The ontogeny of hairs and stomata of cabomba australis nymphaeaceae

, : The ontogeny of hairs and stomata of cabomba australis nymphaeaceae. Lilloa 35(3): 149-158

Floating and submerged leaves of this were studied. Hairs are restricted to the lower epidermis; they are tetracellular. The apical prominent cell disappears in mature leaves. These hairs protect young organs by mucilage secretion. Anomocytic stomata are uniformly scattered over the upper surface of floating leaves. In submerged leaves, stomata are present only in the lower epidermis near the vein endings; they probably act as hydathodes. On the upper epidermis of the same leaves are numerous tannic-mucilage cells.

To determine the effect of the calcium blocker amlodipine on the variability of mean arterial pressure (MAP), amlodipine besylate was acutely administered to sino-aortic baroreceptor-denervated (SAD) rats (0, 1, 3, 10 mg/kg s.c.), and chronically...
