摘要: 通过对不同品种彩色稻含氮化合物含量的比较与相关性分析,筛选出增香潜力大的彩色功能稻种质资源,为彩色稻的增香研究提供可行性技术参数。结果表明,各品种糙米的全氮含量高低依次为上农红粳>上农黑糯>红香玉>白巨胚>绿稻>黑巨胚>红玉巨胚;可溶性糖含量高低依次为上农红粳>红玉巨胚>红香玉>白巨胚>绿稻>红巨胚>上农黑糯;其可溶性蛋白质含量高低依次为红玉巨胚>黑巨胚>白巨胚>上农黑糯>绿稻>上农红粳>红香玉;L-脯氨酸含量高低依次为白巨胚>绿稻>红玉巨胚>上农黑糯>红香玉>黑巨胚>上农红粳;并且各品种间各生理性状差异极显著。上农红粳、上农黑糯、红玉巨胚、绿稻糙米的L-脯氨酸含量与糙米总氮含量正相关;上农黑糯、绿稻、黑巨胚、红玉巨胚的L-脯氨酸含量与可溶性糖含量负相关(其中绿稻为显著负相关);上农红粳、上农黑糯、绿稻、红玉巨胚谷粒颖果的L-脯氨酸含量与可溶性蛋白含量负相关,并与总氮含量正相关。因此,上农黑糯、绿稻、上农红粳、红玉巨胚的增香潜力比较大。

Abstract:  In order to find the colored-rice cultivars with stronger aroma synthesis potential among the 7 rice cultivars, nitrogen-containing compounds such as L–proline concentration, total nitrogen concentration, soluble protein concentration, soluble sugar concentration of brown rice were compared and analyzed. The results showed that: according to the total nitrogen concentration in decreasing order, the colored-rice cultivars numbered as Shangnonghongjing, Shangnongheinuo, Hongxiangyu, Baijupei, Lvdao and Heijupei, Hongyujupei. According to the soluble sugar concentration in decreasing order, the colored-rice cultivars numbered as Shangnonghongjing, Hongyujupei, Hongxiangyu, Baijupei, Lvdao, Heijupei and Shangnongheinuo. According to the soluble protein concentration in decreasing order, the colored-rice cultivars numbered as Hongyujupei, Heijupei, Baijupei, Shangnongheinuo, Lvdao, Shangnonghongjing and Hongxiangyu. According to the L-proline concentration in decreasing order, the colored-rice cultivars numbered as Baijupei, Lvdao, Hongyujupei, Shangnongheinuo, Hongxiangyu, Heijupei and Shangnonghongjing; and almost all the differences of the cultivars were significant (p<0.01). What’s more, L-proline concentration of cultivars named Shangnonghongjing, Shangnongheinuo, Hongyujupei and Lvdao correlated their total nitrogen content positively, while L-proline concentration of cultivars named Shangnongheinuo, Lvdao, Heijupei and Hongyujupei correlated their soluble sugar concentration negatively, especially the cultivars named Heijupei and Lvdao correlated significantly; L-proline concentration of cultivars named Shangnonghongjing, Shangnongheinuo, Lvdao, Hongyujupei correlated their soluble protein concentration negatively and correlated their total nitrogen positively. In a conclusion, the cultivars named Shangnongheinuo, Lvdao, Shangnonghongjing and Hongyujupei have the stronger aroma synthesis potential than others.
