Farrant, Jill M Van der Willigen, Clare Botany Bibliography: leaves 92-100. Xerophyta humilis is a resurrection monocot that is able to survive drying of its tissues to an air-dry state. in order to assess the alidity of laboratory-based experimentation, and the results obtained from such studies, a comparison of aspects of X. humilis physiology under different environmental conditions was undertaken. Analyses of chlorophyll fluorescence, gas exchange parameters, pigment concentrations and electrolyte leakage were performed on plants dehydrated under laboratory conditions differing with respect to light intensity ("high light" (ca. 1400 ųmol.m-². s-¹) and "low light" (ca. 400 ųmol. m-². s-¹)). Physiological parameters were also examined during rehydration under high and low light laboratory conditions, and natural field conditions. Plants maintained fully hydrated for some time were also examined under laboratory conditions for the occurrence of rhythmic patterns in their daily physiology, and for any evidence of acclimatisation to the different environments. 2014-09-29T07:28:20Z 2014-09-29T07:28:20Z 2002 Master Thesis Masters MSc http://hdl.handle.net/11427/7724 eng application/pdf Department of Biological Sciences Faculty of Science University of Cape Town |
