摘要

Radiotracer (14C) experiments were conducted to develop a sustainable pruning strategy in guava (Psidium guajava L.) based on the source-sink carbon partitioning (14C) dynamics. 14C-photoassimilate transfer from the source leaves followed the following scheme based on the respective sink’s demand i.e. fruit on the source leaf branch > shoot and foliage of the source leaf branch > fruit on the adjacent branch > shoot and foliage of the adjacent branch. This study clearly indicates that the source leaves adjacent to the developing fruit play a crucial role in governing the fruit growth and development. Thus, for an efficient canopy management and for a sustainable year to year productivity, instead of pruning an overall outer canopy, the alternate pruning-fruiting strategy in guava can be so designed to remove the branches on which the fruits are not desired, leaving intact the branches targeted to bear the fruits and vise-versa in the succeeding year.
