4种生长调节剂对高粱矮化效果的影响

Effects of Four Plant Growth Regulators on the Dwarf of Sorghum

对高粱喷施不同剂量的矮壮素、乙烯利、多效唑、矮脚虎4种生长调节剂,研究其对高粱矮化效果的影响。结果表明,4种生长调节剂对高粱矮化都有不同程度的促进作用,矮化效果从大到小依次为乙烯利>矮壮素>矮脚虎>多效唑。

The effects of four plant growth regulators of CCC,ethephon,multi-effect azole,tifdwarf solution for field test was studied,to prove the their effect of different growth regulators on the yield and dwarf sorghum.The results have shown that four growth regulators have different degrees of promoting effect on sorghum dwarf,the role of sorghum dwarfing was in an order of ethephon ＞ cycocel ＞tifdwarf ＞ multi-effect azole.
