Special Issue Information

Dear Colleagues,

Climate change is among the most challenging risks that the planet is facing. Many issues of human activities are being affected by this environmental threat. Directly in the shape of global temperature rising, random or very damaging rain patterns, floodings, or indirectly like changes in the incident solar radiation, soil erosion, among others. In this regard, horticulture is affected by water scarcity for irrigation, a decrease in the quality of water and/or agricultural soils (salinization or toxic ions), crop development and growth, fruit setting and yield, fruit quality and physiopaties, and even the quality of processed foods as a consequence (e.g. wines, olive, and other oils). In this frame, the approaches to solve or mitigate these and other effects of climate change on crops can be very diverse.

Thus, this Special Issue, “Strategies of Producing Horticultural Crops under Climate Change”, is aimed at innovative studies working with a range of alternatives to fight against climate change and its effects on horticultural production. Works on soil and environmental solutions, biofertilizers or mycorrhization, seed management and solutions, irrigation techniques, crop rotation, mulching, plant-and-soil interactions, plant breeding, valorization of new crops, plant protection, recovery and application of useful ancestral techniques, just as examples, aimed at improving the growth, yield, and/or quality of horticultural crops, will be welcomed in this SI.

The excessive use of irrigation water and fertilizers in agriculture raises serious environmental concerns, emphasizing the need for more sustainable practices. Screening genotypes with reduced nutrient and water requirements, combined with favorable responses to plant growth-promoting rhizobacteria (PGPR), offers a promising strategy for developing more sustainable farming systems. Seven sweet pepper genotypes (Capsicum annuum L.) were evaluated under six treatments, involving two fertilization levels (100% and 50% standard dose), two irrigation regimes (100% and 75% full irrigation), and PGPR inoculation applied under reduced fertilization. Yield, fruit weight, rhizosphere enzymatic activities, and soluble sugars in green and red fruits were evaluated. The genotype effect contributed significantly to all traits. Combined reductions in fertilizer and irrigation decreased average yield by 21.7%, while PGPR did not fully compensate for these losses. Alkaline phosphomonoesterase activity increased by 22.9% under low fertilization, whereas averaged catalase and dehydrogenase remained relatively stable regardless of PGPR. In green fruits, PGPR inoculation under combined stress conditions increased glucose and fructose concentrations by 11.6% and 13.9%, respectively, compared to uninoculated stressed plants, although sucrose decreased. At fully ripe stage, sugar composition was less responsive to treatments. These findings underscore the importance of genotype evaluation and the exploitation of genotype × treatment interactions in peppers breeding for sustainable farming. Full article

Olive trees are generally considered a species well-adapted to drought, but the impact of water shortage is of critical importance on olive production. For this reason, developing tolerant cultivars could be an effective strategy to mitigate the impact of drought in the future. Characterizing drought stress tolerance in olive is a complex task due to the numerous traits involved in this response. In this study, plant growth, pressure–volume curves, gas-exchange and chlorophyll fluorescence traits, and stomata characteristics were monitored in nine cultivars to assess the effects of mild and severe drought stress conditions induced by withholding water for 7 and 21 days, respectively, and were compared to a well-watered control treatment. The plant materials evaluated included traditional cultivars, as well as new developed cultivars suited for high-density hedgerow olive orchards or resistant to verticillium wilt. Significant differences between cultivars were observed for most evaluated traits, with more pronounced differences under severe drought conditions. A multivariate analysis of the complete dataset recorded throughout the evaluation period allowed for the identification of promising cultivars under stress conditions (‘Sikitita’, ‘Sikitita-2’, and ‘Martina’) as well as highly discriminative traits that could serve as key selection parameters in future breeding programs.
