Popis:	Gross primary production (GPP), transpiration and c onversion efficiency of solar energy by Artemisia sieberi and Artemisia aucheri in Nodushan shrublands of Yazd, Iran, were determined. GPP was determined through estimates of net primary pro duction (NPP) and respiration (R) of leaf, new branch, stem, coarse root and fine root. Total biom ass (g C m -2 ) of A.sieberi and A.aucheri was 81.7 and 224.87 respectively. The ratio of below-to-abovegro und biomass was 0.4 and 0.56 respectively, for A.sieberi and A.aucheri. Total NPP, R and GPP (g C m -2 ) were 32.11, 53.1 and 85.21 for A.sieberi and 62.75, 91.56 and 154.31 for A.aucheri. The carbon u se efficiency (NPP/GPP), R/GPP and Belowground NPP/total NPP were 0.38, 0.62 and 0.29 for A.sieber i and 0.41, 0.59 and 0.37 for A.aucheri respectivel y. Based on the estimates of solar energy available in the study sites, the amount of incoming solar ener gy absorbed in photosynthesis and transpiration was 0. 05 % and 0.08 % by A.sieberi, and 0.08 % and 0.17 % by A.aucheri. Artemisia shrublands play an important role as carbon sinks and energy stocks in arid an d semiarid ecosystems of the central parts of Iran.
