摘要:

以‘大地95’、‘京华165’、‘山油2号’3个甘蓝型油菜品种为材料,比较分析不同海拔条件对油菜农艺性状和品质性状的影响。结果表明:随海拔高度的增加,油菜全生育期延长,株高、分枝高度、分枝数、单株角果数、每果粒数减少,单株产量和产量降低,千粒重增加;蛋白质含量降低,含油量增加,硫甙和芥酸在不同品种间表现不一致。相关性分析表明:海拔高度与生育期显著正相关,与株高和单株产量显著负相关,相关系数分别为0.519、-0.548、-0.528;海拔高度与蛋白质显著负相关,与含油量、硫甙、芥酸正相关,相关系数分别为-0.590、0.262、0.161、0.138。

Abstract:

Three Brassica napus L. varieties, ‘Dadi 95’, ‘Jinghua 165’, and ‘Shanyou 2’, were used as materials to analyze the effects of different altitudes on agronomic and quality traits of rapeseed. The results showed that: with the increase of altitude, the whole growth period of rapeseed was prolonged, the plant height, branch height, number of branches, number of siliques per plant and number of seeds per silique decreased, so did the yield per plant and yield, while the thousand-grain weight increased; the protein content decreased and oil content increased, and the content of glucosinolate and erucic acid showed inconsistence among different varieties. Correlation analysis showed that the altitude was significantly and positively correlated with the growth period, and significantly and negatively correlated with the plant height and yield per plant, the correlation coefficient was 0.519, -0.548, and -0.528 respectively; the altitude was significantly and negatively correlated with the protein content, and positively correlated with the content of oil, glucosinolates and erucic acid, the correlation coefficient was -0.590, 0.262, 0.161, and 0.138, respectively.

Key words: altitude, Brassica napus L, agronomic traits, quality traits, correlation analysis
