Drying of P i n u s p i n e a L. in the Tree Lined Streets in Split Area Summary The authors investigate the reasons of drying of Pinus pinea L. in the tree — lined streets in Split area. The trees were planted in Maksima Gorkog Street, Splitskog odreda Street, Maslešina Street and Oslobođenja Street in the period between 1971 and 1975. The investigations were carried out in 1985. The soil was analysed, the dendrometry measures of the trees were carried out, the growth of the root system was observed. The investigations and the results show that the causes of drying are the disproportion between the upper and the underground part of the trees, which was caused by unfavourable soli for the growth of roots, too great reduction of the crown and wrong planting (deep planting). |
