摘要
以中双11号、中油821和油研10号3个不同含油量甘蓝型油菜品种为材料,比较分析同一地区不同海拔条件对油菜主要农艺性状、产量构成因素、产量和品质的影响。结果表明:随海拔高度的增加,株高、分枝高度、一级分枝、二级分枝、主序无效果数、籽粒蛋白质含量减小;主序无效果率、千粒重、籽粒含油量逐渐增加;有效角果数、果粒数、产量表现为先减小后增加。品质指标的变异分析表明,芥酸和硫甙受环境因素的影响较大。
Three Brassica napus L. varieties,including Zhongshuang No. l i, Zhongyou 821 and Youyan No. 10 were selected, and five altitude （500,637,775,959, 1100 m） were applied to study the effect of altitude and variety combinations on main agronomic traits, yield components, yield and quality of Brussica napus L. The results indicated that plant height; branches height, No. of 1 st branch, No. of 2 nd branch, ineffective pods of main stem and seed protein were decreased, percenlage of invalid pods of main stem, 1000-seed weight and oil content were increased, and pods per plant, seeds per pod and yield were increased firstly and then decreased according to the increase of altitude. Variation analysis of quality traits showed that erucic acid and glucosinolates were easily affected by environment.
