Editorial: Combined abiotic interactions in woody plants

Résumé fourni par la source

Combined abiotic stress interactions, such as the simultaneous occurrence of drought \nand high temperatures, significantly impact plants’ physiology, growth, and survival. The \noccurrence of multiple stressors often exacerbates the effects of each other, leading to \ncompounded challenges for plants (Zandalinas and Mittler, 2022). Additionally, the energy \nexpenditure required to combat multiple stresses can deplete the plant’s reserves, hindering \nits growth and reproductive capabilities (Maurya et al.). Over time, such compounded \nstresses can lead to reduced ecosystem productivity, altered species composition, and \npotentially increased plant mortality rates. Understanding stress interaction effects is \nessential due to the complexity of climate change, which is increasing both the \nfrequency and severity of droughts and heatwaves across the globe (Tripathy et al., \n2023). The impact of these two stressors can have devastating effects on sites already \naffected by other abiotic stressors such as higher soil salinity, heavy metals or other ecotoxic \nchemicals. Moreover, the land use legacy can also amplify negative impact on trees, \nespecially in urban ecosystems (Cui et al.). The articles in this Research Topics explored the \neffects of drought and heat stress, light availability and heavy metal stress on the growth and \nphysiology of trees.
