“…The first clear conclusion from these results was that 1,500 ppm CO 2 is the best among the three conditions tested for the best yield of carbon in fruits in Micro-Tom cultivation with our system. In a previous report with a greenhouse, the fruit yield of tomato was enhanced by 7-34% by feeding CO 2 to 1,000 ppm (Tripp et al 1991). Our results for the enhancement of translocation of fixed carbon ( Figure 4B) seemed to be in agreement with these results, although it should be stressed that there are many differences between long-term acclimation and shortterm response to elevated CO 2 (Makino and Mae 1999).…”

“…Tripp et al (1991) demonstrated that fruit yield of eight genotypes of tomato was enhanced by 7-34% by feeding CO 2 to 1,000 ppm in a greenhouse, and reported that the enhancement was directly correlated with decrease in root fresh weight, but not with increase in foliar photosynthetic activity. Duan et al (2014) employed 14 CO 2 and 18-day-old Arabidopsis thaliana seedlings to demonstrate that cultivation under increased CO 2 (780 ppm), in comparison with ambient CO 2 (390 ppm), conferred a higher capacity for translocation of photoassimilates from source leaves to sink organs probably by up-regulation of genes related to photosynthesis and sucrose transport, and of plasmodesmal biogenesis.…”

To maximize fruit yield of tomatoes cultivated in a controlled, closed system such as a greenhouse or a plant factory at a limited cost, it is important to raise the translocation rate of fixed carbon to fruits by tuning the cultivation conditions. Elevation of atmospheric CO 2 concentration is a good candidate; however, it is technically difficult to evaluate the effect on fruit growth by comparing different individuals in different CO 2 conditions because of large inter-individual variations. In this study, we employed a positron-emitting tracer imaging system (PETIS), which is a live-imaging technology for plant studies, and a short-lived radioisotope 11 C to quantitatively analyze immediate responses of carbon fixation and translocation in tomatoes in elevated CO 2 conditions. We also developed a closed cultivation system to feed a test plant with CO 2 at concentrations of 400, 1,500 and 3,000 ppm and a pulse of 11 CO 2 . As a result, we obtained serial images of 11 C fixation by leaves and subsequent translocation into fruits. Carbon fixation was enhanced steadily by increasing the CO 2 concentration, but the amount translocated into fruits saturated at 1,500 ppm on average. The translocation rate had larger inter-individual variation and showed less consistent responses to external CO 2 conditions compared with carbon fixation. Our experimental system was demonstrated to be a valuable tool for the optimization of closed cultivation systems because it can trace the responses of carbon translocation in each individual, which are otherwise usually masked by interindividual variation.

“…Nederhoff (1994) also reported that CO 2 elevation increased FDF in cucumber and sweet pepper plants, and maintained it in tomato plants. An increase in FDF by CO 2 elevation was reported by Tripp et al (1991) in 7 tomato cultivars. Similarly to these previous reports, no reduction of FDF by ECF was observed in Ab and Af (Fig.…”

“…Elevation of carbon dioxide (CO 2 ) concentration in a greenhouse was also described as effective to improve the yield of greenhouse crops (de Gelder et al, 2005;Fierro et al, 1994;Hicklenton and Jolliffe, 1978;Nederhoff, 1994;Tremblay and Gosselin, 1998;Tripp et al, 1991). CO 2 application had been unpopular in Japan since most greenhouse crops such as tomatoes were produced in simple plastic greenhouses without an environmental control system.…”

Decreasing or Non-decreasing Allocation of Dry Matter to Fruit in Japanese Tomato Cultivars in Spite of the Increase in Total Dry Matter of Plants by CO2 Elevation and Fogging

