Abstract

Abstract: Nitrogen deposition plays an important role in shaping the physiological and ecological characteristics of plants. The photosynthetic characteristics of plants in different canopy may respond differently to nitrogen deposition, however the effects remain unclear. By addition urea in Inner Mongolia grassland, we studied the responses of net photosynthesis rate (P_n), water use efficiency (WUE), transpiration rate (Tr), stomatal conductance (G_s) and biomass of two dominant species (Leymus chinensis represents the upper layer species, Carex korshinskyi, represents the lower layer species) to nitrogen deposition. The results showed that P_n of L. chinensis increased with the increase of nitrogen addition, however decreased when the N addition rate above 1.6 mol·m^-2. P_n of C. korshinskyi increased with the increase of nitrogen addition constantly. Nitrogen addition increased the WUE, biomass and relative biomass of L. chinensis, but did not affect the WUE, biomass and relative biomass of C. korshinskyi. The G_s and Tr of C. korshinskyi were significantly higher than those of L. chinensi when the nitrogen addition rate was higher than 0.8 mol·m^-2 (P<0.01). Tr of C. korshinskyi increased with the increase of nitrogen addition, however G_s and Tr of L. chinensis showed no clear pattern. Our results indicated that P_n of lower canopy plant increased constantly with the increase of N addition, implying that the upper plant may have no restrictions on the photosynthesis of the lower plant in arid and semi-arid grasslands.

Key words: nitrogen deposition, typical steppe, net photosynthetic rate, water use efficiency, transpiration rate, stomatal conductance
