【摘要】 通过对 2年生 3个四倍体刺槐无性系和 1个普通无性系的生物量调查和对比 ,发现四倍体无性系对西北环境的适应性较好 ,其生物量均超过了当地普通刺槐。这表明 ,其作为再生型木本饲料在生态条件较差的西北地区有一定的开发潜力。由无性系在不同立地条件下比较发现 ,土壤因子对刺槐生长有较大影响 ,其中较为显著的是水分供给条件更多还原

【Abstract】 Biomass of three tetraploid Robinia pseudoacacia L.clones and one local diploid clone is investigated in the paper. The result indicates that the tetraploid clones are adaptive to the local environments in experimental sites of North-West China. The biomass of the tetraploid clones exceeds that of the local diploid clone, which shows that it is potential to develop as regenerated woody forage in poor natural ecological condition of north west regions. The growth of Robinia pseudoacacia L.clones in different sites is related to soil characters and nutrients, of which the most important effect is water supplied in soil.更多还原
