Drought Tolerance Effect of Mycorrhıza ın Plantago
Lanceolata L. (Narrowleaf Plantaın) Plants This study was conducted to determine the effects of Rhizophagus intraradices applications on the plant growth changes, plant nutrition and stress tolerance in Narrowleaf Plantain under the drought stress.
In this research, three different drought levels (low, medium, high) were applied with mycorrhizal and without mycorrhizal conditions according to the randomized design with five replications. Germinated seeds were first sown into the plastic trays and 3 weeks later they were transfered into the 3 lt plastic pots. When the plants were approximately three months old, drought stress application was started.
In our results, we have observed that mycorrhiza applications had positive effects on the root and leaf dry weights, total dry weight, leaf lenght and root/shoot ratio, but had no effects on the leaf area. Drought stress applications had also effects on the amount of vesicles, number of leaf and leaf fresh weight but no effects on the percentage of fungal colonization of the roots and amount of arbuscules. In conclusion, by mycorrhizal applications, it might be possible to decrease the negative effects of drought stress on plant growth and plant nutrition in Plantago lanceolata L. considerably and plants may become more tolerant against drought stress.
