不同基因型甘薯直链淀粉含量差异研究
Genotype variation in amylose content of sweetpotato
摘要
Abstract
To study on rapid determination of amylose content in sweetpotato starch,the difference were assayed for genotypes variation in amylose content of sweetpotato.The results showed that it was highly correlated between true amylose and apparent amylose using the method（r=0.9992）,the error of five various samples of sweetpotato amylose content using degreasing were less than or near 2% of samples by using 0.50g,non-degreasing,which was accepted according to GB8648-87,indicated it was fit to the determination of amylose content in sweetpotato starch.There were some differences of amylose content among 50 sweetpotato varieties,which ranged from 14.22% ~ 35.12%,the largest coefficient of variation from yellow-flesh varieties,which was the most likely to be screened with high or low amylose varieties.关键词
