Abstract: In this paper the effects of coating water absorbent to seeds on their germination and the effects of soaking roots of seedling fruit trees in water absorbent on their survival rate were studied.The results shows that the seeds of soybean and mung bean whose protein content are high have higher germination rate when coated with water absorbent compared with uncoated seeds.But there was no effect founded with corn and wheat seeds which have a high content of starch.The results also indicate that when roots of fruit seedlings soaked in a high concentration water absorbent the survival rate was decreased,but in low concentration the rate was increased.
