This study was conducted to evaluate the effects of accelerated aging and natural storage on seed germination and seedling heterotrophic growth of chickpea in Gorgan University of Agricultural Sciences and Natural Resources in 2014. The experiment was carried out, adopting a completely randomized design with four replications. Treatments were 8 aging levels (i.e., 2 years, and 4 years natural s...
Background and objectives: Problems of germination and establishment of plants in drought and dehydration conditions is one of the common problems in arid and semi-arid regions of the country which affects the growth and production of plant communities. Improvement of seed germination and establishment of plants under drought stress is one of the most important issues in success of rehabilitati...
Extended abstract Introduction: Nowadays exploitation of hetrotoxic characteristics of hetrotoxic plants regarding harmful effects of synthetic herbicides can most important role in weeds management and their control. In fact chemical compounds which is released by root, stem, leaf, flowers, seeds pollen, fruit and seeds can be used as bio herbicides and bio pesticides. The purpose of this s...
Variation in genetic constituent leads to increasing phenotypic expression of the quantitative characters of individuals. This variation is induced by mutation and the variability was evaluated on the quantitative traits such as, days to germination, percent germination, root length, brix percent and yield of sugarbeet mutant at M1 generation by the effect of radiation. The results were showed ...
Variation in seed weight is common within and among plant species, but few studies have attempted to document the pattern of seed weight and germination attributes for aquatic macrophytes at a large scale. This study examined within-species variation in seed weight and germination attributes and the effects of environmental factors on seed traits of the submerged plant Potamogeton pectinatus in...
Extended Abstract Introduction: Seed germination is one of the most important factors which determine the success of failure of crop establishment. In the absence of other environmental limiting factors such as moisture, temperature would determine the rate and overall seed germination. This research was conducted to investigate the effect of temperature regimes on seed germination, quantify t...
Objective: Germination is one of the most important stages of plants growth that affected by environmental stresses, especially drought and salinity. Methods: In order to study of Artichoke germination under different levels of salinity and drought, two separate experiments were performed. The four levels of salinity by NaCl (0, 50, 100, 150 mM) with three replications and five levels of drough...
in order to study the effect of intensity and exposure duration magnetic field on wheat (triticum aestivum l.) seed germination an experiment was conducted in laboratory of ferdowsi university of mashhad, iran. the experiment was including 11 treatments as three level of magnetic field intensities (pretreatment of seeds with 50, 100 and 150 mt magnetic field) and three exposure durations (10, 2...
In recent years, oat plant especially for hay yield is on demand in Turkey. this study, 167 landraces originated from Turkey were evaluated germination and some early seedling stage traits genotyped by 6K SNP Chip assay to detect candidate markers using association mapping analysis. Principal component analysis (PCA) also performed determine relationships among investigated traits.
 The va...
Low temperatures at the initial stages of rice development prevent fast germination and seedling establishment and may cause significant productivity losses. In order to develop rice cultivars exhibiting cold tolerance, it is necessary to investigate genetic resources, providing basic knowledge to allow the introduction of genes involved in low temperature germination ability from accessions in...
