植物受到物理刺激后常有改变其生长状况的反应。如牵牛花的蔓、豌豆和葡萄的卷须等都有与主茎反方向生长的现象。圆叶茅膏菜在昆虫接触其叶片时叶片马上向中心卷曲。这是植物对物理刺激的生理生态反应。把这种反应用到实践中的有:盆栽时用铁线卷曲干和枝进行整形;种植菊花时,用人工使菊花高度一致。这些都是接触刺激抑制生长的方法,其作用是通过接触刺激增加植物体内的乙烯成分,从而抑制徒长,促进
Plants are often subjected to physical stimuli to change their growth response. Such as the morning glory of the vine, peas and grape tendril and so have the opposite growth of the main stem phenomenon. Circular leaf sundew in the insect contact with its leaves when the blade immediately curled into the center. This is the physiological and ecological response of plants to physical stimuli. The practice of this response are: pots with wire curly dry and branches for plastic surgery; planting chrysanthemums, artificial chrysanthemums highly consistent. These are contact stimuli to inhibit the growth of the method, its role is to contact the stimulus to increase the plant’s ethylene content, thereby inhibiting leggy and promoting
