- Abstract
There is a close relationship between crassulacean acid metabolism and drought tolerance, and a great number of landscape plants which consume less water are necessary to build economic garden. In order to provide the basis for selecting drought- tolerant landscape plants, five species of plants were employed, including Dendrobium chrysotoxum, D. nobile, D. primulinum, Kalanchoe blossfeldiana ad K. daigremoaiana. Exposed to different intensities of light, various samples were collected. The slices were prepared via different techniques. Stomatal movements and stomatal complex structures were observed by scanning electronic microscope and confocal laser scaning microscope. The results indicated that the slices made rapidly from fresh leaves were conductive to inspecting actual stomatal movements and stomatal complex structures as soon as possible. It wa found that the stomatal movement of K. daigremoniana, K. blossfeldiann and D. primulinum displayed typical characteristics of crassulacea acid metabolism, while that of D. chrysotoxum and D. nobile did not exhibited obvious characteristics of cras sulacean acid metabolism.
