OBTAINING AN ANNUAL VARIETAL CONVEYER OF ORNAMENTAL SHRUBS FOR THE PARKS OF THE PRE-CARPATHIAN AREA OF MUNTENIA

Abstract

To provide a longer ornamental life of the dendrological park at Research Institute for Fruit Growing Pitesti-Maracineni, Arges, a wider range of species and varieties well adjusted to soil and climate conditions in the area was employed. The studies were performed at the RIFG within 1977-2006 period. The observation and measurements were alone on the ornamental plants of the park-collection. There were observed 132 species and valuable ornamental varieties. Studies were focused on decoration of the dendrological park with valuable ornamental plants. Introduction. Ornamental species are a group of shrub plants or climbing plants whose main utility is their decorative feature. The ornamental spectrum is given by the shape of shrub and leaves, as well as by the colour of branches, leaves, flowers and fruits, by the preservation period of fruits on the plant, and especially by the leaves persistence during winter time in the sempervirescente species. Due to this great ornamental variation, these species can play various roles in the familiar parks and gardens. Compared to the ornamental trees and fruit trees, the ornamental shrubs are basic elements for small-area parks and gardens around the houses, commercial companies, villas and even platforms and balconies. The purpose of this paper was to: 1) show the development of the vegetative and generative phenophases, 2) describe the plants and emphasize the strong scenery elements, 3) obtain a varietal conveyer in the green areas for a period as long as possible, 4) present the behaviour of the ornamental species and varieties under the specific soil and climate conditions of the region as well as under the pollutant factors of the environment.
