全国10个不同生态型的小麦品种籽粒蛋白质含量变动于8.37~12.72%之间,这些品种在贵州生态条件不同的3个点(贵阳、遵义、铜仁)种植后,籽粒蛋白质含量比原种子有所增加,春播的小麦籽粒蛋白质含量略高于秋播。蛋白质含量与日平均温度之间呈正向联系;与降雨量呈负向联系,其紧密程度视品种的不同而异。3个生态点的小麦籽粒赖氨酸含量的平均值比原种子高,冬性品种比春性品种赖氨酸含量高。海拔较低的铜仁地区赖氨酸含量最高,其次是遵义和贵阳花溪。小麦赖氨酸含量与日平均温度呈极显著正相关(r=0.6761).若以籽粒干重的百分数表示,蛋白质与赖氨酸含量呈正相关(r=0.5663)。
The grain protein content of 10 ecotypes of wheat varieties varied from 8.37% to 12.72% in China. After they were planted at three different ecological conditions (Guiyang, Zunyi and Tongren) in Guizhou, the grain protein content of the cultivars was higher than that of the original seeds Increase, spring sowing of wheat grain protein content slightly higher than autumn sowing. The protein content is positively correlated with the daily average temperature, negatively correlated with rainfall, and the degree of closeness varies with the species. The average lysine content of wheat grain in the three ecotypes was higher than that of the original seed, while the winter wheat varieties had higher lysine content than the spring varieties. The highest level of lysine was found in Tongren with lower elevation, followed by Huaxi in Zunyi and Guiyang. There was a significant positive correlation between lysine content and daily average temperature (r = 0.6761) .When the percentage of kernel dry weight was expressed, protein and lysine content were positively correlated (r = 0.5663).
