STUDIES ON GROWTH AND DEVELOPMENT OF HEDERA HELIX L. ON DIFFERENT WOODY SPECIES.

The most known spontaneous species of woody climber, common ivy, it was found to prefer some species more then others as host for its growth and development. Different trees and shrubs from the biggest urban park in Bucharest were investigated to find the presence of spontaneous growth of Hedera helix on their trunks and branches. Seven species of trees and three shrubs were labeled as preferred hosts (100% presence) for Hedera helix, no matter their age or health condition, while four species of trees and nine shrubs were found as totally inconvenient (0% presence) for ivy growth. It was concluded that some species of woody plants create better conditions for Hedera helix to grow as an invasive plant, with considerable repercussions on the plantations management programs.
