Effect of CO₂-concentration on the Morphological, Histological and Cytological Changes in Tomato Plants

Interaction of Elevated CO2 and Ozone Concentrations and Irrigation Regimes on Leaf Anatomy and Carbohydrate Status of Young Oak (Quercus petraea) Trees

“…How ever, the latter may be due to the morphometrical methods used. These results match the scanty re ports on effects of elevated C 0 2 concentrations on leaf anatomy of woody or herbaceaous C3 plants (Madsen, 1973;Thomas and Harvey, 1983;Vu et al, 1989;Radoglou and Jarvis, 1990). In these studies, an increase in mesophyll thickness was also observed.…”

In situ Photosynthetic Responses to Light, Temperature and Carbon Dioxide in Herbaceous Plants from Low and High Altitude

“…Exposure of plants to low CPA reduced leaf thickness of greenhouse plants (Madsen, 1973). However, alpine plants exhibit thicker assimilatory tissues (high in nitrogen) which favour higher rates of CO2 uptake per unit leaf area (Nobel & Walker, 1985).…”

Reconstructing atmospheric carbon dioxide with stomata: possibilities and limitations of a botanical pCO2-sensor

“…It has long been known that under greenhouse conditions, plants can decrease their stomatal density under elevated levels of pCO 2 (Madsen 1973;O'Leary and Knecht 1981;Thomas and Harvey 1983). Since Woodward (1987) described how stomatal densities (number of stomata per area, usually expressed per square millimeter) changed with increasing pCO 2 by considering both herbarium material and experimental results, stomatal frequency appears to represent a valuable device for reconstructing past pCO 2 .…”
