中华猕猴桃果实成熟与其乙烯代谢的关系

The Relation of Ethyl ene Metabolism in Actinide Chinesis Planch cv Ripening

研究中华猕猴桃两个品种果实采后自然成熟过程中乙烯代谢发现,中华猕猴桃乙烯代谢途径遵循MET→SMA→ACC→乙烯途径,果实成熟过程中ACC合成酶、EFE形成酶协同作用好,乙烯峰值高,果实成熟快;反之则乙烯峰值低,果实软化慢.

The ethylene metabolism during fruit ripening of Actinide Chinesis planch cv (Jiang xi 79-1, Xi xia 79-1) was studied, The results showed that the ethylene metabolism pathway in Actinide Chinesis planch cv is Met→SMA→ACC→Ethylene; The better coordination with ethylene forming enzyme and Acc synthetase, the faster fruit ripening. Otherwise, the fruit ripening is slow.
