Abstract:: The pot experiments were carried out to investigate the effects of soil moisture on stalk germination,seedling morphological characteristics,biomass and the chlorophyll of Arundo donax.The results showed that seedling height,growth rate,leaf area,biomass and chlorophyll content of Arundo donax seedling decreased with the reduction of soil water content.The soil water content has significant effect on survival time of Arundo donax, and when it was less than or equal to 27.8% the Arundo donax died.The results also showed that when the soil water content was greater than or equal to 33.3%,stalks had axillary bud germination.Waterlogging in soil was not the best soil moisture condition for the growth of Arundo donax.The 38.9% of the soil water content was the best one for the growth of Arundo donax and its growth parameters of the seedling can achieve optimal under this condition.The soil water content ranging from 38.9% to 44.4% was the favorabl condition of Arundo donax growth and each growth parameters of the seedling may achieve the high level.
