Study on the Cumulative Change Rule of Tuberous Root Element in Different Varieties of Cassava

Sugarcane Research Institute,Fujian Academy of Agricultural Sciences

摘要

摘要: 以F15、F901、G15、瑞士N4和GR911等木薯品种为材料,在块根膨大期对其干物质、蛋白质、淀粉、可溶性总糖含量以及收获期对产量进行测定。结果表明:木薯块根干物质和淀粉的积累与生长期呈一定的正相关,随着时间的延长而升高;蛋白质含量随着时间的延长均呈先升后降的趋势,在11月份达到最高值;依据淀粉含量变化和块根产量表现,F15和F901淀粉含量连续保持上升趋势,建议采收期在1月份,G15和瑞士N4淀粉含量在12月份增长缓慢或不增长,建议采收期在12月份。

Abstract: Using F15,F901,G15,Switzerland N4and GR911cassava varieties as materials,the dry matter content,protein content,starch content,soluble sugar content and yield in harvest time were determined during tuberous root of enlargement stage.The results showed that the dry matter and starch accumulation of tuberous root were positively correlation with growth period,which contents of testing varieties(except F901)were gradually increased with time prolonged.While the protein content were first rises then falls during the growing season,and the peak happened at November.According to the performance of starch and yield,the recommended harvest times of F15,F901,GR911were January,which starch content kept continuous rising trend.While the recommended harvest time of G15and Switzerland N4 were December,which starch content increased slowly or remained unchanged during December.
