Response of Milkweed Species to Light Levels
Seedlings of identified species are grown at varying light intensity for 8 to 12 weeks, after which photosynthetic rates, stomatal conductance rates, and transpiration rates are measured.
Response of Milkweed Species to Nitrogen
Identified species are grown for 8 to 12 weeks at three levels of Hoagland solution (zero, half, and full concentration), after which plants are harvested for determination of leaf area per plant and dry mass.
Response of Milkweed Species to Drought
Evaluation of the effects of drought (desiccation tolerance) on preferred milkweed species’ growth; data used to plot water potential isotherms.
