Research Progress on the Mechanism of Regulating the Number of Tomato Locules
The number of tomato locules is closely related to the incidence of malformed fruits.Increasing tomato locule number resulting larger fruit size but multi-locule fruit will develop to malformed fruits easily.Multi-locule malformed fruits often happening when tomato cultivated at horticultural facilities in winter and spring,which seriously affects the quality and economic benefits of tomato.The number of carpels determines the number of locules.The number of carpels is determined by the size of flower meristem.The division and differentiation of meristem is very important for the number of tomato locules.This review summarizes the progress of factors affecting the locule number of tomato were reviewed from the aspects of locus,genes,temperature,light,nutrients,plant hormones,in order to provide reference for efficient cultivation and quality breeding of tomato.
