感性运动 (Nastic movements):植物对环境的非向性刺激(如光照、温度、湿度、震动)引起反应的可逆运动(刺激的方向不决定植物的运动方向) 向性运动 (Tropic movements):植物对环境的单向刺激[如光照(向光性)、水分(向水性)、化学物质(向化性)、重力(向地性)、接触(向触性)]产生的定向不可逆 运动(刺激的方向决定...
Directional and non-directional environmental cues are able to induce polar behaviors of plants, which are termed tropic and nastic movements, respectively. While molecular mechanisms underlying the directionality of tropic movements are relatively well studied, it is poorly understood how the polarity of...
Moreover, the tropic action of unilateral light may become nastic by internal diffusion of excitation. FromProject Gutenberg The employment of the term 'nastic' is, however, convenient when used in a well-defined and restricted sense. FromProject Gutenberg ...
