十字花科与豆科作物对微囊藻毒素耐受性差异的比较

摘要

[Objective] To study the differences in the tolerance of leguminous crops and cruciferous crops to microcystin （MC）. [Methed] The cruciferous typical crops oilseed rapes, pakchois, cabbages and leguminous typical crops soybeans, peas and broad beans were selected as the materials to test the effects of MC of differ- ent concentrations on the germination, growth and development of leguminous crops and cruciferous crops. The measurement indicators included germination rate, plant height, chlorophyll, etc. [Result] The MC had great effects on the oilseed rape and pakchois of cruciferous crops, and smaller effects on cabbage, while the leguminous crops were generally not affected. [Conclusion] Leguminous crops are more tolerant to MC than cruciferous crops and more preferential in MC polluted regions.%[目的】研究十字花科与豆科作物对微囊藻毒素（MC）耐受性的差异。[方法]以十字花科作物典型作物油菜、小白菜、甘蓝与豆科典型作物黄豆、豌豆、蚕豆为材料，检测它们在不同浓度MC暴露条件下的生长发育情况，检测指标包括发芽率、株高、叶绿素等。[结果]十字花科作物中油菜与小白菜受MC影响较大，甘蓝受影响较小，而豆科作物普遍受影不大。【结论]豆科作物比十字花科作物对MC耐受性更强，在受微囊藻毒素污染地区可以优先种植豆科作物。
