The lotus effect and the transpiration

Postby jakov03 » Tue Nov 03, 2009 1:13 am

Hi! I need an urgent response to a question. I know for a hydrophobic effect on the surface of lotus flower(precisely: the surface of the leaf), but me interest how is conducted the transpiration by this flower given the superhydrophobic effect. Thank you!

why should hydrophobicity affect transpiration? as I recall, transpiration uses pores.

The water repelling wax on the leaf will effect liquid water droplets but transpiration through stomata (pores) is a process where water vapour is lost - the vapour doesn't go near the water repelling surface so it's not relevant.
