The distribution and dynamics of plant populations depend on the recruitment of young individuals, which is influenced by seed production, animal seed dispersal, dispersal distance, and the deposition of seeds in favourable places for seed germination/ establishment and seedling survival. In particular, seeds dispersed over long distances will likely encounter new environmental conditions that ...

MUT, Z. and H. AKAY, 2010. Effect of seed size and drought stress on germination and seedling growth of naked oat (Avena sativa L.). Bulg. J. Agric. Sci., 16: 459-467 Effects of seed size and osmotic stress on germination and seedling growth of five naked oat genotypes were investigated in this study. Oat genotypes were Mozart, CROA 60, Detvan, Eva 1 and AC Belmont. Small, medium and large seed...

Birds are important seed dispersers for fleshy fruits through their transportation of ingested seeds. The seeds of many species germinate faster and in greater proportions after passing through a digestive tract, although the effects of this passage vary amongst bird and plant species. Many factors determine the germination success of ingested seeds, such as seed scarification during the digest...

Plant growth promoting rhizobacteria (PGPRs) are a group of bacteria that can actively colonize plant roots and can modulate plant growth. The present study was aimed to investigate the effects of three PGPRs strains designated as Pseudomonas fluorescens (PF23) and P. putida (PP-41 and PP-159) on seed germination features including germination percentage (GP), mean time germination (MTG), germi...

The effect of salinity level and extended exposure to different salinity and flooding conditions on germination patterns of three salt-marsh clonal growth plants (Juncus subulatus, Scirpus litoralis, and S. maritimus) was studied. Seed exposure to extended flooding and saline conditions significantly affected the outcome of the germination process in a different, though predictable, way for eac...

Anoectochilus roxburghii (Wall.) Lindl. (Orchidaceae) is an endangered medicinal plant in China, also called "King Medicine". Due to lacking of sufficient nutrients in dust-like seeds, orchid species depend on mycorrhizal fungi for seed germination in the wild. As part of a conservation plan for the species, research on seed germination is necessary. However, the molecular mechanism of seed ger...

Sci., 19: 572-577 Marshmallow (Althea officinalis) is one of the important medicinal plants in Serbia. one of the bigest problem in growing of marshmallow is poor seeds germination. rhyzospheric bacteri...

Dormancy is an adaptive trait that enables seed germination to coincide with favorable environmental conditions. It has been clearly demonstrated that dormancy is induced by abscisic acid (ABA) during seed development on the mother plant. After seed dispersal, germination is preceded by a decline in ABA in imbibed seeds, which results from ABA catabolism through 8'-hydroxylation. The hormonal b...

Parental conditions, such as temperature, soil moisture, nutrient availability, light and competition during plant growth and seed maturation, influence seed quality and germinability. Elevated CO2 concentration can be also treated as a parental condition and should be considered when evaluating crop productivity under future climate conditions. Available information on the effect of parental C...

BACKGROUND AND AIMS The duration of the plant life cycle is an important attribute that determines fitness and coexistence of weeds in arable fields. It depends on the timing of two key life-history traits: time from seed dispersal to germination and time from germination to flowering. These traits are components of the time to reproduction. Dormancy results in reduced and delayed germination, ...
