【摘要】 [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。更多还原

【Abstract】 [Objective] To study the differences in the tolerance of leguminous crops and cruciferous crops to microcystin (MC). [Method] 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 different 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.更多还原
