在实验室条件下,对3种模拟光环境中亚热带常绿阔叶林乔木树种罗浮柿(D iospyros m orrisiana)、香樟(C inna-m omum camphora)、白毛新木姜子(Neolitsea aurata)的种子萌发特性进行了研究,并与同一地区的典型阳性行道树种复羽叶栾树(Koe... 在实验室条件下,对3种模拟光环境中亚热带常绿阔叶林乔木树种罗浮柿(D iospyros m orrisiana)、香樟(C inna-m omum camphora)、白毛新木姜子(Neolitsea aurata)的种子萌发特性进行了研究,并与同一地区的典型阳性行道树种复羽叶栾树(Koelreupena bipinnata)进行了对比。阳生树种复羽叶栾树在各光环境中总萌发率均超过90%,萌发格局表现为前期快,后期平缓;罗浮柿和白毛新木姜子萌发率随着光照水平减弱而升高,白毛新木姜子仅在黑暗中萌发率可达59%,萌发格局表现为整个萌发过程平缓。香樟种子萌发率低,可能与未解除休眠有关。以上结果表明,3种常绿阔叶林乔木和阳性树种复羽叶栾树的种子萌发对光照环境的响应有着显著的差异,这种差异可能与物种的耐阴性、物种原有生境的稳定性和种子的大小有紧密关系。 展开更多

An exploratory study of the traditional homestead forest of two different religious groups (Hindu and Muslim) in one selected floodplain area of Bangladesh was conducted over a period of six months from January to June 2002. The species' (both tree and shrub) preferences, similarities, use and sources of planting materials, spacing and location of species in the homesteads of both Hindu and Muslim communities were studied. It was found thatMangifera indica as tree species andOcimum sanctum as shrub species were the best preferred species of the Hindu community.Artocarpus heterophyllus as tree species andLawsonia inermis as shrub species were found best preferred by the Muslim community. Floristic similarities between the two groups were found 86.57% in tree species and 78.48% in shrub species. Both seed and seedlings of tree and shrub species as planting materials were used by the highest percentage of both the religious communities. For tree species, homegarden was reported to be the highest source (39%) and for shrub species, nature was the highest source (40%), which was found in the Hindu community.
