Abstract:: Stolon of Cynodon dactylon was influenced by soil water content on germination and seedling growth in the process of biological and ecological indexes by pot culture experiment using six soil samples with water content of C₀ (5%), C₁ (10%), C₂ (20%), C₃ (25%), C₄ (30%) and C₅ (35%). The results showed that: (1) with the increase of soil moisture content, the germination rate, seedling height, leaf number, leaf length, leaf chlorophyll and biomass per plant of Cynodon dactylon Stolons were increased firstly and then decreased; (2) with the change of soil moisture content, its biological and ecological characteristics (seedling height, leaf number, leaf length, biomass per plant) value present significant or extremely significant correlation; (3) through the analysis of the response of Cynodon dactylon stolons to different soil moisture by Gauss model, we could predict the germination and seedling of optimum soil moisture ecological amplitude value and limit ecological amplitude value was 14.78%, 30.15% and 5.65%, 38.26%, respectively. Effects of soil moisture content on Germination seedling biomass and average length of blade of Cynodon dactylon stolons were the most sensitive.
