植物的生长发育过程,受植物体内多种微量激素同时或交错地相互作用的控制。人们在运用生长物质素控制植物的生长发育的实践中,发现有时仅用一种生长物质不能实现自己的愿望,而混用两种或多种生长物质却能取得满意的结果,这种增效现象称之“协同作用”。此外,还发现植物体内的某种生长物质,因受气温、湿度、光照及肥料等的影响,其效果有时不很稳定(即所谓的多变性),而混合使用有利于克服生长物质的这种多变性。
Plant growth and development process, by a variety of plant hormones simultaneously or staggered interaction control. In the practice of using growth hormone to control the growth and development of plants, it has been found that sometimes only one growth substance can not fulfill its own wishes. However, mixing two or more kinds of growth substances can achieve satisfactory results. This synergistic effect Call it a “synergy.” In addition, it has also been found that some growth substances in plants are sometimes not very stable (so-called variability) due to the influence of temperature, humidity, light and fertilizer, etc., and the mixed use is advantageous for overcoming this kind of growth substances Variability.
