Abstract
This study was conducted on two experiments during two consecutive seasons in 2019 and 2020 in the period from January to April in the northern coast region of Egypt, Marsa Matrouh Governorate, Sidi Abdel Rahman.
- The aim of the first experiment was to study the extent of adaptation of the new plant varieties to the environmental conditions in the northern coast compared to the old varieties of the same species.
- The aim of the second experiment was to enumerate the cultivated plants and their adaptation to the environmental conditions in the northwest coast, in addition to listing the standard specifications used in establishing some gardens.
The first experiment was carried out, where 324 plants were used, then the number of plants was divided into half in an open area. It is exposed to the winds from all sides without any cover and placing the second half in an area protected from the direct influence of the winds. The plants were divided into three sections, the first section was cultivated in white sea sand, the second section was cultivated in loamy soil, and the third section was cultivated in clean red soil. Referring to the plant species survey used at the site, three new plant species were used in Marassi Resort, namely Nerium oleander “Petite Salmon”, Bougainvillea sanderiana and Lantana x money. and comparing them to three commonly used cultivars, Nerium oleander, Bougainvillea ’California Gold’, and Lantana camara. The statistical design used is split plots, and the effect of winds and soil types was placed as the main plots, and the items used in the split plots were placed in three replications. The measured traits included, plant height (cm), plant spread (cm), number of leaves/plant, number of branches/plant, leaf area (cm2), and total chlorophyll percentage in leaves. Data recorded for the measured characters included; plant height (cm), plant spread (cm), number of leaves/ plant, number of branches/ plant, leaf area (cm2) and leaves total chlorophyll (SPAD). The results of the present investigation could be summarized as follows: 1. Plant height: - The wind had a significant effect on plant height, as the tallest plants were recorded in the area directly exposed to winds in both seasons.
- The soil types as there were non significant differences between red soil and loamy soil, and the highest plant height was from white sea sand in both seasons.
- The cultivars had a clear effect on plant height, the cultivar showed that Nerium oleander and Bougainvillea ’California Gold’, resulted in the tallest plants, while the cultivar Lantana x money were the shortest plants in both seasons.
- The plants in open wind grown in white sea sand soil were taller in both seasons.
- The effect of the interaction between different plant types and the wind, was significant, the tallest plants were the cultivar Bougainvillea ’California Gold’ cultivated in the open wind, while the cultivar Lantana x money of the newest cultivars recorded the shortest in open wind, and in area protected from wind as recorded in both seasons.
- The Bougainvillea ’California Gold’ with white sea sand and recorded the tallest plants in the two season, and in red soil in first season, and while the new cultivar 96 Lantana x money recorded the shortest plants in all soil types used in both successive seasons.
- The cultivar Bougainvillea ’California Gold’ recorded tallest plants in the two studied seasons, in all types of soil used under the influence of open wind, the Nerium oleander recorded the tallest plants in second season in red soil with open air, while the cultivar Lantana x money recorded the shortest plants in all soil types used under open air.
- The interaction between the different species with area protected from wind with different soils, Bougainvillea ’California Gold’ cultivar recorded the tallest plant in the white and loamy soils in the two studied soils, while the cultivar Nerium oleander ’Petite Salmon’ recorded the tallest plants in the red soil in both seasons.
