introduction: cleome viscose linn. with a common name as “asian spiderflower”, belongs to the capparidacea family. it is an annual, sticky herb found as a common weed all over the tropical regions of the world. it is a very competitive weed of annual crops. this plant is currently introduced as an invasive plant in soybean fields of golestan province. there is no management recommendation to co...

This study was performed to investigate the effect of storage conditions on seed germination performance of faba bean (cv. Shami). For this purpose, a three factors factorial experiment was conducted in laboratory of Seed Science and Technology, Faculty of Agriculture, Yasouj University, in 2013-2014, based on CRD design with five replications.  The experimental factors were storage temperature...

Yunnanopilia longistaminea is an endangered monotypic species belonging to Opiliaceae. This edible plant is an important germplasm source with a high economic value in China if propagation were less difficult. Seed dormancy and germination of this species were investigated to improve propagation. Considering seeds have a fully developed embryo and mature and are dispersed in summer, and radicle...

to evaluate the effects of accelerated aging and cold stress on seed germination and seedling growth indices in five oilseed rape cultivars (hyola330, hyola401, hyola420, syn3 and pr401/15e), an experiment was carried out in a completely randomized design of three replications. results indicated that the cultivars were significantly different in germination percentage, seed vigour, germination ...

Seed dormancy and endozoochorous dispersal have important effects on population dynamics, i.e. seed bank formation, spatial and temporal bethedging, avoidance of crowding and decreased sib-competition. Seeds having primary dormancy do not germinate, even if adequate environmental and dispersal conditions are met, until an after-ripening period is completed. This study examined the effects on ge...

The occurrence of various species of Brassicaceae with indehiscent fruits in the cold deserts of NW China suggests that there are adaptive advantages of this trait. We hypothesized that the pericarp of the single-seeded silicles of Isatis violascens restricts embryo expansion and thus prevents germination for 1 or more years. Thus, our aim was to investigate the role of the pericarp in seed dor...

The success of a biological invasion relies on the environment and is closely linked to factors such as water and temperature. Invasive plant species display different seed characteristics, including shape. Field sandbur (Cenchrus pauciflorus) is a globally widespread invasive species capable of adapting to broad environmental conditions. However, its germination response to water and temperatu...
