We attempted to create a new germplasm of cucumber cultivar Chinese long (9930) using different doses of ethyl methyl sulfonate (EMS) to induce variability. We tested EMS concentration (0, 0.5, 1.0, 1.5, 2, 3% v/v) with post-treatment (0.1 M Na2S2O3 and water), EMS concentration (0, 0.5, 1.0, 1.5% v/v) over different treatment times (8, 16, 24 h), and EMS concentration (0, 0.5, 1.0, 1.5% v/v) w...

The physiological process of germination depends on several environmental factors such as temperature, water potential, light, nutrients and smoke. Water and temperature are determinant factors for seed germination. Both factors can, separately or jointly, affect the germination percentage and germination rate. The effect of temperature on germination and water potential on germination canoften...

abstract this experiment, conducted to examine the effects of temperature and photoperiod on seed germination of watergrass (echinochlo aoryzoides) as a new-introduced and barnyardgrass (e. crus-galli) as a common weed species in rice fields of guilan province. this study was consisted of two separate experiments. at the first study, germination responses of two species to different temperature...

In this study, Ceratonia siliqua L. carob seeds harvested from both wild and cultivated genotypes in Turkey were subjected to mechanical scarification, soaking in hot water and dipping in sulfuric acid. All treatments hastened seed germination and seedling growth of carob compared to control. The germination percentage of control seeds were similar for both wild and cultivated genotypes (13%) a...

Isabgol (Plantago ovata Forsk) seed germination and emergence in response todrought (Polyethylene glycol 8000) and salinity stress (NaCl), temperature, pH andplanting depth were studied in laboratory and greenhouse experiments. Base,optimum and ceiling germination temperature were estimated as 3.35, 21.24 and35.04 oC, respectively. Isabgol seed is rather tolerant to low water potential and high...

Five cycles of germination NaC1 tolerant alfalfa and the source population, 'Mesa Sirsa', were germinated in four salt solutions (NaC1, NaNO3, KC1, and KNO3) and Mannitol to try to determine the general mechanism involved in seed germination salt tolerance. Average germination over all germplasm sources in NaC1, NaNO3, KC1, KNO3, and Mannitol were 44.80, 38.88, 36.24, 29.07, and 60.93 percent, ...

a better understanding of the factors influencing the germination of weed seeds could facilitate the development of more effective cultural weed management practices. the aim of this research was to determine the effects of environmental factors on seed germination of cutleaf groundcherry (physalis angulata l.). results showed that application of gibberellic acid (ga3) was effective treatment f...
