed for benefits of litchi industry. Menzel and G.K. Waite (eds.). 114 268 274, Chang, J.C. & Lin, T.S. In: L.R. Therefore, keeping vegetative flushes with different maturation before floral induction is crucial p. 5–33. Litchi can be grown in every district of Bangladesh, however, presently it is being grown mainly in rajshahi, rangpur, dinajpur, jessore, kushtia, mymensingh and narayanganj. Meet.
