Grafting improves nitrogen-use efficiency by regulating the nitrogen uptake and metabolism under low-nitrate conditions in cucumber

Effect of Self- and Inter-Cultivar Grafting on Growth and Nutrient Content in Sweet Basil (Ocimum basilicum L.)

“…Thus, differences in root system traits may not have played a critical role in plant growth. Our finding also differs from grafting studies in tomato ( Djidonou et al, 2019 ) and cucurbits ( Nawaz et al, 2017 ; Liang et al, 2021 ) that have found increased plant vigor and yield due to the enhanced nutrient uptake and supply by the rootstock. While basil growth seems relatively unaffected by nutrient supply, studies have shown nutrient supply to alter the concentrations of commercially important compounds in basil ( Zheljazkov et al, 2008 ; Ciriello et al, 2020 ; Kolega et al, 2020 ).…”

“…Root system size and architecture are often cited as one of the reasons for high performance of grafted plants. Vigorous vegetable rootstocks have been shown to have longer root length, smaller root diameter and higher specific root length ( Suchoff et al, 2018 ) and increased root volume, surface area and branching ( Huang et al, 2016 ; Liang et al, 2021 ). Conversely, dwarfing apple rootstocks have been shown to produce fewer fine roots than more vigorous rootstocks, indicating a role of root size in dwarfed growth ( An et al, 2017 ).…”

“…In addition to disease management, other beneficial applications of grafting have been identified. For example, certain scion-rootstock combinations have proven more tolerant to environmental stress conditions including high ( López-Marín et al, 2013 ) or low (e.g., Fu et al, 2021 ) temperature, nutrient deficiency (e.g., Liang et al, 2021 ), metal toxicity (e.g., Kumar et al, 2015 ), salinity (e.g., Estañ et al, 2005 ), drought (e.g., Penella et al, 2014 ), and flooding (e.g., Bhatt et al, 2015 ). Grafting has also been shown to improve the fruit quality ( Kyriacou et al, 2017 ) as well as enhance overall plant vigor and yield in solanaceous (e.g., Leonardi and Giuffrida, 2006 ; Masterson et al, 2016 ) and cucurbit (e.g., Oztekin et al, 2011 ; Huang et al, 2016 ) crops.…”

“…Even in commonly grafted and well-studied crops such as cucurbits and tomatoes, grafting-induced vigor has not been fully understood. Among limited information, enhanced water and nutrient uptake and use efficiency by grafting have been reported in cucurbits ( Nawaz et al, 2017 ; Liang et al, 2021 ) and solanaceous crops ( Leonardi and Giuffrida, 2006 ; Albornoz et al, 2018 ). This enhanced uptake is often attributed to improved root system size and architecture ( Huang et al, 2016 ; Suchoff et al, 2018 ; Liang et al, 2021 ) or more efficient nutrient transporters ( Albornoz et al, 2018 ).…”

Untargeted metabolism approach reveals difference of varieties of bud and relation among characteristics of grafting seedlings in Camellia oleifera

“…The metabolomic analysis was widely used to study critical agricultural traits, such as flavor, yield, biomass, and nutritional quality. It was confirmed that grafting significantly increases the content of primary metabolites in Cucumber (Liang et al, 2021) and watermelon fruits (Aslam et al, 2020;. In addition to biosynthesis and accumulation in a tissue-specific manner, metabolites could be produced and transported across tissues and organs to regulate biological processes (Van de Poel et al, 2014).…”
