Song and Huang (2014)

Photosynthesis of second and third most-recently-expanded well watered and fertilized Kentucky bluegrass (cv. 'Baron') leaves of plants growing in pots filled with fritted clay, which they transferred to growth chambers where the potted plants were maintained in air of either 400 or 800 ppm CO2 concentration and subjected to a day/night temperature regime of 25/22C
67%

 

 

Song and Huang (2014)

Photosynthesis of second and third most-recently-expanded well watered and fertilized Kentucky bluegrass (cv.

98%

 

 

Song and Huang (2014)

Photosynthesis of second and third most-recently-expanded well watered and fertilized Kentucky bluegrass (cv. 'Baron') leaves of plants growing in pots filled with fritted clay, which they transferred to growth chambers where the potted plants were maintained in air of either 400 or 800 ppm CO2 concentration and subjected to a day/night temperature regime of 35/32°C
248%

 

 

Van den Berge et al. (2011)

Photosynthesis of well-watered and fertilized mixed grassland plants growing in controlled-environment chambers at the University of Antwerp, Wilrijk, Belgium, under current climate (temperature and CO2 concentration) conditions and future climate (current T + 3C, current CO2 + 230 ppm) conditions with no abnormal soil pollution
