We have developed an approach combining physiology and quantitative genetics to enhance our understanding of nitrogen (N) metabolism during kernel germination. The physiological study highlighted the central role of glutamine (Gln) synthetase (GS) and Gln synthesis during this developmental process because a concomitant increase of both the enzyme activity and the amino acid content was observe...
Giant foxtail (Setaria faberi) seeds differ in requirements for germination. Variable germinability arises during seed development under the influence of genotype, environment and parent plant. Giant foxtail seed germination has been shown to be regulated by independent asynchronous or dependent synchronous action of seed structures. To gain better insight into the process, germination was divi...
(How and why to measure the germination process?). In the last two centuries, papers have been published including measurements of the germination process. High diversity of mathematical expressions has made comparisons between papers and some times the interpretation of results difficult. Thus, in this paper is included a review about measurements of the germination process, with an analysis o...
22 The impact of Bacillus weihenstephanensis KBAB4 sporulation temperature 23 history was assessed on spore heat resistance, germination and outgrowth capacity at a 24 temperature range from 7 to 30°C. Sporulation rate and efficiency decreased at low 25 temperature, as cells sporulated at 12, 20 and 30°C with approximately 99% 26 efficiency, whereas at 7°C and 10°C, a maximum 15% of sporulation...
Raffinose family oligosaccharides (RFOs), which include raffinose and stachyose, are thought to be an important source of energy during seed germination. In contrast to their potential for promoting germination, RFOs represent anti-nutritional units for monogastric animals when consumed as a component of feed. The exact role for RFOs during soybean seed development and germination has not been ...
Seed germination is sensitive to glucose (Glc), nitric oxide (NO) and polyamine (PA). To elucidate whether cross-talk among Glc, NO and PAs occurs in mediation of seed germination, effects of Glc, NO and spermine on seed germination of Lotus japonicus were studied. Glc retarded seed germination in a concentration-dependent manner. NO donor sodium nitroprusside (SNP) alleviated Glc-induced inhib...
The present investigation attempted to assess the impact of seed pre-treatments on the germination of Crotalaria persica (Burm. f.) Merr and Tephrosia apollinea (L) Pers. Equally important was our investigation to quantitatively compare different germination parameters used for seed germination studies. The results showed that the final germination was highest for both species under chipping (C...
This paper presents evidence that plant brassinosteroid (BR) hormones play a role in promoting germination. It has long been recognized that seed dormancy and germination are regulated by the plant hormones abscisic acid (ABA) and gibberellin (GA). These two hormones act antagonistically with each other. ABA induces seed dormancy in maturing embryos and inhibits germination of seeds. GA breaks ...
DOR: 98.1000/2383-1251.1398.6.145.11.1.1575.1610 Extended Abstract Introduction: Agriculture has been influenced by different abiotic stresses such as temperature, drought and salinity, which reduces roughly half of the yield of crops. In many forage plants, germination and early seedling growth are the most sensitive stages of their growth in the face of environmental stresses. Current r...
Due to the side effects of chemical drugs, the use of medicinal plants has increased in recent years. In this study, in order to select suitable medicinal plants for planting in the soil of Fars Science and Research Branch of Islamic Azad University, the seed germination characteristics of twenty medical plants were examined. These germination parameters include germination percentage, germinat...
