采用2.5%的聚乙二醇-6000对沙棘(Hippophae spp)种子进行预处理。结果显示:聚乙二醇(PEG)预处理能提高沙棘种子的发芽率和发芽势,缩短发芽时间,并且能增加萌发种子的呼吸强度、过氧化氢酶的活性、可溶性糖的含量,促进沙棘种子萌发。
Hippophae spp seeds were pretreated with 2.5% polyethylene glycol-6000. The results showed that pretreatment with polyethylene glycol (PEG) could increase the germination rate and germination potential of seabuckthorn seeds and shorten the germination time, and also increase the respiration rate, catalase activity and soluble sugar content of germinating seeds and promote seabuckthorn seed sprouting.
