Abstract
reductions in plant height, stem diameter, number of leaves and inflorescences 'with saline water treatments, the decreases were in proportion to the increase in salinity level. Also, the data indicated that plants of cv. Red Buttiana and cv. White Buttiana in the first and second seasons, respectively were the tallest. Plants. of cv. Gold Buttiana had the thickest stems in the two seasons. Whereas, plants of cv. White Buttiana showed the highest number of branches and inflorescences. Red Buttiana CII. had the highest number of leaves and the heaviest F.W. of leaves.
All saline water treatments decreased the content of chlorophyll a and b .Red Buttiana cv. in the first season and White Buttiana cv. in the second one contained the highest value of chlorophyll a and b. Growing plants under salinity stress of 1500, 3000, and 4500 ppm, markedly increased the caroteniods content. Most of the saline water treatments caused a remarkable increase in the proline content over the control plants. Red Buttiana cv. in the first season and Gold Buttiana cv. in the second one, had the highest value of pronne content, whereas, the lowest value in both seasons, was recorded with plants of, cv. White Buttiana. In both seasons the N , P, Na, Ca, K and CI percent of leaves and stems of the three bougainvIllea cultivars decreased as salinity level increased.
In conclusion, comparing the values of vegetative growth, flowering and chemical constituents of the three cultivars of bougainvillea plants, the data obtained indicate that White Buttiana CII. in both seasons were the tallest, and had the highest number of branches and inflorescences, the heaviest dry weight of stems, the lowest content of proline, sodium., calcium, and chloride and the highest content of Nand P, as compared with Gold Buttiana and Red Buttiana CIIS.
