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...

the allelopathic potential of different concentrations (0, 5 %, 10 %, 20 % and 40%) of medicago sativa shoot extracts were assayed on germination and radicle growth of four weed species( amaranthus hybridus, amaranthus albus, solanum nigrum and chenopodium album) in a laboratory experiment as completely randomized factorial with 3 replications. the results showed that, final germination percent...

the allelopathic effects of various concentrations (0 (as control), 5 %, 10 %, 20 % and 40%) of berseem clover shoot extracts were assayed on germination and radicle growth of four weed species ( amaranthus hybridus, amaranthus albus, solanum nigrum and chenopodium album) as completely randomized factorial with 3 replications. the effect of aqueous extract concentration of berseem clover on the...

to determine the effect of seed size of sugar beet cultivars on germination and seedling vigor, a study was conducted as a 4×6 factorial experiment based on completely randomized design with 4 replications at seed and plant certification and registration institute, karaj in 2013. the treatments were toucan, dorotea, rasta, sharif, pars, and torbat cultivars and four seed width sizes including 2...

background and objectives: germination and seedling establishment are two critical and important stages during plants growing season. from seed technology viewpoint, germination refers to emergence and development from seed embryo, so that could produce normal seedling. many studies  have been done to determine germination cardinal temperatures and required thermal time for emergence occurrence...

Pyrethrum is a perennial daisy grown commercially for the insecticide that is extracted from its flowers. In order to evaluate germination and seedling growth of pyrethrum under different temperature and drought stress treatments, an experiment was conducted in seed technology laboratory of Faculty of Agriculture of Islamic Azad University of Isfahan branch in 2018. During this experiment, poly...
