本试验通过C~(14)示综法测定,穗部吸收的CO_270%被运送到粒中积累起来。有关这方面的资料前人亦提供了许多,尽管由于测定的方法不同而所得数据并不完全相同,但均可证明,大、小麦穗子能营光合作用且对籽粒有供应养分的作用。就大麦和小麦穗子对籽粒养分的供应而言,两者有明显的区别。据Thorne用红外线气体分析仪的测定,春大麦(PlumageArcher)在出穗后第10日,穗的光合作用速
The test by C ~ (14) shows that the synthesis method, the ear absorption of CO_270% is transported to the grain accumulation. Many sources have also been provided in this regard. Although the data obtained are not identical due to the different methods of determination, it can be demonstrated that large and small wheat ears can photosynthesis and provide nutrients to the grain. In terms of the supply of grain nutrients to barley and wheat ears, there is a clear distinction between the two. According to Thorne’s determination with an infrared gas analyzer, on the 10th day after ear emergence, the photosynthesis rate of the ear of PlumageArcher
