The aim of this research is to investigate the habitat and phenological conditions of Helichrysum leucocephalum Boiss. in 5 natural habitats of Fars and Yazd provinces. After the identification of the habitat, 4 transects of 100 meters were randomly placed in the representative area, and 10 plots of one square meter were placed along each transect. Inside each plot, the percentage of vegetation, density and abundance of the desired species were recorded. Soil samples were taken from zero to 30 and 30 to 60 cm from plots of each transect. The physical and chemical factors of the soil were measured using conventional methods in the soil science laboratory. The topographic characteristics of each habitat were recorded using a GPS device and the height, slope and direction factors were measured. To record the phenological stages of the species in each habitat, 5 bases were selected and the vital and phenological stages of the species were recorded every 15 days. The results showed that the highest and lowest percentages of H. leucocephalum cover were 40 and 10% respectively in Damgahan-Mehriz habitats of Yazd and Dareh-Morghi of Estehban. The highest density (1 individual per square meter) and the lowest density (0.1 individual per square meter) are in Niriz and Dareh-Morghi habitats, respectively. The highest ferequence in Abadeh- Tashk habitat is 55% and the lowest ferequence is in Bonab-Arsanjan habitat with 25%.Determining the habitat conditions of medicinal species for domestication and modification and development of vegetation in rangelands is a necessary.

The various saffron corm planters that have been built in the country so far have been used to cultivate saffron corms for several years and corms are planted in rows with densities of 7 to 10 tons per hectare. In this research, a device was designed and built that has the capability of strip and corms dense cultivation (up to 20 tons per hectare). The width of each planting strip is 1100 mm, and for the passage of tractor wheels (narrow wheel), 40 cm of uncultivated space was considered in the distance between the planting strips. In order to evaluation of corm planter, the effects of planting speed at two levels (3 and 5 km/h) and plant density at three levels (10, 15 and 20 tons per hectare) on performance, percentage of injury’s corms and distribution uniformity of corms were investigated. The results showed that by increasing the planting speed from 3 to 5 km/h, the damage to the corms increased by 11.4%.

The purpose of the present research is to determine the conservation status of endemic and rare medicinal species of the Asteraceae family in wide province of Razavi Khorasan. These medicinal species: Achillea pachycephala، Artemisia khorassanica، Cousinia verbascifolia، Echinops heteromorphus، Echinops leiopoliceraoides، Echinops khorassanicus، Echinops procerus، Echinops sabzevarensis and Tanacetum khorassanicum were studied and investigated according to the International Union for Conservation of Nature.

The regeneration status and habitat quality were observed. The results showed that the conservation status of all medicinal species was placed in CR/ Critically Endangered, based on the presence criteria. The process of destruction of most habitats was high, and road construction followed by agriculture, construction, and mining were estimated as the most important habitat destruction factors.

In this regard, the present study was conducted to investigate the morphophysiological characteristics and element concentrations of purple coneflower (Echinacea purpurea L.) under salinity stress at three levels (0, 50, and 100 mM) and selenium dioxide nanoparticles (no foliar application (control), 50 and 100 mg/L); in a factorial design based on a completely randomized design with three replications. The results showed that 100 mM NaCl salinity stress significantly reduced plant morphological traits (plant height, shoot dry weight, and photosynthetic pigments). The use of selenium nanoparticles reduced the effect of salinity stress in purple coneflower. The highest amount of phenol and total flavonoids was observed in the 50 mM treatment (mild salinity stress). The results showed that purple coneflower is sensitive to salinity stress and the reduction in yield was quite evident. Therefore, according to the results of this study, foliar spraying of 100 mg of selenium dioxide nanoparticles can be recommended to reduce the negative effects of salt stress in purple coneflower plants.Salinity is one of the most destructive stresses that reduce the production and yield of agricultural products in all regions of the country.

And the highest inhibition rate of DPPH free radicals was observed with oven treatments with temperatures of 50, 70 and 90, microwave with powers of 180 and 900 and shade. <br /><br />The highest amount of shrinkage was related to microwave treatment with powers of 180 and 900 watts, the highest amount of water reabsorption and the lowest amount of bacterial, fungal and total microbial contamination was related to microwave treatment with power of 900 watts. In the infrared lamp and heat lamp treatment, the amount of all these traits increased significantly, and the amount of tissue shrinkage and contamination was lower.Berberis integerrima is one of the most important medicinal plant in South Khorasan. This study was conducted to evaluate the effect of different drying methods on biochemical and morphological traits of barberry fruit based on a completely randomized design with 8 treatments including oven (at temperatures of 50, 70 and 90°C), microwave (at powers of 180 and 900 watts), heat lamp, infrared lamp and shade in 3 replications .<br /><br />The results showed that the effects of different drying methods on soluble sugar, proline, pH, anthocyanin, antioxidant, color, shrinkage, resorption, bacterial and fungal contamination, and total microbial load were significant at the 1% level, but they did not have a significant effect on polyphenol and flavonoid traits.The results showed the highest amount of soluble sugar (about 232.5 mg/g dry weight) and proline (about 8.4 mg/g dry weight) in infrared, shade, microwave with 180 watt power and heat lamp treatments. And the highest inhibition rate of DPPH free radicals was observed with oven treatments with temperatures of 50, 70 and 90, microwave with powers of 180 and 900 and shade. <br /><br />The highest amount of shrinkage was related to microwave treatment with powers of 180 and 900 watts, the highest amount of water reabsorption and the lowest amount of bacterial, fungal and total microbial contamination was related to microwave treatment with power of 900 watts. In the infrared lamp and heat lamp treatment, the amount of all these traits increased significantly, and the amount of tissue shrinkage and contamination was lower.https://mpt.areeo.ac.ir/article_134016_38e6b33f67ec817e6e95908d3ce68e4f.pdf
