Abstract
Effects of DA-6,indolebutyric acid,naphthylacetic acid and ethylene on physiological functions and yield were studied with a plot experiment in the high yield maize.The results showed that DA-6,used alone at the dosage of 4.5 gram active ingredient per hectare at the 7～8 leaf stage of maize,or it combined with the indolebutyric acid and the naphthylacetic acid(its mass ratio is 1:1),sprayed at the dosage of 4.5 gram active ingredient per hectare at the 4～5 leaf stage of maize,both significantly promoted the stem diameter,the root activities,chlorophyll contents,nitrate reductase activities and glutamine synthetase activities in maize functional leaves,which were better than others and had the highest yield.The root activities were increased by 16.5% and 6.7% compared with that in CK(the control treatment) at large bell period and flowering period by foliage spray of the indolebutyric acid and the naphthylacetic acid at the 4～5 leaf stage,and it became lower than that in CK at filling stage and wax ripeness stage.Ethylene reduced plant height,ear height and increased the stem diameter.Therefore,the capability to resist lodge of maize straw was enhanced to a certain extent.However,its production was less than CK.
