weed chemical control has negative results on agroecosystems. therefore, identification of cultivars tolerant to weeds has importance in nonchemical management. so, in this study, the tolerance of some alfalfa cultivars was studied to dodder. anexperiment was conducted at research farm and laboratory of shahed university in 2011. the farm experiment was done as split plot in time in randomized ...

In an effort to improve and promote the propagation of Terminalia sericea, the effects of temperature, photoperiod and growth regulators on seed germination were investigated. Seeds were tested with different temperature regime (10, 15, 20, 25, 30, 35 and 40C) and in photoperiod (4/20, 8/16, 12/12, 16/8 light/dark hrs and 24 hours continuous dark). Pre-treatments with growth regulators were don...

Species of Smilax, also known as greenbrier, are widely distributed in Brazil and their commercial trades are carried out by the extractivism of native species. We the aim to provide information about the germination and development of seedlings in four Smilax species, different experiments were developed under controlled conditions. We evaluated two germination treatments: temperature (30 degr...

there is substantial diversity in achillea biebersteinii plants in iran. it has considerable different biological activities including antibacterial, antifungal, antioxidant, insecticidal, herbicidal and wound healing. research improvement for medicinal plants depends on the available genetic diversity. the assessment of genetic variability could increase the information for breeding programs. ...

Effects of different carbon sources on growth and production of antifungal agent(s) by Gymnopilus spectabilis were investigated. Different carbon sources including; Glucose, fructose, lactose, maltose, manitol and sucrose at the concentration of 10 g/l and slow releasing carbon sources including malt extract and soluble starch at the concentration of 2g/l were used. Inhibition of spore germinat...

The seed of oilseed plants, including Arabidopsis and several crop species, such as soybean, sunflower, and canola, contain a major store of oil in the form of triacylglycerol (TAG), which provides carbon and energy for seed germination and seedling growth. During germination and seedling development, TAG stored in oil bodies is broken down into fatty acids through the action of lipases. Fatty ...

1 Faculty member,Agricultural and Natural Resources Research Center of Yazd, Yazd, Iran ABSTRACT. Seed germination and seedling growth are critical stages in the life cycle of a plant, especially under adverse abiotic stresses. Seed germination negatively affected by stress conditions. Seed priming techniques have been used to increase germination characteristics and improve germination uniform...
