The effect of germination temperature on antioxidant enzymes activities and seed germination of Prangos ferulacea Seeds harvested at different seed moisture content
Prangos ferulacea is a plant from the umbeliferae family that is propagated by seed germination. In order to investigate the effects of seed ripening and germination temperature on germination and some antioxidant enzymes activity of this plant seed, a two-factor factorial experiment was carried out in a completely randomized design with three replications in the laboratory of Seed Sciences and...
متن کاملPhytochrome and Seed Germination: VI. Phytochrome and Temperature Interaction in the Control of Cucumber Seed Germination.
Phytochrome control of cucumber seed germination is temperature-dependent. A prolonged exposure to radiation from broad spectrum far red sources (Pfr/P = 0.05 to 0.07) prevents germination at temperatures below 20 C. Above 20 C there is no inhibition and it appears as if there is an escape from phytochrome control. However, radiation from a monochromatic, narrow band 730 nanometer source (Pfr/P...
متن کاملEffect of Water and Temperature on Seed Germination and Emergence as a Seed Hydrothermal Time Model
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...

متن کاملEffects of Moisture and Temperature on Germination of Idaho Fescue
Germination response to varying temperatures and water stress levels during a 30-day incubation period was observed in 4 eastern Oregon collections of Festuca iduhoensis Elmer. Seeds were selected from the following habitat types: Artemisia trident&a ssp. wyomingensis/Festuca iduhoensis (ARTRV/FEID), Pinus ponderosa Dougl./Festucu idahoensis (PIPO/FEID). One stand of each habitat type was sampl...
