[Effects of bagging on pigment, sugar and endogenous hormone contents of Cara Cara orange flesh].
This paper studied the effects of bagging during the period from young fruit formation to fruit coloration on the contents of pigment, sugar and endogenous hormone in Cara Cara orange flesh. The results showed that bagging could significantly increase the lycopene and beta-carotene contents of matured fruit, but didn't have any effects on its GA and ABA contents. The GA content decreased rapidly during fruit-expanding period, and maintained at a lower level in the period from fruit coloration to maturing. The ABA content reached the maximum when the bag was removed, decreased rapidly then, and there was a small peak before fruit maturation. Glucose and fructose contents were decreased, while sucrose content was increased significantly. No significant change was observed in total sugar content.
