Osmoconditioning of Soybean Seeds to Improve Performance at Suboptimal Temperatures 1

摘要: The use of osmotic treatment or osmoconditioning (OC) to improve the performance soybeans (Glycine (L.) Merrill cv. ‘Traverse’) was explored. aim this investigation examine in detail optimum conditions needed for OC soybean seeds germination and soil emergence at suboptimal temperatures. Such a study is necessary if are be planted early season when moist cold. Osmotic consisted treating with various concentrations polyethylene glycol-6000 (PEG) solutions 15 C. Following treatment, were germinated either on filter paper soaked water medium. improved as shown by axvancement time an increase rate temperatures (8 C). period 06 C range 4 8 days, most favorable PEG concentration 25 30 g/100 ml (−8.6 −11.9 bars). OC, drying original air dry weight did not remove advantage gained OC. Although 0.20/, thiram added solution appearance seedling, it affect These studies suggest that might possible plant osmoconditioned moist, cold extend planting Season and/or uniformity seedling stand.
