摘要

Two varieties of Jerusalem artichoke (early maturing variety Qingyu No.1 and middle maturing variety Qingyu No.2),which were bred independently by Research and Development Center of Jerusalem Artichoke,Qinghai Academy of Agriculture and Forestry,were used as materials,and the content and dynamic changes of three kinds of carbohydrates (sucrose,glucose and fructose) in various organs of Jerusalem artichoke in different periods in two natural habitats (water plain and low hill dry land) were studied.The results showed that the content of the three kinds of carbohydrates in Qingyu No.1 and Qingyu No.2 in the water plain and low hill dry land was relatively high in late June and late August.The total content of the three carbohydrates in Qingyu No.1 peaked earlier than that of Qingyu No.2.The total content of the three carbohydrates in the water plain peaked earlier than that of the low hill dry land.In the whole growth period,the total content of the three carbohydrates in the stems and roots of Jerusalem artichoke was higher than that of the leaves.In the leaves,fructose accumulation was relatively obvious in the whole growth period,and the content was high,followed by glucose.In the stems and roots,fructose content was high,followed by sucrose.In the tubers,glucose accumulation was obvious,and sucrose content was lower than glucose and fructose content.When the tubers were harvested,fructose content was high.
