插穗由于材料短小,本身养分不足,再生能力和分生机能都受一定时间的限制。因此能否及时或提前利用其有限的生长素促成不定根的生长,是插穗成活的关键。兹将促进插穗生根的几种效果较为明显的方法分述于下: 1.采用硬枝扦插时,可先用30℃左右的温水浸泡,以增强枝条内酶的活性,促进营养物质转化,加速愈合生根。
Cuttings due to short materials, their lack of nutrients, regeneration and meristematic functions are subject to certain restrictions. Therefore, whether timely or early use of its limited auxin to promote adventitious root growth is the key to survival of cuttings. Here are some of the more obvious ways to promote the rooting of cuttings: 1. When hardwood cutting is used, it can be soaked in warm water at about 30 ° C to enhance the enzyme activity in the shoots and promote the transformation of nutrients and accelerate Healing roots.
