Abstract
Flue-cured tobacco seedlings were grown in the culture boxes floating on nutrient solution and inoculated without and with Glomus intraradices 193(BEG-193)and Glomuse etunicatum 168 and HEB07A(BEG-168 and BGC-HEB07A),respectively.Thereafter,the seedlings were used to investigate the growth,nutrition and drought resistance.The results indicated the sensitivity of the seedlings to water stress and the decrease in biomass by 27.24% in light drought compared with normal water supply.The seedling biomasses inoculated with BEG-193 and BGC-HEB07A were higher than that without inoculation,while there was no difference between BEG-168 inoculation and non-inoculation.Fungal inoculation increased generally in the concentration and absorption of nitrogen,phosphorus and potassium.In addition,malondialdehyde increased by 1.71(light drought)and 5.56 folds(serious drought),respectively.However,chlorophyll and root activity were reduced only in serious drought condition.The results suggested easy damage of membrane lipoids under water stress.It was observed the lower malondialdehyde but the higher chlorophyll and root activity following fungal inoculation compared with non inocculation.Therefore,fungal inoculation might reduce the damages of membrane lipoids and keep photosynthesis and root activity.It is necessary to point out the influence of fungal inoculation on growth,nutrition,malondialdehyde,chlorophyll and root activity varied in fungal strains and drought degrees.Suitable fungal stains should be selected in tobacco seedling cultivation.
