Extent of solar tracking differs between two co-occurring congeneric geophytes that differ in leaf shape

Mocko, Kerri; Nicotra, Adrienne; Jones, Cynthia


Premise of research. By adjusting leaf angles to orient toward or away from the sun, solar tracking modifies direct light interception, which consequently modifies leaf temperature. Leaf temperature is also influenced by leaf shape, due to its effect on heat transfer across boundary layers. Two co-occurring, closely related geophytic species of Pelargonium that differ dramatically in leaf shape were observed to exhibit differences in diurnal leaf movements. We asked whether leaf movements were...[Show more]
