Abstract Salinity is one of the most important factors limiting plant growth and production around the world. Gibberellic acid is known as a strong growth stimulator, effective on seed germination and breaking of seed dormancy in various plant species. In order to study the response of Safflower,Sofeh cultivar, to salinity stress, a factorial experiment was conducted based on a randomized...

In order to evaluate the effect of hydropriming and Salinity stress on germination indices Niger, a factorial experiment was conducted in randomized complete block design with four replications at seed research laboratory Shahrekord University. treatments were applied five levels (0, 25, 50, 100 150 mM NaCl). Hydropriming two (control 6-hour distilled water). Results showed that effects water s...

A study was carried out to test whether a single count of radicle emergence (RE test) would correlate with the storage potential seed lots cucurbit ( C. maxima × moschata ) rootstock cultivars. The RE performed by counting percentage between 26 and 100 hours germination. Seed longevity determined at 75% relative humidity 35°C over days, survival curves constructed based on normal germination pe...

Magnetic field  improved germination parameters. The germination of Catharanthus roseus seeds is lost under salinity conditions. The effect of different strengths of magnetic field and exposure durations on the germination of C. roseus seeds under salinity conditions (19 mS cm-1) were investigated. The experiment was conducted  with factorial arrangement based on a completely randomized design ...

Seed germination is the key step for successful establishment, growth and further expansion of population especially for alien plants with annual life cycle. Traits like better adaptability and germination response were thought to be associated with plant invasion. However, there are not enough empirical studies correlating adaptation to environmental factors with germination response of alien ...

Nowadays, in many rangelands, due to over grazing, and problems that some plantshave in germination, the rate of forage production is greatly reduced. So to take advantages ofthe benefits of such plants, it is necessary to identify and remove barriers of germination andestablishment of suitable plants. The present study was designed to investigate differenttreatments of breaking dormancy and st...

abstract there is a world-wide effort to reduce the amount of chemicals used in crop production by introducing modern biological and ecological methods. one possible alternative is allelopathy. a laboratory trial was carried out to investigate of alleopathic potential of angelica . in this study the effect of different concentrations of aqueous extract of angelica herb was investigated on seed ...

The aim of this study was to determine the effects of different plant growth regulators, NAA (0 mg/l, 50 mg/l and 100 mg/l) and GA3 (0 mg/l, 50 mg/l and 100 mg/l), with various boron concentrations (0 mg/l, 50 mg/l and 100 mg/l) on pollen germination of ‘Şaba’, ‘Rabie’ and ‘Padre’ almond cultivars in 10% sucrose and 1% agar medium at 24°C in dark conditions. The results showed that different tr...

Cadmium (Cd) is extremely toxic metal and reduces plant growth. Therefore, study was conducted to evaluate the effect of various Cd levels 0, 5, 20, 50 and 80 mg L on seed germination and seedling growth of four wheat cultivars (Sehar-06, Fareed-06, Inqlab-91, Chakwal-50). Cadmium showed toxicity at 5 mg L in case of root and shoot growth whereas 20 mg L in case of seed germination and germinat...
