Influence of Maternal Habitat on Salt Tolerance During Germination and Growth in Zygophyllum coccineum.

摘要: Zygophyllum coccineum is a facultative halophyte widely distributed in desert wadis and coastal areas Egypt. Here, we investigated the influences of maternal habitat on tolerance to salt stress during germination seedling growth under salinity (0, 100, 200, 400 mM NaCl) three populations Z. from saline (Manzala coast) non-saline habitats (Wadi Houf Wadi Asyuti). In all populations, seed started within two days distilled water but indices were reduced significantly with level increase. Germination percentage was not greater for seeds than those moderate (100, 200 NaCl), only able germinate high (400 NaCl). recovery compared populations. At level, Manzala population showed lowest inhibition shoot length leaf area (200 habitats. same context, had maximum chlorophyll content, superoxide dismutase esterase activities non-significant effect b between Carotenoids enhanced increase levels These results suggest derived adaptive plasticity this species may play an important role wide distribution coccineum.
