The Effects on Physiology and Bio-chemical Characteristics of Soybean by Cultured in the Selenium and Vermiculite Medium
Abstract：In this paper vermiculite and the different concentration of selenium is used to develop soybean, researching view form, biology form, physiology form of the soybean. The results showed that, it can promote soybean plant growth with modest concentration selenium into vermiculite medium, but extra selenium concentration would repress the growth of soybean; the modest concentration selenium into vermiculite medium can raise the level of the contents of dissolubility protein and sugar compared with the matched control, so it can strengthen the resistance ability of soybean; when the selenium concentration higer than 5μg·mL^-1 , the contents of proline raised and the resistance ability of soybean increased. But when the supplement of the selenium concentration is 0.1 - 5μg·mL^-1, the MDA contents is smaller than the matched control, when it achieved 10 μg·mL^-1 ,the MDA contents is higer than the matched controls and lower level, consequently, the low level of selenium （the supplement of selenium concentration is smaller than 10μg·mL^-1 ） can decreace the outcome of MDA and have anti-oxidation effect on the soybean. The chlorophyll contents is higher than matched control when the selenium concentration is lower than 10 μg·mL^-1. It explains that modest concentration selenium can promote photosynthesis of soybean, then it promotes soybean plant growth.
