“…These phytohormones have been used to ameliorate the adverse effects of salinity stress on plant growth and productivity in various plant species (Nimir et al, 2015). Using potassium nitrate (KNO3) for seed-priming treatment showed beneficial effects on plant growth and the production of a wide range of plant species under limited growth conditions (Zanotti et al, 2013). Kinetin (Ki) is a growth regulator that falls under the cytokinins (CK) group, which regulates cell division, apical chloroplast biogenesis, nutrient mobilization, and shoot differentiation (Davies, 2010).…”

To study the effects of salt stress and plant growth regulators (kinetin, gibberellic acid, potassium) on growth, yield, glycine betaine content, phosphoenolpyruvate carboxylase (PEPC) and ribulose biphosphate carboxylase (RBC) gene expression of two Libyan bread wheat varieties, a factorial design of greenhouse experiment with three replications was conducted. Results revealed that salt stress significantly reduced plant growth and productivity of both varieties. Moreover, the addition of kinetin + potassium and gibberellic acid + potassium had improved the performance of the morpho-metric parameters of both genotypes under salt stress; but the performance was more effective for kinetin treatment than for gibberellic acid. At the biochemical level, the results showed that salt stress increased glycine betaine contents in both varieties with different proportions. This increase is more elevated in the presence of kinetin + potassium than the treatment with gibberellic acid+ potassium, which showed an almost similar result as in only salt stress. At the molecular level, the effects of salt stress and plant growth regulators on the PEPC and RBC gene expression showed that the increase was significantly higher for kinetin, gibberellic acid, and salt stress when compared to the control.

“…In recent years, it has become clear that NO has a key role in plant defense signaling under stress conditions, such as high salinity (Zanotti et al, 2013), UV-B radiation (Gupta et al, 2011) and, especially, water deficit (Cho et al, 2013).…”

Seed priming with sodium nitroprusside attenuates the effects of water deficit on soybean seedlings

Considering that water deficit is one of the main environmental factors responsible for low soybean yield and that nitric oxide (NO) has been shown to be a fundamental part of plant defense signaling during stress, the aim of the present study was to evaluate the effect of seed priming with nitric oxide on the induction of water deficit tolerance during the initial development of soybean. Thus, seeds were treated with 0 (water only), 50, 100 or 250 μmol.L-1 sodium nitroprusside for 6 hours. Additionally, untreated seeds were used. After drying, the seeds were placed in containers filled with a commercial substrate mixture and vermiculite and irrigated to 100% and 50% field capacity. Biometric and biochemical evaluations (pigment and proline contents) were performed after 14 days. It was concluded that pretreatment of soybean seeds with 50 to 250 μmol.L-1 SNP attenuated the effects of water deficit on stem growth, leaf area, and shoot dry matter and induced carotenoid biosynthesis. The accumulation of proline in the leaves was pronounced in the treatments with 100 and 250 μmol.L-1 SNP, while 100 μmol.L-1 SNP induced proline accumulation in the roots.

Seeds of Moringa oleifera were planted in sandy and vermicular soil (1/2 w/w) and irrigated with Hoagland solution. Two weeks later, the seedlings were divided into three groups: The first group was irrigated with a control solution (Hoagland solution), the second with a salt solution (10 g/l NaCl) and the third group with a mixed solution (10 g/l NaCl and 100 mM citric acid (CA)). Salinity induced a substantial inhibitory effect on seedling growth of Moringa oleifera. Salt treatment reduced shoot fresh weight (FW), the content of photosynthetic pigments and total soluble proteins (SP). Furthermore, salt treatment resulted in accumulation of total free amino acids, soluble sugars and proline. CA supply in saline solution improved shoot growth, and photosynthetic pigment and soluble proteins levels. The important content of citric acid in leaves was accompanied with a decrease of total free amino acids, soluble sugar and proline contents. More that, exogenous application of citric acid led to a decrease of Malondialdehyde (MDA) and hydrogen peroxide (H2O2) accumulation, reflecting the reduction in the imbalance situation and membrane damage induced by salt stress. Alternatively, citric acid supply in saline conditions reduced the rise of superoxidase dismutase (SOD) and catalase (CAT) activities induced under salinity. Citric acid enhanced the growth rate of salt-treated Moringa oleifera via enhancing antioxidant function. Consequently, citric acid treatment may be a promising method for improving Moringa oleifera plants’ tolerance to salt stress.
