Non-aged and aged (40 °C for 4, 6, 8 and 10 d) seeds of safflower were subjected to priming with ascorbic acid at concentrations of 0, 0.28 and 0.56 mM. In this research germination percentage and rate, seedling vigour, shoot and root length, shoot and root dry weight, malondialdehyde, catalase activity, superoxide dismutase activity and protein content measured. The results showed that germination and seedling growth decreased with aging increment. In all levels of aging, germination percentage and rate, shoot and root length, shoot and root dry weight increased at 0.28 mM ascorbic acid than other concentrations. Accelerated aging not only resulted in increased malondialdehyde, but also in decreased catalase activity, superoxide dismutase activity and protein content. Priming with 0.28 mM ascorbic acid decreased malondialdehyde after 12 hours imbibition, whereas increased catalase activity, superoxide dismutase activity and protein content under aging. The results suggest that aged safflower seeds priming with 0.28 mM ascorbic acid improves the germination and seedling growth by reducing membrane peroxidation and increasing the activities of catalase and superoxide dismutase enzymes after 12 hours imbibition In order to study the effect of ascorbic acid on germination and some physiologic characteristics of aged safflower an experiment was conducted as factorial arrangement in completely randomized design with three replications.

For this purpose a factorial experiment in a completely randomized design with three replications was carried in the Shahed University of Tehran in 2015. The first factor was different concentrations of Selenium (0, 0.5, 1, 1.5 and 2 percent) and the second factor of priming time (0, 8, 16, 24 and 32 hours). The results indicate that the effect of the concentration and priming time was significant on germination percentage, germination rate, mean daily germination, germination uniformity, germination value, seedling length and vigor index. The interaction of concentration in priming time had a significant effect on the level of one percent on traits of germination rate, mean time germination, daily germination rate, germination uniformity and seedling length. With increasing concentrations of selenium from 0 to 2%, were observed significant increases in germination percentage, germination rate, mean daily germination, germination value, and seed vigor index. So that the highest average traits observed in concentrations of 2% and lowest in 0%. The highest germination rate in priming for 8 and 24 hours in concentration of 2% with an average of 4.50 and 4.33 seeds per day, respectively.

The interaction of two studied factors (cultivar×priming) was not significant. Also the results showed the significant effect of the cultivar factor on raw juice purity, molasses sugar and dry matter traits. In general, it can be stated that water used in prime environment can be considered as one of the main reasons for superiority of treatments in terms of final yield.

University of Guilan Iranian Journal of Seed Sciences and Research 2476-3780 4 3 2017 11 22 Review paper: Seed Deterioration Review paper: Seed Deterioration 125 143 2512 10.22124/jms.2017.2512 FA Bita Oskouei Agricultural Research, Education and Extension Organization (AREO), Seed and Plant Certification and Registration Institute (SPCRI), Karaj, Iran Saman Sheidaei Agricultural Research, Education and Extension Organization (AREO), Seed and Plant Certification and Registration Institute (SPCRI), Karaj, Iran Journal Article 2017 06 25 Seed deterioration is an undesirable and harmful process in agriculture. This process leads to reduction in seed quality, viability and vigor. Losses in seed quality occur during field, harvesting and storage. Field weathering occurs when the seed exposure to in appropriate conditions. Several factors contribute to the susceptibility for seed deterioration. The most important of them are temperature, relative humidity, seed moisture content and damages caused by microorganisms and insects. Also seeds are very susceptible to mechanical damage after harvest. The rate of deterioration fluctuates from one apecies to another and also among varieties of the same species. It is difficult to maintain seed viability due to changing environmental conditions. However, the seed quality and viability during storage depending on the initial quality of seed and storage manner. Seed deterioration is associated with various cellular, metabolic and chemical variations including lipid peroxidation, membrane disruption, DNA damage, impairment of RNA and protein synthesis. These changes is evident as a reduction in percentage germination, produce week seedlings, loss vigor ultimately seed death. Seed deterioration is an undesirable and harmful process in agriculture.
