“…On the contrary, the observed decrease in plant height in IT98K-551-1 (Table 6) could be due to debilitating effect of salt on photosynthesis, changes in enzymatic activities and decrease in the level of growth hormones, both of which can lead to inhibition of growth (Mazher et al, 2007). Reports of this finding from the number of leaves was corroborated with the results of Welfare et al (2002) and López-Aguilar et al (2003) with their study on Phaseolus vulgaris L. and V. unguiculata. Their findings revealed that treatment with sodium chloride salt reduced the number of leaves compared with control plants.…”

Abstract. Alternative approach to mitigate the negative consequences of aluminium toxicity on cowpea Vigna unguiculata (L.) Walp. (Fabales: Fabaceae) productivity cannot be overemphasized. The effects of aluminium toxicity on some morphological parameters of five cowpea accessions were investigated with the aim of determining the threshold of tolerance for the crop. Five cowpea accessions were collected from the International Institute of Tropical Agriculture (IITA.), Ibadan, Nigeria. The seedlings were raised in perforated plastic pots filled with 10 kg of top soil and treated till maturity with 50 µm, 100 µm, 200 µm of AlCl 3 while those irrigated with tap water served as the control (0 µm). Variations were observed among accessions and treatments as plant height was accession dependent in contrast to stem girth, number of branches, root growth and shoot growth. Suppression of root growth among the accessions were attributed to more carbon allocation to the shoot at the expense of shoot growth leading to chlorosis, necrosis and reduced photosynthetic capacity among the accessions. Accession 5 was adjudged the best among the accessions based on the response to aluminium treatment. However, further research on the mechanism of tolerance especially at the molecular level is highly recommended.

“…An important strategy for salinity tolerance in highly evolved plants was restricting Na + mobility to prevent Na + from accumulating in the stem and leaf (Lõpez-Aguilar et al 2003). This was demonstrated in this paper with the results that Na + was mainly distributed in the root, and only a small portion was allocated in stem and leaf.…”

Salinity has a great influence on plant growth and distribution. A few existing reports on Artemisia annua L. response to salinity are concentrated on plant growth and artemisinin content; the physiological response and salt damage mitigation are yet to be understood. In this study, the physiological response of varying salt stresses (50, 100, 200, 300, or 400 mM NaCl) on A. annua L. and the effect of exogenous salicylic acid (0.05 or 0.1 mM) at 300-mM salt stress were investigated. Plant growth, antioxidant enzyme activity, proline, and mineral element level were determined. In general, increasing salt concentration significantly reduced plant growth. Superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) were stimulated by salt treatment to a higher enzyme activity in treated plants than those in untreated plants. Content of proline had a visible range of increment in the salt-treated plants. Distribution of mineral elements was in inconformity: Na + and Ca 2+ were mainly accumulated in the roots; K + and Mg 2+ were concentrated in leaves and stems, respectively. Alleviation of growth arrest was observed with exogenous applications of salicylic acid (SA) under salt stress conditions. The activity of SOD and POD was notably enhanced by SA, but the CAT action was suppressed. While exogenous SA had no discernible effect on proline content, it effectively inhibited excessive Na + absorption and promoted Mg 2+ absorption. Ca 2+ and K + contents showed a slight reduction when supplemented with SA. Overall, the positive effect of SA towards resistance to the salinity of A. annua will provide some practical basis for A. annua cultivation.

“…In these stress processes, Na + is the dominant ion causing toxicity, some plant species are also sensitive to Cl − , the major anion in salt‐affected soils (Farooq, Hussain, Wakeel, & Siddique, 2015). Under salinity stress conditions, germination (López‐Aguilar, Orduño‐Cruz, Lucero‐Arce, Murillo‐Amador, & Troyo‐Diéguez, 2003), seedling establishment and growth (Manchanda & Garg, 2008), leaf photosynthesis (Flexas, Bota, Loreto, Cornic, & Sharkey, 2004; Khan, Siddique, Munir, & Colmer, 2015), water and nutrients uptake (Farooq et al., 2015; García, Lucena, Romera, Alcántara, & Pérez‐Vicente, 2010; Okcu, Kaya, & Atak, 2005), biomass accumulation and translocation (Pitann et al., 2011), grain filling (Khan, Siddique, & Colmer, 2016), grain yield, and grain quality of crops (Farshid & Hassan, 2012; Song et al., 2019) can be significantly affected.…”

Salinity is a major abiotic stress limiting crop growth and reducing grain yield. In recent years, little progress was made in salt‐tolerant cultivation techniques. Therefore, a controlled experiment was conducted to study the effects of nitrogen management (NM) on growth, antioxidant ability, and yield performance of salt‐tolerant rice (Oryza sativa L.) under salinity stress. Three salinity levels (0‰ as control; 0.75‰, 4.3 dS m−1; and 1.5‰, 7.7 dS m−1) and four levels of NM (tillering fertilizer/panicle initiation fertilizer = 7:3, 6:4, 5:5, and 4:6) were arranged in this study. Under salinity stress, plant height, tiller number, fresh weight, grain yield, panicle, spikelets per panicle, grain weight, and soluble sugar content in stem were significantly decreased. In contrast, antioxidant parameters of superoxide dismutase, peroxidase, and catalase were significantly increased. Grain filling percentage and sucrose content were slightly changed. Compared to the control, grain yield was reduced by 45.6%, 34.8%, 60.4%, and 46.7% at the ratio of 7:3, 6:4, 5:5, and 4:6 NM at 0.75‰ salinity level, and 73.5%, 59.7%, 74.8%, and 61.7% at 1.5‰ salinity level, respectively. The highest yield was generated by 6:4 NM at both the 0.75‰ and 1.5‰ salinity level, and the lowest by 4:6 and 5:5. However, NM could obviously alleviate the inhibition effects of salinity stress and improve antioxidant ability of rice. Among them, 6:4 NM performed the best alleviation effects, followed by 7:3 and 5:5 NM. This study suggests that the appropriate NM can effectively alleviate salinity stress and increase grain yield.
