种子与正在生长的植株不同,能耐较高温度的影响而不致受损害。例如在短时间内将温度加热至50℃到100℃,它们的正常发芽力不会被破坏。适当的高温不仅不会损害种子,而且甚至还会使其播种品质有所改进,长成的植株也能增产。这可能由于种子受加温处理的影响,发生一定的内部变化,以后在植株的性状上和产量上反映出来。关于这种变化的性质到现在还知道得很少。根据金傑里的见解,可以推测种子的加温处理,会引起适应力的改变,并影响植株的耐热性。为了检验这个推论,我们研究了小麦种子加温处理对长成植株的耐热性的影响,关于这方面,我们 Unlike seeds that are growing, seeds can withstand the effects of higher temperatures without damage. For example, in a short time the temperature is heated to 50 ℃ to 100 ℃, their normal germination will not be destroyed. Proper high temperatures not only do not damage the seeds, but they can even improve their sowing quality and increase the yield of grown plants. This may be due to the impact of heat treatment of seeds, some internal changes occur later on the traits and yield of plants reflected. The nature of this change so far still knows very little. According to Jin Jerry’s opinion, it can be inferred that the heat treatment of seeds will cause changes in adaptability and affect the heat resistance of plants. To test this corollary, we investigated the effect of wheat seed warming on the heat tolerance of grown plants, and in this regard, we
