Salinity stress is a form of abiotic stress that threatens the sustainability of agriculture in almost all countries in the world. It has an impact in reducing plant productivity. Red amaranth (Amaranthus tricolor L.) is a vegetable crop that has high nutritional value, but extensive saline land area can cause red amaranth yields to decline. Osmopriming is a seed priming method in which seeds are immersed in a solution that has a high osmotic potential, such as PEG (polyethylene glycol) in order to increase germination under unfavorable conditions. This study determined the effect of osmopriming on germination, physiological, and root anatomical attributes of red amaranth roots under salinity stress conditions. The research design used a completely randomized design with two types of treatment, namely, osmopriming and salinity stress. Each treatment used three concentrations, seed osmopriming with 0%, 5%, and 10% of PEG and salinity stress of 0 mM, 50 mM, and 100 mM of NaCl. The measured parameters were germination, growth, physiological, and root anatomical characters. Osmopriming of seeds with 10% PEG increased germination as indicated by the germination percentage, time, and rate reaching 95.55%, 1.393 day, and 71.98%/day, respectively. Red amaranth plants that had been osmoprimed with 10% PEG grew faster when exposed to salinity stress. Application of PEG 5% and 10% increased total chlorophyll levels while decreasing proline levels and Ca-oxalate crystal density. Under salinity stress conditions, PEG application improved the root anatomical characters of red amaranth as shown by increased epidermis thickness, cortex thickness, and stele diameter. Priming application with 10% PEG has the potential to increase the tolerance of red amaranth to salinity stress.

Global climate change induced environmental stress such as salinity significantly impact growth and crop productivity. Red amaranth (Amaranthus tricolor L.) is a vegetable commodity that has high nutritional value, but its productivity will decrease when grown in saline area. Seed priming is one of the pre-planting treatment techniques used to increase plant growth under unfavourable conditions. Osmopriming is one of the priming techniques where the seeds will be immersed in a solution with a high osmotic potential, such as PEG (Polyethylene Glycol). The purpose of this study was to determine the morphophysiological response of red amaranth to osmopriming treatment under salinity stress. Complete randomized design was used to arrange this experiment containing two variables including seed osmopriming (0, 5% and 10% of PEG) and salinity stress (0, 50, and 100 mM of NaCl). Morphophysiological parameters were measured including plant height, number of leaves, root length, leaf chlorophyll content, proline content, oxalic acid content and Ca-oxalate crystal density. After seed osmopriming with 10% of PEG 6000 increased plant height, number of leaves and root length of red amaranth Under salinity stress. Chlorophyll content increased while proline, oxalic acid content and Ca-oxalate crystal density decreased on osmopriming with 10% of PEG 6000. Seed osmopriming enhances morphophysiological characters to overcome problems in cultivating of red amaranth on saline area.

Plants are unable to grow at their full potential under different environmental stress conditions which could lead to decreased crop productivity. To improve the growth of the plants in such situations, application of fertilizers and agrochemicals are employed by the farmers. However, the application of phytohormones is still under exploration. In this context, in the present study, salicylic acid with different doses (5 µM, 10 µM, 20 µM, 50 µM, and 100 µM) have been used for the foliar application at four days intervals three times to grow Amaranthus plants in pot soil under natural weather conditions. Among all the treated plants it was observed that among all the doses, at 10µM SA there was the maximum increase in the total plant length, leaf number, and fresh biomass by 23%, 16%, and 34%, respectively. The values of the chlorophyll fluorescence matrix also showed a beneficial impact of salicylic acid only up to 20 µM of SA. Further, the level of oxidative biomarkers including SOR and MDA reduced up to 20 µM of SA but H2O2 showed an increasing trend in a dose-dependent manner. To counterbalance the oxidative biomarkers, the application of salicylic acid increased the activities of SOD, POD, APX, and elemental uptake (Ca, Mg, Zn) concentration-wise. However, among the different antioxidative enzymes, CAT showed a different trend by decreasing their activities with increasing doses of salicylic acid. Exogenous salicylic acid also reduced the level of oxalic acid and increased the level of endogenous salicylic acid. Therefore, among the different doses, the lower dose particularly the 10 µM showed a better biomass allocation and qualitative attributes over the control plants. This study would provide a sustainable strategy where the appropriate dose of salicylic acid could be applied to support the plant metabolism in the presence of any stress conditions.
