Results and Discussion
Table 1 shows the effects of elevated CO2 concentration and temperature on fruit characteristics of ‘Niitaka’ pear. Among the treatments, fruit weight was highest in elevated CO2 treatments at 543.0 g, and lowest at 394.3 g in elevated temperature treatments. This was generally consistent with the fruit longitudinal/equatorial diameter, thereby confirming that fruit weight and fruit volume increase under high CO2 concentration.
