In order to evaluate the effect of seed priming on some effective physiological parameters on seed germination of pea (Pisum sativum L.) under chilling stress, a factorial experiment was conducted in completely randomized design with four replications. Treatments were consisted of priming treatments (hydropriming, halopriming, osmopriming and no priming) and temperature (3, 6, 9, 12 and 15 ˚c)....
In order to investigate different treatment effects on germination in Gundelia tournefortii, three factorial experiments were carried out in the completely randomized design with three replications. The first factor was stratification at 4oC in three levels including 0, 3 and 6 weeks, the second factor was mechanical scarification in two levels including seeds with/without scarification and the...
Fire plays an important ecological role in Mediterranean-type ecosystems. Many Mediterranean plant species exhibit enhanced germination capacity when exposed to heat. In the present study, the effect of high temperatures and exposure times on germination of Turkish red pine (Pinus brutia) was analyzed in order to reveal the response of seeds to fire and the implications on species regeneration....
augment of germination rate is important in seedling establishment and crop yield. a set of study in laboratory & field conditions at agronomy department of university of tehran was conducted during 2004-2005. in lab. experiment the effects of seed priming was evaluated on germination indices (germination percentage and rate) of chickpea genotypes in a factorial experiment of 4×3×2 arranged in ...
This study was conducted to evaluate the effect of hydropriming and seed aging on germination and enzymatic properties of pinto bean under salinity stress as factorial based on a completely randomized design with four replications. Two groups of seeds (i.e., non-aged and aged seeds), two hydropriming treatments (i.e., hydro primed and unprimed seeds) and six salinity treatments (i.e., 0, 2, 4, ...
The present study conducted to investigation the forage quality and germination status of Capparis spinosa in Niatak Hirmand rangelands. Forage quality indices were analyzed by four replications on three phenological stages (vegetative, flowering and maturity stages) randomly. The experiment included 19 treatments to improve seed germination condition. Treatments included physical such as scrap...
Mechanization and simplification are inevitable trends in agriculture production to decrease input demands and simultaneously improve resource use efficiency. Dry direct-seeded rice is a resource-saving cropping system and has been considered as a replacement for traditional transplanted rice. However, the poor establishment of dry direct-seeded early rice, primarily induced by chilling stress,...
Effect of various concentrations of nickel (100, 200, 500 and 1000 microM) and recovery treatments of boron (50 and 100 microM) and copper (15 and 75 microM) each with 200 microM and 500 microM of nickel on germination, growth, biomass, chlorophyll, carotenoids, pheophytin, amylase, protein, sugar as well as activity of catalase and peroxidase were studied in radish (Raphanus sativus cv. Early ...
Kiwifruit is a fast-growing deciduous woody vine that can be propagated in several ways. Nevertheless, seedlings have a strong and widespread system of roots than cuttings. The aim of this study was to find a simple and practical method for farmers to increase the germination percentage of kiwifruit seeds. This study was performed in a completely randomized design with five treatments of Cold S...
Prspopis Juliflora and acacia Acacia victoriae species of precious and semi-arid and arid regions that are compatible with wood and charcoal production, soil conservation, forage production and medicinal value are very important and acacia, and stimulated their germination has been studied. Treatments used to overcome seed dormancy were treated with concentrated sulfuric acid 98% (H2so4), 15 mi...
