Abstract:
Since many times the cultivation of medicinal and aromatic herbs has been a special place in Iran's agricultural systems. On the other hand, ecological farming and low input systems can promote sustainable agriculture and environmental health. The aim of this study was to evaluate performance of several species mycorrhizal fungi and Trichoderma in the rhizosphere on some of the crop characteristics of dill plant, in greenhouse conditions using. For this purpose, a factorial experiment was conducted in a randomized complete block design with three replications in the greenhouse of Horticulture Department, faculty of Agriculture, University of Tabriz. For instance the roots of two Anethum graveolens (Dill) species i.e. Tabriz local A. graveolens and Long Island of Mammoth, were treated with the inoculums provided of Trichoderma isolates (Trichoderma harzianum Na-1ac and T. longibrachiatum BZ4-4) and two species of Mycorrhiza fungus (Glomus intraradices and G. versiforme). The results of this study showed that the significant incrementing effect of fungi on shoot fresh weight, shoot dry weight, root fresh weight, root dry weight, chlorophyll index and colonization. Also, the effects of cultivars and fungi on traits such as plant height, number of umbelle in umbelete, grain yield in each plant and number of branches in each plant were significant. Interaction of cultivar and fungus were also significant on the number of branches in each plant and grain yield in each plant and increased them. Also, the results results indicated that the percentage of colonization in G.intraradices was significantly higher than in G. versiforme. The investigation of the endophytic state of Trichoderma and the progress of the fungus in various tissues of the plant were detected only in the plant root portion of the. Also the comparing result between two genera showed significant difference in most traits and Trichoderma was better than Glomus in most of the measured traits. Finally, our results indicated that the use of Trichoderma and mycorrhizal fungus in comparison with the control can be an effective tool for increasing of the growth characters and the use of Trichoderma more effectively presence a natural method to improve the growth of the plant.
