The effects of Drought and salinity stress on the growth and chemical compositions pennyroyal(Mentha pulegium L.) plant were investigated. This experiment was carried out in a factorial-randomized design with four replications in controlled conditions and plantlets were subject to four soil moisture regimes (40, 60, 80 and 100 of field capacity (FC)) and five salt treatments with 0, 25...

phytoremediation is an eco-friendly method for removal of pollutants, which can be relied upon as a sustainable technology, if implemented under optimum conditions of plant growth. the effectiveness of water hyacinth, a topical weed, for the removal of zinc (zn) and chromium (cr) ions from aqueous solutions has been presented in this article. the potential of this plant in removing metals by ph...

Salt stress is one of the major factors limiting crop productivity worldwide. Grain amaranth is new crop with high yield potential and good nutrition value which can be a good substitute for salt-sensitive crops in saline areas. This research was conducted to evaluate different level of salinity and applied salinity stress at several growth stages on some morphological and physiological traits ...

abiotic stresses including salinity are the major limiting factors of growth and crop production worldwide. microbial endophytes as the most important soil microorganisms, by modifying plants at genetical, physiological and ecological levels increase their yield per area unit and provide the possibility of crop production in saline and arid soils or climates with biotic and abiotic stresses. th...

drought and salinity are the most important limiting factors of plant growth and development in many regions of the world. in this regard, using of species that are able to have higher production in this condition is a suitable strategy. in order to study the effect of drought and salinity stresses on morphophysiological properties of kallar grass (leptochloa fusca l. kunth), a factorial experi...

The mangrove habitat exhibits many unique physical features, one of the most important of which is a salinity gradient. Photosynthetic rates, as measured by leaf stomatal conductance and leaf chlorophyll fluorescence induction, were tested as indicators of salinity stress in seedlings of the red mangrove, Rhizophora mangle, grown under five different salinity levels: 0, 15, 30, 45, and 60 parts...

Establishing crop cultivars with strong tolerance to P and N deprivation, high salinity, and drought is an effective way to improve crop yield and promote sustainable agriculture worldwide. A vacuolar H+-pyrophosphatase (V-H+-PPase) gene in wheat (TaVP) was functionally characterized in this study. TaVP cDNA is 2586-bp long and encodes a 775-amino-acid polypeptide that contains 10 conserved mem...

Calmodulin-like (CML) proteins are important Ca(2+) sensors, which play significant role in mediating plant stress tolerance. In the present study, cold responsive calmodulin-like (ShCML44) gene was isolated from cold tolerant wild tomato (Solanum habrochaites), and functionally characterized. The ShCML44 was differentially expressed in all plant tissues including root, stem, leaf, flower and f...
