摘　　要：Cabrio和Opera是新型广谱杀菌剂,也是具有一定生物活性的植物生长调节剂。采用Cabrio和Opera喷洒处理大豆,研究了它们对大豆主要生理生化过程以及产量的影响。结果表明:喷施Cabrio和Opera可使大豆植株过氧化物酶(POD)和过氧化氢酶(CAT)活性显著增加;根瘤重分别比对照增加56.3%和57.6%;每荚粒数分别增加14.3%和13.6%;百粒重分别增加5.28%和5.42%;产量分别增加10.64%和7.85%;中黄13的籽粒霉变率分别下降5.07%和3.87%,而南农99-6的籽粒霉变率分别下降1.00%和0.87%。但部分性状如株高、根长、内源激素(生长素,赤霉素,细胞分裂素,脱落酸)含量、光合速率和蒸腾速率等虽有一定变化,但与对照没有显著差异。Cabrio and Opera are new broadspectrum Fungicides and plant growth regulators. They can reduce the growth of bacteria and regulate the physiological activity of plants. But their affections on soybean have not been reported. The purpose of the experiment was to investigate the growth, yield and physiological effects on different soybean cuhivars after Cabrio and Op- era treatment. The result showed that after treated with the Fungicides,the activity of peroxidase（POD） and catalase（CAT） sig- nificantly increased,the weight of nodules increased 56.3% and 57.6% ,the number of pods increased 14.3% and 13.6%, 100-seed weight increased 5.28% and 5.42% ,yield increased 10.64% and 7.85% ,respectively ,with the rate of moldy seeds decreased 5.07% and 3.87% in Zhonghuangl3 and 1.00% and 0.87% in Nannong99-6. But there were insignificant differ- ence between treated cultivars and CK in other traits such as plant height, root length, the content of auxin, gibberellin, cytokin- in and abscisic acid. In brief, Cabrio and Opera could promote growth and increase yield of soybean.
