摘要
对江西崇义、石城、兴国和于都4个光皮树种源苗期生长性状进行研究,结果表明,4个种源种子播种品质差异较大,但苗期高生长规律基本一致,生长高峰期为6月中旬至10月初;光皮树种源内和种源间均存在较为丰富的变异,具有较大选择潜力;苗期生长性状表现较优的为于都种源。
The growth characters in the seedling stage of Cornus silsoniana Wanager provenances of Chongyi,Shicheng,Xingguo and Yudu were studied.The results showed that the difference in the seed quality was large,but the height growth rules in the seeding stage were accordant.The growth fastigium was between June midst and October inception.There was abundant variation between the four Cornus silsoniana Wanager provenances or within one of these provenances,and the choice potential was remarkable.The Yudu provenance was better than the others in the growth characters in the seedling stage.
