“…Several studies have demonstrated that elevated concentrations of CO 2 increase the yield of strawberry compared with ambient conditions [55][56][57][58][59][60]. This response suggests that higher concentrations of CO 2 under climate change will counteract the impacts of higher temperatures.…”

Light, temperature and rainfall affect the growth and yield of strawberry plants (Fragaria × ananassa Duch.). The objective of this review was to determine the impact of global warming on the yields of strawberry in a temperate (summer crop) and subtropical environment (winter crop) in southern Queensland, Australia. Information was collected on the changes in temperature over five decades in two locations in this area. The relationship between relative yield and temperature from published data was used to determine the impact of global warming on productivity in the two locations. Finally, the impact of elevated concentrations of CO2 and temperature on yield was examined from studies in the literature. The average daily mean temperature has increased by 2 °C over the season on the Sunshine Coast (winter crop) since 1967 (p < 0.001, R2 = 0.69). The impact of global warming has been less severe on the Granite Belt (summer crop), with a 1 °C increase in temperature (p < 0.001, R2 = 0.37). Information was collected from the literature on the yield in individual temperature regimes in an experiment and these data were compared with the maximum yield in the same experiment (relative yield). There was a negative linear relationship between relative yield and temperature in most of the published literature. The mean (± s.d. or standard deviation) estimate of the slope from the regression was −0.14 (± 0.14), the median was −0.11 and the range was from −0.51 to 0.11 (n = 14 studies). Increases in temperature were associated with a decrease in yield of 14% to 28% in the two areas in Queensland. The results of other research indicated that elevated concentrations of CO2 do not benefit productivity when combined with elevated temperatures. Further decreases in yield are expected in the next few decades in the absence of heat-tolerant cultivars or other mitigating strategies.

“…However, precise control was developed using an application controller with a liquefied CO 2 gas cylinder, which made it possible to apply CO 2 locally within the plant canopy. When this application method was applied to the cultivation of ever-bearing strawberries, we succeeded in maintaining plant vigor during the cultivation period and increasing the yield by 30% (Mochizuki et al, 2022). However, CO 2 application promoted the expansion of leaf area, but self-shading of the leaves did not improve light use efficiency.…”

“…Furthermore, it has been reported that the leaves are affected by wind and swaying, which was effective in increasing the total dry weight of cucumbers (Umeda et al, 2016). The porous tube which was used our previous study (Mochizuki et al, 2022) can supply not only CO 2 , but also air using the same tube. By increasing the amount of CO 2 applied, a further increase in income can be expected, but the investment and increase in income cannot be balanced economically.…”

Strawberries can be categorized into June-bearing and ever-bearing depending on the environmental conditions that determine flower bud initiation. In Japan, the harvest yield and distribution of strawberry fruits during summer and autumn are low because of high temperatures and heavy fruit load. Therefore, cultivation of ever-bearing strawberries is limited to areas with cool summers such as Hokkaido and Tohoku. In this study, we investigated whether air treatment before liquefied carbon dioxide (CO 2 ) application within the strawberry plant canopy could improve CO 2 absorption efficiency and increase dry matter production. Four treatments were investigated: application of air within the plant canopy, application of CO 2 , application of CO 2 after air application, and a control. We investigated the CO 2 concentration, dry matter production, yield characteristics, individual leaf photosynthesis characteristics, projected leaf area, cumulative light interception, light use efficiency, and fruit quality. The results showed that the local application of only CO 2 or Air and, application of CO 2 after air application (Air/CO 2 ) treatment within the plant canopy considerably increased the dry matter production. Total fruit yield of Air/CO 2 was the highest among all treatments. This is probably because the application of CO 2 and air expanded the leaf area, increased cumulative light interception, and improved light use efficiency. In addition, the photosynthetic rate of Air, CO 2 and Air/CO 2 treatments was higher than that of the control because of higher stomatal conductance. This suggests that local application of liquefied CO 2 after air application can effectively increase fruit yield, and that air treatment will improve plant vigor, further increasing strawberry production in summer and autumn.
