abstract a sub-sample of lentil (lens culinaris medik. cv. kimia) seeds was kept as bulk (s1) and another sample was separated to large (s2) and small (s3) seeds. a sub-sample of each size was kept as control or high vigor seed lot (a1) and the two other sub-samples were artificially aged for 2 and 4 days (a2 and a3, respectively). field performance and some physiological traits of plants from ...
an experiment was conducted to determine the aging mechanism in safflower seed using natural aging treatment (storing seed at room temperature for six years) and accelerated aging ( incubating the seed at 41?c and close to 100% relative humidity for 4 ,8 and 12 days). the results indicated that both natural and accelerated aging reduced germination percentage, seed vigor and activity of catalas...
seed deterioration is loss of seed quality, viability and vigor due to effect of adverse environmental factors. many of our crops are reproduced through seeds, and throughout the world large quantities are produced, stored and transported. seed ageing during storage may cause retardation of field establishment, and may eventually result in seedling abnormalities or even failure of emergence. du...
BACKGROUND: Seed aging is an important problem in developing countries which seeds stored in inappropriate condition. OBJECTIVES: Current research was carried out to study the effect of seed aging on quantitative parameters of wheat seeds (Chamran cultivar). METHODS: Experiment was carried out based on randomized complete block desi...
deterioration of seed is one of the most important limiting or even hindering factors in its germination. an evaluation and understanding of the factors responsible for/ and enhancing seed deterioration is of paramount importance. the main aim of this study was to determine the effects of seed deterioration on its germination and as well on the activities of antioxidant enzymes in canola culitv...
use of plant growth promoting bacteria (pgpb) and high quality of seed as agricultural inputs play important roles in sustainable crop production. to study the effects of different levels of seed aging and pgpb's application on field emergence, seedling establishment and yield of two red kidney bean cultivars in field conditions, an experiment was carried out as factorial based in a rcbd d...
Seed quality is one of the most important factors affecting seed germination and seedling growth. In order to investigate the effects of seed aging on germination and seedling growth of sunflower cultivars, a factorial experiment was conducted based on a completely randomized design with three replications in seed research laboratory of Shirvan Higher Education Complex. To create 7 different tr...
to evaluate the effects of accelerated aging and cold stress on seed germination and seedling growth indices in five oilseed rape cultivars (hyola330, hyola401, hyola420, syn3 and pr401/15e), an experiment was carried out in a completely randomized design of three replications. results indicated that the cultivars were significantly different in germination percentage, seed vigour, germination ...
Seed aging increases activity of reactive oxygen molecules and antioxidant enzymes have a key role against increased oxidative stress which is caused by free radicals. Effect of seed priming on increasing of these enzymes activity and its impacts on seed germination characteristics of deteriorated milk thistle seeds was studied in University of Mohaghegh Ardabili in 2013. Factoral experiment ba...
Effects of accelerated aging and seed priming treatments were studied on milk thistle seeds during germination process. Experiment was performed in a factorial based on Complete Randomized Design (CRD). Treatments were Salicylic acid concentrations (0, 500, 1000, 1500 and 2000 ppm) and accelerated aging for (0, 48, 96 and 144 hours under 45 °C and 95% humidity) with three replications. Our ...
