Summary

Agriculture is vital for the survival of modern civilizations, but soil and climate disturbances increasingly hinder the excellent performance of crops. Abiotic stresses such as drought, salinity, and climate change cause significant crop losses. These stresses often act together and must be studied with greater scientific rigor.

This special issue focuses on developing and evaluating strategies for developing agricultural crops subject to abiotic stresses. For this reason, it welcomes interdisciplinary studies from research fields related to agriculture, including Horticulture, Genetics, Plant Ecophysiology, Irrigation, Soils, and Plant Nutrition. Research articles will cover various agricultural scenarios in different regions of the world. Original research articles and reviews will be accepted.

Chen Xu, Tianhao Luan, Zexin Qi, Xiaolong Liu, Yaliang Liu, Hui Sun, Yueqiao Li, Ning Sun, Qian Li, Shaofeng Bian, Lihua Zhang, Hongxiang Zhao
Phyton-International Journal of Experimental Botany, Vol.94, No.11, pp. 3703-3719, 2025, DOI:10.32604/phyton.2025.071324

Abstract Optimizing drip irrigation with straw mulch return represents a promising sustainable intensification strategy for revolutionizing regional water management. This 2-year controlled field experiment examined straw incorporation effects (removal and return) and drip irrigation levels (200, 350, 500 mm) on maize carbon-nitrogen metabolism, root bleeding sap characteristics, dry matter accumulation, and yield. Dry matter and yield increased with irrigation amount. Under 200–350 mm irrigation, straw return enhanced root bleeding intensity; elevated nitrogen, phosphorus, potassium, calcium, and magnesium concentrations in bleeding sap; and promoted soluble sugar and hydrolyzed amino acid contents, establishing material foundations for yield formation.

Abstract Due to its tolerance to water deficit and salinity, sorghum is considered a suitable crop for cultivation in regions affected by these stress conditions, enabling the efficient use of limited water resources. This study evaluated the resilience of the sweet sorghum cultivar BRS 506 under water deficit and salinity stress, focusing on water relations and yield performance in semiarid conditions. A randomized complete block design was employed in a 3 × 3 factorial arrangement with four replicates. Treatments consisted of three levels of irrigation water salinity (1.50, 3.75, and 6.00 dS m⁻¹) and three irrigation levels… More >

Evaluation of Seaweeds as Stimulators to Alleviate Salinity-Induced Stress on Some Agronomic Traits of Different Peanut (Arachis hypogaea L.) Cultivars
Nilüfer Kocak Sahin
Phyton-International Journal of Experimental Botany, Vol.94, No.8, pp. 2399-2421, 2025, DOI:10.32604/phyton.2025.067880
（This article belongs to the Special Issue: Abiotic Stress in Agricultural Crops)
Abstract Peanut (Arachis hypogaea) is of international importance as a source of oil and protein. Soil salinity is one of the most significant abiotic stress factors affecting the yield and quality of peanuts. This study evaluated the potential of a seaweed-based biostimulant to enhance emergence and seedling growth of four peanut cultivars (‘Ayse Hanım’, ‘Halis Bey’, ‘NC-7’, and ‘Albenek’) under increasing salinity levels. The experiment was conducted under greenhouse conditions using a randomized complete block design with four replicates. Seeds were sown in trays and treated with two doses of seaweed extract (0 and 5 g L⁻¹) applied… More >

Effects of Drought Stress on the Physiological Characteristics of Flue-Cured Tobacco during the Vigorous Growing Period
Kesu Wei, Guangju Liu, Bin Wei, Qifang Zhang, Shengjiang Wu, Zhaowei Li
Phyton-International Journal of Experimental Botany, Vol.94, No.4, pp. 1287-1298, 2025, DOI:10.32604/phyton.2025.062385
（This article belongs to the Special Issue: Abiotic Stress in Agricultural Crops)
Abstract To systematically examine the tolerance of flue-cured tobacco K326 to soil drought stress, this study set up different water content trials for K326 at 60%, 40%, and 20% levels during the vigorous growing period by greenhouse pot planting. Pigment content, chlorophyll fluorescence parameters, antioxidant enzyme activity, and SPS and GS activities associated with carbon and nitrogen metabolism were investigated in the K326 tobacco leaves. The results showed that chlorophyll a and chlorophyll b contents decreased, non-photochemical quenching coefficient Y(NPQ) decreased in the later stage of vigorous growth, and energy dissipation quantum yield Y(NO) levels increased… More >

