摘要:
外来植物入侵已成为全球性环境问题,而全球的环境变化如气候变暖、氮沉降及盐渍化等因素又反过来会影响入侵植物的形态属性、入侵性等。以外来植物南美蟛蜞菊和本地蟛蜞菊为研究对象,采用同质园试验研究比较了南美蟛蜞菊和本地蟛蜞菊对模拟盐胁迫的生理生态响应,初步探讨了南美蟛蜞菊对盐环境的适应性。结果表明,南美蟛蜞菊呈现出盐胁迫抑制生长的规律,而本地蟛蜞菊呈现出低盐胁迫(0.1 mol/L)促进生长,中高盐胁迫(0.2、0.3 mol/L)抑制生长的规律,对植物生长的抑制作用主要表现为总生物量、相对株高、茎节数以及根长的减少。其中低盐胁迫下2种植物的叶片数均有所增加。随着盐浓度的升高,2种植物叶片中的脯氨酸含量、丙二醛含量、过氧化物酶和过氧化氢酶活性都呈现先增加后下降的趋势。这些结果可为今后南美蟛蜞菊适生区的预测及其入侵防控提供理论依据。
