Determination of Relationship with Leaf Area Index (LAI) and Diameter at Breast-Height, Cone Yield, Heritability in Scots Pine Seed Orchard

This study was carried out in Kastamonu Ta？k？prü-Tek？am Sar？？am (Pinus sylvestris L.) clonal seed orchard. In the study, the correlations between the number of cones and tree diameter at breat height (d1,30), leaf area index (LAI) and the clones were inquired, and the heritability ratios (H2) depending on these characters were calculated. As a result of the study, as changes in the number of cones depending on the clones, LAI and tree diameter were examined, it was found that there were significant correlations between the number of cones and LAI as well as clones (p<0.05). No significant correlation was found between the LAI (0.72 - 2.18 m2m-2) and diameter at breat height (14.8 - 30.9cm.) (p>0.05). It has been determined that the cone yield of a tree differs according to the clones (p<0.05). In the study, the heritability values were calculated; the highest heritability value was obtained in the number of H2 cones and the values obtained in LAI were far below the average. The significant correlation between the cone yield and the LAI, which seems to be very important for the clonal seed orchards, shows that the LAI is also a critical factor for the optimization of the seed yield
