Effect of thawing time, cooling rate and boron nutrition on freezing point of the primordial shoot in Norway spruce buds

BACKGROUND: Effects of cooling rates on bud frost hardiness have been studied but there is little information on bud responses to thawing. Since the cell wall pore size has been found to increase with boron (B) deficiency, B deficiency may affect the supercooling ability of buds in winter. METHODS:...
