In order to assess seed deterioration of soybean at Ardebil province, this study was conducted as a factorial experiment based on randomized complete block design in 2014. The treatments consisted of germination ability, seed moisture content and seed storing conditions. Germination ability treatment was concluded of three germination levels: 80%, 85% and 90%. Also, three rates of seed moisture...
Seed deterioration is when a seed loses its vigor and eventually viability. viability an important trait that directly influences seedling emergence crop yield. The rate of varies on several factors. Our main aims were to express the methods for testing deterioration, factors influencing aging, stages changes associated with Practical approaches overcome role reactive oxygen species during agin...
High temperature and humidity (HTH) stress during soybean seed development and maturity in the field easily leads seed to pre-harvest deterioration. However, how proteins and their involved pathways in developing soybean seed systematically cause deterioration is still not largely understood. To reveal it, we compared the proteome composition of developing seed (R(7) period) of a pre-harvest se...
Extended abstract Introduction: Seed deterioration is associated with oxidative stress and uncontrolled accumulation of reactive oxygen species. Seeds have a group of enzymatic and non-enzymatic antioxidants that protect them against reactive oxygen species and help maintain seed vigor and support seed germination processes. The response of different cultivars to seed deterioration is differen...
Seed ageing is influenced by two environmental factors, RH and temperature. The deterioration of the stored seed is a natural phenomenon and the seeds tend to lose viability even under ideal storage conditions . Autooxidation of lipids and increase in the content of free fatty acids during storage period are the main reasons for rapid deterioration of seed of oil plants. Accelerated ageing has ...
Experimental seed aging approaches intend to mimic seed deterioration processes to achieve a storage interval reduction. Common methods apply higher seed moisture levels and temperatures. In contrast, the "elevated partial pressure of oxygen" (EPPO) approach treats dry seed stored at ambient temperatures with high oxygen pressure. To analyse the genetic background of seed longevity and the effe...
Data presented here are associated with the article: "In-depth proteomic analysis of soybean (Glycine max) seeds during controlled deterioration treatment (CDT) reveals a shift in seed metabolism" (Min et al., 2017) [1]. Seed deterioration is one of the major problems, affecting the seed quality, viability, and vigor in a negative manner. Here, we display the gel-based and gel-free proteomic da...
The need to identifying seeds with low vigor and poor emergence led to introduce of various seed vigor tests. The purpose of this experiment was to assess the ability of controlled deterioration test for evaluation of seed vigor and prediction of oilseed rape seed lots emergence in the field. Samples of 19 seed lots were obtained from nineteen farmers of Razavi and Northern Khorasan Provinces...
