一、赤霉素对植物的作用:根据国内外的资料,它的作用大致有以下几点:1.促进苗木生长,防止移植后的生长停滞。2.促进植物从受霜、旱害的发育停滞状态中恢复过来。3.增加桑树和茶叶的采摘次数。4.促进开花期。由于开花期的促进,而致使以往认为不能交配的品种有进行交配的可能,对品种改良起到很大作用。5.打破种子休眠,提早种子发芽和促进植物体的初期发育。6.促进植物生长开花期,特别是提早树木的采种期,为改变品种提供条件。7.增加果实产量(如葡萄、无花果),改善果实品质。8.因调节植物生长,而有可能预防某些植物的病害。二、赤霉素的应用实例:1.在国外的实验结果举例:
First, the role of gibberellins on plants: According to domestic and foreign information, its role roughly the following points: 1. Promote the growth of seedlings to prevent stagnation of growth after transplantation. 2. To promote the recovery of plants from the stagnation of the development of frost, drought damage. 3. Increase the number of mulberry and tea picking. 4. To promote flowering. Due to the promotion of the flowering stage, breeds that were previously considered unaffordable have the potential to be mated, and play a significant role in variety improvement. 5. Break seed dormancy, early seed germination and promote the initial development of plant body. 6. Promote the flowering of plant growth, especially the early planting of trees, to provide the conditions for the change. 7. Increase fruit yield (such as grapes, figs), improve fruit quality. 8. Due to the regulation of plant growth, it is possible to prevent the diseases of some plants. Second, the application of gibberellic acid Example: 1. Examples of experimental results in foreign countries:
