WebMay 19, 2024 · Main conclusion Drought stress during grain filling is the most yield-damaging to wheat. Pre-drought priming facilitated the wheat plants to sustain grain development against the post-anthesis drought stress by modulating the levels of growth hormones. Post-anthesis drought stress substantially reduces grain yield in wheat … WebJun 3, 2024 · Crucially, quantifying drought stress before it can be detected visually—by identifying plants in the pre-drought condition using spectroscopy to detect known leaf-level metabolic changes caused by drought stress—would provide a major advance in drought prediction and mitigation.

WebMay 26, 2016 · 2.2.2 Plant Acclimation to Drought. Plant priming, which differs from seed priming, is a process that an earlier exposure to biotic stress enhances plants’ tolerance to later abiotic or biotic insult (Chen and Arora 2012; Bruce et al. 2007).The similar process, with abiotic stress as the first exposure instead of biotic stress, is considered as … WebJan 31, 2024 · Pre-anthesis drought is expected to greatly increase yield losses in wheat (Triticum aestivum L.), one of the most important crops worldwide. Most studies investigate the effects of pre-anthesis drought only at maturity. The physiology of the plant before anthesis and how it is affected during drought is less studied. Our study focused on … WebMar 14, 2024 · Early heat and drought priming may increase the plant’s ability to resist later drought and heat stress. However, it remains unclear whether combined heat and drought priming can enhance the acclimation of plants to later combined stress by improving physiological activities.
