Effect of Soil Salinity on the Lipid Composition of Halophyte Plants from the Sand Bar of Pomorie

چکیده
Seven samples of halophyte plants (Bassia hirsuta Aschers, Euphorbia peplis L., Salicornia europeae L., Calystegia soldanella, Calystegia sepium, Stachys maritima Gonan and Suaeda maritima Dumort,) were collected from a sand bar near the town of Pomorie (Bulgaria). The soil salinity ranged between 650 and 850 mg salts in 100 g soil. For comparison, two other samples from the species Calistegia sepium were collected also from soils with lower salinities (330 and 90 mg salts in 100 g soil) in different regions of Bulgaria. The results showed almost a linear increase of linoleic/linolenic acid ratio with increasing soil salinity.

The effects of salinity on growth, water relations, glycinebetaine content, and ion accumulation in the perennial halophyte Atriplex griffithii var. stocksii were determined. The following questions were addressed: (1) What effect does salinity have on growth responses at different ages? (2) Is A. griffithii an ion accumulator? (3) Does A. griffithii accumulate glycinebetaine in response to sal...
متن کاملThe effect of plant growth promoting potentials of rhizosphere bacteria isolated from several halophytic species on vegetative growth and ionic content of wheat
Salinity stress is an important challenge for wheat production in the world. Plant growth promoting rhizosphere bacteria, isolated from halophytic plants, can increase the tolerance of crop plants to salinity by direct and indirect mechanisms. In this study, plant growth-promoting traits of bacterial strains (Bacillus safensis, Bacillus pumilus and Zhihengliuella halotolerans), isolated from th...
متن کاملEffect of salinity on growth, ion content and water status of glasswort (Salicornia herbacea L.)
Salinity is one of the major environmental stresses that limit plant growth and productivity. Glasswort (Salicornia herbacea L.) is one of the native halophytic plants of Iran that widely spread in salt areas. The purpose of this study was to determine the physiological and growth responses of S. herbacea to salinity stress. Plastic pods (15 cm diameter, 20 cm height) with the Silica sand bed w...

Saline soils and halophytic vegetations are common features and part of the habitat pattern in deserts and steppes. The saline area is developing in arid lands. Investigation effects of halophytes on soil characteristics and adaptive mechanisms of the various halophyte types is essential for controlling saline environments. Juncus gerardi is a perennial grass-like halophyte and Halocnemum strob...

Plants may induce small-scale heterogeneity in soil nutrients, forming fertile islands. However, this process may depend on plant spices, plant developmental stages and habitat conditions. Vegetation cover in arid and semi-arid regions is mostly in the form of plant patches and bare soil of inter-patch areas, this form of vegetation cover can be useful to study plants impact on soil to get appl...
