Six parents of Jatropha curcas were crossed in half diallel fashion, and the F 1s were evaluated to determine the combining ability for nine germination parameters. The ratio between general combining ability (GCA) and specific combining ability (SCA) variances indicated preponderance of additive gene action for all the characters except germination percentage, time of 50% germination, seedling...

in order to evaluation the effect of drought stress on germination indices and early seedling growth of medicinal herb dill (anethum graveolens l), an experiment was conducted in the agricultural laboratory of urmia payam noor university in 2015 as a randomized complete block design with four replications. treatments were five levels of drought stress (0, -1, -2, -3 and -4 bar induced by polyet...

to study the effects of sowing dates on seed germination and on seed vigor of 12 spring rapeseed cultivars, an experiment was performed in years 2005-2006. during the first year, 12 cultivars of spring rapeseed were planted in the research field of seed and plant improvement institute, karaj, iran. during the second year, standard germination test was conducted to study the performance of the s...

The present works were carried out to determine the impact of different municipal solid waste compost (mswc) soil extracts (Tap water, 5%, 10%, 15%, 20%, 25%, 30% and distilled water (control) obtained from mswc (degraded soil) and different mixing ratio of mswc and distilled water on the percentage of relative seed germination (RSG%), vigor index, root length, shoot length of soya bean (Glycin...

Seedling vigor is an important agricultural trait as direct-seeded rice technology becomes widely applied. In order to investigate the genetic mechanisms underlying seedling vigor in rice, seeds of 132 recombinant inbred lines (RILs) derived from 93-11 and PA64s, harvested from Lingshui and Hangzhou were cultivated in the nutrient solution, and four indices for seedling vigor were measured incl...

Drought significantly reduces yield of many crop plants including wheat in the world. Identification of wheat genotypes that can thrive on limited water is vital to boost the wheat production of rainfed areas. Forty wheat genotypes were screened for drought tolerance using 0, 7.5, 15 and 22.5% Polyethylene Ethylene Glycol 6000 solutions at PMAS Arid Agriculture University, Rawalpindi, Pakistan ...

seedling characteristics of different sunflower (helianthus annus l.) cultivars under drought stress and inoculation with the azospirillum lipoferum in a spilt-factorial layout based on randomized complete block design with three replications were evaluated. treatments included dehydration stress (seed produced on maternal plants which irrigated after 60 (desirable irrigation), 120 (medium stre...
