| Abstract: |
| Piriformospora indica fungi were inoculated on seedling roots of peanut to investigate their effects on drought tolerance. There were 3 treatments including inoculation+drought, no inoculation+drought, and no inoculation+no drought (CK) in the experiment. The results showed that the length of taproots, fresh weight of roots, dry weight of roots, fresh weight of stems, dry weight of stems, fresh weight of leaves, dry weight of leaves and chlorophyll content(SPAD) under inoculation+drought treatment were 14.96 cm, 0.64 g, 0.08 g, 1.48 g, 0.20 g, 1.61 g, 0.29 g and 42.63 respectively, and significantly increased by 26.8%, 25.50%, 60%, 15.63%, 17.65%, 15.59%, 26.09% and 7.43% respectively, compared with no inoculation+drought treatment. Meanwhile, there was no significant difference between inoculation+drought treatment and CK in the agronomic traits of length of taproots, fresh weight of roots, dry weight of roots, dry weight of stems, dry weight of leaves and chlorophyll content (SPAD). These results suggested that Piriformospora indica fungi could maintain normal growth of peanut in drought stress conditions, and improve drought tolerance of peanut plants. |
