| Abstract: | Some aspects related to fruit growth and development of "Younai" (Prunus salicina Lindl var. cordata J Y Zhang et al) were studied, and the results showed as follows. The accumulations of soluble carbohydrates (including fructose, glucose, sorbitol and sucrose) in flesh showed their characteristic patterns in different special phase of fruit growth. In the initial rapid growth stage, the concentrations of soluble carbohydrates increased rapidly and paralleled the peak of growth rate, then decreased relatively during retarded growth phase. At the later stage of retarded growth, the soluble carbohydrates were accumulated markedly and then decreased with the increasing of the growth rate. When fruit, its growth rate increased at a second time and then went into maturation, the concentrations of soluble carbohydrates, especially of fructose and glucose, increased rapidly. The fluctuations of different endogenerous hormone showed their own special features, during the growth and development of fruit. Endogenerous ZRs and ABA were positively correlated to the first peak of growth rate and accumulation of soluble carbohydrates, but diH]ZRs held a low level at this stage. The concentrations of CTKs (mainly diH]ZRs) increased markedly and the peaks paralleled the soluble carbohydrates at the later stage of retarded growth, which suggested that cytokinins probably triggered the subsequent rapid growth of pericarp. ABA was correlated to the subsequent rapid growth and the accumulation of soluble carbohydrates (especially fructose glucose). Mechanism of fruit growth and development in Nai and its correlation to CTKs and ABA were discussed in this paper |
