Abstract
The seedlings of maize(Yuyu22) were cultivated under two kinds of light conditions(natural light and about 50% shading light) and two nitrogen levels(260 kg/ha and 130 kg/ha).The values of stomatal aperture(SA),stomatal length(SL) and stomatal conductance(GS) of plants were all higher under natural light than under shading light,but not for the values of stomatal total length(STL) and stomatal frequency(SF).The values of SA,SF and GS of plants grown under high nitrogen supply were lower than those under low nitrogen supply for both light conditions,but the value of SL of plant grown under high nitrogen supply was higher than that under low nitrogen supply.The result of ANOVA showed that both light condition and nitrogen levels had significant effects on SA,SL,SF,STL and GS(P0.05或P0.01),and the ineraction effects of light condition ×nitrogen level on SA,SF,STL were also significant.It was found that SL was negatively correlated with SF,and SF was positively correlated with STL,while both SA and SF were positively correlated with GS.
