Abstract

Twelve trees of both Pinus silvestris L. and Pinus nigra Arold from the region of the "Borino Forestry Station in the West Rhodopes have been tested. The cultivations are situated at a distance of about 2 km apart and though some of the components of the ecological conditions are similar, the two...

AbstractFull Text

The Pseudotsuga menziesii and Pinus nigra plantations were located in the region of Lozen Mts, under equal soil-climatic conditions, but the two studied species show differences in their growth fluctuations. By the means of dendrochronical analysis were revealed the specific reactions of those two...

Abstract

Increment cores were taken from 58 Pinus sylvestris trees in a Bulgarian reserve, and a mean chronology was established covering the period 1802-1992. The smooth sequence of descending and ascending increment phases indicates that these pine ecosystems are developing in a quite stable way, and are...

Abstract

Studies were made of the growth of trees in Picea abies stands on a N. slope and in Pinus sylvestris stands on a S. slope at 1300-1600 m altitude in Bulgaria. Ring chronologies are presented for the two species over the period 1880-1988, and reveal asynchronous patterns, the significance of which...

Abstract

From studies on cores taken from 31 Scots pine trees of Kraft classes I and II in pure stands at 1450-1650 m alt. in Bulgaria, a chronology was established for the period 1804-1986. The chronology showed that growth was consistently high, with a rhythmic pattern caused by the influence of...
