detopping in some plants reduces vegetative growth and increases transporting of photosynthate materials to specific sinks such as seeds. to study the effects of detopping removal and plant density on yield and yield components of faba bean (vicia faba l.), an experiment was carried out as a factorial arrangement based on a randomized complete block design with three replications at farm resear...

Camellia japonica L. is an evergreen shrub whose cultivars are of great ornamental value. In autumn, after flower bud differentiation, dormancy is initiated. As in many other spring flowering woody ornamentals, winter low temperatures promote dormancy release of both flower and vegetative buds. However, warm spells during late autumn and winter can lead to unfulfilled chilling requirements lead...

Flowering of many plants is induced by environmental signals, but these responses can depend on the age of the plant. Exposure of Arabidopsis thaliana to vernalization (winter temperatures) at germination induces flowering, whereas a close perennial relative Arabis alpina only responds if exposed when at least 5 weeks old. We show that vernalization of these older A. alpina plants reduces expre...

Salak palms (Salacca spp.) are important fruit species in Southeast Asia, but the morphogenesis of their reproductive organs is unknown. To observe female gametogenesis, pistil S. wallichiana and subsequent fertilization were observed. The ovary contained three ovule primordia months before flowering (BF). one mono-nucleate megaspore at center degenerated megaspores on chalazal side two BF, a e...
