Effect of Arbuscular Mycorrhiza Fungi on Drought Resistance in Tea Plant(Camellia sinensis)
To study effect of Arhuscular mycorrhizal fungi(AMF) on the drought resistance in tea plant,pot experiments with AMF treatments were conducted under the condition of drought stress:inoculating with Glomus versi forme,Glomus intrardices or Glomus mosseae.The results indicated that inoculation with AMF could significantly increase the biomass of tea plant,increase the mass fraction of proline and soluble protein,enhance activities of protective enzymes,such as superoxide dismutase(SOD),peroxidase(POD) and catalase(CAT),and increased the mass fraction of glutathione(GSH),and decrease the mass fraction of O2+-and H2O2,decreased malondialdehyde(MDA) molality and electrolyte leakage under water stress.The optimum treatment was inoculated with Glomus versiforme.The results showed that under the drought condition,inoculating AMF could improve osmotic regulation and antioxidation,scavenging reactive oxygen species(ROS) and membrane stability,alleviate the harmfulness of water stress,promot tea plant growth and enhance drought resistance of tea plant.
