摘要
用不同浓度的ＰｒＣｌ３浸种油松种子，对油松种子萌发及幼苗生长细胞内代射有明显影响。种子发芽率提高，发芽速度加快，幼苗根系加株高增加，单株增重，根系脱氢酶活性提高，幼苗ＳＯＤ活性及光合色素含量高于对照。ｃｈｌａ／ｂ值相对降低。几种处理浓度中０．５～１．０ｍｍｏｌ／Ｌ较好。
Chinese pine seeds were socked with various concentration of PrCl 3.The results show that effect of PrCl 3 on cell metabolism is marked. Germination and its rate, tap root, seeding height and weitht are increased. Activities of NADH and SOD, contents of the photosynthtic pigmentsare higher, and chla/b is lower than those of thecontrast, 0/5￣1.0mmol/L is better in treatment concentrations.
