Abstract

The research aimed to determine the start, end and duration of leafing phases, the degree of plant damage caused by late spring frost, and the retention of leaves in autumn. The research was conducted in the international common beech provenance test in Bosnia and Herzegovina. The test contains eight provenances from Bosnia and Herzegovina, four from Germany, three from Serbia, two each from Croatia, Romania and Switzerland, and one from Hungary. Leafing phenology, canopy damage caused by late spring frost, and leaf retention were assessed in 2019. Most provenances started opening buds on 17 April 2019. Complete canopy damage affected the highest percentage of plants in provenance BW Bad Wildbad, Germany (68 %), and the lowest in provenance Konjuh Kladanj, Bosnia and Herzegovina (3.2 %). Provenance Herzogenbuchsee from Switzerland had the highest percentage of winter leaf retention (37.5 % of plants). The results can be used in choosing provenances that are resistant to low temperatures in zones of late spring and early autumn frost.
波斯尼亚和黑塞哥维那国际种源试验中普通山毛榉的表型变异性和对晚春霜冻的抗性
研究的目的是确定叶片阶段的开始、结束和持续时间,晚春霜冻对植株的损害程度,以及秋季叶片的保留。该研究是在波斯尼亚和黑塞哥维那的国际山毛榉种源试验中进行的。该测试包含八个来自波斯尼亚和黑塞哥维那的来源,四个来自德国,三个来自塞尔维亚,克罗地亚,罗马尼亚和瑞士各两个,还有一个来自匈牙利。2019年对叶片物候、晚春霜冻对冠层的损害和叶片滞留进行了评估。大多数种源于2019年4月17日开始发芽。德国BW Bad Wildbad种源林冠完全破坏比例最高(68%),波黑Konjuh Kladanj种源林冠完全破坏比例最低(3.2%)。来自瑞士的种源Herzogenbuchsee的冬季叶片保留率最高(37.5%)。研究结果可用于选择春末秋初霜冻地区耐低温的种源。
