| Summary: | Crossing between Acacia mangium and Acacia auriculiformis will result Acacia hybrid whether naturally or artificially. Acacia hybrid, as its parents, was developed to support pulp and paper industries. Morphological characteristics of leaves among A. mangium, A. auriculiformis, and its hybrid (A. mangium x A. auriculifomris) were easily differentiated on nursery stage. This study was done to observe the anatomy of root, stem, and leaves of A. mangium, A. auriculiformis, and its hybrid for assessing their similarity. The samples of leaves, stems, and roots were made into semi-permanent object using freehand technique then the results were assessed using an image-raster and leaf clearing. The observed parameters were the anatomical structure in the root, stem, and leaves tissues as well as similarity index among A. mangium, A. auriculiformis, and its hybrid. The result showed that the similarity between A, mangium and A. auriculiformis was 55.26% and its hybrid were closer to A. mangium than A. auriculiformis with similarity index of 60.53%-65.78% and 52.63%-63-16%, respectively. Hybrid vigour showed a closer similarity to intermediate hybrid than inferior hybrid with similarity index of 78.95% and 68.42%. It is a great probability to obtain hybrid vigour by selecting good mother-trees due to the similarity index between hybrid and its mother tree. |
