“…They assumed that this effect is due to lowered temperature in the greenhouse and thereby lowered transpiration. Lower leaf transpiration could favour water and thereby calcium supply to the fruits and like this reduce BER (Balate et al 2018) instead of to the higher transpiring leaves.…”

LED lighting has emerged as alternative to the current HPS standard in greenhouse production. However little is known about the impact on fruit quality under the different light spectra. We grew a biparental tomato RIL population between September 2019 and January 2020 under two commercial greenhouse supplemental lighting conditions, i.e. HPS, and 95% red/ 5% blue- LED, of about 220 µmol m− 2 s− 1 at maximum canopy height for 16h per day. Differences in Brix and blossom-end rot (BER) between the two light conditions were observed and we studied the genetic influences on those traits, separating genetics located on chromosomes from genetics located in plastids. The Brix value was on average 11% lower under LED than under HPS supplemental lighting. A LED-light specific QTL for Brix was identified on chromosome 6. This QTL can be of interest for breeding for tomato varieties cultivated under LED supplemental lighting. A Brix-QTL on chromosome 2 was found for both light conditions. In our study fewer plants developed BER under LED supplemental lighting than under HPS. We identified a novel genetic locus on chromosome 11 for the incidence of BER that lead to a difference in about 20% of fruits with BER. This genetic component was independent of the light.

“…Previous literature has reported variation in nutrient accumulation amongst plant genotypes (Cheng and Raba 2009;Schloss et al 2017;Balate et al 2018). Research has shown some apple scions are better able to accumulate mineral nutrients in both leaves and fruit (de Freitas et al 2015;Valverdi et al 2019;Valverdi et al 2021).…”

Plant nutrient uptake is critical to maintain an optimum balance between vegetative and reproductive growth and fruit quality. Nutrient imbalances, and more specifically the relationship of potassium, magnesium and nitrogen to calcium, can be critical for fruit quality in apple (Malus x domestica Borkh.). In perennial plants, it is difficult to conduct short-term experiments to measure plant uptake and distribution in response to either cultivar or treatment because of substantial preexisting nutrient pools already present. The use of isotopically labeled nitrogen, and nutrient analogs such as strontium and rubidium allow for the quantification of uptake and distribution that is often not possible with bulk mineral analysis. Here, the objective was to understand how scion genotype influences nutrient uptake and partitioning between aboveground and below ground parts of the tree. In this experiment, 10 atom% 15 N, Strontium (Sr), and Rubidium (Rb) were applied to three different potted apple cultivars that were either treated with ABA 250 mg/L or 500 mg/L or an untreated control. After 70 days of growth, overall recovery rates of each tracer reflected the mobility of their nutrient analog. Strontium had an average tracer recovery rate of 3.9%, followed by 15 N with 14.6% recovery and finally Rb with 15.1%. Independent of treatment, 'Gala' significantly absorbed more tracer followed by Granny Smith and Honeycrisp for Rb and Sr but not 15 N. These results have implications in understanding the association between aboveground factors like transpiration and nutrient uptake and distribution in apple.

“…Changes in the plant's available water, in this case, might affect fruit development issues such as blossom end rot, a physiological disorder that causes sunken necrotic lesions in tomatoes resulting from calcium (Ca) deficiency (Saure, 2001). Water restriction is one of the main causes of limited Ca uptake by roots and can thus lead to Ca deficiency and blossom end rot (Balate et al, 2018). Yields are likely to increase as water stress is lowered.…”

Farmers faced with increasingly limited access to freshwater for irrigation are utilizing dry farming techniques to produce fruit, vegetable, and grain crops. Defined as crop production during a dry season using little or no irrigation, dry farming relies on water stored in the soil and requires specialized soil management, healthy soil biology, and careful selection of crop varieties. We investigated these three factors in a dry-farmed tomato (Solanum lycopersicum) field trial with three indeterminate varieties (Early Girl, Momotaro, and Zapotec) and two determinate genotypes (76R and rmc), the latter serving as a model system for studying the role of arbuscular mycorrhizal (AM) fungi. While five prior years of contrasting surface tillage practices changed soil properties, they did not affect marketable tomato yields or quality, nor affect plant physiology, including plant water use efficiency [intrinsic (WUEi) and long-term (δ13C)], gas exchange, stem water potential (Ψstem), and leaf relative water content (RWC). Early Girl produced a greater number of fruits and fewer non-marketable fruits than Momotaro and Zapotec. Although AM fungi root colonization was very low for both wildtype mycorrhizal genotype 76R and its reduced mycorrhizal mutant rmc, it differed significantly depending on genotype and tillage treatment. 76R produced slightly greater marketable fruit, but physiological responses did not differ significantly between genotypes. This study does not provide field-based evidence that soil chemical and biological changes resulting from no-till influence dry-farmed tomato productivity, while genotype had a clear impact on tomato yield and quality. Field-scale tillage experiments may better capture soil physical changes that affect water availability, especially at depth, and should be examined.
