自然生境下菊芋3种碳水化合物含量积累及动态变化研究.

This test chosed early variety‘Qingyu No.1'Jerusalem artichoke and mid-variety‘Qingyu No.2'two Jerusalem artichoke varieties as materials, studied the Jerusalem artichoke sucrose, glucose, fructose carbohydrates in different periods, different tube content and the dynamic change of the total in water plain and low hill dry land under two kinds of natural habitats.Results showed that: water plain and low hill dry land cropping of Qingyu No.1 and Qingyu No.2 three kinds of carbohydrate content in Jerusalem artichoke plants in late June and late August were relative taller; Three carbohydrates in Qingyu No.1 amounted to rush hour earlier than the Qingyu No.2; Water plain three total carbohydrate to achieve peak hours earlier than hill dry land; Jerusalem artichoke stem, root in the whole stages of three high relative blade to the total amount of carbohydrates; Fructose accumulation in the leaves in the whole stages were relatively obvious, the content was higher, the second was glucose; High fructose content in stem and root, followed by sugar; And accumulation of glucose in the tuber was obvious, sucrose content was lower than those of glucose and fructose, tuber harvest maturity, fructose content was higher.
