Growth stability of Betula platyphylla provenances from three sites
摘要
Abstract
Multi-site forestation testing is a key step in the evaluation of stability analysis and growth traits of tested provenance. Tree height (H), diameter at breast height (DBH) and volume (V) of 18 Betula platyphylla provenances, which have been planted for 17 years in Maoershan, Caohekou and Jinhe, were measured and analyzed. The results showed that there were significant differences (P<0. 01) in the H, DBH, and V among different sites and provenances,and also significant differences in site í provenance interaction. The result of provenance preservation rate analysis showed that the average preservation rate of 18 B. platyphylla provenances ranged from 4. 76% to 76. 55%. Among them, the average preservation rate of Dongfanghong, Liangshui, Changbai and Wuyiling provenances was higher and that of northwest region such as Liupanshan, Xining and Tianshui was lower. Height stability of tested provenances was assessed with AMMI model. The result indicated that Liangshui, Xiaobeihu, Huinan, Dongfanghong, Lushuihe, Huanren and Tianshui belonged to high-yield and stable provenances;Wuyiling, Maoershan, Wangqing, Caohekou, Qingyuan and Moerdaoga belonged to high-yield but instable provenances;Zhaosu, Changbai and Xining belonged to low-yield and stable provenances; Chaoer and Liupanshan belonged to low-yield and instable provenances. These results provide a theoretical basis for the selection and also a reference for the application and spread of superior provenances.关键词
