Abstract
In the field C. wilmsii (homoiochlorophyllous) and X humilis (poikilochlorophyllous) plants do not experience drought longer than two and six months, respectively. In this study longevity of dry C. wilmsii and X. humilis plants was investigated for up to 10 months under four different sets of conditions. Some conditions resembled those under which the two species would experience drought in the field, but also included those that resemble the accelerated aging conditions used in seed studies.
