English title: The relations between main and short shoots of Scots pine.

Abstract

The number of short shoots and the quality of the shoots and needles in 19 shoots of 15 Scots pine (Pinus sylvestris L.) was measured. Usually Scots pine short shoots have two needles. Three-needle short shoots were found in all sample shoots but one. They were most common in fast-growing trees and the shoots in the main stem. One-needle short shoots were relatively rare. In most cases the second needle had withered. The length of the needles was 19‒80 mm, and most common lengths were 30‒50 mm. The width of the needles was in average 0.5‒1.94 mm. There was correlation between the length of the shoot and the length of the needles.
