| Abstract: | A reduction in abscisic acid (ABA) content was not a pre-requisite for the breaking of dormancy of vegetative lateral buds
of both field-grown trees and shoots of willow (Salix viminalis L.) maintained in controlled conditions. Similar variations
in bud ABA levels were observed whether the shoots were stored in a warm (22 ± 1 °C) or cold (6 ± 0.5 °C) environment. Following
transfer to a growth room the ABA content of chilled buds declined more rapidly than did that of non-chilled buds. |
