Abstract

Three tree-ring chronologies of white pine (Pinus strobus), a species which are non-native to Europe, were constructed for Suuremoisa, Jadivere and Jarvselja sites in Estonia. These chronologies were related to instrumental climate records and Scots pine (P. sylvestris) chronologies from nearby sites. Growth rates of P. strobus exceeded those of P. sylvestris. The chronologies of the non-native and native pine species relatively well correlated with each other. Moreover, tree-ring growth of both species correlated positively with late-winter and spring (February–May) temperatures and negatively with spring (April) precipitation. While P. strobus growth was positively associated with summer precipitation, the growth of P. sylvestris remained positively related to the growing season temperatures. Both species exhibited a negative growth anomaly from 1939 to 1942. Keywords: Pinus strobus, Pinus sylvestris, dendroclimatology, Estonia

白松和苏格兰松树年轮年表作为爱沙尼亚与气候相关的非本土和本土树木生长模式的指标

在爱沙尼亚的Suuremoisa, Jadivere和Jarvselja遗址建立了三种非欧洲本土物种白松(Pinus strobus)的年轮年表。这些年代学与仪器气候记录和附近遗址的苏格兰松年代学相关。水草的生长速度高于水草。外来松林和本土松林的年代学具有较好的相关性。此外，两种树种的年轮生长与冬末和春季(2 - 5月)气温呈正相关，与春季(4月)降水呈负相关。水杨的生长与夏季降水呈显著正相关，而西林的生长与生长季节温度呈显著正相关。从1939年到1942年，两个物种都表现出负增长异常。关键词:油松，西林松，树木气候学，爱沙尼亚

期刊介绍： The journal welcomes the original articles as well as short reports, review papers on forestry and forest science throughout the Baltic Sea region and elsewhere in the area of boreal and temperate forests. The Baltic Sea region is rather unique through its intrinsic environment and distinguished geographical and social conditions. A temperate climate, transitional and continental, has influenced formation of the mixed coniferous and deciduous stands of high productivity and biological diversity. The forest science has been affected by the ideas from both the East and West. In 1995, Forest Research Institutes and Universities from Estonia, Latvia and Lithuania joined their efforts to publish BALTIC FORESTRY.
