“…Throughout the history of agriculture, several methods have been adopted to achieve better crop tolerance to stresses and production in unfavorable environmental conditions. These entail breeding strategies (selection and hybridization, molecular breeding, genetic engineering) (Athar & Ashraf, 2009;Waqar et al, 2014), agronomic strategies (variety selection, date of sowing, soil management, irrigation) (Mariani & Ferrante, 2017;Lamaoui et al, 2018), physiological approaches (seed priming, foliar spray) (Bakhtavar et al, 2015), etc. The success of breeding techniques is often limited due to huge requirement of skilled manpower and energy, complexity associated with stress tolerance traits, tedious and costly methods, and ethical regulations.…”

<p>Priming techniques are gaining importance in agriculture with the increase in environmental stresses. Resource-poor farmers are in urgent need of such techniques as they are simple, economical, and value-added intervention associated with low-risk bearing factors. Seed enhancement methods are key to improve seed performance and achieve a good stand establishment. Worldwide beneficial effects of priming are recorded. But these technologies have still not reached most farmers. This review highlights the importance of on-farm priming strategies in modern crop production system to yield better productivity and obtain higher economic returns. Stimulation of the pre-germination metabolic changes by priming is necessary to overcome the environmental challenges that a plant can encounter. Thus, the study also focuses on mechanisms associated with priming-induced stress tolerance of crops. Various safe practical methods of seed priming can be easily adopted by the farming community to alleviate the levels of different stresses which can hamper productivity. Simultaneously they can produce good quality seeds and use them further for the next crop cycle cutting the costs of seed purchase.</p>

“…Together with the progress of climate change, grows the importance of intergeneric hybrids in breeding projects aimed at obtaining new cultivars or crop species with increased tolerance to environmental stresses, including soil drought (Ali et al, 2020 ; Rauf et al, 2016 ; Waqar et al, 2014 ).…”

The aim was to identify subgenome‐related specific responses in two types of triticale, that is, of the wheat‐dominated genome (WDG) and rye‐dominated genome (RDG), to water stress induced in the early phase (tillering) of plant growth. Higher activity of the primary metabolism of carbohydrates is a feature of the WDG type, while the dominance of the rye genome is associated with a higher activity of the secondary metabolism of phenolic compounds in the RDG type. The study analyzed carbohydrates and key enzymes of their synthesis, free phenolic compounds and carbohydrate‐related components of the cell wall, monolignols, and shikimic acid (ShA), which is a key link between the primary and secondary metabolism of phenolic compounds. Under water stress, dominance of the wheat genome in the WDG type was manifested by an increased accumulation of the large subunit of Rubisco and sucrose phosphate synthase and a higher content of raffinose and stachyose compared with the RDG type. In dehydrated RDG plants, higher activity of L‐phenylalanine ammonia lyase (PAL) and L‐tyrosine ammonia lyase (TAL), as well as a higher level of ShA, free and cell wall‐bound p‐hydroxybenzoic acid, free homovanillic acid, free sinapic acid, and cell wall‐bound syringic acid can be considered biochemical indicators of the dominance of the rye genome.
