Investigation on relationship between tree rings of Cupressus sempervirens l . var . horizantalis and climatic variables

During 2008, a severe deluge in Sari caused huge damages and Cupressus sempervirens l. var. horizantalis trees in botany garden of Natural Sciences College were also fallen by the overflow. To perform the study the fallen trees disks and cores of standing trees were prepared. Using Lintab Measuremen...
