Timing of the inhibitory effect of fruit on return bloom of ‘Valencia’ sweet orange (<i>Citrus sinensis</i> (L.) Osbeck)

Abstract

In 'Valencia' sweet orange, fruit inhibits flowering from the time it completes its growth. Neither soluble sugar content nor starch accumulation in leaves due to fruit removal was related to flowering intensity, but some kind of imbalance in nitrogen metabolism was observed in trees tending to flower scarcely.
