摘要

青剛櫟、赤皮、森氏櫟與高山櫟等四種殼斗科樹種種子被用來研究種子之儲藏性質。四種種子均顯示含水率愈低，種子之壽命愈短，因此均屬於異儲型的種子。四種種子在低溫濕藏下至少可保存一年之壽命。青剛櫟與高山櫟二者之新鮮種子並未顯現休眠現象，其中青剛櫟的種子在層積儲藏至8個月時開始自行發芽，高山櫟層積約在3個月時開始發芽。而森氏櫟與赤皮二者之新鮮種子具有休眠現象，二者在一年低溫層積儲藏期間並未有自行發芽的現象。

The seeds at four species of Fagaceae, i. e., Cyclobalanopsis gilva (Bl.) Oerst., C glauca (Thunb.) Oerst., C. morii (Hay.) Schott. and Quercus spinosa A. David were used to study the storage behavior. Seed viability decreased of these four species more rapidly at lower moisutrc content than at higher mois-ture content. Therefore, the seeds belong so the recalcitrant seed type.
At cold wet storage seeds maintained the viability for at least one year. Fresh seeds of C. glauca and Q. spinosa didn't show dormancy. C. glauca began to germinate after eight months and Q. spinosa started to germinate about three months at wet storage. Fresh mature seeds of C. gliva and C. morii showed dormany that could be overcame by cold stratification. No presprouting was observed for the two latter species at cold wet storage for at least 12 months.
