In chili pepper,yield increases of 43.80/0—142%were reported for e[CO2](in the range of 50o ppm—1140 ppm).These yield increases were in part attributed to an increase in the size of fruits[49].However,in controlled environments a 4°C increase in temperature decreased yield,even at e[CO2](75o ppm)[5o,51],indicating that carbon enrichment is not sufficient to rescue yield where glasshouse facilities or growth tunnels experience periods of elevated temperature in an extreme climate change scenario.Carbon-enriched growth was found to increase the capsaicinoid content of fruits,resulting in an increase in Scoville Heat Units(SHU)[49,52].This approach therefore has potential for producing hotter varieties of chili,a growing and competitive market.However,at the same time Vitamin C concentration decrease by up to 15.84%[53],reducing potential health benefits gained from growing chilli plants under e[CO2].(Table 2). These reports suggest that the effects of growing crops in e[CO2]can have both a positive influence on yield and nutritional quality,however, growth at[CO2]levels above what is optimum can negatively impact some quality traits. Impact of elevated [CO2] on rosaceous crops Rosaceous crop research in this area has focused primarily on cultivated strawberry with a small number of studies on raspberry and Nashi pear (Table 3).This is likely due to the relatively smaller size and rapid growth of strawberry compared to other commercially important rosaceous fruit species,such as tree fruits,like apple and cherry,and woody stemmed shrub fruits,like raspberry and blackberry.This makes strawberry a convenient plant to study as a rosaceous model.Furthermore,greater production of strawberry fruits would not only increase profits for growers PDF but also decrease costs for consumers,increasing the availability of healthier options.Better access to such products through economic growth is strongly correlated to reduced micronutrient malnutrition or"hidden hunger"[54].
