摘  要:
对杉木种源所设 5个种源基因库以及四川省珙县洛表、民胜及邛崃所设种源试验区的 8个种源试验调查材料 ,用随机效应检查方法检验同一地区不同种源对断面积生长模型参数的影响。结果证明了“同一地区不同种源的断面积模型参数相同”这一结论可靠。

摘  要:
The impact of Chinese fir (Cunninghamia lanceolata) provenances planted in the same region on their basal area growth models was verified by the method of random effects test with the data from eight forest farms, Jigongshan, Hongya, Dagangshan, Liuzhou, Liufengshan, Gongxianluobiao, Gongxianminsheng and Qionglai. Results show that parameters of basal area growth models among Chinese fir provenances planted in the same region are of no significant difference.
