Abstract:
Pepper seedling was used as test material,the soil moisture in 40%-50% was controled by using the weighing method for potted and sprayed different concentrations of vitamin C on the leaf of pepper.The concentrations were 0,20,40,60,80,100,120 mg?L-1,respectively.Morphological and physiological indexes of pepper root were measured and explored effects of drought stress and vitamin C on growth of pepper seedling root.The results showed that,a certain concentration of vitamin C could alleviate the effects of drought stress on root growth of pepper and improve the absorption of pepper roots and water retention ability.Meanwhile,low concentrations of vitamin C promoted the growth of pepper roots while high concentrations inhibited.The effect was the most significant when the concentration was 40 mg?L-1.Root length increased by 0.273%.Root water content and membrane permeability decrease by 2.58% and 11.46%,respectively.Root activity,CAT activity,Pro content and POD activity increased 1.33%,11.1%,13.61% and 12 times than that of control,respectively.
