通过对Ti、Be、111、Ta、109、Me、Br、La、50、Por、36杨等11个杨树新品种引进栽培一年来的试验观测,进行方差分析和多重比较,结果表明:Por、36杨生长量超过了107杨、108杨,而且也大大超过了其他无性系,且干形通直,可以优先推广。Be、111生长量与107杨、108杨相当,这两个无性系也是优良无性系。Ta、Me、Br、La等4个无性系的生长量都远远低于107杨、108杨,暂作淘汰品种,留作后续观察。
A total of 11 poplar cultivars such as Ti, Be, 111, Ta, 109, Me, Br, La, 50, Por and 36 poplars were tested and analyzed by ANOVA and multiple comparisons. Yang grows more than 107 Yang, 108 Yang, but also greatly exceeded the other clones, and stem straight, you can give priority to promotion. The growth of Be, 111 is comparable with that of 107 Yang and 108 Yang, and these two clones are also excellent clones. The growth of four clones, Ta, Me, Br and La, was much lower than that of 107 Yang and 108 Yang, which were temporarily eliminated and reserved for follow-up observation.
