Ameliorative Effect of Foliar Nutrient Supply on Growth, Inorganic Ions, Membrane Permeability, and Leaf Relative Water Content of Physalis Plants under Salinity Stress

Abstract

The effects of nutrients foliarly applied at varying doses were investigated on some agrophysiological properties, such as dry matter, nutrient content, chlorophyll content, membrane permeability, and leaf relative water content, of physalis (Physalis ixocarpa) plants under salinity stress. Plant shoot fresh weight, dry weight, plant length, and chlorophyll contents were reduced by 54.0-61. 8%, 53.4-64.8%, 38.3-47.0%, and 26.5-40.0%, respectively, at 60 and 120 mM (without foliar application) compared to the nonsaline treatment [0 mM sodium chloride (NaCl)]. However, the membrane permeability (MP) of the plants increased with increasing salinity. Ion balance in plant cells is very important to plant growth and tolerance of salinity. So, foliar application alleviates to some extent the deleterious effects of salinity stress on growth and growth parameters, depending on nutrient concentration in plant. The greatest mitigating effects of foliar fertilizer for chlorophyll, shoot fresh weight, leaf relative water content, and MP at high-salinity-stress conditions (60 and 120 mM) were obtained from a 10-mM foliar magnesium nitrate [Mg(NO 3 ) 2 ] application at the ratios 57.2-62. 6%, respectively, ) 2 ] application was most effective for plant shoot dry weight and plant height at 60 and 120 mM salinity stress conditions. These results support the view that supplementary Mg(NO 3 ) 2 and Ca(NO 3 ) 2 application can overcome the effects of high salinity on plant growth and growth parameters under saline conditions.

Effect of Salt Stress on Growth and Metabolite Profiles of Cape Gooseberry (Physalis peruviana L.) along Three Growth Stages

“…In the present study, the vegetative stage (209) did not show an effect associated with a response to salinity conditions for any of the estimated growth parameters. It is possible that Ca 2+ supplementation during fertilization helped to alleviate the inhibitory effect of salt on growth at this stage, as reported in other species of the genus Physalis and cotton plants [ 47 , 48 ]. However, in the case of the higher stages, such supplementation appeared to be insufficient due to the salt accumulation in the substrate.…”

“…The effect of salt stress on growth of Physalis , using high salt concentrations (>60 mM NaCl), was investigated in previous studies, and an inverse effect between salt concentration and plant growth was found [ 50 ]. In other words, higher salt concentrations promoted a lower plant growth since the dry and fresh weight of shoots and plant length were found to be reduced [ 48 ]. In this study, a significant reduction in aerial and root length was observed in the high salinity treatment (i.e., 90 mM) compared to the control.…”

Natural soil biotin application activates soil beneficial microorganisms to improve the thermotolerance of Chinese cabbage

“…Compared to the control group pretreated with purified water, the NSBS pretreatment group exhibited significantly lower relative conductivity and MDA content in leaves after 24 h of heat exposure ( Figure 6 ). Relative conductivity and MDA are important indexes to measure the thermotolerance of plants, which can reflect the changes in membrane permeability of plants under abiotic stress, to indirectly evaluate the strength of stress resistance of plants ( Esringü et al, 2011 ; Liang et al, 2022 ). MDA accumulation reflects the degree of lipid peroxidation, which is a damaging process in plant cells.…”

Zinc and iron-mediated alleviation water deficiency of maize by modulating antioxidant metabolism

“…At the end of the imbibition period, leaf samples were placed in a preheated oven at 80 °C for 48 h to determine dry weight (DW). Values of FW, TW, and DW were used to calculate LRWC using the following equation (Turan et al, 2011).…”
