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...

This study was carried out to investigate the effect of hydropriming on seed germination and seedling growth of five different flower seed species (Antirrhinum, Dahlia, Impatiens, Salvia and Zinnia). Hydropriming (20oC, 24 h), surface dried or dried back afterwards, was found to increase germination percentage, seedling emergence and fresh and dry weight. In all species, the maximum advantage i...

background stem cell transplantation has become as a novel treatment  for end-stage kidney, lung, heart , liver diseases and several hematologic disorders. improved survival of transplant recipients has raised awareness of post-transplant complications. one of these complications is transplant-related osteoporosis. methods  in this manuscript we review prevention methods for transplant-related ...

Salicylic acid (SA) inhibited germination of cocklebur (Xanthium pennsylvanicum Wlr), lower seeds, which are completely after-ripened and nondormant. SA also inhibited ethylene production during a pre-germination period of the seeds. Exogenous ethylene overcame the inhibtion of the seed germination by SA. Moreover, SA reduced respiration in pre-germinating whole seeds as well as excised axial...

Having nursery rapeseed (Brassica napus L.) seedlings at a high density in tray is an indispensable step to realizing mechanized transplanting for rapeseed. The reduction seedling quality caused by sowing one of the key factors affecting and yield. Uniconazole has been considered as potential plant growth regulator improve under diverse unfavorable circumstances. In two densities (400 800 seeds...