Enhancing Salt Stress Tolerance in Portulaca oleracea L. Using Ascophyllum nodosum Biostimulant
Zahra Alhawsa, Rewaa Jalal, Nouf Asiri
Phyton-International Journal of Experimental Botany, Vol.94, No.4, pp. 1319-1337, 2025, DOI:10.32604/phyton.2025.061918
（This article belongs to the Special Issue: Abiotic Stress in Agricultural Crops)
Abstract Salinity stress is a major constraint on agricultural productivity, particularly in arid and semi-arid regions. This study evaluated the potential of Ascophyllum nodosum extract (ANE) in mitigating salinity-induced stress and enhancing the growth and physiological performance of Portulaca oleracea L. under NaCl concentrations of 0, 50, 70, and 100 mM for 50 days. A two-way ANOVA assessed the effects of NaCl concentration, ANE treatment, and their interaction. The results showed that ANE significantly increased plant height at 50 mM NaCl (p = 0.0011) but had no effect at higher salinity levels (p > 0.05). Shoot dry weight was… More >

Blanca Olivia Trejo-Paniagua, Nancy Ruiz-Lau, María Goretty Caamal-Chan, Rosa Isela Cruz-Rodríguez, Anayancy Lam-Gutiérrez, Víctor Manuel Ruíz-Valdiviezo
Phyton-International Journal of Experimental Botany, Vol.94, No.3, pp. 861-873, 2025, DOI:10.32604/phyton.2025.062410
（This article belongs to the Special Issue: Abiotic Stress in Agricultural Crops)
Abstract Exogenous proline is an effective agent for increasing plant tolerance to abiotic stress in plants. In this study, we evaluated its effect on seedlings of Siete Caldos chili pepper (Capsicum frutescens), a semi-domesticated variety. The Capsicum genus is known for its sensitivity to water stress. We pretreated the seedlings’ roots by immersing them in proline solutions (0, 2.5, 5, 7.5, and 10 mM) for 48 h. Then, we exposed them to water stress using a Hoagland nutrient solution supplemented with 10% polyethylene glycol (PEG-8000) for nine days. We analyzed key physiological and biochemical parameters, including relative… More >

Assessing Stress Tolerance of SUBI and DRO1 Introgression Lines under Flooding and Drought Conditions at Different Growth Stages
Ibrahim Soe, Emmanuel Odama, Alex Tamu, Aquilino Lado Legge Wani, Taiichiro Ookawa, Abdelbagi M. Ismail, Jun-Ichi Sakagami
Phyton-International Journal of Experimental Botany, Vol.94, No.2, pp. 303-316, 2025, DOI:10.32604/phyton.2025.060016
（This article belongs to the Special Issue: Abiotic Stress in Agricultural Crops)
Abstract Rice varieties tolerant to submergence regulate shoot elongation during short-term submergence by expressing the SUB1A gene. In contrast, the deep-rooted DRO1 is effectively expressed under drought conditions to enhance water and nutrient uptake. This study investigates the growth and yield of rice with both SUB1A and DRO1 in the background of IR64, under early-season flooding, and mid-season drought. The study used a randomized complete design with two factors: soil moisture treatments (submergence, drought, and their combination) and genotypes. The genotypes included IR64, and three near-isogenic lines (NILs): NIL-SUB1DRO1, NIL-SUB1, and NIL-DRO1. Complete submergence was imposed for 7… More >
