Title Response of photosynthetic pigments to drought and salt stress in some desert species
Source Feddes Repertorium
Abstract The effect of drought and NaCl osmotic stress were tested on the pigment contents of the desert species Gymnocarpos decandrum, Ononis vaginalis, Plantago albicans and Zygophyllum album. Samples of these species were collected from their habitats in the north-western desert of Egypt and from plants grown in the green-house under different levels of osmotic stress. The pigment contents decreased with drought stress but increased with salt stress with varying degrees in the four species. Chlorophyll b was more sensitive to drought stress than chlorophyll a. Higher pigment contents were recorded in the widely distributed species than in the less distributed ones. Chlorophyll a, b and carotenoids exhibited higher tolerance to salt stress than to drought.
