Abstract

Growth patterns under controlled conditions and chemotaxonomic techniques involving protein and flavonoid analysis were used to investigate both interpopulational and species comparisons in the genus Liquidambar. Striking differences in budburstinq patterns after a dormant period were seen when comparing L. styraciflua and L. formosana. The latter species showed earlier initiation of growth. Dormancy patterns of L. styraciflua grown under growth chamber conditions showed a latitudinal cline. Cessation of growth occurred later in a Georgia population under both long and short day experimental periods than populations from Missouri and Kentucky. When grown under controlled conditions, flavonoid patterns from L. styraciflua and L. formosana showed few differences. Differences in flavonoid patterns were suggested when comparing the North American L. styraciflua and a single leaf sample of L. orientalis from Turkey. Extensive trials attempting to examine protein banding patterns by electrophoretic methods were unsuccessful even though the techniques have been used successfully in examinations of other plants.
