旱冬瓜种源/家系苗期生长指标的研究

Study on Growth Indicators of Alnus nepalensis Provenance/Family in Seedling Period

对15个种源99个旱冬瓜家系苗木的苗高和地径生长量进行了测定与分析,结果表明,种源及家系间苗木的苗高和地径生长差异显著,其中以瑞丽种源最好,其次为孟连、西盟、陇川、潞西的种源,表现最差的是镇沅种源;家系间苗高生长量表现最好的是瑞丽的62号家系,地径生长量表现最好的是瑞丽的49号家系;苗期综合表现较好的家系有22个,分别为49、50、51、52、53、55、59、61、62、72、77、78、81、85、88、94、120、122、123、127、128、129号家系。

According to 15 provenances 99 Alnus nepalensis family seedling height and diameter growth measurement and analysis,the results showed that seed source and families seedling height and diameter growth represent significantly difference,among which,the best provenance is Ruili,followed Menglian,Ximeng,Longchuan,Luxi provenance,the worst is Zhenyuan provenance; families of high growth performance of thinning is the best Ruili No. 62 pedigree,diameter growth is the best family Ruili No. 49; there are 22 families which is better overall performance at seedling stage,they are 49,50,51,52,53,55,59,61,62,72,77,78,81,85,88,94,120,122,123,127,128,129.
