It was the purpose of this experiment to determine the relationship between the factors of pulvinus temperature and light intensity in their role as factors that affect paraheliotropism. We also examined the differences in these relationships in two species adapted to different environments. The two species used were: Phaseolus vulgaris (common bean), a high yielding species which is grown in mesic climates, and P. acutifolius (tepary bean), an arid land bean which tolerates high temperatures and drought.
