摘要: 本试验旨在研究我国不同转基因棉花品种棉籽的营养成分和棉酚含量并对其进行相关性分析。采集全国9个主要转基因棉花品种的棉籽,测定营养成分和棉酚含量。结果表明,9种转基因棉花的棉籽中主要营养成分粗蛋白(CP)、粗脂肪(EE)、酸性洗涤纤维(ADF)、钙(Ca)、磷(P)平均含量分别为(27.89±1.66)%,(17.39±1.66)%,(23.34±1.14)%,(0.16±0.03)%和(0.36±0.04)%,游离棉酚、总棉酚平均含量分别为(3 970.35±1 109.45),(5 996.19±1 002.43)mg/kg,总棉酚跟EE相关系数为0.872 1,回归方程为y=525.162x-3 134.62(R2=0.760 5)。转基因棉花棉籽主要营养成分及棉酚含量变异较大,转基因棉花棉籽的棉酚含量与传统棉花棉籽无差异,EE含量与总棉酚含量相关性最高。

Abstract: This experiment was designed to study the nutritional composition and gossypol content of different transgenic cottonseed in China and then analyse their correlation.Samples of transgenic cottonseed of 9 main different varieties were collected and then their nutritional composition and gossypol content were determined.The result showed that:The average content of CP,EE,ADF,Ca and P of transgenic cottonseed were(27.89±1.66)%,(17.39±1.66)%,(23.34±1.14)%,(0.16±0.03)% and(0.36±0.04)% respectively,the average content of free and total gossypol were(3 970.35±1 109.45),(5 996.19 ±1 002.43)mg/kg respectively.The correlation coefficient of total gossypol and EE was 0.8721,and the regression equation of the two was y=525.162x-3 134.62(R2=0.760 5).The conclusion was:the nutritional and gossypol content of transgenic cottonseed showed big C.V;the content of free gossypol between transgenic and non.transgenic cottonseed had no significant difference;correlativity between EE content and total gossypol content was the highest.
