Kelussia odoratissima Mozaff. belonging to the Apiaceae family, is well known for its medicinal and nutritional importance, endemic to Iran. Seed dormancy is a major problem present in Kelussia odoratissima leading to low germination percentage; thus, improvement of seed germination and breaking seed dormancy is important. Piriformospora indica, a root-colonizing endo...

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...

Abstract. Seeds or plant organs are usually used as the materials for the long-term cryopreservation. The aim of this study is to investigate the possibility of seed cryopreservation of Lilium ledebourii (Baker) Boiss. as an endemic and endangered species because of genetic erosion. To evaluate seed potentials for the cryopreservation, four treatments including vitrification, 30% glycerol, desi...

environmental stresses, such as salinity can play an important role in disturbing different stages of plant growth, development, and especially seed germination in arid and semiarid regions in iran. turf grasses are highly dissipation in areas associated with saline soils and/or saline irrigation water. in order to study the effects of salinity on turf grasses germination, an experiment was con...

To study the effect of production region and seed size on germination indices and heterotrophic growth components of peanut seedling, a study was performed in three peanut fields in Astaneh Ashrafieh and Agronomy Laboratory of Rasht Islamic Azad University from 2010 to 2012. This research was carried out using the standard germination, cold and accelerated aging tests. Tests were performed usin...

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 effect of electromagnetic field was examined on zinnia (zinnia elegans) seeds to enhance seed germination and early growth. the seeds were exposed to four magnetic strengths of 15, 100, 400 and 800 mt in four durations of 30, 60, 120 and 240 min. the experiments were carried out in two forms of laboratory germination and soil emergence. results showed that magnetic field application enhance...

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 ...

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 ...

In this paper, the effect of irrigation water salinity levels on seed germination, dry matter weight of seedlings at eight-leave stage, and the salt tolerance of 8 rapeseed cultivars was investigated. Relative yield reduction in saline and non saline conditions, salt sensitivity index and Van Genuchten-Hoffman methods were used to determine the salt tolerance of the cultivars. Results showed th...
