“…Cold stress leads to chlorosis, necrosis, changes in cytoplasm viscosity, membrane damage, and changes in enzyme activities leading to plant death (Atayee and Noori, 2020). Moreover, cold stress disrupts the integrity of intracellular organelles, leading to the loss of compartmentalization, reduction and impairment of photosynthesis, protein assembly, and general metabolic processes (Bera et al, 2022). The effects of cold stress cause great challenges to the utilization of overseeded cool-season turfgrasses globally (Xie et al, 2020).…”

Overseeded perennial ryegrass (Lolium perenne L.) turf on dormant bermudagrass (Cynodon dactylon Pers. L) in transitional climatic zones (TCZ) experience a severe reduction in its growth due to cold stress. Primary plant nutrients play an important role in the cold stress tolerance of plants. To better understand the cold stress tolerance of overseeded perennial ryegrass under TCZ, a three-factor and five-level central composite rotatable design (CCRD) with a regression model was used to study the interactive effects of nitrogen (N), phosphorus (P), and potassium (K) fertilization on lipid peroxidation, electrolyte leakage, reactive oxygen species (ROS) production, and their detoxification by the photosynthetic pigments, enzymatic and non-enzymatic antioxidants. The study demonstrated substantial effects of N, P, and K fertilization on ROS production and their detoxification through enzymatic and non-enzymatic pathways in overseeded perennial ryegrass under cold stress. Our results demonstrated that the cold stress significantly enhanced malondialdehyde, electrolyte leakage, and hydrogen peroxide contents, while simultaneously decreasing ROS-scavenging enzymes, antioxidants, and photosynthetic pigments in overseeded perennial ryegrass. However, N, P, and K application mitigated cold stress-provoked adversities by enhancing soluble protein, superoxide dismutase, peroxide dismutase, catalase, and proline contents as compared to the control conditions. Moreover, N, P, and, K application enhanced chlorophyll a, chlorophyll b, total chlorophyll, and carotenoids in overseeded perennial ryegrass under cold stress as compared to the control treatments. Collectively, this 2−years study indicated that N, P, and K fertilization mitigated cold stress by activating enzymatic and non-enzymatic antioxidants defense systems, thereby concluding that efficient nutrient management is the key to enhanced cold stress tolerance of overseeded perennial ryegrass in a transitional climate. These findings revealed that turfgrass management will not only rely on breeding new varieties but also on the development of nutrient management strategies for coping cold stress.

“…Heat stress along with water stress can be also alleviated by the use of products containing reflecting agents as well as osmolytes (such as proline, glycine betaine, trehalose, mannitol, sorbitol, potassium products, etc.) [85,[103][104][105][106][107][108], strigolactones [100,109], salicylic acid [84,100,110,111], seaweed extracts [112], polyamines [84,113], abscisic acid (ABA) and other plant growth regulators [84,107,114], jasmonates [84,99], silicon [102], arbuscular mycorrhizal fungi (AMFs) along with endophytes, plant growth-promoting rhizobacteria (PGPR) and fungi (PGPF) (against drought stress) [94,112,115,116], superabsorbent polymers (SAP) or hydrophilic polymer gels in the soil [84,85], biochar as well as humate compounds incorporation in the soil (against water shortage) [107,117], and melatonin foliar application [96][97][98]118]. On the photo on the left-hand side, there is an earlier flower bud sprouting, and on the right-hand side, there is an earlier leaf emergence compared to the untreated control on the same apricot tree (from personal archive).…”

“…The lack of flowering synchronization can also be overcome by the previous budbreaking agents, while in some species, artificial pollination may be the solution too. A high solar irradiance in summer (heat stress) can be alleviated by overhead net installation (net shading) [84,94,95] (Figure 8), melatonin [96][97][98], jasmonates [99], brassinosteroids [100,101], silicon [102], as well as sugars and sugar alcohols [103,104], and reflecting agent spraying (such as talc, kaolin clay particles, attapoulgite, calcium carbonate) [84,105,106] (Figure 9). Heat stress along with water stress can be also alleviated by the use of products containing reflecting agents as well as osmolytes (such as proline, glycine betaine, trehalose, mannitol, sorbitol, potassium products, etc.)…”

In the last few years, the world has experienced the impacts of climate change, such as elevated mean annual temperature, extreme weather events, drought, etc. Among living organisms, perennial plant species are the ones mostly exposed to climate change impacts, as they may experience different extreme events within the same year, such as flooding during some periods and drought in summer months, extremely low temperatures in winter but excessively high temperatures in summer, etc. Climate change affects a range of physiological functions of temperate fruit and nut tree species, such as their phenophases, bud dormancy release and vernalization, pollination and fruit set, fruit growth and quality, as well as bud sprouting and growth initiation. Besides these, the impact of climate change on pests, diseases, and weeds may generate significant negative interactions with tree physiology, threatening food production, food safety, and human welfare. In the present manuscript, a general aspect of climate change impacts on fruits’ and nut trees’ physiological functions is described and commented on.

“…Any type of environmental factor that hampers plant growth and development can be considered an abiotic stress. Salinity stress is one of the prime abiotic stresses that causes huge productivity loss every year [ 1 ]. It affects around 954 million ha of land, which is approximately 25–30% worldwide land and about half of the total arable land irrigated globally [ 2 ].…”

The severity of salt stress is alarming for crop growth and production and it threatens food security. Strategies employed for the reduction in stress are not always eco-friendly or sustainable. Plant-growth-promoting rhizobacteria (PGPR) could provide an alternative sustainable stress reduction strategy owning to its role in various metabolic processes. In this study, we have used two strains of PGPR, Pseudomonas fluorescens (NAIMCC-B-00340) and Azotobacter chroococcum Beijerinck 1901 (MCC 2351), either singly or in combination, and studied their effect in the amelioration of salt toxicity in mustard cultivar Pusa Jagannath via its influence on plants’ antioxidants’ metabolism, photosynthesis and growth. Individually, the impact of Pseudomonas fluorescens was better in reducing stress ethylene, oxidative stress, photosynthesis and growth but maximal alleviation was observed with their combined application. MDA and H2O2 content as indicator of oxidative stress decreased by 27.86% and 45.18% and osmolytes content (proline and glycine-betaine) increased by 38.8% and 26.3%, respectively, while antioxidative enzymes (SOD, CAT, APX and GR) increased by 58.40, 25.65, 81.081 and 55.914%, respectively, over salt-treated plants through the application of Pseudomonas fluorescens. The combined application maximally resulted in more cell viability and less damage to the leaf with lesser superoxide generation due to higher antioxidative enzymes and reduced glutathione formation (GSH). Considering the obtained results, we can supplement the PGPR in combination to plants subjected to salt stress, prevent photosynthetic and growth reduction, and increase the yield of plants.
