栽培措施对高油大豆产量及品质性状的影响

Environmental effect on yield and quality of high-oil soybean

采用4因素4水平正交试验,研究了高油大豆品种、密度、施肥水平、播期对产量和品质的影响。结果表明,高油大豆的脂肪、蛋白质及蛋脂总量主要受品种自身的遗传因素影响,其次是播期的影响;而施肥水平对高油大豆的产量影响较大;17种氨基酸中,除丝氨酸、胱氨酸和蛋氨酸含量受品种因素影响较大外,其它14种氨基酸及氨基酸总量均受播期因素影响较大,而各种脂肪酸含量主要是由品种自身的遗传因素控制的。

The effects of variety, density, fertilizer levels and sowing date on the high-oil soybean yield and quality were studied in field experiment. In this research, oil content, protein content and total content of protein and oil of high-oil soybean were determined mainly by genetic factors, and second by sowing date. Fertilizer level had greater effect on high-oil soybean yield. Among the factors which affected 17 amino acids, Ser, Cys and Met contents were affected more by their genetic factors; other 14 amino acids and the total amino acid contents were affected mainly by sowing date. All fatty acid contents were controlled mostly by their genetic factors.
