Grafting pepper onto tolerant rootstocks: An environmental-friendly technique overcome water and salt stress

Pepper Crop under Climate Change: Grafting as an Environmental Friendly Strategy

“…Tolerance to salinity in these grafted plants was expressed to maintain scions' ion homeostasis, and can consequently improve crop yields [148,149].…”

“…The high Na + and Cl − , accumulations and their likely compartmentalization in the apoplastic space and/or vacuole to preserve the cytosol from ionic toxic effects could well occur. Tolerance may be attributed to the ability to maintain shoot/root growth under salt stress, which has been related to A/A25 plants' ability to limit, or protect, loss of CO 2 assimilation (Figure 6) and sink activity in growing organs [149,150]. ) of the cultivar Adige ungrafted (A) or grafted onto the A25 genotype (A/ A25) under control (white bars) and salinity conditions (black bars).…”

“…Considering the overall results published about grafts, grafted plants can act as an efficient tool to mitigate abiotic stress in the climate change context and a tolerant rootstock that can make water and salt stress vanish on scions to reach greater productivity and fruit quality [149]. Nonetheless, the physiological and genetic mechanisms for abiotic tolerance in grafted plants, especially in peppers, are still unknown.…”

Response of Bell Pepper to Rootstock and Greenhouse Cultivation in Coconut Fiber or Soil

“…The original purpose of plant grafting was to avoid diseases caused by soil parasites and pathogens, such as Verticillium, Fusarium, Phytophthora, Ralstonia, and Nematodos [9,10]. In actuality, grafting can also be used to mitigate abiotic stress [11,12], increase yields, improve fruit quality, and extend harvest times, as well as reduce agrochemical applications [13,14] and improve the commercial quality of crops [15,16], as it is effective at preventing soil-borne diseases and pests [17]. In eggplant, the rootstock used induced notable vigor and better yield [18,19], the latter of which favors the global reduction of dependency on synthetic agrochemicals [1].…”

“…The use of this technique with commercial varieties of bell pepper could significantly reduce the losses caused by P. capsici by up to 100% [23,24]. The use of grafting also increases yields by up to 50% [25,26], resulting in increased commercial yields [11]. Yield increases of up to 35% [17,27] and a 35% increase in the quality of exported tomatoes [16] have both been reported for grafted tomato.…”
