植物间抑制现象乃是一种由彼此间释放的抑制物质的化学作用造成的。高等植物视其发育及生理状态,可能全部器官同时参与这种抑制作用,也可能仅有部分器官参与。在适宜生育条件下,植物对彼此间的这种抑制现象具有忍耐性,而在较差或不良条件下,则表现出抑制效应。抑制物质来自植物体所有器官.因而全部器官均可能受其影响,其中尤以根反应
The phenomenon of plant-to-plant suppression is caused by the chemical interaction of the inhibitory substances released from each other. Higher plants, depending on their developmental and physiological status, may all organs participate in this inhibitory effect at the same time, or only part of the organs may participate. Under suitable growth conditions, plants have patience with this inhibition of each other, while in poor or poor conditions, they show inhibitory effects. Inhibitors come from all organs of the plant, so all organs may be affected, especially root reactions
