in order to investigate the effects of seed inoculation with plant growth promoting rhizobacteria (pgpr) on germination components and seedling growth of corn (zea mays l.), a factorial experiment based on randomized complete block design with three replications was conducted at the seed technology laboratory of mohaghegh ardabili university, iran, during 2008. studied factors were: corn cultiv...

this study examined suitable mechanized methods to seed rice in dry-bed conditions using dried seeds and determined the most suitable varieties for each method. the experimental design was strip-plots in a randomized complete block design with two factors (seeding methods and rice varieties) and three replications. the testing took place during 2003-2004 at the shavour agricultural research sta...

to better understand seed priming that improve seed germination and seedling uniformity, we examined the physiological role of osmopriming in germination of bread wheat (triticum aestivum l.) seed embryos by a proteomic approach. for this purpose, we used two systems. the first system consisted of osmo-primed seeds by peg 6000 at -0.8 mpa at 15?c for 24 hours, followed by air drying at 15?c, an...

Introduction Organic seed treatments have been limited in organic production, until recently. Agricoat Natural IITM, is reported to be “an organic liquid biological seed treatment applied as a seed film coating and formulated with beneficial microbes, macro and micro nutrients, amino acids, organic acids, enzymes, proteins, vitamins, and minerals.” Natural IITM also is applied to “promote root ...

Abstract: Seed conditioning improves germination uniformity, speed, and dormancy release. This work aimed the study physiological of Urochloa humidicola cv. Llanero, using two lots dormant seeds conditioned by imbibition with water, commercial bioregulator (auxin, gibberellin - 0.144 mM cytokinin), (0.144 1.44 mM) or 5% ethanol. Germination, dormancy, SOD activity, MDA H2O2 content were evaluat...

background and objectives: seed vigour is the resultant of a broad range of physiological processes which have genetic background. the study of genetic variation, play an important role in enhancing the ability of breeders in selection and breeding operation. this study aimed to evaluate rice genotypes with the physiological and morphological characteristics related to seed vigour and grouping ...

It was evaluated the damage caused by Bruchus pisorum on the germination ability of pea forage cultivars. Result of damage in seeds with parasitized larva was a significant decrease of the germination by 16.4% percentage points, the length and weight of primary radicle by 16.8 and 24.5%, the length and weight of plumule by 12.3 and 14.1%, the vigor index of primary radicle and plumule by 32.5 a...

understanding the seed germination response of cultivated genotypes to temperature is important, agronomically. the genotypes that germinate in lower temperatures could be useful for situations (such as late winter plantings) where temperatures are low in germination stage. therefore, this experiment was conducted to study the cardinal temperatures, response to sub- or supra-optimal temperature...
