Abstract
M.Sc. (Botany)
The purpose of this investigation was to determine the
following:
(i) The effect of water loss by transpiration on the
browning of foliage of Protea neriifolia.
(ii) Microscopic characteristics of leaves and stems
of different P. neriifolia variants.
(iii) A comparison of the vase and postharvest life
of several P. neriifolia variants.
(iv) The concentration of leuco-anthocyanins (brow=
ning components) in individual leaves situated
on different locations on peduncles of diffe=
rent P. neriifolia variants.
Protea repens was included in some investigations since this
species is less subjected to browning of foliage.
