Poor germination and low seedling growth of stevia are common problems in the cultivation of the plant. Nutri-priming is a newest, safe, easy, and effective method to increase germination characteristics and seedling tolerance against stress. The objective in this study was to assess the effect of nutri-priming with nano potassium (nano-K), paclobutrazol (PBZ), and salicylic acid (SA) on stevia...

the effects of environmental factors on germination and emergence of hoary cress seeds were examined in laboratory and field experiments. germinability of hoary cress under light/dark conditions (90%) was significantly higher than when seeds were incubated under continuous dark (78%). hoary cress could germinate in a broad range of temperatures (15/6, 20/10, 25/15, 30/15, and 35/20?c). the germ...

The effects of magnetic fields (MF) on germination and early growth parameters, redox state and the activity of antioxidant system were investigated in soybean (Glycine max L. Merrill) seedlings. The seeds were imbibed in water and then were exposed to a 30 mT static magnetic field (SMF) and a 10 kHz electromagnetic field (EMF) for 4 days, each 5 h. Water uptake of seeds increased after 40 and ...

seed reserves are controlled by genetic and environmental condition such as nutrition, temperature, drought stress and light intensity. strong seedling will produce from seeds with high reserves. therefore, in this work that conducted in pot, field(in tabriz university) and lab(in shahrood university of technology) experiments, effect of pre-anthesis nitrogen application and a drought stress du...

Galactinol synthase (GolS) catalyzes the first and rate limiting step of Raffinose Family Oligosaccharide (RFO) biosynthetic pathway, which is a highly specialized metabolic event in plants. Increased accumulation of galactinol and RFOs in seeds have been reported in few plant species, however their precise role in seed vigor and longevity remain elusive. In present study, we have shown that ga...
