Introduction: Nepeta Binaludensis Jamzad is a perennial and herbaceous species of the Laminasea family. Limited distribution, indiscriminate harvesting and destruction of natural habitats have put this plant in danger of extinction. In this research, the effect of different species of mycorrhiza fungi including: Glomus hoi, Glomus interaradis and Glomus mossea on the morphological and biochemical characteristics of N. binaludensis were investigated. Methods: In this experiment, 1Kg pots containing garden soil were considered as experimental units. Mycorrhiza species were added to three cm above the soil. The plants were grown for 20 weeks at 25° C and with a photoperiod of 16 / 8 hours of light/darkness. Results and discussion: The results showed that fungal species, especially G. intraradices, had considerably effect on most morphological characteristics. The highest content of total phenol, flavonoids and antioxidant capacity were recorded in plants inoculated with G. intraradices. Also, the accumulation of nutrients such as calcium, potassium, iron, magnesium and phosphorus in mycorrhizal plants was significantly higher than the control plants. The results of this study were confirmed that the use of mycorrhizal fungi as biological and environmentally friendly fertilizers can be a suitable alternative for chemical fertilizers.

Background and purpose: Ziziphora clinopodioides Lam. is a perennial plant from the Lamiaceae family, widely distributed in different regions of Iran. This research aimed to investigate the content of some phenolic derivatives (phenolic, flavonoid, flavone & flavonol, ortho-diphenol, and phenolic acid) during the vegetative growth of three populations of Z. clinopodioides belonging to North Khorasan province. Material and methods: For this purpose, the seeds collected from the regions ('Darkesh and Havar', 'Teymourtash', and 'Reine') were planted in pots and harvested at two vegetative growth periods (two and five months). After the sampling, the aerial part and root were separated and the mentioned phenolic derivatives were measured by spectrophotometric methods. Findings: The results showed that the content of phenolic derivatives is significantly affected by the type of population, plant part (aerial part and root), and age (growth stage). Therefore, the aerial part of Z. clinopodioides belonging to 'Darkesh and Havar' population, in the two-month stage, has more phenolic derivatives [total content of phenolics 11.91 mg GAE/g DW, flavonoids 13.55 mg CAT/g DW, flavone & flavonols 5.94 mg QUE/g DW, ortho-diphenols 2.95 mg GAE/g DW, and phenolic acids 2.44 mg CAE/g DW] than the five-month stage. Conclusion: In general, apart from the aerial part and the root, 'Darkesh and Haver' and 'Teymourtash' populations were reported as the selected population in terms of higher phenolic derivative contents in both vegetative growth stages. These results will help to select superior populations with higher content of metabolites and optimal use in food and pharmaceutical industries.
