采用L25(56) 正交试验设计研究了不同浓度的多效唑( 简称MET) 和矮壮素( 简称CCC) 对小麦花培苗在常温下安全越夏的作用。结果表明:在小麦花培苗的壮苗培养基中加入2 ~3 mg/LMET和2 ~3 mg/LCCC 均可使小麦花培苗安全越夏。MET的效果比较明显,CCC 的效果比较平稳。MET用药量比较严格,超过3 mg/L,出现严重药害
L25 (56) orthogonal design was used to study the effect of different concentration of paclobutrazol (MET) and chlormequat (CCC) on the safety of wheat seedlings at room temperature. The results showed that adding 2-3 mg / LMET and 2-3 mg / L CCC in the seedling culture medium of wheat flower seedlings could make the summer flower seedlings safer. The effect of MET is obvious, the effect of CCC is relatively stable. MET dosage is more stringent, more than 3 mg / L, serious injury occurs
