In order to find the most effective method to overcome seed dormancy in Teucrium chamaedrys  L. medicinal plant species the effect of some chemical and physical breaking methods including: cold stratification (5 °C), scarification with sandpaper, stratification with needle, concentrated sulfuric acid, gibberellic acid and combination of these methods were investigated. Treated seeds along with ...

this research aims to evaluate the effects of seed scarification on five perennialastragalus species including a. effusus, a. vegetus, a. subsecundus, a. brevidens and a.cyclophyllon in the field conditions. seeds were sown after scarification with sandpaper byhand in the field of homand absard rangeland research station, damavand, iran in autumnin 2008. the seeds were sown using split plot des...

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...

A major problem affecting the populations of the endangered mission blue butterfly of the northern coast of California is the declining numbers of its host plant, the silver leaf lupine (Lupinus albifrons), due to competition with non-native species. An attempt to ensure the restoration of populations of L. albifrons through germination in greenhouses and subsequent transplantation was initiate...

Background: The aim of this research was to investigate the efficiency methods overcome primary dormancy and biochemical processes associated with germination Erythrina falcata Benth seeds. Seeds were submitted overcoming treatments water uptake pattern analysed. We then evaluated activity antioxidant enzymes SOD, CAT, APX, quantified lipid peroxidation levels, hydrogen peroxide content total p...

ABSTRACT Ormosia grossa Rudd is an Amazonian species that presents bicolor seeds, allowing its exploration for handicraft and decoration making. This paper aimed to analyze the influence of different methods overcome dormancy on germinative performance seeds. To conduct experiment, following treatments were established: T1= scarification with 80-grit sandpaper water immersion at room temperatur...

germination is a critical stage in the life cycle of plants and often controls population dynamics, with major practical implications. salsola arbusculiformis is one of the most important plants used to prevent soil erosion and a good fodder resource for sheep and goat in the rangelands of iran. however, the species seems to have low seed germination, so the purpose of this study was to investi...

Light availability and dormancy are two factors that interfere with germination initial plant growth. This study aimed to evaluate the influence of different pre-germination treatments on emergence growth Euterpe oleracea Mart. seedlings subjected levels luminosity. A completely randomized design was adopted in a 4 × 3 factorial scheme four methods overcoming (intact seed, hot water at 60 °C, s...
