LANDSCAPE STUDIES ON SOME RESORTS GARDENS IN THE WEST NORTH COAST

Abstract

This experiment was carried out during two successive growing seasons of 2019 and 2020 from January to April, on the North coast of Egypt at Marsa Matroh Governorate, Sidi Abd-Alrahman Gulf, 130 km from Alexandria and 193 km from Matroh in a Multinational real estate company resort (Marassi) to examine the extent to which the international compliance obligation is applicable under Egyptian conditions (in the North-Western Coast tourist resorts) as well as studying the new plants used in landscaping and the best standards in the landscape constructions. The experiment was carried out where 108 plants representing 6 plant species were used, each plant variety represented by 18 individuals, then divided the number of plants into two halves, the first one was placed in an open area exposed to winds from all sides without any cover and the second half was placed in an area protected from the direct influence of the winds. The plants of each half were divided into three groups, the first group was cultivated in white sea sand, the second one was cultivated in loamy soils and the third one was cultivated in clean red soil. With reference to the landscape survey at the site, three usual plant varieties were used, namely Nerium oleander, N. oleander 'Petite Salmon' and Bougainvillea sanderiana comparing them with three new varieties, namely, Bougainvillea 'California Gold', Lantana camara and Lantana × money. The experimental layout was designed to provide a split-split plot design containing three replicates. The main plot was the wind exposure, different media represented subplots, while different species were the sub-subplot. Three pots were used as a plot for each treatment. The results of this study showed that the type of soil used, as well as the influence of climatic changes, the most important of which is wind, plays an important role in the morphological characteristics of various ornamental plants in the northern coastal region. The cultivar Bougainvillea 'California Gold' excelled in the different characteristics of plant height, leaf area, number of branches and leaves, and the percentage of chlorophyll in the leaves, under all the conditions used, including the influence of soil and wind types.
