摘要

[Objective] The paper was to explore the effect of seed soaking with paclobutrazol( PP333) on early tillering and endogenous hormone content of sugarcane seedlings.[Method] With the sugarcane variety ROC22 as the experimental material,seeds were soaked in different concentrations of PP333. The number and growth of tiller were investigated,and the contents of endogenous hormones IAA,CTK,ABA and GA3 at two-leaf,four-leaf and six-leaf stages of sugarcane seedlings were measured,to study the effects of seed soaking with PP333 on early tillering and endogenous hormone contents of sugarcane seedlings.[Result] Seed soaking with PP333 could effectively improve and advance tillering occurrence of sugarcane seedlings. The suitable PP333 concentration for sugarcane tillering occurrence,growth and development was 50 mg/L. Seed soaking with PP333 significantly increased the CTK and ABA contents in leaves of sugarcane seedlings,and decreased IAA and GA3 contents. [Conclusion]The paper will provide a theoretical basis for application of PP333 in sugarcane production.
