9个冬种甘薯不同发育时期品质变化
Quality Dynamic Changes of Nine Sweetpotato Varieties in Different Developmental Stages
摘要
Abstract
The purpose of this study was to investigate the phenotypic and main quality changes of nine yellow-fleshed sweetpotato(YFSP)varieties at different development stages,and to provide a theoretical basis for the breeding of fresh sweetpotato.Nine winter YFSP varieties were used as materials.The diameter,length,weight,flesh color,dry rate,starch,and soluble sugar content of sweetpotato at five development stages were measured and analyzed.The results showed that the diameter,length,weight and dry rate of single potato increased continuously during the development process.The growth rate of sweetpotato length of'Guangshu 79'was the fastest at 45-105 d,and that of'Anna'was the fastest at 135-165 d.The highest rate of increase in diameter and single sweetpotato weight was'Mashali'.The dry matter rate of'Guangshu 79'increased the fastest.The soluble sugar content showed a downward trend during development,and'Guangshu 79'showed the fastest decline.With the increase of starch content,'Guangshu 79'increased rapidly in the early growth period of 45-105 d,and'Anna'increased fastest in 135-165 d.The study found that the length,diameter,single root weight,dry rate and total starch content of YFSP tubers increased gradually with the growth and development period,and the content of soluble sugar decreased gradually.The rapid development and growth periods of different varieties of sweet potato were different.关键词
