this study was conducted to investigate the effects of different temperatures on seed germination of plantago ovata and also to evaluate cardinal temperatures. various constant temperatures (5, 10, 15, 20, 25, 30 and 35ºc) were conducted in a completely randomized design with four replications. the germinated seeds were counted every day and the rate of germination percentage, cumulative germin...

current research on effect of increasing concentrations (0 (control), 100, 200, 300, 400 and 500 mm) of different salts including nacl and na2so4 on germination and initial growth phase of halostachys caspica were studied. the experimental design was completely randomized design with three replications. characters of percentage, speed and index of germination, seed healthy index, radicle, plumu...

Abstract The germination characteristics response for some selected maize hybrids and their parental inbred lines were observed evaluated in an vitro trial. aim of the study was to determine differences within performance hybridization pathways. Single cross (SC), double (DC) three-way (TC) studied. results showed that seeds started after third day completely germinated on seventh sowing. Hybri...

The germination of Ferula ovina seeds faces certain problems. The present research was designed to study the promotion of the germination of Ferula ovina seeds by moist-chilling and GA3 applications. The results showed that Ferula ovina seeds display an endogenous dormancy that can be released by moist-chilling treatment for a certain period. In this respect, the best treatment was moist-chilli...

Mutation induction is considered as an effective way to enrich plant genetic variation, particularly for traits with a very low level of genetic variation. The objectives of this study were to evaluate the effect of different dosages of chemical mutagens on seed germination, seed viability and seedling growth characteristics and to identify optimum treatment conditions for chemical mutagens bas...

this study was carried out in order to determine the effects of boron and cold stress on pollen germination of almond hybrids in vitro culture, two different media including the absence and presence of boron (0 mg/l, and 100 mg/l) in 10% sucrose and 1% agar medium at 24°c in dark conditions. the results showed that different treatments had a significant effect on the germination percentage. the...

ABSTRACT: Seed priming was used in wheat seeds to increase germination characteristics and tolerance on stress exposure. Wheat seeds were treated with salicylic acid and gibberellin. After 8 days our results showed that, seed priming treatments significantly (p≤ 0.01) affected germination percentage, normality seedling percentage, germination index and seedling length. Seed priming with salicyl...

important cut flowers in tropical and sub tropical areas of the world and has the seventh rate of production between all cut flowers of Iran. In order to investigate different effects of storage temperatures (8 weeks at 4 °C, 4 weeks at 4 °C + 4 weeks at 20 °C, 8 weeks at 12 °C, 4 weeks at 12 °C+ 4 weeks at 20 °C and 8 week at 20 °C) and different concentrations of gibberellic acid (0, 150 and ...
