“…One of the changes caused by salt stress in plants is yellowing and drying, starting with tissues such as leaves and the tip of the shoot then spreading to the plant's shoots. These yellowing and drying are symptoms resulting from the breakdown of chloroplasts and chlorophyll (Abid et al, 2020). By making use of these symptoms, it is possible to determine to what extent the plant is affected by salt stress.…”

Ornamental plants are used to improve the aestheticquality of urban and rural landscapes, recreational areas, interiorscapes and commercial sites. Any negative effects of salts on ornamental plant growth have to be taken into consideration mainly for their negative influences on aesthetic value of ornamental plants. The research was conducted to determine the effects of different concentrations of calcium nitrate on some stress parameters (i.e. leaf relative water content, chlorophyll, stomatal conductance, ion leakage in the leaf tissues) and some plant growth parameters (total leaf number, number of dried leaf, main stem diameter, plant crown diameter, plant height, fresh and dry weight of root) of ornamental kale (Brassica oleracea L. var. acephala) plant grown under saline conditions. Four doses of NaCl (NaCl1:30, NaCl2:60, NaCl3:90, NaCl4:120 mM), three doses of Ca(NO3)2 (CaN1:5, CaN2:10, CaN3:15 mM), groups combined together in all doses of NaCl and Ca (NO3)2 and control (NaCl0:0 + CaN0:0) were applied into the pots with three replications. Ca (NO3)2 was applied to the leaf surface of the plants in the pots to be applied as Ca (NO3)2 spray. When the plants reached a certain maturity (two weeks after transfer to the pot), salt stress applications were started. Ca (NO3)2 treatments have applied after one week from salt stress applications. Calcium nitrate treatements applied under salt stress conditions had positive effects and increasing in effect on all parameters examined except for chlorophyll and ion leakage in leaf tissues of the plant. With increasing in calcium nitrate concentration, morphological and physiological characteristics of plants were observed increases in general. It was concluded that the increase of the number of leaves by NaCl2+CaN3 application can be minimized with CaN3 (with 15 mM Ca (NO3)2) stress caused by 60 mM salt concentration According to the results of the research, calcium nitrate applications can be recommended for ornamental kale plants grown under salt stress conditions especially limiting the negative effects of stress and to minimize such damage.

“…In order to cope with different environmental conditions, plants would produce dynamic responses and positive adjustment in their biological characteristics, such as morphological structures, physiological mechanisms and even genetic characteristics [17][18][19]. Changes in plants' morphologies are the most intuitive response to abiotic stress.…”

Broussonetia papyrifera is a widely distributed economic tree species, and it is also a pioneer species in adverse environments. In order to investigate the growth and adaptation mechanism of B. papyrifera under cadmium (Cd) contaminated soil, potted experiments were used with six-month treatments to study Cd enrichment and the transportation, morphological and physiological characteristics of B. papyrifera tissues. The results showed that Cd mainly accumulated in the root when the Cd concentration was high (14.71 mg/kg), and the root biomass was significantly reduced by Cd stress although Cd promoted the growth of seedlings. The bioconcentration factors (BCF) increased with the increase in Cd concentration, and reached the maximum value of 0.21 at 14.71 mg/kg. On the contrary, translocation factor (TF) decreased significantly at 8.28–14.71 mg/kg Cd concentration. Cd not only led to the loose arrangement of the xylem vessels of leaves, but also changed the chlorophyll content. However, B. papyrifera could synthesize organic solutes such as soluble protein, soluble sugar and proline to reduce the intracellular osmotic potential. Our study proved that B. papyrifera has good tolerance to Cd stress and is a pioneer tree species for soil and ecological environment restoration.

“…During their life cycles, higher plants always face environmental stress factors, the most dangerous of which are the shortage of fresh water for irrigation and soil salinity. Deficiency of irrigation water (DiW) and soil salinity stress (SsS) solely or in combination severely affect the growth and productivity of most plant species (Abd El-Mageed et al, 2018;Yang et al, 2019;Abid et al, 2020). As freshwater is the most important resource and a limiting factor for agricultural development, its diminishing availability has become a global problem that requires the development of alternative resources for agricultural use.…”

As an important medicinal plant used in traditional and modern medicine, chili peppers are sensitive or moderately sensitive to drought or salt stress, respectively. Therefore, potential changes due to foliar-applied glutathione (GSH; 0, 0.4 and 0.8 mM) response on growth, yield, and physio-biochemical attributes, as well as water use efficiency (WUE) and fruit alkaloid capsaicin of chili pepper plants were investigated when grown under deficit irrigation in salt-affected soil (EC = 6.74 dS m–1). Two deficit irrigation water (DiW) regimes (80% and 60% of soil field capacity; FC) were used versus 100% of FC as a control. Both DiW treatments negatively affected growth and yield parameters, SPAD chlorophyll index, nutrient status, K+/Na+ ratio, and plant anatomical features. In contrast, osmoprotectants, ascorbate, glutathione, capsaicin, and phenolic contents, as well as WUE were increased in association with higher Na+ and Cl– contents. However, exogenously-applied GSH caused significant increases in the above-mentioned parameters along with an additional increase in osmoprotectants, antioxidants, and capsaicin contents, and a decrease in Na+ and Cl– levels compared to corresponding controls. The highest WUE, growth, and fruit yield responses were recorded at 0.8 mM GSH applied to plants under DiW at 80% FC + salinity (6.74 dS m–1). Therefore, this study suggested the use of leafy-applied GSH at 0.8 mM for satisfactory growth and yield with the highest WUE of chili pepper plants grown under salt-affected conditions with deficit irrigation.
