Barley (Hordeum vulgare L.) seeds (grains) exhibit dormancy at maturity that is largely due to the presence of the glumellae (hulls) that reduce the availability of oxygen (O2) to the embryo. In addition, abscisic acid (ABA) and gibberellins (GAS) interact with O2 to regulate barley seed dormancy. A population-based threshold model was applied to quantify the sensitivities of seeds and excised ...

Clostridium sordellii and Clostridium difficile are closely related anaerobic Gram-positive, spore-forming human pathogens. C. sordellii and C. difficile form spores that are believed to be the infectious form of these bacteria. These spores return to toxin-producing vegetative cells upon binding to small molecule germinants. The endogenous compounds that regulate clostridial spore germination ...

Folate deficiency associated with low dietary intake is a well-documented public health problem, resulting in serious health and socioeconomic burdens. Therefore, optimization of the germination process of different cultivars of legume seeds in relation to the content and composition of folate, vitamin C, and total phenolics and total antioxidant capacity was carried out to maximize the health-...

Leukocytes from two patients with chronic granulomatous disease of childhood (CGD) and from one female carrier were examined for their capacity to induce germination of Clostridium botulinum type A spores in vitro. Normal human leukocytes induced germination of C. botulinum spores to the same extent as guinea pig neutrophils. Germination was depressed by more than half when cells from CGD patie...

Germination od three non GMO soybean cultivars: Abelina, SG Anser and Merlin was examined in a laboratory study as affected by pH level: 5.0; 5.5; 6.0; 6.5 7.0. The seeds came from field experiment carried out 2017–2018. Analysis of germination capacity based on two-factor analysis variance completely randomized setting. Among the tested cultivar Abelina had highest capacity. An application 6.0...

this study evaluated direct drilling planters used for wheat cultivation in khorasan-e razavi province. a randomized complete block design with three replications was used. the treatments were direct drilling of wheat plants into wheat residue using the following direct planters: (1) sfoggia (13-25), (2) baldan (spd3000), (3) tondar (spd 2500), (4) semeato (shm 11/13). the parameters measured w...

In the present study, toxic effects of BPA and TBBPA on chickpea seed germination and some possible biochemical changes in the roots were determined. The seed germination did not significantly change in 10 and 50 mg/L BPA and TBBPA applications. However, seed germination was inhibited by 100 mg/L concentration of both treatments. Similarly, chickpea root development was adversely affected by hi...
