不同品种马铃薯淀粉含量随块茎直径的变化规律
Changes of starch content in different potato varieties with tuber diameter
摘要
Abstract
Three potato(Solanum tuberosum L.)varieties,namely Atlantic,Eugene,and Holland,were used as materials to deter-mine the starch content in tubers of different diameters and analyze the relationship between starch content and tuber diameter.The re-sults showed that the amylopectin content of the three tested potato varieties was significantly higher than the amylose content,indicat-ing that amylopectin was the dominant starch type,and the cortex was the main storage site for starch.The tuber diameters correspond-ing to the accumulation peaks of amylose and amylopectin contents in different parts of the three varieties were different.Before the peak,the starch content increased with the increase of tuber diameter.Except for individual cases,the differences in starch content between different diameter grades of tubers reached a significant level,showing a linear growth trend with a good correlation.The tuber starch content of atlantic was the highest,and the correlation with tuber diameter was the best,so it could be used as a key object for studying the variation law of potato starch content.Meanwhile,according to the variation law of starch content in tubers of the three va-rieties,it was concluded that there was a positive correlation between starch growth rate and starch content.关键词
