Methyl Jasmonate Applications From Flowering to Ripe Fruit Stages of Strawberry (Fragaria × ananassa ‘Camarosa’) Reinforce the Fruit Antioxidant Response at Post-harvest
Camarosa strawberries showed changes in some antioxidant responses. Total phenolics at harvest did not differ significantly in the extracted comparison.
Limit: The numerical decrease is not demonstrated harm. Total phenolics and ORAC did not differ significantly; other antioxidant endpoints responded. No overall yield increase established.

Gene network underlying the response of harvested pepper to chilling stress
MeJA changed the transcriptome of harvested peppers during chilling storage, including antioxidant-enzyme and ethylene-response genes. The authors link these changes to cold-stress responses.
Limit: Primarily mechanistic evidence; gene-expression responses are not a measured yield benefit or validated shelf-life prediction. Numeric extraction pending.
Review depth: Publisher or indexed primary-study abstract checked; full text not audited
The pretreatment of cucumber with methyl jasmonate regulates antioxidant enzyme activities and protects chloroplast and mitochondrial ultrastructure in chilling-stressed leaves
MeJA pretreatment alleviated growth inhibition during experimental chilling and protected chloroplast and mitochondrial structure in cucumber leaves.

Effects of Jasmonates on in vitro Tuberization in Several Potato Cultivars that Differ Greatly in Maturity
Jasmonic acid and airborne methyl jasmonate induced tuberization in cultured potato material. Responses varied with cultivar maturity, with an exception among the late-maturing cultivars.
Limit: Tissue-culture tuberization cannot be treated as field yield. JA and MeJA exposure methods need separate extraction. Numeric extraction pending.

A Jasmonate-Induced Defense Elicitation in Mature Leaves Reduces Carbon Export and Alters Sink Priority in Grape (Vitis vinifera Chardonnay)
Repeated methyl jasmonate treatment reduced root biomass in nonfruiting Chardonnay vines. This shows a potential growth tradeoff from defense induction.
Limit: Not a field-yield trial. Separate 1 mM JA experiments show reduced photosynthesis/carbon export; do not attribute those methods or outcomes to the MeJA biomass arm. No graph-digitized number in calculator.
Review depth: Open full text checked; selected comparisons extracted
Effects of Methyl Jasmonate Treatment after Harvest on Blue Mould and Storage Quality of ‘Fuji’ Apple Fruit
MeJA dipping reduced blue mould in wounded Fuji apples inoculated with Penicillium expansum and altered antioxidant-related responses. Flesh hardness, soluble solids, and titratable acidity were not significantly affected.
Limit: Artificially wounded and inoculated fruit; results are not a field disease-control or crop-yield estimate. Numeric extraction pending.

Preservation treatment with methyl jasmonate alleviates chilling injury disorder in pear fruit by regulating antioxidant system and energy status
MeJA fumigation reduced chilling injury in Yali pears during cold storage and was associated with antioxidant activity and better-maintained energy status.
Limit: Yali cultivar under the tested storage conditions; not evidence for all pear species or field yield. Issue year is 2022, with online publication in 2021. Numeric extraction pending.

Changes in physiology and quality of peach fruits treated by methyl jasmonate under low temperature stress
MeJA-treated Jiubao peaches developed less chilling injury during cold storage and subsequent shelf life, with changes in quality and cell-wall-related physiology.
Limit: A postharvest cultivar-specific experiment; chilling protection cannot be converted into a general fruit-yield gain. Numeric extraction pending.

Preharvest application of methyl jasmonate (MeJA) in two plum cultivars. 1. Improvement of fruit growth and quality attributes at harvest
Preharvest MeJA increased fruit size and weight in Black Splendor and Royal Rosa plums; the most effective concentration differed by cultivar. Firmness and selected bioactive compounds also changed.
Limit: Fruit size is not total marketable yield per tree. Two cultivars and one reported growing cycle do not support general dose recommendations. Numeric extraction pending.

Sweet Cherry (Prunus avium L.) Cracking during Development on the Tree and at Harvest: The Impact of Methyl Jasmonate on Four Different Growing Seasons
Preharvest MeJA reduced cracking across the tested sweet-cherry cultivars and seasons. It also generally delayed ripening and polyphenol accumulation.
Limit: Cultivar, rainfall, and maturity context matter; delayed ripening is a tradeoff. This is not a universal cracking or yield forecast. Numeric extraction pending.

Preharvest application of methyl jasmonate increases fruit quality and antioxidant capacity in raspberries
Field-grown red and black raspberries treated with MeJA had higher measured sugars, flavonoids, and antioxidant capacity, with lower acidity than untreated fruit.
