TY - Data T1 - Photosynthetic characteristics of Populus euphratica in the lower reaches of Tarim River from 2000 to 2007 A1 - Chen Yaning DO - 10.12072/ncdc.NIEER.db0026.2020 PY - 2021 DA - 2021-01-06 PB - National Cryosphere Desert Data Center AB - Main monitoring indicators: net photosynthetic rate (PN), transpiration rate (TR), stomatal conductance (GS) and other gas exchange parameters were measured, At the same time, atmospheric CO2 concentration (CA), intercellular CO2 concentration (CI), photosynthetically active radiation (PAR), atmospheric temperature (TA), leaf surface temperature (TL), air relative humidity (RH) and other parameters were measured, and each leaf was read three times. WUE = pN / TR, LS = 1 - CI / ca. DB - NCDC UR - http://www.ncdc.ac.cn/portal/metadata/462a5834-99d8-4172-8421-6785b513e379 ER -
