Plant phenotypic traits such as plant height, greenness, vegetation index, plant leaf area and root length are the result of interaction between the plant's intrinsic gene and the external environment. The plant phenotype is very sensitive to environmental change, and the plant growth rule and the plant phenotype character under different environmental conditions may have larger difference. Analyzing the phenotype difference of plants under different environmental conditions is helpful for scientific researchers to further analyze the interaction mechanism between the plant genotype and the environment.
