Turkish Journal of Botany
Halopeplis perfoliata, a succulent halophyte of coastal marshy habitats, was grown in a greenhouse to study its adaptive responses in terms of growth, osmoregulation, and N-metabolism following one-month exposure to salinity (0, 150, 300, and 600 mmol L-1 NaCl). Biomass was optimal in 150 mmol L-1 NaCl with unaltered malondialdehyde (MDA) levels. On the other hand, biomass remained comparable to non-saline control with some increase in MDA in 300 and 600 mmol L-1 NaCl. Osmotic potential (?S ) was maintained up to 300 mmol L-1 NaCl that correlated with an increase in succulence (SC) and lower water deficit (WD), whereas …

Ranking Of 11 Coastal Halophytes From Salt Marshes In Northwest Turkey According Their Salt Tolerance, Christian Zörb, Ali̇ Sümer, Ali̇ Sungur, Timothy J. Flowers, Hasan Özcan
Turkish Journal of Botany
Salt-affected soils with high electrolyte contents limit the development of the majority of plants and serve as a habitat only for such species (halophytes) that can survive the conditions. To date, there is still much that is unknown about the physiological mechanisms, including ion relationships, that make plants salt-resistant. The primary aim of this study was to evaluate a method of ranking plants for their salt tolerance. A total of 11 coastal halophytes of the Kavak Delta were evaluated for their ability to cope with different soil salinities. For this, electrical conductivities of soils (of up to 135 dS m^{-1}) …

Ecophysiology Of The Holoparasitic Angiosperm Cistanche Phelypaea (Orobancaceae) In A Coastal Salt Marsh, Gamal Mohammad Fahmy
Turkish Journal of Botany
Cistanche phelypaea (L.) Cout. (Orobancaceae) was found parasitising the roots of the succulent shrublets Arthrocnemum macrostachyum (Moric.) K.Koch (Chenopodiaceae) in a coastal salt marsh in Qatar. Measurements were conducted to identify soil properties, host, and noninfected plants by soil excavations to expose the haustoria of the parasite attached to the host roots. The water potential, osmotic potential, pressure potential, and chemical analyses were determined in parasite, host, and noninfected plants. Crown diameter and dry mass of the host plants were smaller than in the noninfected plants. A gradient of water potential existed between the host root and the underground tuberous …
