This study was conducted to evaluate the effect of hydropriming and seed aging on germination and enzymatic properties of pinto bean under salinity stress as factorial based on a completely randomized design with four replications. Two groups of seeds (i.e., non-aged and aged seeds), two hydropriming treatments (i.e., hydro primed and unprimed seeds) and six salinity treatments (i.e., 0, 2, 4, ...

Fungal endophytes mainly belong to the phylum Ascomycota and colonize plants without producing symptoms. We report on the isolation of seed-borne fungal endophytes from Phragmites australis (common reed) that were ascribed to the genus Stagonospora. Nested polymerase chain reaction (PCR) assays revealed that a Stagonospora sp. regularly colonized reed as shown for a period of three years. In sp...

Early vigor is an imperative trait and its role become more important under drought stress condition. Genotypes with better early vigor cover above the soil plane, reduce evaporation of soil surface and increase weed competitiveness. In this research, a half diallel mating design was generated from crosses between seven bread wheat to study the genetic of early vigor. Parents and F1 progenies w...

Citation: Galland M and Rajjou L (2015) Regulation of mRNA translation controls seed germination and is critical for seedling vigor. The control of seed germination capacity is a multi-level molecular process including, epigenetic, transcriptional, post-transcriptional, translational, and post-translational regulation (Rajjou et al., 2012). Since the beginning of the twenty-first century, a wid...

Abstract: The analysis of longevity can support decisions about the length seed lot storage until commercialization, since this characteristic implies maintenance viability over time. Seed is analyzed by p50 test, which expresses time to lose 50% initial viability. Seeds with high vigor and germination have greater physiological potential and, thus, a capacity maintain quality throughout period...

The soluble sugars present in the maize (Zea mays L.) embryo may serve as important components of protection or may contnbute to the deteriorative changes occurring during seed storage. Examination of the changes in sugars during accelerated aging of maize seeds indicates that the decline in vigor is associated with a marked decline in monosaccharides and in raffinose. Sucrose content remains r...

Loss of aquatic plant species has occurred in coastal and freshwater habitats throughout the world. In particular, population and habit loss of the submerged aquatic species, Vallisneria americana Michx., have made it a potential restoration candidate. For successful restoration, reliable seed sources are vital for producing plants or for direct seeding. Seed survival and their ability to retai...

in order to study the effect of folic acid on seed reserves partitioning and early vigor of seedlings of kavir wheat cultivar, an experiment was conducted in a completely randomized design with 0, 12.5, 25, 50, 100 and 200 mm of folic acid. results of this study indicated that dry weight of seeds decreased in a same pattern in all treatments and about 6-8% of total seed was structural section. ...

A large body of research has documented the effect of seed priming ongermination, emergence and crop yield. In such research, seed priming has beenfound to have a positive, negative or no effect. Meta-analysis can help tosummarize and interpret a collection of experiments. The aim of this study was toconduct a meta-analysis to synthesize published data from studies addressing theeffect of seed ...

DOR: 98.1000/2383-1251.1398.6.77.11.1. 1575.1605 Extended Abstract Introduction: Iran is located in the arid and semi-arid regions of the world with an average rainfall of 240 mm per year, which requires rethinking of the adoption of methods. One of the alternative ways is to use organic and biological fertilizers. Biological fertilizers are considered as the main and the most important f...
