I N THIS STUDY we evaluated different terms of wheat seeds storage form on grain quality. This study was conducted at the Seed Technology Department during 2016-2017 years to investigate the effect of some storage conditions ,i.e. storage times (after harvest, 6 and 18 months), location (Sakha and Sids), form of wheat (grain and spike) and six wheat cultivars (Sakha 93, Giza 168, Sids 12, Misr 1, Gemiza 9 and Gemiza 11) of grain on the germination, seedling vigor, viability and some grain quality parameters from the wheat stored. The results revealed that, in both locations there was a significant increase in moisture content, E.C and acidity percentage due to long storage time also wheat stored in spike form is more resistant than wheat stored in grain form against adverse storage conditions by lower content of moisture, E.C and acidity percentage. The results illustrated that increasing storage period after harvest until 18 months caused negative effect on all characters. The highest values of germination percentage, seedling vigor, 1000-grain weight, relative density, protein percentage and viability parameters were recorded with wheat stored in spike form in both locations. There were highly significant differences among seed quality characters due to storage locations. Due to lower relative humidity value in Sids (RH=40%) compared to Sakha locations (RH=80%), Sids gave higher values for germination percentage, seedling vigor, grain viability, 1000-grain weight, relative density and protein percentage. On the other hand, results recorded highly significant differences among the tested cultivars for all studied characters mainly due to differences in the genetic constitution of these cultivars. Misr 1 then Giza 168 gave the highest values of germination percentage and seedling vigor, while Sakha 93 gave the lowest value of germination percentage and seedling vigor.

This research was applied to assess the impacts of marjoram (Origanum marjoram) and ginger (Zingiber officinale) water extract on diabetic male rats' fertility. A total of forty eight Sprague Dawley albino rats allocated into eight groups were utilized in this research. Varying doses of the extract 100, 200 and 400 mg/kg b.w )Body weight ( were utilized. Weight of testis, histological study, hormonal assay and sperm analysis were studied. Findings of marjoram and ginger demonstrated no significant change in weight of testis except at the high level, inhibition of testicular tissue peroxidation, improve testosterone (T) levels, parameters of sperm analysis such as sperm concentration and motility than the controls. Elevated serum leptin, and prolactin (PRL) with declined serum T and rise in aromatase action in testis, of the positive controls were observed than negative controls. While, diabetic rats received tested extract showed significantly decreased in leptin, prolactin and aromatase with increasing serum T. Histopathological changes, involving seminiferous tubules (ST) degeneration, with vacuolization, sloughing and decline of spermatogenic cells were also observed in controls. Orally marjoram (ME) or ginger extract (GE), with diabetic rats appeared to avoid these changes by decreased accumulated testicular lipid, increased sperm count and androgens, as well as improve testicular structure. So, this research recommends that intake of marjoram and ginger as a drink or add it to any other food product )Such as) had a positive impact on the fertility potentials of the diabetic male rats.
