Abstract

Abstract: The physiographical factors, the communityps components and morphological characteristics of sweet osmanthus (Osmanthus fragrans) community were studied by two surveys at Zhouluocun in Hunan. Based on the field investigation, the biological characteristics of sweet osmanthus population were analysed; interestingly, morphological variations of flowerwere found. The results show that the color of sweet osmanthus corolla ismainly either light yellow ormilk yellow, but occasionally aureate or snow2white individuals can be
found due to genetical variation in this Zhouluocun community. Flower types of sweet osmanthus are bisexual flower or unisexualmale flower due to the degeneration of p istil. Our data demonstrate that there are abundant morphological variations and successful regeneration in the natural population of sweet osmanthus.
