Abstract:
In order to study plant growth regulator chlormequat chloride (CCC) on Lufthansa bean oil crop physiological characteristics and endogenous hormone changes，in the early stage of tuber growth of Cyperus esculentus，chlorocholine chloride （CCC) with the concentrations of 0（CK）,100，500，1 000，1 500，2 000 mg?L-1 were sprayed on the leaves one time respectively to test plant height and the contents of chlorophyll and soluble sugar and endogenous hormones.The results showed that CCC with the concentration of 500-2 000 mg?L-1 could decrease the plant height，improve the content of chlorophyll and soluble sugar.The effect of soil irrigation with 2 000 mg?L-1 CCC was the best，the plant height decreased by 34.39%，the contents of chlorophyll and soluble sugar significantly increased.The plant type and quality were improved.CCC treatment with different concentrations，reducing the IAA,GA3，and ZR contents in the leaves，compared with the control；ABA content was higher than the control.GA3 and ZR content was negatively correlated with the concentration of CCC，and ABA content was positively correlated with the concentration of CCC.And CCC inhibited endogenous hormone IAA，GA3，ZR synthesis，and promote the ABA synthesis.Comprehensive analysis obtained chlormequat (CCC) at a concentration of 2 000 mg?L-1，not only could the oil Lufthansa bean lodging，but also enhancing oil Lufthansa bean photosynthetic capacity and resistance.
