Abstract:

Spraying the selenium to the leaf surface is the most important way to get the tobacco which is rich in selenium; this experiment has studied the effect of selenium to the leaf tobaccos in the selenium content and some physiological targets influences in the growth process by two kinds of selenium in the early time. The result showed that the GSH-Px Activity of tobacco leaves kept relatively high activity, The MDA is lower than the comparison, the selenium content in the leaf tobacco enhances in evidence, the effect of compound selenium is higher than the Na2SeO3 obviously, and it delayed the leaf tobacco to be senile.
