Abstract
Cotton plants were cultured in flowerpot for the investigation of the effect of available silicon in soil on cotton seed germination and nutritive metabolism of seedling. The result showed that available silicon in soil had no remarkable effect on cotton seed germination rate,but the effect on seedling nutrition metabolism was significant. When the content of available silicon in soil was between 55.1 and 247.0 mg·kg -1 , with the increase of available silicon in soil, the photosynthesis rate of cotton seedlings during seedlings growth increased. The transpiration rate decreased, while water utilization efficiency and leaf water content increased. The content of P, Zn and B in cotton seedlings increased, but the content of N, K, Mn, Ca and Mg in cotton seedlings were decreased,and the content of Cu and Mo change were not obvious. From the results mentioned above, it can be shown that silicon assimilated improved nutrition metabolism of cotton seedlings. As a result, seedlings growth rate were advanced.
