“…On the other hand, it was reported by Kumar and Sinha (1995) that in their experiment the same ZEN concentrations as those used in our experiment caused inhibition the elongation of the coleoptile and root in gram and mustard, and this response increased with ZEN concentration. The salt stress strongly limited the growth of seedlings, as was also reported in other papers concerning wheat and soybean (Ashraf and McNeily 1988;Luo et al 2005;Soltani et al 2006). ZEN protected via after-effects the process of wheat growth against the salt stress through decreasing the level of inhibition to the elongation process and mass accumulation in coleoptile and roots.…”

“…For the germinating soybean, Cl -ion is more toxic than Na ? (Luo et al 2005). It seems that the positive effect of ZEN on the intensity of seedling growth at the earlier phases of growth could be explained, among other, by its ability to increase the activity of a-amylase and b-glucosidase (Vianello and Macri 1982).…”

The effect of zearalenone on PSII photochemical activity and growth in wheat and soybean under salt (NaCl) stress

The effects of mycotoxin zearalenone (ZEN) on the photochemical activity of photosystem II (PSII) in wheat and soybean leaf discs incubated in ZEN solutions as well as the after-effects of pre-sowing soaking of seeds in solutions containing ZEN on the photochemical activity of PSII and on the seedlings growth under salt stress (NaCl solutions were investigated). The incubation of wheat leaf discs in ZEN solutions strongly inhibited the energy flux per cross section (CS) for absorption (ABS/CS), trapping (TRo/CS) and electron transport (ETo/CS), while the effects of ZEN action on soybean discs were opposite and the values of those parameters significantly increased with the increase in ZEN concentration. Incubation of seeds in a ZEN solution resulted in an increase in photochemical efficiency of PSII in soybean seedlings, but did not induce any response of PSII in those of wheat at medium illuminations. Only at the stronger illumination for both species did ZEN induce an increase in efficiency of excitation energy capture by open PSII reaction centers, photochemical quenching of chlorophyll a fluorescence and quantum yield of PSII electron transport. Pre-sowing soaking of seeds in a ZEN solution decreased the photoinhibitory injuries of PSII in wheat and soybean due to safe scattering of the excess excitation energy through an increase in energy-dependent quenching (qE) and state transition quenching (qT). ZEN when added to NaCl solutions during the period of germination contributed to reduction in the growth inhibition of wheat seedlings. The incubation of wheat leaf discs in ZEN solutions strongly inhibited CS, ABS/CS, TRo/CS and ETo/CS. Possible effects of ZEN on some physiological processes in plants have been discussed especially in the context with photochemical activity of PSII and a salt stress.

“…Grown under salinity condition for two months, the rate of photosynthesis, leaf area, and plant biomass of G. soja were lower than those of the crop planted in the control treatment (Kao et al, 2006). Other studies showed that G. soja was not sensitive to Cl-toxicity compared to G. max, so it might be possible using G. soja to improve tolerance of G. max to salinity (Luo et al, 2005).…”

The research aimed to determine the tolerance limit of soybean genotypes toward salinity stress, plant growth and physiological characteristics. It was conducted in green house, from April to August 2013. The study involved two activities. The first activity for evaluating a salinity stress, consisted of four levels of soil salinity (EC): 0.9; 4; 7; 10 dS m -1 and eleven genotypes. The second one to obtain information about changes in physiological and morphological characteristics of soybean affected by salinity stress. The second activity consisted of two soil salinity levels (EC): 1.52 dS m -1 and 8.58 dS m -1. The results showed that at salinity 10 dS m -1 , all varieties/genotypes were not able to survive until the age of 43 days after sowing (DAS). At salinity 4 dS m -1 , total plant dry weight of most genotypes soybean decreased by 48.14%, while the salinity of 7 dS m -1 total plant dry weight of all soybean decreased by 64.89%. Concentration of K and Na in soybean leaves were higher than those in soybean root tissue. The content of K and Na in leaves and roots of most soybean genotypes increased as soil salinity increased from 1.52 to 8.58 dS m -1 , except for genotype G11.

Physiological adaptive mechanisms of plants grown in saline soil and implications for sustainable saline agriculture in coastal zone

There is large area of saline abandoned and lowyielding land distributed in coastal zone in the world. Soil salinity which inhibits plant growth and decreases crop yield is a serious and chronic problem for agricultural production. Improving plant salt tolerance is a feasible way to solve this problem. Plant physiological and biochemical responses under salinity stress become a hot issue at present, because it can provide insights into how plants may be modified to become more tolerant. It is generally known that the negative effects of soil salinity on plants are ascribed to ion toxicity, oxidative stress and osmotic stress, and great progress has been made in the study on molecular and physiological mechanisms of plant salinity tolerance in recent years. However, the present knowledge is not easily applied in the agronomy research under field environment. In this review, we simplified the physiological adaptive mechanisms in plants grown in saline soil and put forward a practical procedure for discerning physiological status and responses. In our opinion, this procedure consists of two steps. First, negative effects of salt stress are evaluated by the changes in biomass, crop yield and photosynthesis. Second, the underlying reasons are analyzed from osmotic regulation, antioxidant response and ion homeostasis. Photosynthesis is a good indicator of the harmful effects of saline soil on plants because of its close relation with crop yield and high sensitivity to environmental stress. Particularly, chlorophyll a fluorescence transient has been accepted as a reliable, sensitive and convenient tool in photosynthesis research in recent years, and it can facilitate and enrich photosynthetic research under field environment.
