Dynamic shifts in climatic patterns increase soil salinity and boron levels, which are the major abiotic factors that affect plant growth secondary metabolism. The present study assessed role of regulators, including biochar (5 g kg–1) gallic acid (GA, 2 mM), altering leaf morpho-anatomical physiological responses Solanum melongena L. exposed to (25 mg stresses (150 mM NaCl). These regulators enhanced fresh weight (LFW) (70%), dry (LDW) (20%), area (LA), index (LAI) (85%), moisture content (LMC) (98%), relative water (RWC) (115%) under stresses. Physiological attributes were analyzed determine stress levels antioxidant protection.

Abstract Micronutrient application has a crucial role in mitigating salinity stress crop plants. This study was carried out to investigate the effect of zinc (Zn) and boron (B) as foliar applications on fenugreek growth physiology under salt (0 120 mM). After 35 days treatments, three levels (0, 50, 100 ppm) two 2 were applied application. Salinity significantly reduced root length (72.7%) shoot (33.9%), plant height (36%), leaf area (37%), fresh weight (48%) (75%), dry (80%) (67%), photosynthetic pigments (78%), number branches (50%), seeds per pod (56%). Fenugreek’s improved by spray boron, which increased (6%) (2%), (18%), (8%), chlorophyll (1%), b (25%), total soluble protein content (3%), calcium (9%) potassium (5%) contents decreasing sodium ion (11%) content.

Abstract Pakistan is the 8th most climate-affected country in globe along with a semi-arid to arid climate, thereby crops require higher irrigation from underground water. Moreover, ~ 70% of pumped groundwater irrigated agriculture brackish and major cause secondary salinization. Cucumber ( Cucumis sativus L.) an important vegetable crop annual growth rate about 3.3% Pakistan. However, it relatively salt-sensitive crop. Therefore, dire need for alternate environment-friendly technology like grafting managing salinity stress cucumber by utilizing indigenous cucurbit landraces.

Climatic changes have a direct negative impact on the growth, development, and productivity of crops. The water potential (ψ) temperature (T) are important limiting factors that influence rate seed germination growth indices. To examine how responds to in temperature, hydrotime model hydrothermal (HTT) been employed. HTT calculates concept time across temperatures, between Tb-To, with alteration, Tb-Tc, supra-optimal ranges. seeds Cucumis melo L. were germinated laboratory for hydro-thermal experiment. Seeds sown Petri dishes containing double-layered filter paper at different osmotic potentials (0, -0.2, -0.4, -0.6, -0.8 MPa) by providing PEG 6000 (drought stress enhancer) temperatures (15, 20, 25, 30, 35 °C). controlled replicate was treated 10 mL distilled rest solution. Results indicated vigor index (SVI-II) highest 15 °C 0 MPa lowest 30 -0.2 MPa. However, activity shown catalase (CAT) guaiacol peroxidase (GPX) (-0.6 MPa), while values CAT GPX recorded control °C, respectively. Germination energy positively correlated (GI), percentage (G%), index, index-I (SVI-I), mean moisture content (MMC), root shoot ratio (RSR) had correlation rate, percent root, CAT, superoxide dismutase, ascorbate peroxidase, GPX. In conclusion, thermal models correctly predicted muskmelon response varying temperature. agronomic attributes found be maximum minimum °C.

Climatic change and extreme weather events have become a major threat to global agricultural productivity. Plants coexist with microorganisms, which play significant role in influencing their growth functional traits. The rhizosphere serves as an ecological niche encompassing plant roots is chemically complex environment that supports the development of diverse plant-interactive microbes. Although plant-microbe interactions been extensively investigated however, limited exploration made how abiotic stresses affect structure assembly microbial communities rhizosphere. This review highlights climate influence on growth, traits, communities. It explores mechanisms for mitigating stress, such removing reactive oxygen species (ROS), regulating antioxidant activity indole-3-acetic acid (IAA) production, controlling growth-inhibitory ethylene levels through colonization by bacteria producing ACC deaminase. Additionally, we elaborated systematic communicatory network steered hormonal crosstalk root exudation, can modulate initiate dialogues between plants surrounding ultimately promotes chemotactic movement microbes towards rhizosphere, facilitating early colonization. Finally, reviewed recent advancements understanding foster resilience under stress.
