60Co-γ射线辐照金柑花粉对果实生长发育及内源激素含量的影响
Effect of Irradiating Fortunella crassifolia Pollen With 60Co-γ Ray on Fruit Growth, Development and Endogenous Hormones
摘要
Abstract
In order to reduce the number of seeds of Fortunella crassifolia CV.Suichuangjingan,improve it's quality and competitiveness of the market,the pollen of Fortunella crassifolia CV.Suichuangjingan was treated with 1 000 Gy 60Co-γ ray,the pollinated it to Fortunella crassifolia CV.Suichuangjingan,and the non-irradiated pollen was used as control.The effects of radiation pollen on fruit growth,development and endogenous hormones contents were studied.The results showed that compared with the no irradiated pollen treatment,radiating pollen decreased the number of seeds of Fortunella crassifolia CV.Suichuangjingan,and the titratable acid content,total sugar content,Vc content and TSS content had no significant difference,but the fruit size and fruit weight were decreased obviously.30 d after the pollination,the endogenous of IAA,GA,ZT contents and(GA + IAA + ZT)/ABA ratio of pollen irradiation group was apparently lower than CK.The results gives a reference for the application of 60Co-γ ray radiation breeding in Kumquat.关键词
