    Opis:
    Safe production of leafy vegetables is more important than other horticultural crops due to their significant contribution in health promotion of consumers. In present study, the growth and nutritional quality of sweet basil plants (Ocimum basilicum L.) were evaluated under some organic compared to chemical NPK fertilizing treatments. A non cultivated soil was used in the experiment, and treatments were arranged in completely randomized design with four replications. Manure in 20 and 40% of pot volume, vermicompost in 20 and 40% of pot volume, biophosphate, NPK fertilizer and a no fertilizing control were applied to plants. The results showed that plant growth and biochemical characteristics were differently affected by organic and chemical fertilization treatments. Vermicompost particularly in 20% of pot volume resulted in highest growth and quality parameters, while the lowest values recorded in 40% manure treatment. The leaf content of ascorbic acid, essential oil, protein and minerals (P, K, Mn, Cu) were highest in 20% vermicompost, whereas leaf content of Mg, Fe and Zn was highest in 40% vermicompost treatment. Leaf nitrate content was significantly reduced in all organic treatments than NPK fertilization. Biophosphate also improved the yield and quality traits compared to unfertilized plants, while manure in both quantities reduced most of the traits (leaf vitamin C, oil yield and protein content) except the content of phenols. This indicates that processing as vermicompost can be a better way of manure application for basil production.

    Opis:
    This study was conducted to evaluate the effects of higher conductivity of nutrient solution created by nitrate or chloride salts of potassium and calcium on growth characteristics of pepper plants (Capsicum annuum var annuum) during four months of growth period. Two EC5 and EC8 dS/m of Hoagland nutrient solutions were prepared using various salt combinations, namely: KCl + CaCl2, KNO3 + CaNO3, and KNO3 + CaNO3 + NaCl. Hoagland nutrient solution with EC 1.8 dS/m served as a control. Higher conductivity treatments had different effects on pepper plant growth. The most significant reduction in growth parameters of plant height, shoot fresh weight, fruit yield and nutrients uptake was in plants treated with KCl + CaCl2 particularly at EC8. Application of KNO3 + CaNO3 particularly at EC5, showed no difference as compared to the control regarding many growth parameters. Application of KNO3 + CaNO3 at EC5 resulted in higher shoot fresh weight compared to the control. All salinity treatments, except from KNO3 + CaNO3 at EC5, reduced the fruit yield compared to the control. Treatments of KCl + CaCl2 and KNO3 + CaNO3 + NaCl particularly at EC8 of nutrient solution, resulted in higher leaf proline concentration, catalase and peroxidase enzymes activity compared to the control. Other conductivity treatments showed no difference in catalase or peroxidase enzymes activities. Significantly the lowest amount of leaf N, K, Mg and Ca was in KCl + CaCl2 at EC8. On the other hand, the highest leaf macronutrient concentrations were in KNO3 + CaNO3 at EC5 and/or EC8 that showed only higher leaf N and Ca values compared to the control. Leaf micronutrient concentrations were the highest in KNO3 + CaNO3 at EC5 that generally showed no difference with control plants. However, application of KCl + CaCl2 particularly at EC8 and to less extent KNO3 + CaNO3 + NaCl at EC8, reduced the leaf micronutrient concentrations. Application of KNO3 + CaNO3 at EC5 increased and KCl + CaCl2 or KNO3 + CaNO3 + NaCl at EC8 decreased the leaf Fe concentration compared to control plants.

    Opis:
    Khatouni melons are a major horticultural crop that is produced mainly in semi arid and arid regions of Iran. The plant root characteristics can significantly affect many growth traits, including water and nutrients uptake under such dry conditions. On the other hand, nutrient elements concentration and their ratios can strongly affect the root morphophysiological and structure. In this study, the growth and root system characteristics of Khatouni melon was evaluated under various potassium (K) levels of nutrient solution. A rhizobox system with sand-hydroponic culture was applied. Hoagland formula was used for nutrient solution preparation, and different potassium levels of 0, 59, 118, 176 and 235 mg L–1 K of nutrient solution were applied to plants, while other nutrients were kept relatively unchanged. The results showed that the highest shoot fresh weight, leaf area and SPAD value were at 235 or 176 mg L–1 K, whereas the root characteristics were affected by K treatments in different patterns. The highest root fresh weight was in plants treated with 118 mg L–1 K, whereas root dry weight was significantly lower in treatment without K nutrition than other K levels of nutrient solution. Plant root diameter was thickest at 176 mg L–1 K and it was longest at 118 mg L–1 K, whereas the shortest roots were at 235 mg L–1 K of nutrient solution. Root area was the highest at 118, 176 and 235 mg L–1 K of nutrient solution. Root nutrient concentration of N, K, P, Ca and Fe was the highest at 118 or 176 mg L–1 K; however, the lowest amount of root Mg and Fe was in plants treated with 235 mg L–1 K. For other traits of root and shoot growth, the lowest records were in treatment without K nutrition. The results indicate that shoot or root growth characteristics of Khatouni melon can be improved by moderate to high, or moderate potassium levels.

