Results showed that application of Cd significantly increased Cd concentration in fruits. Existence of Cd in nutrient solution significantly decreased fresh and dry weight of fruit, firmness, titratable acidity, and finally yield. Also, the negative effect of Cd stress on fruit titratable acidity and firmness was neutralized by increasing the potassium (K) level. Potassium caused an increase in total soluble solids and color by affecting a color parameter and fruits had more red color and ripeness. The treatments had no significant effect on fruit pH and pericarp thickness.","PeriodicalId":185425,"journal":{"name":"Journal of Science and Technology of Greenhouse Culture","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117323417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Beverly Watson). This research was conducted in 2015 in one of the greenhouses of Parks and Landscape Organization of Urmia and in Research Laboratories of Horticultural Science Department, Faculty of Agriculture, Urmia University. A factorial experiment, based on completely randomized design, was conducted with 2 factors of Si source (calcium silicate, potassium silicate and sodium silicate) and Si concentration (0, 50, 100, 150 and 200 mg/L) with 3 replications. Treatments were applied weekly via foliar spray for 10 weeks. Results showed that Si treatment increased leaf number and thickness, leaf fresh and dry weight, leaf chlorophyll content, soluble sugar content and protein content. Because of these beneficial effects of Si on leaf number and chlorophyll content, it can improve the photosynthesis. Potassium silicate spray caused the highest content of chlorophyll a and the highest content of chlorophyll b and carotenoid was resulted from the application of calcium silicate. The highest content of fresh and dry weight of leaf, chlorophyll a, b and total chlorophyll and carotenoid was achieved in 200 mg/L silicate application. Due to the positive effects of Si on growth characteristics and photosynthetic pigments, these materials can be used to improve the rose quality.","PeriodicalId":185425,"journal":{"name":"Journal of Science and Technology of Greenhouse Culture","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127417366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to select a suitable medium for hydroponic lemon balm, two greenhouse experiments were carried out on growing media containing different particle sizes of perlite and peat moss mixed with perlite. In the first experiment, growing media treatments were very fine perlite (<0.5 mm), fine perlite (0.5-1 mm), medium perlite (1-1.5 mm), course perlite (1.5-2 mm) and very course perlite (>2 mm) as 100% by volume. Treatments of the second experiment were mixed grades of perlite with 50% peat moss and peat moss (100% V/V). The experiments were arranged in a randomized complete blocks design with three replications. Results showed that significant differences were observed in the measured parameters in inorganic substrates (perlite with different sizes), organic substrates (peat moss) and mixture of organic and inorganic substrates. The highest fresh weight (98 g), dry weight (29.5 g), and essential oil yield (0.13 g/pot) were obtained in the treatment with perlite size of 0.5-1 mm. In the mixture of perlite and peat moss media, the highest fresh weight (189 g) and dry weight (62.4 g) was obtained in the perlite size of 1-1.5 mm. The highest essential oil yield (0.28 g/pot) was observed in pure peat moss treatment. In general, it could be concluded that although addition of peat moss to perlite substrates increased growth parameters and yield of lemon balm, but the size of perlite should be considered in the preparation of growth medium.","PeriodicalId":185425,"journal":{"name":"Journal of Science and Technology of Greenhouse Culture","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132487568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evapotranspiration in the FI, DI85, DI70, and DI55 treatments during the 66 days of the deficit irrigation application, were 337.8, 307.5, 281.1 and 244.2 mm and in the whole growth period were 396.2, 365.9, 339.5 and 302.6 mm, respectively. The plant’s morphological characteristics were decreased with decreasing the soil water content. However, in 79% of the cases, the difference between FI and DI85 treatments was not significant. Whereas, in all the cases, the difference between DI55 treatment and FI and DI85 treatments was significant. Applying deficit irrigation decreased the number of good-shaped fruits from 33.0/plant in the FI treatment to 15.6/plant in the DI55 treatment and similarly increased the number of bad-shaped fruits from 5.4 to 18.0 per plant. Crop yield and water use efficiency in the FI treatment were 18.98 ton/ha and 4.79 kg/m, which did not have significant difference with the DI85 treatment (which had a yield of 17.75 ton/ha and a water use efficiency of 4.85 kg/m). While there is not a statistically significant difference between the crop yields of FI and DI85 treatments, the DI85 treatment uses less water and gives crop yield very close to that of full irrigation treatment. Hence, the DI85 treatment can be recommended in the cultivation of Hamadanian pepper. In the severe water-scarce conditions, the DI70 treatment could be used to yield 13.48 ton/ha, which is 29% less than the FI treatment. Also, water use efficiency in the DI70 treatment was decreased by 17% compared to the FI treatment.

