title: Potato growth in response to relative humidity.
abstract: Potato plants (Solanum tuberosum L. cvs. Russet Burbank, Norland, and Denali) were grown for 56 days in controlled-environment rooms under continuous light at 20C and 50% or 85% RH.  No significant differences in total plant dry weight were measured between the humidity treatments, but plants grown under 85% RH produced higher tuber yields.  Leaf areas were greater under 50% RH and leaves tended to be larger and darker green than at 85% RH.
