Molecular mobility is increasingly considered a key factor influencing storage stability of biomolecular substances, because it is thought to control the rate of detrimental reactions responsible for reducing the shelf life of, for instance, pharmaceuticals, food, and germplasm. We investigated the relationship between aging rates of germplasm and the rotational motion of a polar spin probe in ...

The process of aging affects most, if not all, living creatures, from single celled yeast to multi-cellular mammals and plants. The DNA end-replication problem along with the tissue-limited expression of telomerase led to the telomere hypothesis of aging, where limits on cellular proliferation are genetically encoded in the lengths of a cell's telomeres. Support for this hypothesis has been fou...

Seed storability of 22 selected soybean mutant lines from Argomulyo population irradiated by gamma ray were assessed rapid aging tool, APC-IPB 77-1MM. viability and vigor parameter observed due to genetic factors. The 90% ethanol was applied for 20, 40, 60 80 min as accelerated test. M100-96-53-6 estimated that has good with less seed deterioration rate expressed slow slope germination percenta...

In this experiment, wheat plants were exposed to drought stress during seed development then we worked on the obtained seeds. The seed mitochondrial ultra-structure, and antioxidant enzymes in seedling were investigated after exposure to seed accelerated ageing. Drought stress during seed development induced some changes in mitochondrial ultra-structure. Encountering seed development to drought...

environmental conditions including metrological parameters (precipitation, temperature, humidity and etc.) various stresses and nutrition, could affect  germination and  seeds vigor during of development, ripping and leven after harvesting of soybean seed. for this, experiments of completely randomized design ( as nested)by four replications were performed in seed laboratory of gorgon universit...

Leaves from mature Griffonia simplicifolia plants were examined for the presence of leaf lectins possessing sugar binding specificities similar to the four known seed lectins (GS-I, GS-II, GS-III, GS-IV). Three (GS-I, -II, -IV) of the four known G. simplicifolia seed lectins were present in the leaves. Leaf G. simplicifolia lectins I and IV were similar to the respective seed lectins. Leaf GS-I...

Background and Objective: Aging is a natural phenomenon which can cause changes in most organs and cells. Numerous mechanisms including oxidative stress and free radical generation is involved in the progression of the aging process. Pomegranate seed oil (PSO), has different therapeutic properties including anti-oxidant and anti-inflammatory effects. In this research, the effect of PSO against ...

In order to determine the best developmental stage of soybean at which maximum seed quality is attained under different shadings (S1, S2, S3: 0, 35 and 75% shade, respectively) and irrigation treatments (I1, I2, I3, I4: irrigation after 60, 90, 120 and 150 mm evaporation from class A pan, respectively), two split plot experiments using randomized complete block design with three replications we...
