提高作物的光能利用率,是一项大幅度增产的重要措施。今后的育种工作应注意从这方面着手,选育高光效的高产品种。要选育高光效品种,必须测定一些代表高光效的生理指标。但由于需要复杂的仪器设备和较繁的方法,受条件限制较大,因此寻找一些与它相关性高的生态性状很有必要。有了简单易行的高光效指标,便于群众开展高光效育种工作。为此,我们于1978年对43个小麦材料进行了光合速率的测定和形态观察,并进行了相关分析。结果证明,用某些形态性状,
Increasing the utilization of light energy in crops is an important measure to increase production substantially. Future breeding work should be noted from this regard, breeding high-yielding high-yielding varieties. To breed high light efficiency varieties, some physiological indices that represent high light efficiency must be determined. However, due to the complicated equipment and complicated methods, it is necessary to find some ecological traits related to it because of the limited conditions. With a simple high-efficiency indicators, to facilitate the masses to carry out high light efficiency breeding work. To this end, we measured the photosynthetic rate and morphology of 43 wheat cultivars in 1978 and analyzed the correlation. The results show that with some morphological traits,
