Correlation Analysis Between Fruit Formation and Endogenous Hormone Contents in Glehnia littoralis
摘要
Abstract
In order to clarify fruits formation period of Glehnia littoralis and the dynamic changes of 4 endogenous hormone contents,and analyze the correlation between fruit formation and endogenous hormone content,the contents of indole-3-acetic acid(IAA),zeatin(ZT),gibberellin a3(GA3)and abscisic acid(ABA)in fruits of Glehnia littoralis were determined by high performance liquid chromatography at different developmental stages.The results showed that the fruits formation of Glehnia littoralis could be divided into 3 stages including milky ripeness stage,middle maturity stage and full-ripe stage.during the development of fruit,the longitudinal diameter and transverse diameter of fruit showed change trend with fast-slow-fast,and the water content increased first and then decreased,and the 100-grain weight significantly increased with reaching 2.66 g at maturity stage.The contents of ZT and IAA showed trend of increasing-decreasing-increasing-decreasing,and the content of GA3 showed a decreasing-increasing-decreasing trend.At the end of fruit mature period,ABA was detected,which the content was 46.02 ng·g-1.The correlation analysis showed that the content of ZT significantly positively correlated with fruit transverse diameter and negatively correlated with fruit shape index,while the correlations between other traits were not significant.The above results preliminarily revealed the changes of each trait during fruit formation and the correlation among these traits,which provided a theoretical basis for hormone regulation of fruit formation and improvement of grain weight.关键词
