In three field trials fungicides used for stem rust (Puccinia graminis) control were evaluated to assess the effect on levels of blind seed disease, seed germination and endophyte (Neotyphodium lolii) transmission. Blind seed disease infection was reduced from 24% to 5% in one of the three trials undertaken and germination was increased by between 17 and 23% in two trials. There was a negative ...

Over the course of 2 days, top researchers in the fields of bacterial spore biology and computational biology discussed approaches to determine the cause of spore germination heterogeneity. Biological and mathematical data gaps were identified, and experimental approaches and computational strategies for modeling spore germination were presented and evaluated. As a result of these interactions,...

In this study, Ceratonia siliqua L. carob seeds harvested from both wild and cultivated genotypes in Turkey were subjected to mechanical scarification, soaking in hot water and dipping in sulfuric acid. All treatments hastened seed germination and seedling growth of carob compared to control. The germination percentage of control seeds were similar for both wild and cultivated genotypes (13%) a...

Germination is a key process in plants' phenological cycles. Accelerating this process could lead to improvment of the seedling growth as well as the cultivation efficiency. To achieve this, the effect of microwave frequency on the germination of rice seeds was examined. The physiological feedbacks of the MR 219 rice variety in terms of seed germination rate (GR), germination percentage (GP), a...

bitter asafetida (ferula asa-fetidae l.) is a wild plant of the family umbelliferae. the present study was carried out to determine the type of dormancy of the plant’s seed, and find out the most suitable treatment needed for quick germination of seeds. twelve treatments including ga3 (500, 1000, 1500 ppm), kno3 (0.1, 0.2 0.3 molar), rinsing (24, 48, 72 hour),elimination of seed coat (one year-...

Regeneration of many late-successional tree species depends on specialized safe sites. The primary objective was to investigate the roles of seedbed and moisture retention as dimensions of safe sites for the early regeneration of drought-sensitive northern white cedar (Thuja occidentalis). We hypothesized that rates of germination, survival, and growth of T. occidentalis are unlikely to differ ...

Atmospheric-pressure N2, He, air, and O2 microplasma arrays have been used to investigate the effects of plasma treatment on seed germination and seedling growth of mung bean in aqueous solution. Seed germination and growth of mung bean were found to strongly depend on the feed gases used to generate plasma and plasma treatment time. Compared to the treatment with atmospheric-pressure O2, N2 an...

The responses of two cultivars of soybean (Merr.) to a chilling treatment (4 C for first hour of imbibition) were compared. The germination of cv. Biloxi was unaffected by the treatment, while the germination of cv. Fiskeby was reduced. The phospholipid fatty acids of dry axes of the two cultivars were very similar, and, thus, could not be correlated with their responses to chilling. The fatty ...
