The Comparisons Between Root Collar Diameter and Height Growth of Black Pine (Pinus nigra Arnold.) and Scots Pine (Pinus sylvestris L.) Seedlings in Bolu Forest Nursery

Abstract

In this study, root collar diameter and height growth of bare rooted and containerized Black pine seedlings at 1+0 and 2+0 ages were statistically compared to Scots pine seedlings in Bolu forest nursery. Root collar diameters and height growths of 240 seedlings were measured. The obtained data were compared via “Student’s t – test”. Results show that containerized seedlings of both Black pine and Scots pine had a better root collar diameter and height growth than the bare rooted seedlings. Black pine seedlings had a better growth of both collar diameter and height growth than Scots pine for both containerized and bare rooted
seedlings. Thus, containerized seedlings could be used for plantation. Black pine could be preferred rather than Scots pine in areas which have similar climatic and edaphic conditions of the sample area.
