摘要

Invasive plants are characterized by rapid growth and multiplication; absence of natural predators; high adaptability; long-lived seed production; and competition for resources. Eichhornia crassipes; Acacia spp.; Carpobrotus edulis; Dichrostachys cinerea; Ulex europaeus; Ailanthus altissima; Azolla spp.; Buddleja davidii; Cortaderia selloana; and Caulerpa taxifolia are specially problematic in tropical countries. Abiotic factors like temperature, light, moisture, soil pH, and nutrient availability play a crucial role in the spread and success of invasive plants. Soil salinization is a process where soluble salts accumulate in the soil, negatively affecting vegetation. In tropical countries, this phenomenon can significantly impact invasive plants. The main invasive aquatic plants found in Ciego de Ávila, Cuba, are water hyacinth (Eichhornia crassipes) and water lettuce (Pistia stratiotes). This mini-review summarizes the effects of salinity, under controlled experimental conditions, on the levels of chlorophylls (a, b), carotenoids, soluble phenolics, cell wall-linked phenolics, malondialdehyde and other aldehydes.
