在新斯科舍商业栽培的9个苹果品种中,伏花皮、Wayne和君袖对1980年12月的低温最敏感。冻害发生在第一主枝下的主干和主枝的枝杈部位,在摘除死皮及其邻近未剥落的组织后,树体受害程度十分明显。报导了健康组织受害的百分率,并用一系列照片加以图解说明。在根颈及其以下的根砧部位未发现冻害。 Among nine apple cultivars commercialized in Nova Scotia, Wayne and Wayne were the most sensitive to the December 1980 hypothermia. Frost damage occurred in the main branches of the first main branch and main branches of the twigs and branches. After removal of the dead skin and its adjacent unscraped tissue, the degree of tree damage is very obvious. The percentage of health organizations affected is reported and illustrated by a series of photos. No frost damage was found on the root neck and below.
