摘　　要：以苦荞品种‘威苦1号'和‘黔苦6号'为试验材料,研究不同浓度的多效唑(PPP_(333))对苦荞主要农艺性状和产量的影响。结果表明:不同浓度多效唑处理对苦荞产量有一定的影响,适宜浓度的外源多效唑喷施苦荞可提高产量,两苦荞品种均以多效唑处理质量浓度130 mg/L时产量达到最高;通过对其主要农艺性状与产量的灰色关联分析与相关分析表明,经不同浓度多效唑处理后,苦荞农艺性状中株高对产量的影响最大,其次是主茎分枝数和主茎节数。Taking ＇Weku 1＇ and ＇ Qianku 6 ＇ as the test materials,the effect of different concentrations of PPP333 on main agronomic traits and yield of tartary buckwheat were studied.The results showed that different concentrations of PPP333 had a certain influence on the yield of tartary buckwheat.The appropriate concentration of exogenous PPP333 could improve the yield of tartary buckwheat.The yield of two tartary buckwheat varieties reached the highest,when the concentration of PPP333 was 130 mg/L.Gray correlation analysis and correlation analysis were used to study the relation between main agronomic traits and yield of tartary buckwheat.The results showed that the effect of plant height on yield was the largest,and then was stem branches and stem nodes,when tartary buckwheat was treated with different concentrations of PPP333.
