3种无核荔枝果实发育过程中内源激素含量变化动态
Dynamic Changes of Endogenous Hormone Contents in the Pericarp of Seedless Litchi during Fruit Growth and Development
摘要
Abstract
The changes of endogenous indol-3-acetic acid (IAA), gibberellins (GA3), zeatin (ZT) and abscisin acid (ABA) contents in 3 cultivars of seedless litchi fruit during fruit growth and development were determined by high performance liquid chromatography ( HPLC), The relationship between contents of endogenous hormones and seedless litchi fruit growth and development were compared with that of seedy litchi, and the reason for seedless litchi fruit was also discussed. The results showed that the change patterns of GA3 and ABA in seedless litchis were about equal to that of seedy litchi during the period of fruit growth and development, and the changes trend of ZT and IAA showed great differences between seedless and seedy litchis. It was suggested that either the different phytohormone regulations of fruit growth and development existed respectively in two different types of litchis, or fruit growth and development was more closely related to the content of GA, and ABA. Furthermore, High content IAA and low levels ZT in fruit of seedless litchi may be an important reason of seedless.关键词
