苹果果实生长发育过程中的品质变化规律
Quality Change Rule during Apple Fruit Development
摘要
Abstract
Taking Granny Smith,Fuji and Huangyuanshuai apple as the research objects,the single fruit weight,fruit shape index,fruit firmness,titratable acid and soluble solid contents at the middle and later peri-ods during fruit development were continuously measured,and their dynamic variation rules were analyzed. The results showed that the single fruit weight showed an increasing tendency with the development of fruit, and the fruit shape index showed a inapparent increasing trend.The titratable acid presented a decreasing tendency,and the decreasing rate of Granny Smith and Huangyuanshuai was about 3 times of that of Fuji.The soluble solid content showed an increasing tendency,and the differences of increasing rates among the three varieties were not larger.The tss -acid ratio showed an increasing tendency.The firmness firstly increased and then decreased with the development of fruit.The peak value appeared on August 8,which was also the start date of single fruit weight increasing rapidly.During the whole fruit growth and development process,the titratable acid content of Granny Smith was significantly higher than that of Fuji and Huangyuanshuai,and the tss -acid ratio was lower;the soluble solid content of Huangyuanshuai was higher than that of Fuji,and Gran-ny Smith possessed relatively lower soluble solid content.关键词
