The experimental results herein reported are a summary of thirty years' work in the breeding for cold hardy apples. The cold hardi-ness of apple is shown to be quantitative inheritance. The mean in the first generation hybrids on cold hardiness is much stronger than the value of mid-parents,because of the high transmission of cold hardiness from the parent of hardy crab apple, which is near of a little above the mean of mid-parents in the second generation.

Zhejiang, situated on the north part of citrus distribution, is one of the major citrus-growing provinces of China. The citrus groves are usually suffered by the attact of winter freeze in some districts. Hence, an investigation on how to divide the climate zones related to citrus winter-hardiness is very necessary.According to the cold-hardiness of satsuma orange (citrus unshiu),the data of the ultimate minimum temperature of the nearest twenty years and its related data, the conditions of citrus freeze injuries, divided four climatic regions for satsumas orange in this province, namely. I , no-injury, II , light-injury, III, moderate-injury and IV, heavy-injury. Within these regions, we again divide them into nine sub-regions according to landform and water conditions.Region I and II situated on the east-south coast and south part of the Zhejiang province, are the most suitable districts for citrus-growing. Beside tangerines (citrus reticulata) e. g. satsumas orange, oranges (C.sinensis) can be cultivated in region I In region III, we should select carefully the local microclimate for citrus-growing to avoid winter injury. And, in geneal, it is not recommended to grow citrus trees in region IV .

本文根据温州蜜柑的耐寒性和最近20年的极端最低气温及其有关数据,参考柑桔冻害实况等因素,将浙江省划分为温册蜜柑无冻、轻冻、中冻和重冻四区,再根据地形和低温频率,划分为九个付区。 浙江东南沿海和浙南是温州蜜柑无冻或轻冻区,可以重点发展宽皮桔如温州蜜柑,并适当发展甜橙;在温州蜜柑中冻区发展柑桔要慎重。要注意小气候的利用和重视抗寒防冻;在温州蜜柑重冻区不宜发展。

Apple varieties with different cold-hardiness were studied using elec-trical resistance method, electrical conductance method and direct mea-surement method, and the results were compared. All the above-men-tioned methods gave similar results, but the electrical resistance method gave a wider range of reading values than the other two and proved to be easier and more convenient to manipulate.

对抗寒力不同的苹果品种,用电阻法与直接测定法、电导法进行了对比鉴定,其结果基本一致。但电阻法比直接测定法具有较大的数字幅度,比电导法较为简便适用。 研究了果树枝条R值与温度之间的变化关系,建立了“R图式”。根据“R图式”,论证了鉴定品种抗寒力的适宜范围:在果树生长期为“R图式”的负指数方程区,即在-8~-11℃条件下冷冻处理10小时;在休眠期为细胞膜致害临界点温度以后及负指数方程区,即在-15~-40℃条件下冷冻处理40小时。 对果树不同的生长时期、冷冻温度和冷冻时间等处理,共重复40余次,结果均表现为抗寒力越强R值越大,因此,可根据R值的大小判定果树的抗寒力。处理时期,以休眠期较好,适温幅度大,易于操作。
