Response of Milkweed Species to Light Levels
Seedlings of identified species grown at varying light intensity for 8 to 12 weeks; photosynthetic rates, stomatal conductance rates, and transpiration rates measured.
Response of Milkweed Species to Nitrogen
Identified species grown for 8 to 12 weeks at three levels of Hoagland solution (zero, half, and full concentration); plants 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.
