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...

The objective of this study was to evaluate seed metrics, optimum temperature for germination and efficiency five pre-germination treatments overcoming dormancy Caesalpinia ferrea seeds. Seeds were subjected constant temperatures 15, 20, 25, 30 35°C the following treatments: nicking with pincers; immersion in water 24 hours at room temperature; scarification sandpaper; caustic soda 60 minutes; ...

to determine the effects of pre-germinating of tubers and plant density on yield and some agronomic traits of six commercial potato cultivars, an experiment was carried out in ardebil agricultural research station for two years (2001 and 2002). the experiment was in a split split splot on the basis of completely randomized block design with three replications. pre-germination and non pre-germin...

kochia (kochia scoparia l. schard) is an annual, halophyte and drought resistant plant that can be irrigated with saline water and a valuable source for forage under drought and saline ecosystem. in order to evaluate the germination characteristic of kochia under different temperatures and salinity stress levels, an experiment was conducted at physiology lab of ferdowsi university of mashhad, i...

to study the effect of salinity stress on seed germination and seedling growth of four medicinal plants, nigella sativa l., cannabis sativa l., trigonella foenum graecum and cynara scolymus l. an experiment was conducted in the botany laboratory of islamic azad university, birjand branch. a completely randomized design (crd) with 3 replications was used as separately for each species. treatment...

Cold atmospheric plasma treatments have been applied on lenses seeds and shoots to improve their germination and vigor rates. Two approaches have been considered: direct plasma exposure and plasma activation of liquids (tap water, demineralized water and liquid fertilizer). A special focus has been drawn on reactive oxygen species generated in the plasma phase but also in plasma activated media...

Among the most important environmental sensors in plants are the phytochromes, members of a duplicatedgene family of photoreceptors. We characterized the functional diversification of this gene family with respect to a single ecologically important and highly environmentally sensitive process—germination—and thereby addressed the consequence of gene duplication in the evolution of environmental...

The germination behavior of Sporobolus iocladus seeds including germination percentage, accumulated germination percentage, the average incubation period to germination and germination velocity was studied under laboratory conditions. Treatments included six salinity regimes (0, 70, 140, 210, 280 and 350 mM NaCI) and three sources of oil hydrocarbons; Light Arabian Crude, polynuclear aromatic h...

Seed priming has been suggested to improve germination performance under temperature or water stress. The objective of this study was to develop an optimal osmopriming protocol for spinach (Spinacia oleracea L. cv. Bloomsdale) seeds and examine its effect on the germination performance at suboptimal and supraoptimal temperatures, and under water stress. Standard germination tests at optimal ger...
