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...

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...

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...

Extended Abstract Introduction: Structural and physiological delicacy of soybean seeds is known as an important quality indicator in the cultivation of this plant, but at the same time, the most chronic problems of soybean seed quality are the reduction of seed quality during storage and before sowing. The effect of some nutrients on the quality of soybean seeds under accelerated aging stress ...

To study the effect of production region and seed size on germination indices and heterotrophic growth components of peanut seedling, a study was performed in three peanut fields in Astaneh Ashrafieh and Agronomy Laboratory of Rasht Islamic Azad University from 2010 to 2012. This research was carried out using the standard germination, cold and accelerated aging tests. Tests were performed usin...

The effect of seed rate of alfalfa (Medicago sativa L.) and efficiency of plant growth promoting bacteria (PGPR) that facilitates phosphorus uptake with different doses of phosphate fertilizer was evaluated on seed quality. For this purpose, the germination and seed vigor tests before and after accelerated aging were performed in a split split plot experiment based on randomized complete block ...
