Effect of salt stress and AM fungi on the growth performance of pea plant
Keywords:
AM fungi, salt stress, Acaulospora appendicula, Acaulospora gerdemannii, control and mycorrhizal plantsAbstract
The study was conducted to determine the effect of arbuscular mycorrhizal (AM) fungi inoculation on growth of pea grown under salt stressed pot culture conditions. The pots were placed under shade net and watered with normal water for 1 month at the interval of 2 or 3 days depending on the requirement. For each treatment, ten replicates were maintained. The various AM fungi used for pot culture were Acaulospora appendicula, Acaulospora gerdemannii, Glomus fasciculatum, Glomus intraradices and Scutellospora heterogama. The fresh and dry weight of root and shoot of both control and experimental plants decreased with the increase in salt stress. The fresh and dry weight of the root and shoot of mycorrhizal plants were comparatively more than those of control plants. The number of leaves was decreased with the increase in salt concentration. The number of leaves produced in mycorrhizal plants was more as compared to control plants during salt stress.
