采用酶联免疫法（ＥＬＩＳＡ）测定了南亚热带干热多日照河谷（Ｅ１）和北亚热带湿热少日照河谷（Ｅ２）两类生态型区的金冠苹果７种器官内源激素ＩＡＡ、ＧＡ、ＺＲ、ＡＢＡ含量和不同生长时期叶片各激素的含量变化。结果表明，Ｅ２型区苹果茎尖和叶片ＩＡＡ、ＧＡ、ＺＲ含量，幼叶和芽的ＧＡ含量以及伸长中的茎、幼叶、叶、根的ＺＲ含量均显著高于Ｅ１型区，而各器官ＡＢＡ含量则显著低于Ｅ１。两类生态型区苹果的生长结果状况也呈现相应的变化。
The contents of endogenous hormones IAA, GA and ZR in seven organs of Golden Crown apple in two types of ecotypes of South Asia dry-thaw multi-sunshine valley (E1) and northern subtropical moist heat sunshine valley (E2) were determined by enzyme linked immunosorbent assay (ELISA) ABA content and leaf hormone content in different growth stages. The results showed that the content of IAA, GA and ZR, the GA content of young leaves and buds and the ZR content of stems, leaves, leaves and roots in E2 type were significantly higher than those in E1 type. ABA content was significantly lower than E1. The growth status of two types of ecotypes also showed corresponding changes.
