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...
Evening primrose (Oenothera biennis L.) is native to North America, belongs to Onagraceae family, and is a biennial plant. This experiment was performed as factorial based on a completely randomized design in three replications. The main purpose of the study was to evaluate the effect of moist-chilling and GA</s...
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...

Seeds of seven species of medicinal plants collected from the natural habitat in Lorestan province in summer 2011. Germination test carried out in a completely randomized design with four replications of 25 seeds in H2O. Species of Smyrnium cordifrolium, Kelussia odoratissima, Dorema aucheri and Ferulago angulata had no germination while Heracleum persicum, Bunium luristanicum and Falcaria vulg...
DOR: 98.1000/2383-1251.1398.6.95.11.1.1578.41 Extended Abstract Introduction: White Astragalus (Astragalus gossypinus Fisherr.) is one of the valuable plants for producing gum, which is of critical importance in soil conservation and the economy of the country. This plant is propagated by seed; its seeds are in the natural state of dormancy. Therefore, recognizing the factors affecting dorm...
The seeds of two species (Citrulus colocynthis) and (Silybum mrianum) gathered from natural habitat located in the Koohdasht city (Lorestan province) and transferred to Kermanshah Agricultural and Natural Resources Research and Education Center in the summer of 2014. For each species, separate experiments in a completely randomized design with 14 treatments and 4 replications were done. Treat...
OBJECTIVE To develop a protocol for breaking of seed dormancy and increasing the seed germination rate of Bunium persicum. METHODS The seeds were treated with 3.1, 6.3, 12.5, 25, 50 and 100 µmol/L of benzyl aminopurine, gibberellic acid (GA3), thidiazuron (TDZ) and forchlorfenuron. Then, seeds were transferred to two different temperature conditions including room temperature (25 °C) and chil...
Yellow-cedar (Chamaecyparis nootkatensis [D. Don] Spach) seeds exhibit prolonged coat-imposed dormancy following their dispersal from the parent plant. Analyses were undertaken using S-(+)-[(3)H] abscisic acid (ABA) to monitor the capacity of embryos to metabolize ABA following their isolation from seeds subjected to various dormancy-breaking and control treatments. Radiolabelled phaseic acid (...
henbane hyoscyamus reticulatus l. is a plant species in solanaceae family that seeds hardly germinate because of seed dormancy. in order to determine the best methods for seed dormancy breaking in henbane, a experiment was conducted as a completely randomized design with three replications. the treatments included moist pre-chilling (at 4 °c) for 7, 14, 21 and 28 days, combined treatment of gib...
