in this study, the effect of nano-silver (ag) treatment on the drying rate and final moisture gradient of poplar wood was investigated. poplar (populous nigra) boards with green dimensions of 100×70×50 and 20 mm were treated with nano-silver (ag) suspension by spraying and immersion method. two concentrations of nano-silver suspension, including 20 and 100 ppm were used. then, the boards were c...

Knowledge on gene action and trait expression are important for effective breeding. The objective of this study was to determine the general combining ability (GCA), specific combining ability (SCA), maternal effects and heritability of drought tolerance, yield and yield components of candidate sweetpotato clones. Twelve genotypes selected for their high yield, dry matter content or drought tol...
