In order to investigate the effect of putrescine and auxin (IBA) on rooting of semi-hardwood cuttings of the GN15 hybrid rootstocks, an experiment was conducted at the Flower Biology Laboratory of Faculty of Agriculture, Tabriz University in 1994. Cuttings were obtained from Sahand Gardening Research Station. This experiment was conducted in a completely randomized design with four replications...
abstract recently weed scientist are more interested in weed management by allelopathy . the main objective of the study was to evaluate allelopathic potential of sunflower on redroot pigweed and common lambsquarter. this study was conducted in two series of laboratory and greenhouse experiments. under laboratory conditions, leaf, stem and root aqueous extracts of sunflower at 0%, 2.5%, 5%, 7.5...
Water supply in arid and semiarid regions of the world is a serious problem in crop production. Grafting may enhance water stress resistance and plants growth. In order to evaluate the effect of different cucurbit rootstocks (Flexifort, Shintoza and ungrafted cucumber) and water stress (40, 60, 90% of field capacity) on morphologic traits and yield of greenhouse cucumber (Cucumis sativus L. var...
Silicon (Si) is one of the beneficial elements for plants, which improves quantity and quality of yield, decreases evaporation and transpiration and enhances plant resistance to abiotic stresses. In order to evaluate the effect of Si and nano-silicon (N-Si) on growth, morphological and photosynthesis attributes of tomato, cultivar Falcato, an experiment was carried out in a hydroponic system, ...
in this research, the effect of foliar spraying times and different levels of farmax® nano fertilizer on morphological characteristic and dry and fresh flower yield, essential oil and chamazulene percentage of chamomile (matricaria recutita l.) cv. bodegold was studied. the experiment was factorial in the bacic of randomized complete blocked design (rcbd) with eight treatment and four replicati...
Root-knot nematode, Meloidogyne incognita, is one of the main problems in vegetable-growing regions, decreasing yield quality and quantity worldwide. Root-knot nematode management tactics mostly involve chemical control which is a threat to the environment, consequences to human health. Biological control of nematodes is considered to be one of the best alternatives to the chemical control. In ...
Smoke tree (Cotinus coggygria Scop.) is an attractive ornamental tree in landscape that has medicinal properties. In this study, the effects of different levels of salt, cow manure and vermicompost on plant growth were investigated. In a factorial experiment and completely randomized design (CRD), three levels of organic amendments (1- soil 2- 80% v/v soil + 20% v/v vermicompost, 3- 80% v/v soi...
Drought cause yield loss of soybean production is the major reason to yield losing of soybean. To improve the germination and growth of soybean seeds under drought stress; We studied the effect of the single walled carbon nanotubes (SwCNTs) material in seed germination and the physiological changes occurred under drought condition, performed SwCNTs treatments in soybean (Zhonghuang 35) seeds at...
Because of increasing trend in salinization of water sources, and inevitable using non-traditional water, a research was planned to determine the tolerance range of strawberry cv. Paros to salinity and possible role of salicylic acid (SA) in ameliorating its adverse effect on plant growth. In this research, effect of different salinity levels (0, 20 and 40 mM in nutrient solution) and SA (0, 10...
Plants deal with various stresses like salt stress in their life. Henbane is one of the important plants of potato family with numerous pharmaceutical effects. To assess the effects of salinity on growth responses of Henbane plant, experiment performed in growth chamber as pot culture based on a randomized complete design (CRD) with three replications. Seed germination percentage has been studi...
