in this study, the effects of different concentrations of bulk and nano-sized ag on seed germination and seedling growth of canola were investigated in a randomized completely design with four replications. the experimental treatments included four concentrations of bulk agno 3 (10, 100, 500 and 1000 ppm), four concentrations of nanosized ag (10, 100, 500 and 1000 ppm), and the control without ...

Johar (Cassia siamea Lamk) seeds have physical dormancy, because the entry of water and gases prevents by hard seed coat in process germination. Therefore, to assist germination process, pre treatment form scarification is needed, among others using sulfuric acid (H2SO4) solution. This study aims analyze effect soaking H2SO4 with 96% concentration on johar The used a completely randomized desig...

Pre-dispersal seed predation can greatly reduce crop size affecting recruitment success. In addition, non-fatal damage by seed predators may allow infection by fungi responsible for post-dispersal seed losses. The objectives of this study were (1) to quantify pre-dispersal seed predation and fungal infection in a Neotropical tree species, Luehea seemannii, that produces dehiscent fruits and win...

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...

Vine-leaved kitaibelia (Kitaibela vitifolia Willd.), also known as balkanmalva or chalice flower, is a critically endangered plant species with high risk of extinction in the wild. A reason given for this is, among others, low germination rate primarily caused by dormancy. The present study evaluated seed and seedling growth parameters vine-leaved response to eight different pre-sowing treatmen...

Mine tailings represent a serious threat to the environment and human health; thus their restoration has become a major concern. In this study, the interactions between Brassica juncea and different mine soil treatments were evaluated in order to understand their effect on germination and early growth. Three soil treatments containing 25% and 50% of technosol and 30% of compost were prepared. G...

to study the effects of chilling on dormancy breaking and the increased germination characteristics of nepeta (germination percent and speed, seedling length, vigor index, wet and dry weight), a factorial experiment in a completely randomized design with 4 replications was implemented in a laboratory in 2014. factor a was the chilling treatment in three levels (control, one-month and two-month ...

milk thistle (silybum marianum l. gaertner) is an annual or biannual plant of the asteraceae family. this species is important not only as a medicinal plant traditionally, but also as an endemic plant to protect vegetative and natural resources in iran. this experiment was carried out to find the most effective treatments to break milk thistle seed dormancy and improve its cultivation in vast s...

Orthodox seeds may present ditTerences in germination due to severa] reasons. Poor seed germination Iimits the use of different species for culture or p]ant breeding. In this work, we tested treatments for improving germination in two cultivars of common eggplant (Solanum melongena) and in six accessions of the related species S. macrocarpon, S. aethiopicum, and S. incanum. With the exception o...
