摘　　要： 2003-2004年对分布于广东、湖南、江西3省的乐昌含笑果实特征进行观测,结果表明:10月上、中旬乐昌含笑球果成熟度已达81％-96％以上,是采摘的适宜时期;乐昌含笑果形多为球形、卵形,果内含种子数1-7粒不等;果实平均长径1．76-2．62 cm,平均短径1．27-1．73 cm;单株果穗类型分为聚合成串类型,聚合成串、簇生、单生混合型和聚合成串、簇生混合型,以第一类型单株最为普遍,单株最长果穗长度 10-23 cm,其所含果数15-48个;球果平均出籽率8．47％,种子平均千粒重134．7 g。 The fruits of Michelia chapensis Dandy which are distributed in 3 provinces were investigated in 2003 - 2004 years,the results as follows： In the early or middle of october, the degree of maturation of Michelia chapensis Dandy cones were already upwards 81%-96%, it was the towardly period that picking the seeds. Most shapes of Michelia chapensis Dandy fruits were sphericity or oval, containing 1 N 7grain seed. The mean long seg- ment of seed was 1.76 - 2.62 cm, the mean short segment of seed was 1.27 - 1.73 cm. The fruit spike on a tree could be distributed into three types , polymerization cluster, mix of polymerization cluster, fasciation, single, and mix of polymerization cluster, fasciation, the first type was the most. The longest fruit spike was 10 -23 cm, the longest fruit spike contained 15 N 48 fruits. The mean rate of seed output of a cone was 8.47% , the average value of thousand kernels weight was 134.7 g.
