Evaluation Of The Effects Of Flooding On Three Varieties Of Rice

        Flooding has been described as one of the most important environmental factors determining the distribution of salt marsh plants. We studied the impact of five water levels on the germination and establishment of the invasive cord-grass spartina deniflora. Plant house experiment was carried out to determine the effects of time and depth of flooding on the survival and growth of rice. Data showed that time and depth of flooding had significant effects on the survival and growth of rice.         The germination rate was decrease gradually with depth. There was no seedling emergence from…
