1.水培的小麦于抽穗后不同时期剪除不同数量的根系,在营养元素供应与否的情况下,探索根系对于叶片活力的影响。2.根系减少到一定数量之后,叶片的活力提早丧失,容易衰老。根系减少的时期愈早,其作用愈大。3.在保证植株维持水分平衡的条件下,根系在植株发育后期对叶片活力的影响,主要不是通过营养元素的供应,而是根系的其他机能起作用。4.根系是决定叶片里蛋白质多少的主要因素,根系愈少,叶片的蛋白质减少愈迅速,叶片愈易失去活力。5.控制根系的多少,可以影响植株成熟快慢和种子的饱满程度。
1. Hydroponic wheat cut different numbers of roots at different stages after heading, and explored the effect of root on leaf vigor under the condition of nutrient supply or not. 2. Root reduced to a certain amount, the early loss of leaf vitality, easy to aging. The earlier the period of root reduction, the greater its effect. 3. Under the condition of keeping the water balance of the plant, the effect of the root system on the leaf vitality at the late stage of the plant development is mainly not through the supply of nutrient elements, but other functions of the root system. 4. The root system is to determine the number of leaf protein in the main factors, the less root system, the more rapid reduction of protein in leaves, leaves the more easily lose their vitality. 5. Controlling the number of roots, can affect the speed of plant maturity and seed fullness.
