摘要
在福建永安国有林场巨桉无性系种子园中开展了巨桉与柳桉、粗皮桉、赤桉、细叶桉、邓恩桉等树种间和巨桉种内不同无性系间的控制授粉试验。结果表明:桉树控制授粉的成功率与树种密切相关,其中巨桉种内和巨桉与柳桉、粗皮桉的授粉成功率较高,与细叶桉、赤桉、邓恩桉的授粉成功率较低;授粉方式以一次性授粉为宜。
Some inter-species and intra-species controlled pollinations have been conducted in the grafted seed orchard of Eucalyptus grandis in Yong＇an National Forest Farm of Fujian province, using pollens of E. pellita, E. can,aldulensis, E. dunnii, E. saligna and E. tereticornis. The pollinating efficiency was closely related with the pollen tree species, of which the better result was attained in intra-species pairs, E. grandis × E. saligna or E. pellita and the poorer in E. grandis× E. tereticornis, E. grandis ~ E. camaldulensis and E. grandis × E. dunnii. AlP pollinating method was tested as more suitable for control-pollination in E. grandis compared to another method.
