“…This reduction was also observed by Dalchiavon et al (2016), in studies on the effect of saline stress on common bean seeds (Phaseolus vulgaris L.), where increased saline concentration caused a reduction in root growth, hindering their normal development. In addition, Oliveira and Silva (2019) verified reduction of shoot and root growth of common bean seedlings and decreased fresh and dry seedling biomass even in small salt concentrations (0.1 MPa), demonstrating that this species has low tolerance to salt stress caused by KCl.…”

“…Distinguishing how different plant species react to excess salt exposure is critical as it allows delineating possible salinity control strategies in arid and semi-arid regions, which are constantly more affected by soil salinization processes (Oliveira & Silva 2019). Therefore, this study aimed to evaluate the germination and initial development of common rue subjected to different saline concentrations.…”

Salinization occurring through irrigation on arable land has been a growing concern worldwide. This study aimed to evaluate the germination and initial development of common rue subjected to different saline concentrations. Two salts (sodium chloride and calcium chloride) and five saline concentrations (zero,-0.1,-0.2,-0.3, and-0.4 MPa) were utilized. Germination tests, first germination count, seedling length and dry weight were employed to assess seed responses to the studied variations. Based on the results, the excess of salt reduces the germination percentage and the initial development of common rue seedlings, regardless of the substance used for stress induction.

“…According to Oliveira and Silva (2019), knowing how the different plant species react to salt stress is important because only in this way it is possible to seek mitigating strategies of salinity control in arid and semiarid regions, which are constantly more affected by the processes of soil salinization. While some species survive in soils with high salt concentrations, others are unable to establish in soils with small amounts of salts.…”

Salinity is one of the striking problems in agricultural production in many parts of the world. Seed germination and seedling growth are two critical stages for the establishment of crops generally most sensitive to salt stress. The present study aimed at evaluating the germination and initial growth of pepper seedlings produced from seeds under different soaking times in NaCl solutions. The experiment was carried out in a completely randomized design, in a 2 × 4 × 5 factorial scheme using two pepper species (Capsicum chinense Jacq. and Capsicum frutescens L.), four levels of electrical conductivity (EC) of solutions (1.5, 3.0, 4.5, and 6.0 dS m-1) and five times of seed soaking in the solutions (2, 4, 6, 8 and 10 h), with three replications. The traits evaluated were the number of germinated seedlings, percentage of germination, seedling height, and root length. The results showed that C. frutescens pepper was more tolerant to different times of soaking in saline solutions prepared with NaCl compared to C. chinense. Thus, the results suggest that depending on the pepper species, it is recommended to use seeds primed in saline solutions with salinity levels compatible with those under field conditions (in saline soils and/or irrigation with saline waters).

“…However, potassium excess interfers in other cations absorption (PRADO, 2008;TAIZ et al, 2013), and under high concentrations, it can have a harmful effect on the plant, affecting cell membranes or proteins structures (MELO et al, 2020). The potassium chloride osmotic effects has been noticed, causing plasmolysis, reducing germination (OLIVEIRA et al, 2019), survival and growth and biomass production of plants (MELO et al, 2020).…”

“…Allemão, family Anacardiaceae, are representative of the Caatinga, being widely distributed. L. ferrea is a colonizer of secondary stages (LORENZI, 2008) while M. tenuiflora is a pioneer species (AZEVÊDO et al, 2012), both are used for energy purposes and wood production (CARVALHO, 2003;OLIVEIRA, 2003;LORENZI, 2008), in addition to having medicinal properties (SAMPAIO et al, 2009; OLIVEIRA ALMEIDA, E.

Drought stress negatively influences a variety of essential physiological process for plant growth and biomass production, and potassium contributes to the absorption of water and maintaining cell turgor, being crucial to understand the seedlings water stress responses. This research aimed to verify the effects to water deficiency and potassium on the growth and accumulation of organic solutes in Myracrodruon urundeuva, Libidibia ferrea, and Mimosa tenuiflora. The treatments were distributed in a 3 x 3 factorial scheme, with three water levels (100%pc - control, 50%pc - moderate water deficit, and 25%pc - severe water deficit) and three doses of potassium (0, 97.5 and 195 mg dm-3 K). The plants were sown in black plastic bags, containing 5 kg of soil. Were evaluated plant height, stem diameter, and leaf concentrations of total soluble sugars, total free amino acids, and proteins. The water deficit caused a reduction in the growth of M. urundeuva and M. tenuiflora plants, regardless of the added potassium. The plants of M. urundeuva and M. tenuiflora were not demanding in potassium, while potassium fertilization with 97.5 mg dm-3 K favored L. ferrea plants, especially when kept under moderate water deficit. The moderate water deficit promoted accumulation of total free amino acids and soluble proteins in M. urundeuva, while in L. ferrea there was accumulation of total free amino acids under severe water deficit. Increase in the potassium promoted reduction in the concentrations of total soluble sugars and soluble proteins.
