The germination niches of grassland species targeted for restoration: effects of seed pre-treatments
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
smirnovia iranica (sabeti) synonym: smirnovia turkestana (bunge) is a deciduous perennial bushy species of the fabaceae (papilionaceae) family. the species grow on sand dunes of desert areas, having a deep vertical root and very long horizontal or lateral roots. they have an important role in natural vegetation of desert and sand dune stabilization. limited growing areas, grazing due to good pa...
The scarcity of surface water has led to the use underground sources as an alternative for crop irrigation by farmers in semi-arid regions. However, these generally have high salinity, which prevents agricultural production. objective this study was determine effects pre-germination treatments with plant growth regulators and bioactivators on melon seeds attenuate salt stress caused during germ...

Cucumber seeds are light-sensitive, dark-germinating seeds. Inhibition of germination can be induced by prolonged exposure to continuous or intermittent FR. The dark germination process and the response to FR are phytochrome controlled. Phytochrome can be detected in these seeds by differential spectrophotometry in vivo. Spectrophotometrically measurable phytochrome increases during dark germin...
Cassia tora seeds, like those of many leguminous species, have hard and impermeable coats. Germination is thought to be enhanced when seeds are scarified or soaked in concentrated sulfuric acid or hot water. This experiment shows the effect of various presown treatments on C. tora with respect to its germination behavior. Germination percentages were significantly affected by different pretreat...
Ferula ovina Boiss. is one of grazing species whose seed germination faces certain problems. The dormancy characteristics of and optimum conditions for seed germination of this species have not been investigated so far. The present research was designed to investigate the effect of GA3 and moist chilling on seed germination of this plant. At first, a factorial the experiment in a completely ran...