    Opis:
    This study was done using three nitrogenous compounds to evaluate their effects on postharvest characteristics of chrysanthemum (Chrysanthemum indicum) cut flowers. The study consisted of three separate and parallel experiments, in which ammonium sulfate, calcium nitrate and potassium nitrate were used in different concentrations of zero, 50, 100, 200 and 500 mg dm ‒3 N for pretreatment of stems for 6 hour before transferring to holding d-water solution. The results showed that petal ion leakage and leaf SPAD values were increased by increasing ammonium sulfate, but not calcium or potassium nitrate. Petal carotenoids were increased by pretreatment of ammonium sulfate and potassium nitrate. There was constant increase in water uptake by increasing the levels of calcium nitrate and potassium nitrate, while ammonium sulfate at high concentrations (200 and 500 mg dm ‒3 N) resulted in significant less water uptake compared to control. Ammonium sulfate in 50 and 100 mg dm ‒3 increased shelf life of pretreated stems, but higher concentrations significantly reduced cut flowers shelf life. Increasing concentrations of calcium nitrate and particularly potassium nitrate have led to prolongation of flower shelf life to 12 days compared to 6 days of control. The results indicate that pretreatment of chrysanthemum cut flowers with ammonium sulfate in rather low concentrations or with moderate to high concentrations of calcium nitrate or potassium nitrate can significantly improve shelf life and postharvest flower qualities.

    Opis:
    Landscape plantations are significantly water demanding in many parts of the world, particularly in dry regions. Adequate water supply is the main limiting factor behind landscape development, maintenance and beauty in such environments. On the other hand, monitoring the growth response of ornamental and landscape plants to irrigation water containing heavy metals can be useful in management and application of municipal wastewaters to these plantations instead of application in edible vegetable crops production, which is common in many urban areas. In the present study, one year old seedlings of Judas tree (Cercis siliquastrum) were irrigated for two years with water containing 0, 15 or 30 mg L–1 of lead (Pb) in absence or presence of cadmium (0 or 5 mg L–1) in a factorial design, and under greenhouse conditions. Heavy metal treatments had no significant effect on leaf SPAD value; however, plants treated with Pb15Cd0 combination had significantly higher SPAD value than Pb30Cd5 combination that showed the lowest leaf SPAD value. Increasing the lead and cadmium levels of irrigation water increased the number of chlorotic and necrotic leaves of plant than control, whereas it reduced the average leaf area and new shoot growth. The control plants or plants treated with lower level of heavy metals showed the highest leaf area and new shoot growth. Leaf photosynthesis rate was significantly reduced in all heavy metal treated plants than control plants, as the lowest amount was in Pb30Cd5 combination treatment. All heavy metal treatments showed higher leaf soluble carbohydrates and proline content than in control plants. Leaf soluble carbohydrates were highest in Pb30Cd0 and Pb30Cd5 treatments, and leaf proline was highest in Pb30Cd5 and Pb15Cd5 treatments. The results indicate that Judas tree is a relatively tolerant species to high concentrations of Pb and Cd in root medium added through the irrigation water, and long term dual application of these heavy metals can have additive harmful effects on plant growth.

    Opis:
    Xeriscaping focus on the use of drought tolerant species of plants for environmental sustainability leading to the conservation of natural resources. We need to look for drought tolerant, water efficient plant species. Present research was aimed to assess the water use efficiency of Leucophyllum frutescens (silvery) for its adaptability and potential as xerophyte. In this study, seven treatments were applied were 100% field capacity was considered as control while 85%, 70%, 55%, 40%, 25% and 5% field capacities were taken as different drought levels. Effect of drought commenced at 40% field capacity and lower drought treatments as decrease in shoot and root fresh and dry weight, root length, leaf area and leaf area index and leaf firing percentage increased with severity of drought compared to 100% field capacity. Physiological parameters including water use efficiency (A/E), leaf water potential (ψleaf), stomatal conductance (gs), photosynthesis rate, cell membrane stability and total chlorophyll contents proved that this plant species can tolerate severe drought conditions. Positive correlation was found among most of the attributes but leaf temperature was negatively correlated with leaf water potential, photosynthesis rate, cell membrane stability, and chlorophyll contents. Moreover, regression analysis between various morphological and physiological attributes showed the predictive power of the model yielding significant results for leaf area and cell membrane stability (R2 = 0.74), root length and photosynthesis rate (R2 = 0.65), leaf temperature and chlorophyll contents (R2 = 0.43) and leaf area and leaf water potential (ψleaf) (R2 = 0.93).
