Abstract
Flower buds of peach (Prunus persica Batsch) and apple (Malus domestica Borkh.) leached with water for 6 hours were less cold-hardy than nonleached buds. Buds which were leached with water for 16 hours and then dried for 0 to 16 hours were equally damaged by freezing; however, their moisture content decreased as drying time increased. Cold-hardiness was reduced rapidly during the first 3 hours of leaching, then loss of hardiness slowed and remained nearly constant through up to 48 hours of leaching. Loss of hardiness appears to be closely associated with leaching of water-soluble compounds from the flower bud, a loss which reduces the bud's ability to supercool.
