Effect of different sowing dates on Azivash (Corchorusolitorius) seed quality
This study was conducted at the Gorgan University of Agricultural Sciences and Natural Resources farm, Iran, Golestan province with about 600 mm annual rainfall in order to evaluate the effect of different sowing dates on Azivash (Corchorusolitorius) seed quality, using a randomized complete block design with three replications on 2013. Treatments were four sowing dates such as May 5, ...

متن کاملElevated Levels of Ethylene During Germination Reduces the Time to Emergence in Impatiens
Impatiens seeds treated with the ethylene biosynthetic precursor 1-aminocyclopropane-1-carboxylic acid (ACC) had reduced times to radicle protrusion and seedling emergence. Sixty hours after imbibition, 68% more seeds showed radicle protrusion on media containing 0.1 or 1.0 mM ACC compared to seeds germinated on water alone. Subsequently, ACC was effectively “loaded” into impatiens seeds using ...
متن کاملPhytosulfokine-α Controls Hypocotyl Length and Cell Expansion in Arabidopsis thaliana through Phytosulfokine Receptor 1
The disulfated peptide growth factor phytosulfokine-α (PSK-α) is perceived by LRR receptor kinases. In this study, a role for PSK signaling through PSK receptor PSKR1 in Arabidopsis thaliana hypocotyl cell elongation is established. Hypocotyls of etiolated pskr1-2 and pskr1-3 seedlings, but not of pskr2-1 seedlings were shorter than wt due to reduced cell elongation. Treatment with PSK-α did no...
متن کاملSeed Priming Increases Germination and Seedling Quality in Antirrhinum, Dahlia, Impatiens, Salvia and Zinnia Seeds
This study was carried out to investigate the effect of hydropriming on seed germination and seedling growth of five different flower seed species (Antirrhinum, Dahlia, Impatiens, Salvia and Zinnia). Hydropriming (20oC, 24 h), surface dried or dried back afterwards, was found to increase germination percentage, seedling emergence and fresh and dry weight. In all species, the maximum advantage i...
