摘要：笔者对25个枫香种源种子千粒重、出苗率和1a生苗高生长进行分析比较,结果表明:不同种源在种子千粒重、播种出苗率和苗高生长方面均存在极显著差异,种子千粒重与出苗率极显著正相关,与苗高相关不显著,以苗高为选择指标,初步选择广西岑溪、云南富宁、广东翁源和海南霸王岭4个种源为优良种源,以2倍标准差法选择翁源09、富宁16等11个家系为优良家系。
1000-grain weight, seedling emergence rate and one-year-old seedling height of 25 provenances were analysed and compared by authors. The results showed there was a extremely significant difference with 1000-grain weight,seedling emergence rate and seedling height in different provenances. 1000-grain weight had a extremely significant positive correlation with seedling emergence rate but no significant correlation with seedling height. Four provenances of Chenxi of Guangxi, Funing of Yunnan, Wengyuan of Guang- dong, Bawangling of Hainan and eleven families were selected as the optimal provenances and families when select indicator was seedling height. Family selection method was double standard deviation.
