To study the effects of foliar application of Zn element via nano- and chemical fertilizers on quantitative and qualitative characteristics of medicinal plant bitter apple (Citrullus colocynthis L.), an experiment was conducted in a randomized complete blocks design with three replications at the Agricultural Research Institute of Zabol University in 2019. Experimental treatments included foliar application of zinc nano-chelate at two concentrations (1000 and 2000 mg L-1), zinc sulfate at two concentrations (1000 and 2000 mg L-1), and control (water foliar application). The results showed that foliar application of Zn had a significant effect on the yield and number of fruits per plant, and the seed phenol content with the highest amount of these traits in zinc nano-chelate treatment at the concentration of 2000 mg L-1. Also, Zn foliar application increased the seed soluble carbohydrate content with the highest amount of this index in zinc nano-chelate treatment at the concentration of 1000 mg L-1. Zinc foliar application increased the concentration of Zn element in the leaves, while it did not affect the concentrations of N, P, and K elements. Generally, the application of zinc nano-chelate was more effective on the yield and number of fruits per plant, and seed phenol content than zinc sulfate.

Sarcocolla(Astragalus fasciculifolius Boiss.), belonging to Fabaceae family, is a medicinal plant distributed in the south of Sistan and Baluchestan province. Due to presence of compounds like saponins, flavonoids, and polysaccharides, it has an effective role in treating heart disease and cancer and eliminating chemotherapy and improving immunity. In this study, plant samples including eight A. fasciculifolius were collected from different habits in the province, and some phytochemical properties of root, leaves (total phenol, total flavonoid, and polysaccharide) and of flowers (total phenol, total flavonoid, and anthocyanin) were analyzed in the plant flower. The results of variance analysis showed a significant difference among different habitats (α>0.01). Phytochemical studies revealed significant amounts of phenolic compounds in the leaf with the highest rate recorded in Poshtkooh (14.62-32.55 mg GAE/g). In the root, the highest value was in Anjirok (20.39-53.84 mg GAE/g) and in the flower, the highest value was in BAirk (5.11-15.82 mg GAE/g), representing flavonoid compounds in the leaf in which the highest value was in Nahook (8.76-12.72 mg QE/g). Also, in root, the highest value was in Panjangosht (10 fingers) (0.25-1.03 mg QE/g). In the flower, the highest value was in Nahook (6.35-9.28 mg QE/g). In the polysaccharide compounds of the leaf, the highest value was in Anjirok (60.89-93.29 mg/g). In root, the highest values were in Pangangosht (94.33-209.38 mg/g) and anthocyanin of flower had the highest values in Pangangosht (36.34-77.58 mg/g). The results of this study represent the ability of different habitats of the province in producing valuable herbal compounds. Besides, because of its high levels of phenolic and polysaccharide compounds, this plant has a remarkable capability to be used in food and pharmaceutical industries.

Development and implementation of effective and useful programs for the rehabilitation, conservation and sustainable utilization of medicinal species is possible only by identifying plant and ecological characteristics. Astragalus fasciculifolius Bioss. belonging to the Fabaceae family, is a valuable medicinal species. This species plays an effective role in treatment of heart disease, inhibition of cancer cell growth, and eliminating the chemotherapy effects due to the presence of compounds such as saponins, flavonoids, and polysaccharides. In this study, the distribution map of this species was prepared using available resources, and then climatic characteristics, physical and chemical analysis of soil, different phenological stages, and associated plants in the region were recorded. The results of this study showed that this plant is distributed in the cities of Khash, Saravan, Soran and Mehrestan. According to the Demartonne method, the climate of this region is arid. The average annual precipitation, relative humidity, and an average temperature of these habitats are 52 mm, 20%, and 25°C, respectively. This species is distributed between approximately 1300 and 1500 m above sea level, on the slopes and mainly in the waterways, in the bed of seasonal rivers, and in all directions, especially the northern direction and the slope between 0 to 75%. The soil texture of habits is mainly sandy loam with the pH range of 6.73 to 8.28, EC range of 0.56 to 1.06 ds/m, and 30.64-50.62% lime. A. fasciculifolius is a drought tolerant species which is capable of growing under dry climatic conditions with an average annual rainfall of less than 30mm.

This study was aimed to investigate the effects of manganese stress and salicylic acid treatments at three different times on activities of antioxidant enzymes, proline, soluble sugars, photosynthetic pigments and essential oils of Mentha piperita L. The research was conducted in a greenhouse at the University of Zabol in 2012-13. A factorial experiment was performed in a randomized complete block design with three replications. Plant samples were harvested at three times in 1, 3 and 5 days after spraying with Mn stress (500µM) and salicylic acid (1mM). The results indicated that manganese stress significantly affected APX and proline content of peppermint leaves during all three times. The content of proline and soluble sugars significantly increased in three times compared to the control treatment under salicylic acid and manganese stress. On the other hand, the Mn stress did not significantly decrease the photosynthetic pigments. In addition, essential oils increased with manganese stress and salicylic acid. This increase was much under salicylic acid treatment. According to the obtained results, increased APX enzyme and proline content were the physiological responses of peppermint against oxidative stress. It was also observed that salicylic acid acted as a powerful growth regulator and caused modification in manganese stress response in Mentha piperita.
