Edible chrysanthemum (Chrysanthemum morifolium Ramat.), widely consumed in Asia, is rich bioactive compounds such as polyphenols, flavonoids, and amino acids. Optimizing cultivation temperature critical for maximizing both yield quality, especially under the challenges posed by climate change. This study evaluated growth performance, photosynthetic characteristics, metabolite accumulation of ‘Taiwan Hangju No. 1’ variety five day/night regimes (15/13 °C, 20/15 25/20 30/25 35/30 °C) over a 220-day period an artificial greenhouse. The °C regime promoted best overall growth, with highest yields bud-leaves flowers, supported net rate, indicating optimal carbon assimilation moderate temperatures. In contrast, stomatal conductance, respiration transpiration rate increased temperature, peaking at °C. Water use efficiency was greatest 15/13 Bioactive compound exhibited complex organ-specific responses to temperature. concentration luteolin, caffeoylquinic acid derivatives (CQAs) free acids decreased rising reaching peak flavonoid peaked accumulated most flavonoids differing flowers various conditions contributed variation total content functional compounds. Except acids, other all demonstrated that provides balance between efficiency, key therefore recommended 1’. These findings reveal temperature-dependent metabolic adjustments, suggesting warming may enhance crop quality if managed carefully. results provide scientific basis climate-adaptive strategies edible chrysanthemums subtropical regions.

In this study, the physiological performance and fruit quality responses of highbush blueberry (Vaccinium corymbosum) cultivar Legacy to high temperatures (HTs) were evaluated in a field experiment. Three-year-old V. corymbosum plants exposed two temperature treatments between load set harvest during 2022/2023 season: (i) ambient (AT) (ii) (HT) (5 °C ± 1 above temperature). A chamber covered with transparent polyethylene (100 µm thick) was used apply HT treatment. our diurnal maintained difference 5.03 0.12 AT treatments. Our findings indicated that significantly decreased CO2 assimilation (Pn) by 45% stomatal conductance (gs) 35.2% compared By contrast, intercellular concentration (Ci) showed higher levels (about 6%) than plants. Fruit analyses revealed weight equatorial diameter 39% 13%, respectively, treatment firmness total soluble solids (TSS) Meanwhile, titratable acidity no changes Pn reduction could be associated non-stomatal limitations under Although these improve understanding impact HTs on growth corymbosum, further biochemical molecular studies are need.
