摘　　要：以溶液培养的方法,研究了不同浓度铝处理下日本落叶松、华北落叶松耐性差异,结果表明:日本落叶松、华北落叶松的耐铝性表现在根系与地上部分的干质量方面差异显著,铝胁迫抑制落叶松植株的生长,日本落叶松受到的影响明显小于华北落叶松;铝胁迫影响落叶松根系的吸收能力,日本落叶松在同等条件下受到铝的影响小于华北落叶松。Differences of tolerance for Larix kaempferi,Larix principis-rupprechtii under different concentrations of aluminum were studied by method of solution culture.Result shows that aluminum tolerance of Larix kaempferi and Larix principis-rupprechtii indicates that their leaf area,dry mass of root system and aboveground are significant.Aluminum stress inhibit growth of Larix gmelinii.Effect in Larix kaempferi are significantly smaller than that in Larix principis-rupprechtii.The absorption capacity of root system for Larix gmelinii were affected by aluminum stress.Larix kaempferi affected by aluminum less than that of Larix principis-rupprechtii under the same conditions.
