- Lemna is a genus of free-floating aquatic plants from the duckweed family. These rapidly growing plants have found uses as a model system for studies in community ecology, basic plant biology, in ecotoxicology, in production of biopharmaceuticals, and as a source of animal feeds for agriculture and aquaculture. Zinc is a one of micronutrients essential for plant growth and development, in addition, Zinc is heavy metals and too mach Zinc can cause a toxicity in most plants currently, environmental pollution, especially pollution from heavy metals due to industrial activities indiscriminate use of chemical fertilizers cause irreparable damage in the plants. In this study examined the effect of different concentration of Zn [control (zero), 0.003, 0.005, 0.01, 0.012, 0.015and 0.018 g] on chlorophyll, soluble sugars and proline in duckweed (Lemna minor). The results showed that high Zn concentration decrease of photosynthetic pigments such as chlorophyll a and chlorophyll b, however, soluble sugars and proline increased. These compounds are used in various stress for osmotic adjustment, preserve the enzymes and membranes in plant cells.
