落叶松枯落针叶水浸液对落叶松和云杉种子的萌发影响
Effect of aqueous extract of larch needles on seed germination of larch and Korean spruce
摘要
Abstract
The different biological effect of aqueous extract from fresh and half-decomposed needle litters of Larix olgensis on seed germination of L olgersis and Picea koraiensis was studied. The treatments of A. 0 g/L aqueous extracts from fresh and half-decomposed needle litters of L. olgensis was the best for germination of L olgensis seeds, while the treatments of 10. 0 g/L aqueous extracts from fresh needle litters of L olgensis or 0.5 - 1. 0 g/L aqueous extracts from half - decomposed needle litters of L. olgensis was the best for germination of P. koraiensis seeds. There was a big difference between the biological effect patterns of aqueous extract from needle Utters of L olgensis on seed germination of L olgensis and P. koraieiuis, it probably was the reflect of different interactive patterns between the allelopathic and nutritional compounds in the aqueous extract of needle litters of L olgensis and the metabolic substances in seed germination process of L olgensis and P. koraiensis.关键词
