Development of the cuticular wax during growth of Kalanchoe daigremontiana (Hamet et Perr. de la Bathie) leaves

The goal of the present study was to monitor cuticular wax accumulation during leaf development of Kalanchoe daigremontiana. Leaves expanded linearly until they were 40-60 d old. Wax coverages of leaves on the third node increased steadily during initial leaf development, from 6.5 microg x cm(-2) on day 22 to 15.3 microg x cm(-2) on day 53, and then levelled off. Triterpenoids dominated the wax mixture throughout leaf development, but decreased …
