- 摘要:
- 对阴香的8个种源共72个家系,即福建建瓯种源（W）13个家系、广东乐昌种源（L）7个家系、广东广州种源（H）3个家系、广东韶关种源（S）11个家系、赣县种源（G）11个家系、崇义种源（C）7个家系、信丰种源（X）10个家系、宁都种源（N）10个家系生长期为12个月的苗木生长性状，如苗高、地径、侧根条数、鲜重、干重等进行方差分析。结果表明：8个种源间有较大的变异，L种源表现最好而C种源最差，其中L种源苗高、地径、侧根条数、鲜重、干重均值分别为15.6 cm、4.25 mm、14条、3.180 g、1.087 g，而C种源只有8.2 cm、2.40 mm、11条、1.391 g、0.496 g；采用独立选择法，初选出10个苗期生长较快的家系。
- Abstract:
- By the variance analysis，the seedling stage growth characters mainly including the height，the diameter，the fresh weight，the dry weight and others of Cinnamomum burmannii which had grown for 12 months of 8 seedling sources，72 pedigrees.It was 13 pedigrees from Jian’ou，Fujian，7 pedigrees from Lechang,Guangdong,3 pedigrees from Guangzhou，11 pedigrees from Shaoguan，11 pedigrees from Ganxian，7 pedigrees from Chongyi，10 pedigrees from Xinfeng，and 10 pedigrees from Ningdu were studied.The results showed that there was big variation among the eight seedling sources.The L seedling source grew the best，while the C seedling source grew the worst.In L seedling source，the average number of the height，the diameter，the number of lateral roots，the fresh weight，the dry weight respectively was 15.6 cm，4.25 mm，14，3.180 g，1.087 g,while the average number of C seedling source was 8.2 cm，2.40 mm，11，1.391 g，0.496 g；Using the independent trial-and-error method，10 pedigrees growing quicker in the period of seedling stage were initially chosen.
