What is Grafting to Enhance Abiotic Stress Tolerance?

Grafting to enhance abiotic stress tolerance fuses tolerant rootstocks with commercial scion varieties to improve plant survival under drought, salinity, and temperature extremes.

This technique leverages rootstock traits to boost scion water use efficiency and ion homeostasis (Kumar et al., 2017; 215 citations). Studies quantify physiological responses like photosynthesis and yield stability in grafted peppers and tomatoes (López-Serrano et al., 2019; 370 citations). Over 20 papers from 2011-2021 document grafting's role in vegetable crops.

Key Challenges

Why It Matters

Grafting onto drought-tolerant rootstocks like A25 pepper increases yield under water deficits, supporting food security in arid regions (López-Serrano et al., 2019). It enhances salinity tolerance in melons and cucumbers by protecting photosynthetic apparatus (Rouphael et al., 2012). Rouphael et al. (2018) show yield stability under combined stresses, vital for climate-impacted agriculture (134 citations). Kyriacou et al. (2017) link it to nutritive value in intensive production (235 citations).

Key Research Challenges

Rootstock-scion compatibility

Taxonomic proximity is required for graft union formation and long-term survival (Rasool et al., 2020; 189 citations). Incompatible grafts fail due to poor vascular connections. Mechanisms like hormone signaling need clarification (Rasool et al., 2020).

Quantifying stress tolerance

Measuring physiological responses like PEG-induced water stress in peppers requires standardized assays (Penella et al., 2014; 76 citations). Variability in field vs. lab conditions complicates metrics. Yield and WUE data show inconsistencies across crops (Djidonou et al., 2013; 86 citations).

Ion accumulation control

Rootstocks modify Na+ and Cl- uptake under salinity, but optimal selection varies by crop (Nawaz et al., 2016; 200 citations). Balancing nutrient efficiency with stress exclusion remains unresolved. Eggplant grafting trials highlight composition trade-offs (Gisbert et al., 2011; 155 citations).
