| Summary: | 碩士 === 國立中興大學 === 森林學系 === 87 === This study was Schima superba var. superba and Gordonia axillaris phenological observation at Hue-Sun Forest station,Nan-tou County. Showed annual variation of phenomenon in leaf production and loss, flowering, and fruiting. Collected flower bud and fruit from tip of the branchlets and observed the development of flower bud by SEM. After fruits of Schima superba var. superba were ripe, collected the seeds from different mother tree for germination test. The result obtained may be summarized follow: Schima superba var. superba produced new leaves between April and May. Flowering period was during June and July. Ripe fruits were found in November and December. The peak of seeds fell after fruits had ripen between November and February. Gordonia axillaris flushed in March and April. Ripe fruit may be found between March and November. The peak of loss aged leaves during March and April.
These two species are belong to polystemonous flowers. The numbers of stamens in Schima superba var. superba and Gordonia axillaris flowers are about 95 and 150. In early floral development, sepal primordias were first initiated. At the middle stage, the stamen primodias were developed. Stamen primordias continued to expand, the carpel were last initiated. There were psuedopollen grains in the connective of Schima superba var. superba, but there was no one in Gordnia axillaris. Germination rate would become higher after stratification. But it would become lower on different date the seed fell.
