“…A similar result was reported by Ferris and Taylor (1994), in which stomatal density increased with increasing CO 2 concentrations. The contradictory results from the research done by Uprety et al (2002) and Das (2003) may be due to the different genotypes used in this study. Compared to plants grown under control conditions, increased leaf chlorophyll fluorescence (Fv/Fm) under supplementary lighting conditions was observed in both cultivars, which was similar to the findings of Kim et al (2011).…”

“…Stomatal density, an important eco-physiological parameter that affects gas exchange or the rate of photosynthesis (Uprety et al 2002), can be affected by light intensity (Lake et al 2001), CO 2 -enrichment, or elevated temperature (Uprety et al 2002;Das 2003). In this study, increased stomatal density under supplementary lighting conditions was observed.…”

“…Light intensity (Lake et al 2001) and elevated CO 2 concentrations (Uprety et al 2002;Das 2003) are known to affect various stomatal characters. Among the characters, stomatal density is an important eco-physiological parameter that affects gas exchange or the photosynthetic rate (Uprety et al 2002).…”

However, no experiments have investigated the combined effects of CO 2 and supplementary lighting on plant growth and production in roses.…”

The effects of supplementary lighting with high-pressure sodium (HSP) lamps alone or in combination with carbon dioxide (CO 2 ) on the growth, yield, and flower stem quality of two rose cultivars ('Loving Heart' and 'Top Grace') were studied. Compared to natural lighting (control), supplementary lighting alone was beneficial for plant growth, and it increased plant height, stem diameter, and the number of axillary shoots. Furthermore, increases in flower stem yield (>70 cm), flower stem diameter, fresh weight, and the number of petals per flower were also observed. The combination of supplementary lighting and CO 2 significantly enhanced all of the studied parameters compared to supplementary lighting alone. Moreover, stomatal density and chlorophyll fluorescence were seemingly affected by either supplementary lighting alone or in combination with CO 2 . This is the first study to examine the beneficial effects of combined supplementary lighting and CO 2 conditions, and the resulting information is essential to rose growers and commercial production.

“…Periods of relatively low atmospheric CO 2 concentration in prehistory are characterized by high densities of small stomata, whereas periods of CO 2 concentration much higher than present levels are characterized by low densities of larger stomata [5]. Recent experimental evidence also supports this inverse correlation between CO 2 concentration and S [17][18][19]. S determines two important physical dimensions contributing to g c(max) and g w(max) : the maximum area of the open pore (a max ), and the pore depth or diffusion path length (l ).…”

To investigate the impact of manipulating stomatal density, a collection of Arabidopsis epidermal patterning factor (EPF) mutants with an approximately 16-fold range of stomatal densities (approx. 20–325% of that of control plants) were grown at three atmospheric carbon dioxide (CO 2 ) concentrations (200, 450 and 1000 ppm), and 30 per cent or 70 per cent soil water content. A strong negative correlation between stomatal size ( S ) and stomatal density ( D ) was observed, suggesting that factors that control D also affect S . Under some but not all conditions, mutant plants exhibited abnormal stomatal density responses to CO 2 concentration, suggesting that the EPF signalling pathway may play a role in the environmental adjustment of D . In response to reduced water availability, maximal stomatal conductance was adjusted through reductions in S , rather than D . Plant size negatively correlated with D . For example, at 450 ppm CO 2 EPF2-overexpressing plants, with reduced D , had larger leaves and increased dry weight in comparison with controls. The growth of these plants was also less adversely affected by reduced water availability than plants with higher D , indicating that plants with low D may be well suited to growth under predicted future atmospheric CO 2 environments and/or water-scarce environments.
