priming is one of the seed enhancement methods that might be resulted in increased seed performance (germination and emergence). the objective of this research was to evaluate effect of priming on seed emergence and yield under wide ranges sowing dates in cotton. treatments were combinations of 6 sowing dates and 2 seed treatments (control and primed seeds). hydropriming method was used; seeds ...
In order to study the effect of seed priming on morphophysiological characteristics of seedlings of chickpea (Cicer arietinum L.) under salinity stress, a factorial experiment based on completely randomized design with three replications was conducted at the Research Center for Plant Sciences, Ferdowsi University of Mashhad, Iran, in 2011. In this study, osmotic solutions of NaCl with electri...
Saccharomyces cerevisiae S1, which is a locally isolated and improved strain showed viability at 40, 45 and 50°C and produced ethanol at 40, 43 and 45°C. When the cells were given heat shock at 45°C for 30min and grown at 40°C, 100% viability was observed for 60h, and addition of 200gL(-1) ethanol has led to complete cell death at 30h. Heat shock given at 45°C (for 30min) has improved the toler...
A large body of research has documented the effect of seed priming ongermination, emergence and crop yield. In such research, seed priming has beenfound to have a positive, negative or no effect. Meta-analysis can help tosummarize and interpret a collection of experiments. The aim of this study was toconduct a meta-analysis to synthesize published data from studies addressing theeffect of seed ...
In order to evaluate the effect of seed priming on salinity modification of safflower (cv. Goldasht), a hydroponic experiment was conducted at Research Greenhouse of Vali-e-Asr University of Rafsanjan, Iran, in 2009. Priming treatments at 4 levels (no priming as control, and priming with distilled water, NaCl and Ca(NO3)2 for 24 hours) and salinity treatments at 4 levels (0, 8, 16 and 24...
To evaluate the effect of priming on seed germination of Cucurbita pepo in drought stress conditions, a factorial experiment was conducted as completely randomized design with three replications. Treatments included drought stress at five levels of osmotic potential (zero, 0.3, 0.6, 0.9 and 1.2 MP), priming at levels of GA3 (250 ppm to 24 hours), KNO3 (0.2% for 24 hours) Hydro prime (H2O) (to 2...
In order to evaluate the effect of seed priming and inoculation of two mycorrhizal species on a number of physiological characteristics, yield and yield components of a wheat cultivar (Parsi) in salinity stress conditions, an experiment was conducted as a split-plot factorial based on a randomized complete block design with three replications in the years 2014-15 and 2015-16 at Isfahan Jihad Tr...
To investigate the effect of quinine seed priming on morpho-physiological and biochemical traits of seedlings, a factorial experiment was conducted in a completely randomized design with four replications at the seed processing laboratory of the Shahed University of Tehran. Experimental factors included two levels of seed age (one-year old and four-year old) and four priming treatments (control...
Soil salinity affects a large part of the region in Iran. Salinity covers 12.5% oftotal area of the country. Priming of seeds in sodium chloride and water (hydro-priming)has been reported to be a simple technique for enhancing the seedling establishment andgermination performance in the seeds of many crops and small seeded grasses under thestress conditions. Therefore, the aim of this research ...
