چکیده
  Researchers have found that a user’s perception of the campus environment is related to quality life and academic accomplishment. In this study, we have analyzed the perceptions of more than 600 users at the Ferdowsi University of Mashhad to evaluate the level of green space use and to understand user preferences from aesthetics and safety aspects. The results show that for most of the respondents (more than 80%), the use of green space was nearly 40%. The respondents’ aesthetics and safety preferences were more than moderate (65%) and nearly high (70%) respectively. A high correlation ...  بیشتر

چکیده
  To evaluate the effect of water-deficit stress on the yield, antioxidant activity, and physiological traits of four Iranian melon genotypes (“Khatooni,” “Suski-Sabz,” “Zarde-Tabriz,” and “Shiari”), an experiment was conducted. The irrigation levels were: (1) control (100%ETc); (2) deficit irrigation 66% (66%ETc); and (3) deficit irrigation 33% (33%ETc). The results showed that the yield and relative water content (RWC) significantly decreased in response to an increase in water-deficit stress. The highest yield reduction (60.7%) was measured in Khatooni ...  بیشتر

http://dx.doi.org/10.22059/ijhs.2017.63644

چکیده
  The present study was conducted to evaluate the effect of expanded clay (Leca) and Styrofoam on the physical characteristics of growing media and their relationship with the growth of Spathiphyllum wallisii. The experiment was laid out in a complete randomized design (CRD) with 9 treatments and 3 replications. Cocopeat and peat moss combined with different proportions of inorganic materials Leca and Styrofoam were used as conventional media for the growth control. Growing indices of plants consisting of the number of leaves, shoot length, the fresh and dry weight of shoot and fresh and dry weight ...  بیشتر

دوره 48، ویژه نامه ، مهر 1396، صفحه 35-43

http://dx.doi.org/10.22059/ijhs.2017.202867.970

چکیده
  The present study was carried out during 2007, 2008 and 2009 on 6 olive cultivars to investigate the process of oil and dry matter accumulation in response to warm and dry conditions in Dallaho Olive Research Station of SarpoleZehab, Kermanshah province, Iran. Results showed that oil begins to accumulate in the fruit from July, increases gradually through August and reaches its maximum as the fruit becomes completely black in November. Patterns of oil accumulation over the period of the study varied between cultivars. Dry matter acquisition was continuous and increased with a slow slope in all ...  بیشتر

چکیده
  Saffron (Crocus sativus L.) is one of the most important economical crops in Iran. The present study was conducted to evaluate the morphological characteristics and yield of saffron corms in six regions of Talesh city, Guilin province (Iran) with different altitudes. The studied regions were considered as treatments and the obtained data were analyzed based on a nested design. The results showed significant difference among the cultivation areas in terms of number, diameter and dry weight of corm. The areas withaltitudesof ~1250 and ~1400 m produced the maximum number of corm per plant (7.64 and ...  بیشتر

دوره 48، ویژه نامه ، مهر 1396، صفحه 53-62

http://dx.doi.org/10.22059/ijhs.2017.63909

چکیده
  Primary bud necrosis (PBN) of grapevine, which is a physiological disorder, seriously decreases the fruit yield of vineyards. This research was carried out to determine the effects of mineral deprivation on increasing the incidence of PBN in ‘Askari’ table grapes in Sisakht region of Southwest of Iran. For this purpose, the changes of mineral elements in leaves and PBN percentage were estimated on both fruiting and de-fruited ‘Askari’ vines. The experiment followed a factorial experiment in a randomized completely block design consisting of 10 × 2 (10 sampling dates ...  بیشتر

Naser Ghaderi؛ Bakhtiar Shokri؛ Taimoor Javadi

دوره 48، ویژه نامه ، مهر 1396، صفحه 63-78

http://dx.doi.org/10.22059/ijhs.2017.207423.1017

چکیده
  Application of natural compounds such as essential oils and plant materials as bio-products is known as an appropriately safe strategy for controlling decay and maintaining fruit quality. Pistachia atlantica essential oil (PAO) (ranging between 0, 200, 400, 600, 800, 1000 and 1200 µl l-1) was tested for antifungal activity against Botrytis cinerea in vitro conditions. Carboxymethyl cellulose (CMC) (0, 1 and 2%) and PAO (0, 600 and 1200 µl l-1) were applied to the "Rasheh" grope for improving grape cold storage to preserve fresh fruit quality during cold stored postharvest.
