【 摘 要 】

One of the main limiting factors in crop production in different regions of Iran is water deficit stress. Mycorrhiza and vermicompost fertilizer may be help plants to uptake more water. Therefore, a greenhouse experiment was carried out in factorial design that was carried out to evaluate the effect of Mycorrhiza, vermicompost fertilizer and water deficit stress on some physiological traits of sweet basil ( Ocimum basilicumL.). Factors included Mycorrhiza (inoculation and non-inoculation), Vermicompost fertilizer (0, 30, 50, and 70 percentage of pod volume), and water deficit stress factor included irrigating up to 60% of F.C as water deficit stress treatment, up to 75% of F.C as mild water deficit stress treatment and up to 90% of F.C as well irrigated treatment. The results showed that sugars and proline increased with increasing water deficit stress, while higher vermicompost consumption decreased the severity of the increase. Merging vermicompost, and mycorrhiza, had a synergistic effect on the catalase enzyme and chlorophyl a+b. Significant negative and positive relationships were found between shoot dry weight and proline with water deficit stress. In addition, basil plant physiological responses to drought stress showed that this stress-sensitive plants, tried to adjust to stress, through osmotic adjustment and increasing antioxidant activity. The results totally showed that merging mycorrhizal inoculation and vermicompost mitigate the effects of drought stress in Basil. .
