“…In addition, the sodium chloride crystals that accumulate on the leaf surface can increase refl ectivity, protecting the epidermis against excessive light (Uchiyama and Sugimura, 1985;Karimi and Ungar, 1989;Rajput and Sen, 1991), which may explain the presence of Na and Cl in the crystals deposited in the trichomes that protect the areola meristems in species of Cephalocereus. Furthermore, several authors (Conde, 1975;Darling, 1989) point out that the crystals help to reduce evaporation or increase refl ectivity, as well as to decrease transmittance. This may occur in the fi ve species of Cephalocereus; growing in TRICHOMES WITH CRYSTALS IN THE CEPHALOCEREUS PFEIFF.…”

“…Nos cactos "não-pereskia", os quais dependem da realização da fotossíntese no sistema caulinar, o sistema de revestimento predominante no ápice e na região mediana é a epiderme (Gibson & Horak 1978, Mauseth 1996, 1999. Nestes cactos a epiderme permanece funcional por décadas, controlando as trocas gasosas necessárias à realização do processo fotossintético (Darling 1989).…”

“…Em Austrocylindropuntia subulata, Opuntia rufida e O. monacantha a epiderme apresenta aspecto plano com os estômatos situados no mesmo nível das demais células epidérmicas (figura 1a) em todas as regiões analisadas, corroborando o mencionado por outros autores para Cactaceae (Conde 1975, Eggli 1984, Darling 1989, Calvente et al 2008. Esta localização superficial dos estômatos, provavelmente, favorece rápidas trocas gasosas durante sua abertura, podendo representar uma adaptação ao mecanismo fotossintético CAM (Gibson & Horak 1978, Gibson & Nobel 1986).…”

“…O tecido subepidérmico tem recebido diferentes denominações, sendo em geral descrito como hipoderme colenquimatosa (Metcalfe & Chalk 1950, Conde 1975, Gibson & Nobel 1986, Darling 1989, Fahn & Cutler 1992, Silva & Alves 1999. Em Cipocereus minensis (Wederm.)…”

“…Segundo Darling (1989) e Fahn & Cutler (1992 a localização destas câmaras assegura rápidas trocas gasosas logo após a abertura dos estômatos, aumentando assim a eficiência fotossintética.…”
