Abstract Chloris gayana Kunth is a grass species valuable as forage which was introduced into Argentina to be used as pasture in saline soils of subtropical and warm-temperate zones, given its good adaptability to drought, salinity and mild freezing. However, its tolerance varies according to the cultivar. In tetraploid cultivars, important reductions in yield have been observed. Here, a study of the variations produced on the root and stem system by salinity at different NaCl concentrations (0, 150 y 250 mM) was performed in the Boma cultivar, with the aim of determining the anatomical and morphological alterations produced by the salt… More >

Abstract Pecan [Carya illinoensis (Wanngenh) K. Koch] is one of the most important nut crops in arid and semiarid regions of Mexico. Here, most pecans are grown in saline soils having poor permeability which are further degraded by the use of low-quality irrigation water. Salinity adversely affects both pecan nut quality and yield. Little work has been done to explore the physiological effects of salinity on native pecan trees. Here we examine physiological changes determined by exposure of pecan seedlings to sodium sulfate (Na₂SO₄) at four concentrations: 1000, 2000, 3000 and 4000 mg/L applied twice weekly over a 70 d period.… More >

Abstract Salinity adversely affects physiological and biochemical processes in plants. Plants might have different methods to decrease the harmful effects of salinity, such as the accumulation of osmolytes and antioxidant compounds. An experiment was conducted in the Department of Biological Sciences, University of Sargodha, Pakistan to determine the effect of different levels of phosphorus (P) on wheat under saline conditions. Data of shoot and root fresh and dry weights, chlorophyll contents, different ion accumulation and yield components of wheat were collected. When different levels of phosphorus were applied on wheat plant under saline conditions, phosphorus reduced the effect of salinity. Applications… More >

Abstract Cococarpus lancifolius Engl. grows wild in Djibouti, Somalia and East Africa, and South Asia. The species was introduced into Kuwait, where it is exposed to several stresses: oil pollution, salinity, high temperature and harsh climatic conditions. These conditions are prevalent in its semi-arid environment. In this study, the impact of salinity (2, 6 and 10%), temperature (20, 30 and 40 °C), polyethylene glycol (10, 30 and 60%) and drought has been investigated on C. lancifolius. Proline (Pro) accumulation (5.5 ± 0.03 µg/g dry weight; p≤0.05-0.005), protein (16.47 ± 0.052 mg/g; p≤0.001), free amino acids (10.92 ± 0.082 mg/g; p≤0.006) and… More >

Abstract This paper reports the genotypic variability in the accumulation of proline on the in vitro calli of bean cultivars exposed to induced water and salinity stress. Remarkable variations in the proline content were found among bean cultivars exposed to both stress factors. More >

Abstract Abiotic stresses, such as drought and salinity, adversely affect plant growth and productivity. Comparison between non transgenic and transgenic rice harboring CaMsrB2 gene, which induces tolerance to abiotic stress, is important to observe response of gene under abiotic stress. Phytohormone showed a tendency to increase under the drought stress or salinity stress in the transgenic plant. RT-PCR analysis showed that gene expression and phytohormone levels under abiotic stress, to be closely related. The CaMsrB2 gene is related to the expression of JA and ABA hormones. Therefore, the level of expression of these genes and hormones was observed. The transcription levels… More >

Abstract Soil salinity affects the growth and yield of crops. The stress of soil salinity on plants can be mitigated by inoculation of plant growth promoting bacteria (PGPR). The influence of PGPR inoculation on wheat (Triticum aestivum L.) crop productivity under salinity stress has not been properly addressed so far. Therefore, the present study was conducted to investigate the effects of various PGPR strains (W14, W10 and 6K; alone and combined) at several growth attributes of wheat plant under different soil salinity gradients (3, 6 and 9 dS m-1). The growth attributes of wheat (height, roots, shoots, spikes, grains quality, biological… More >

Abstract Salinity is one of the abiotic stresses that limits the growth and productivity of many crops. A possible survival strategy for plant under saline conditions is to use compounds that could minimize the harmful effects of salt stress on the plant development. The objective of the presented study was to investigate the effect of exogenous ascorbic acid (ASA) with or without gibberellic acid (GA3) on key growth and biochemical parameters in two petunia cultivars ‘Prism Rose’ and ‘Prism White’ under saline (150 mM NaCl) and non-saline in vitro condition. Nodal cutting with an axillary buds were used as explants. Application… More >
