在苏联与论参预之下,于1929年中出现“春化”的理论,这一理论系李森科在其工作中发现。冬性植物从其发育特性转变为春性的发育现象包括在这一术语的内容之内。如果春化在自然条件下完成,则温度为其决定的因素,此时秋播植物经受适当寒冷的长期作用。在这一情况下的春化可称为温度春化。在另一状况下,能够以其他的主导因素进行春 Under the intervention of the Soviet Union and its theory, the theory of “vernalization” appeared in 1929, and this theory was discovered in his work by Lysenko. The development of winter plants from their developmental traits to their springiness is included in the context of this term. If vernalization is done under natural conditions, the temperature is a factor in its decision, at which time the autumn plant will withstand the long-term effects of proper cold. Vernalization in this case can be called temperature vernalization. In another situation, the other dominant factors can be spring
