摘要 本文研究了不同种源胡枝子种子萌发及苗期生长的差异,结果表明,热水预处理对不同种源种子萌发有着显著的影响,以80℃热水处理的发芽率和发芽势最大,种源以尚志和林口的较大,敦化的较小。不同种源胡枝子在苗高、地径及生物量等方面均表现出明显的差异,三个种源以林口的生长指标最大,其次为尚志,而敦化的较小。 This paper studied the differences of seed germination and seedling growth of L.bicolor from different provenances.The results showed that hot water pretreatment had significant effects on seed germination of different provenances.The germination rate and germination potential of L.bicolor from different provenances were the highest when treated with hot water at 80℃.The provenances from Shangzhi and Linkou were larger than those from Dunhua.There were significant differences in seedling height,ground diameter and biomass from different provenances of L.bicolor.The growth indexes of the three provenances were the largest in the forest mouth,followed by Shangzhi,and the smaller in Dunhua.
