Responses of beech and spruce foliage to elevated carbon dioxide, increased nitrogen deposition and soil type.

Günthardt-Goerg MS, Vollenweider P - AoB Plants (2015)

Bottom Line: This study compared reactions in the foliage of a deciduous and a coniferous tree species (important central European trees, beech and spruce) to an elevated supply of CO2 and evaluated the importance of the soil type and increased nitrogen deposition on foliar nutrient concentrations and cellular stress reactions.The magnitude of the effects varied among the tree origins in both species.The soil type and its nutrient supply largely determined the fertilization gain, especially in the case of beech trees with a narrow ecological amplitude.

The change in the concentration of photosynthetic pigments in July (A and B), namely chlorophyll a + b and α + β carotenoids (hatched columns), and in the leaf colour in September (C and D) in response to +CO2, +ND and +CO2 + ND versus control, within the foliage of several origins of beech growing on either acidic or calcareous forest soil (mean values + SE, N = 4). Photographs (E) show typical examples of leaf discolouration in response to elevated CO2.

PLV067F2: The change in the concentration of photosynthetic pigments in July (A and B), namely chlorophyll a + b and α + β carotenoids (hatched columns), and in the leaf colour in September (C and D) in response to +CO2, +ND and +CO2 + ND versus control, within the foliage of several origins of beech growing on either acidic or calcareous forest soil (mean values + SE, N = 4). Photographs (E) show typical examples of leaf discolouration in response to elevated CO2.

Mentions: Exposure to +CO2 affected the photosynthetic pigment content and leaf colour of beech leaves, and this latter parameter varied as a function of the nitrogen supply and soil type. The leaf chlorophyll and carotenoid concentration on both soils was decreased in July by +CO2 by 30 and 20 %, respectively, whereas +ND caused no significant change (Fig. 2A and B, Table 1). In September, the colour of beech foliage showed over the experimental years lighter green hues in the +CO2 treatment (−5 % on calcareous, −11 % on acidic soil, Fig. 2C–E) whereas +ND led to darker green hue on acidic soil (+6 % Fig. 2D, Table 1). Accordingly, the N concentration in leaves was on average decreased by +CO2 (−11 %) but enhanced by +ND (+8 %; Fig. 3A and B, Table 1). Beech trees growing on the acidic versus calcareous soil also displayed an overall lighter green colour (−6 %, Fig. 2D versus C). An effect by the plant origin in the leaf chlorophyll content in July was transient, the differences levelling off by September.Figure 2.
