不同成熟期板栗品种(系)种子发育期主要营养物质与内源激素含量的动态变化
Dynamic Changes of Main Nutrients and Endogenous Hormones in Seed of Different Mature Period Chinese Chestnuts During their Seed Development
摘要
Abstract
To explore the maturity mechanism and the method of regulating mature period of chestnuts,the starch, soluble sugar, soluble protein, Vc, IAA, ZT, GA3, ABA and Eth of different mature period Chestnuts (0212, E two,0214,0206,0204 and E one) were measured and analyzed. The results showed that the change tendency of main nutrients'accumulation were analogous. The starch and the soluble sugar were accumulated greatly before maturation 20 ～ 30 d. The contents of starch, soluble sugar, soluble protein and Vc were showed that the early maturation varieties ＞ the middle maturation varieties ＞ the later maturation varieties. The other results showed that the decrease of IAA, ZT and GA3 and the increasing of ABA and Eth were beneficial to the accumulation of the starch, soluble sugar, soluble protein and Vc. IAA,ABA were the key factors, especially the IAA, for chestnuts nutrients accumulation, but the balance of all Endogenous Hormones were most important. And last, significant difference in maturation time of different chinese chestnuts were result from the different starting change days beforte maturation and the lasting times of endogenous hormones.关键词
