油茶芽苗砧嫁接口愈合与内源激素的关系

o find out healing mechanisms, endogenous hormones including GA3, IAA, ABA and ZR were determined by ELISA, measured during the development of the nurse seedling grafted union in Camellia oleifera. The results showed that GA3, IAA, ABA and ZR all played an important role in the healing of Camellia oleifera grafted union. GA3/ZR、ZR/IAA and ABA/ZR had significant effect on the healing, and ZR / IAA mainly regulated the morphological direction, GA3 / ZR and ABA / ZR affected the morphological formation of healing in the grafted union. The correlation analysis showed that the correlation between ZR and GA3 was the highest in the four types of endogenous hormones, which reached the extremely significant level. The level of endogenous hormones can be regulated by GRelationship between endogenous hormone levels and the development of the nurse seedling grafted union in Camellia oleifera, A3. The results will provide the theoretical guidance for the scientific research and the application of the nurse seedling grafting in Camellia oleifera.