To evaluate application effects of amino acids on Post-harvest life of Strawberry fruits, a factorial experiment was carried out based on completely randomized design in Research Greenhouse of Ferdowsi University of Mashhad. Experimental treatments were three amino acids (Arginine, Glutamine and Alanine) at three levels (0, 500 and 1000 μM) and two cultivars of strawberry (Camarosa and Gaviota). Strawberry fruits were harvested at commercial maturity stage and transported to the laboratory. Then fruits were kept in plastic containers and stored at 4 oC. After 15 days, total soluble solids (TSS), titrable acidity (TA), flavor index (TSS/TA), total anthocyanin, total phenol, phelavonoid, total antioxidant capacity and percentage of fruit weight loss were determined. Results showed that the highest flavor index (18.41) was observed in Alanine1000cultivar Gaviota. Also, the lowest fruit weight loss was related to Alanine 500cultivar Gaviota (18%) and Arginine 500cultivar Gaviota (14.5%) treatments. These two treatments were not statistically different. The highest fruit-weight loss (65.5%) was observed in Glutamine 500cultivar Gaviota. Also, Glutamine 500cultivar Gaviota had the highest Antocyanine. It can be concluded from this experiment that application of Arginine and Alanine amino acids prior to harvest of strawberry fruits can increase their postharvest life and quality.","PeriodicalId":185425,"journal":{"name":"Journal of Science and Technology of Greenhouse Culture","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121304251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The factorial experiment, based on randomized complete blocks design, was performed at four salinity stress levels (0, 5, 10 and 15 dS/m) andn ten Achillea millefolium genotypes with three replicates. Results revealed that salinity stress of 15 dS/m significantly decreased the plant height, leaf area and width, length of ligulate florets, flower diameter, number of florets in inflorescence, days to flowering, days to 100% flowering and dry weight of the herbs. The salinity stress at 15 dS/m increased essential oil content by 18.75% compared to control treatment. The UK, Slovenia, Spain, Japan, Kandovan (Iran) and Lorestan (Iran) genotypes were not able to produce flowers in high salt stress conditions. The interaction of salinity stress and genotype was significant for all traits except for leaf width and length of ligulate florets. The US and Canada genotypes possessed the highest essential oil content and dry matter weight. The US and UK genotypes can be suggested for green space, under salinity stress conditions, due to their low height and high flower diameter. Most of the studied traits did not show significant differences at 5 and 10 dS/m salinity stress levels. Plants had good resistnce to 10 dS/m salinity stress. Moreover, evaluated traits of plants were significantly different at 15 dS/m level. Based on the obtained results, the 10 dS/m salinity level can be suggested to cultivate this plant.","PeriodicalId":185425,"journal":{"name":"Journal of Science and Technology of Greenhouse Culture","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114746739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each of these stresses have different effects on growth, metabolism and yield according to the sensitivity level and stage of the plant growth. One way of reducing the negative effects of the stresses is to use humic substances. The present study was carried out to evaluate the effects of humic acid and drought stress on morphological and physiological indices of marigold. The experiment was carried out according to the factorial arrangement, based on completely randomized design with three replications, in Department of Horticultural Science, Arak University, in fall and winter of 2016. The effects of four humic acid levels (0, 50, 100 and 250 mg/L) and three irrigation intervals (5, 10 and 15 days) was investigated on physiological and morphological traits of the marigold (root length, number of leaves and flowers, chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, phosphorus, calcium and proline contents). Results showed that root length and proline content was increased by increasing intensity of drought stress. The highest proline content was obtained by 15-day irrigation interval without humic acid and the lowest content was obtained by 5-day irrigation interval with 250 mg/L humic acid. However, drought stress reduced number of leaves and flowers, chlorophyll (a, b and total), carotenoid, and phosphorus and calcium contents. Higher levels of humic acid, particularly 250 mg/L, increased the amount of chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, phosphorus content, root length, number of leaves in the sixth week and number of flowers; but reduced the calcium and proline contents. The 250 mg/L humic acid treatment not only reduced the negative effect of drought stress, but also was able to improve the physiological and morphological characteristics. In conclusion, using humic acid, especially at higher concentrations, is recommended for increasing the irrigation interval of marigold flower.","PeriodicalId":185425,"journal":{"name":"Journal of Science and Technology of Greenhouse Culture","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126265875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, a pot experiment was set up in a completely randomized factorial design with three replications. Treatments included different salinity levels (0, 30, 60 and 90 mM sodium chloride) and vermicompost (control, unenriched vermicompost and enriched vermicompost with S. rimosus and S. griseus). Results showed that salinity stress caused a significant reduction in the root and shoot dry matter yield, nitrogen, potassium, iron and zinc concentration and potassium: sodium ratio, but increased sodium concentration and cell membrane permeability. Under these conditions, application of vermicompost maintained the structure of cell membranes, improved balance of nutrients and thus reduced the adverse effect of salinity on the plant yield. The effect of vermicomposts enriched with S. griseus and S. rimosus on maintaining root membrane permeability, improving plant nutrition and increasing salt tolerance of plants was more than unenriched vermicompost. So that the highest root and shoot dry weight in salinity of 90 mM NaCl was observed in vermicompost treatment enriched with S. rimosus. According to the results of this study, vermicompost enriched with salt-tolerant strains of Streptomyces, in addition to maintaining the balance of nutrients in saline conditions, improves morphological and physiological characteristics of cucumber plant and thereby can alleviate the damage induced by salinity stress.","PeriodicalId":185425,"journal":{"name":"Journal of Science and Technology of Greenhouse Culture","volume":"708 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123836245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
