Vicia faba seedings were cultured in flowerpots with equal size and same soil.Then the foliage was sprayed with 1.5 % Methanol,10 mmol/L Vc and water.Five days later,the total chlorophyll content,the content of chla and chlb,the ratio of chla/b and the activities of peroxidiase(POD)and super oxide dimutase(SOD)in growing leaf were measured.The result showed that the vicia faba leaf sprayed with methanol and Vc had the highest content of total chlorophyll and the highest ratio of chla/b among treatments,the ...
