Abstract:
Objective To find out evidence for the identification of the aerial roots of Ficus microcarpa Linn. f. and F. altissima Bl.. Methods The fresh aerial roots of the two kinds of plants were collected. The appearance traits were observed by stereoscopy. The velamen surface, cross section of root tip, cross section of the posterior root and powder of two kinds of aerial roots were observed under microscope. Results The number of aerial roots of F. microcarpa Linn. f. was more than that of F. altissima Bl., while the diameter was less than that of F. altissima Bl.. Differences were shown in primary xylems of the transverse section of root tip and posterior root of the two kinds of aerial roots, there were 5-7 vascular bundles in F. microcarpa Linn. f. and 7-10 vascular bundles in F. altissima Bl.. As for the powder, the powder of F. microcarpa Linn. f. was yellowish brown, while that of F. altissima Bl. was reddish brown; F. altissima Bl. had more fibers and longer diameter than F. microcarpa Linn. f. and had cluster crystals in order. Conclusion The appearance and microstructure features showed by the results can be used to distinguish the aerial roots of F. microcarpa Linn. f. and F. altissima Bl..
