生长调节剂对根用菊苣先期抽薹的影响

Effects of Growth Regulators on Early Bolting of Root Chicory

摘要: 为解决根用菊苣生产中先期抽薹的问题,本研究以比利时根用菊苣为材料,研究了矮壮素、比久、多效唑3种生长调节剂对菊苣先期抽薹的影响。结果表明:450mg·kg^-1浓度的矮壮素可以有效抑制菊苣先期抽薹,菊苣抽薹率为26.84%,比对照低52.31%。因此生产上建议在菊苣苗2～3片真叶时喷施450mg·kg^-1的矮壮素抑制根用菊苣的先期抽薹。

Abstract: In order to reduce the early bolting in the production of root chicory,the effects of three growth regulators,chlormequat,B₉ and paclobutrazol,on early bolting of Belgian root chicory were studied.The results showed that 450 mg·kg^-1 could effectively inhibit the early bolting of chicory,and the bolting rate of chicory was 26.84%,and decreased 52.31%than the control.It is suggested to spray 450 mg·kg^-1 chlormequat on 2-3 true leaves of chicory seedings to inhibit the early bolting of root chicory.