et al. 2015

To investigate the mechanism of yield increase by elevated carbon dioxide (CO 2 ) and fogging in Japanese tomato cultivars (Solanum lycopersicum), total above-ground dry matter (TDM), fraction of dry matter distribution to fruit (FDF), and photosynthetic characteristics were measured in 3 Japanese cultivars grown in elevated CO 2 with fogging and ambient CO 2 without fogging. Fresh fruit yield and TDM were improved by the elevated CO 2 and fogging in the 3 Japanese cultivars. Light use efficiency (LUE) was also increased by the elevated CO 2 and fogging. No significant decrease in FDF was observed by the elevated CO 2 and fogging in 2 Japanese cultivars, 'Asabiyori 10' and 'Junkei Aichi Fast'. Thus, the increase in TDM by higher LUE contributed directly to the yield increase in these 2 cultivars. However, FDF in 'Momotaro York' was decreased significantly by the elevated CO 2 and fogging. Thereby, the yield increase by the elevated CO 2 and fogging was diminished in 'Momotaro York' in spite of the increase in TDM. The number of trusses having immature fruit in 'Momotaro York' under elevated CO 2 and fogging was significantly higher than those of the others, although no increase in the number of trusses having immature fruit was observed in the other 2 cultivars. Although vegetative growth characteristics such as leaf area, LAI, and fresh and dry weights of leaves and stem were increased by the elevated CO 2 and fogging, no negative effects such as a change in lightextinction coefficient and a decrease in maximum photosynthetic rate were observed. The elevated CO 2 and fogging increased the number of harvested fruit but decreased weight per fruit, namely, fruit size, in the 3 cultivars.

“…In later years 350 ppm CO 2 was used as the reference point. Assuming a starting point of 350 ppm CO 2 , early research showed that C 3 photosynthesis crop yields (temperate dicots and cereals such as soybean, peanut, dry bean, rice, and wheat) increased about 30% with a doubling of CO 2 , from 350 to 700 ppm for rice (Baker et al 1990;Baker et al 1992;Baker et al 1995), peanuts (Prasad et al 2003), common beans (Prasad et al 2002) Reddy et al 2000), and tomatoes (Tripp et al 1991). Except for sweet corn (which is a C 4 plant), all of Florida's vegetable crops, fruits, and citrus are C 3 species and are presumed to have CO 2 responses similar to the other C 3 crops (for details see summaries of measured crop response to CO 2 reviewed by Backlund et al (2009) and Kimball et al (2002), and crop model responses to CO 2 reviewed by Boote et al (2010)).…”

In this chapter, we describe Florida's agriculture, the vulnerability of its crops and livestock to climate change and possible adaptation strategies. Much of Florida's agricultural success is linked to its moderate climate, which allows vegetable and fruit crop production during the winter/spring season as Key Messages• Florida's agricultural industries provide over $120 billion in economic revenue to the state, second only to tourism, and support more than two million jobs.• Florida's diverse climate conditions make it suitable for many crops, fruits, livestock, and seafood, although these are vulnerable to climate variations that occur from year to year.• Florida's agriculture has a long history of successful adaptations to the vagaries of weather and climate, but climate change poses a challenge that is unprecedented in magnitude and rates of change.• Although current temperatures are near optimal for growing many of our crops, yields are lower during the hotter seasons that occur now, and additional increases in future temperatures will lead to lower crop yields, creating challenges to the competitiveness of current production systems.• Florida's agriculture faces additional challenges from climate change characterized by sea level rise and intensified extreme climate events, affecting land and irrigation water 236 • YOUNG GU HER ET AL.availability, crop yield and quality, livestock productivity, as well as pest and disease pressures.• The known increases in atmospheric CO 2 concentration can stimulate growth in some crops but will reduce the nutritional value of many food crops. Higher atmospheric CO 2 concentration will also increase canopy temperatures and could add to the adverse effects of temperature.• New technologies and adaptation strategies needed for sustainable agricultural production in Florida include increased water and nutrient use efficiency in crops, crop and livestock breeding for heat stress, pest and disease resistance, and reduced exposure of livestock to high temperatures.• Knowledge gaps include an understanding of climate change impacts on growth and nutritional value of vegetable and fruit crops, the dynamics of pests and diseases, and direct and indirect effects (the latter via pasture growth) on livestock and livestock-crop systems.• New experiments and development of modeling and analysis tools are needed for many of the economically-important agricultural systems in order to better estimate climate change impacts on Florida's diverse agricultural production systems.
