EVALUATION OF 2+0 AGED NURSERY OF THE SCOTCH PINE (Pinus sylvestrisL.) RAISED IN KASTAMONU-TASKOPRU FOREST NURSERY AS TO TSI QUALITY CLASSIFICATION

Abstract

In this study; 2+0 aged, bare root, Daday-Koldandere origin of Scotch pine seedlings, produced at Kastamonu–Taşköprü forest nursery, were used. First the morphological characters of the seedlings were determined and the appropriateness to TS 2265/February 1988 were examined. Furthermore, the sensitiveness of quality classification both TSI and newly formed for the mentioned scotch pine seedlings were checked with discriminate analysis. In the conclusion, the average values of the seedling height, the root collar diameter, seedling height / root collar diameter ratio, stem dry weight / root dry weight ratio, dry root percent, quality index of 2+0 aged scotch pine seedlings were determined as 11.62 cm, 2.93 mm, 40.14, 2.34, 30.65 %, 0.32 respectively. In addition, 92.7 % of the seedlings as to the seedling height criterion, 98.7 % of the seedlings as to the root collar diameter criterion, 91.4 % of the seedlings as to the seedling height - root collar diameter criterion, 92.7 % of the seedlings as to the stem dry weight / root dry weight ratio criterion were included in first quality class in respect of TSI quality classification.
