Effects of Irradiance on Relative Growth Rates, Net Assimilation Rates, and Leaf Area Partitioning in Cotton and Three Associated Weeds [PDF]

open access: yesPlant Physiology, 1978
Cotton (Gossypium hirsutum L. var. ;Stoneville 213'), velvetleaf (Abutilon theophrasti Medic.), redroot pigweed (Amaranthus retroflexus L.), and hemp sesbania (Sesbania exaltata [Raf.] Cory) were grown in a controlled environment room at 31/25 C day/night temperature and three irradiances: 90, 320, and 750 mueinsteins meter(-2) second(-1).
