title: Epicuticular Lipid Accumulation on the Leaves of Lycopersicon pennellii (Corr.) D'Arcy and Lycopersicon esculentum Mill.
abstract: A comparison was made of epicuticular lipid accumulation on leaves of Lycopersicon pennellii and Lycopersicon esculentum Mill. cv VF36 from 5 to 16 weeks of age. Epicuticular lipids were a small fraction of the leaf dry weight (0.16%) of 5-week-old ;VF36', and increased to only 0.96% of the leaf dry weight after an additional 12 weeks of growth. In contrast, leaves from 5-week-old and 17-week-old L. pennellii plants had, respectively, 0.94% and 19.9% of their total dry weight in epicuticular lipid. Lipid accumulation was not affected by drought stress. Leaf position appears to influence the amount of lipid on the leaf surface. A glycolipid appears to be exuded from the terminal cell of glandular trichomes found on the leaves, stems, peduncles, calyxes, and fruits of L. pennellii.
