Effect of CPPU on growth and endogenous phytohormonne contents of balsmpear (Momordica charantia L. ) fruit.
CPPU对苦瓜果实生长和内源激素含量的影响

CPPU application test of Momordica charantia L. was conducted in variety of "Kaihua Changbai". It was shown that application of CPPU to the ovary at anthesis within the concentration of 10~50 mg/L accelerated fruit growth by increasing the length, diameter and fresh weight of fruits, while 100 mg/L inhibit fruit growth. The HPLC analysis showed that the endogenous ZT content of fruit was lowered and the endogenous ABA content was improved by CPPU treatments at the concentration of 20 and 100 mg/L, and that the endogenous contents of IAA and GA 3 were significantly improved by application of CPPU at 20 mg/L, reaching a peak value 6 days after anthesis.
