“…Because all the treatments were applied as foliar spray, low concentrations were selected based on previous studies (Ahmad et al 2016;Amin et al 2013;Bakhtavar et al 2015;Kamran et al 2016;Kaya et al 2013). The sorghum plants were harvested at maturity, dried, chaffed with a fodder cutter into 2-cm pieces, and stored under shade.…”

Chilling stress hampers the optimal performance of maize under field conditions precipitously by inducing oxidative stress. To confer the damaging effects of chilling stress, the present study aimed to investigate the effects of some natural and synthetic plant growth regulators, i.e., salicylic acid (SA), thiourea (TU), sorghum water extract (SWE), and moringa leaf extract (MLE) on chilling stress tolerance in autumn maize hybrid. Foliar application of growth regulators at low concentrations was carried out at six leaf (V6) and tasseling stages. An increase in crop growth rate (CGR), leaf area index (LAI), leaf area duration (LAD), plant height (PH), grain yield (GY), and total dry matter accumulation (TDM) was observed in exogenously applied plants as compared to control. In addition, improved physio-biochemical, phenological, and grain nutritional quality attributes were noticed in foliar-treated maize plots as compared to non-treated ones. SA-treated plants reduced 20% electrolyte leakage in cell membrane against control. MLE and SA were proved best in improving total phenolic, relative water (19-23%), and chlorophyll contents among other applications. A similar trend was found for photosynthetic and transpiration rates, whereas MLE and SWE were found better in improving CGR, LAI, LAD, TDM, PH, GY, grains per cob, 1000 grain weight, and biological yield among all treatments including control. TU and MLE have significantly reduced the duration in phenological events of crop at the reproductive stage. MLE, TU, and SA also improved the grain protein, oil, and starch contents as compared to control. Enhanced crop water productivity was also observed in MLE-treated plants. Economic analysis suggested that MLE and SA applications were more economical in inducing chilling stress tolerance under field conditions. Although eliciting behavior of all growth regulators improved morpho-physiological attributes against suboptimal temperature stress conditions, MLE and SA acted as leading agents which proved to be better stress alleviators by improving plant physio-biochemical attributes and maize growth.

Soil moisture shortage can reduce yield of waxy corn because maize is one of the sensitive crops to the drought stress. Farmers cannot irrigate due to limited water resource and irrigating facilities although applying water is the most effective practice to solve the drought problem. The study was conducted to investigate the pre-treatment effect of salicylic acid on reducing drought damage of waxy corn (Zea mays L.). Salicylic acid at concentration of 0.2 mM was applied at seven-leaf stage or ten-leaf stage three times. Drought stress was imposed by withholding irrigation from 11 days before anthesis to 10 days after anthesis. Application of salicylic acid significantly increased ear length by 11.0~12.3% and yield by 8.8~11.3% compared with non-treated control, indicating that the drought injuries of waxy corn can be alleviated through pre-treatment of salicylic acid at the vegetative stage.Key words: Drought stress, Salicylic acid, Waxy cornYield of waxy corn treated by foliar application of salicylic acid (SA). SA1 and SA2 denote pre-treatment of salicylic acid at 7-leaf and 10-leaf stage, respectively. Error bars indicate standard deviation.

Abstract:In nature, plants are continuously exposed to solar light. They cannot avoid exposure to UV-B radiation. The purpose of this investigation was to examine how UV-B radiation affects seed germination, seedling growth, protein and sugar contents and activities of antioxidant enzymes in pea (Pisum sativum) seedlings. Salicylic acid mediated physiological responses in UV-B stressed pea seedlings. UV-B exposure adversely affected germination and physiology of Pisum sativum L. Salicylic acid mitigated the impacts of UV-B stress. Seed germination decreased with increased duration of UV-B exposure. Enhanced activities of antioxidant enzymes in response to UV-B radiation played a protective role against UV-B radiation.
