Abstract
The photosynthate of leaf organs and non-leaf organs was important to the yield formation,and influenced the quality of wheat grains.However,a limited number of studies have been published in relationship between the photosynthesis organs and the quality of grains.In this study,five treatments of deprived flag leaf,deprived flag leaf and top 2nd leaf,shielded sheath of flag leaf,shielded ear,shielded ear and peduncle were conducted to cut off the photosynthesis sources,and then compared with the treatment of natural growth,the effects of different photosynthesis organs on the quality of grain were addressed.The results were as follows: Compared with natural growth,defoliating and shielding photosynthesis organs decreased the contents of starch,fat and iron in wheat grains and yields of starch,fat,protein,ash,phosphorus,potassium,zinc,iron and calcium in a single ear.In contrast,it increased the contents of ash,phosphorus,potassium,zinc and calcium in grains,and the protein content changed insignificantly.The effects of the non-leaf organs of wheat on the contents and yields of starch,fat,protein,ash,phosphorus,potassium,zinc,iron and calcium were stronger than leaf organs.Effects of the defoliating and shielding photosynthesis organs on the nutrition of grain in wheat indicated that the effects of photosynthesis organs on the different quality index were variable.
