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 dry mass of single leaves (A and B) and total crown foliage (C and D) in beech in response to +CO2, +ND and +CO2 + ND versus control for several origins (Aar, Aarburg; Her, Herzogenbuchsee; Hir, Hirschtal; Sih, Sihlwald) growing together on either acidic or calcareous forest soil (mean values + SE, N = 4, September harvest).

PLV067F1: The change in the dry mass of single leaves (A and B) and total crown foliage (C and D) in beech in response to +CO2, +ND and +CO2 + ND versus control for several origins (Aar, Aarburg; Her, Herzogenbuchsee; Hir, Hirschtal; Sih, Sihlwald) growing together on either acidic or calcareous forest soil (mean values + SE, N = 4, September harvest).

Mentions: The treatments changed the morphology of beech leaves and their effect varied as a function of the soil type and plant origin. Over the three vegetation periods, the dry leaf mass (Fig. 1A and B), area and thickness of single leaves were increased by 12, 7 and 6 % on average in response to +CO2 on the calcareous soil, whereas on the acidic soil they were significantly increased by +ND (11, 8 and 6 %, significant treatment × soil interaction, Table 1). Total leaf mass was only increased by ND by 30 % on acidic soil, but unchanged by +CO2. The soil type had a strong influence on the leaf-level response to +CO2 and the leaf mass, area, thickness and LMA were by 17, 10, 7 and 9 % lower, respectively, on the acidic versus calcareous soil, whole-tree foliage mass even by 62 % (Fig. 1C and D, Table 1). With significant differences between origins, the leaf water content was on average 4 % lower in September than in July (whilst the LMA showed no change) but was not responsive to the treatments. In contrast to the dry leaf mass and area (<8 % difference among the origins) and related to initial seedling age, the total foliage dry mass by the end of experiment showed a doubled biomass of Her and Sih compared with Aar and Hir on the nutrient-rich calcareous soil (Fig. 1C, Table 1).Table 1.
