Naturally crossed hybrids ofAcacia mangium x Acacia auriculiformis are found in the A.
auriculiformis and A. mangium plantations of Bangladesh. During 1995 superior hybrid Acacia
trees were selected and propagated by using shoot cuttings for establishing a hedge orchard.
Coppice shoots sprouted from this hedge orchard plants were used as stem cuttings for rooting
trials, and successful cuttings from different clones provided planting materials for clonal trial
experiments. There were highly significant differences between cuttings taken from different
zones of the shoot (cutting types) and hormone treatments in the number of successful cuttings
and number of roots produced per rooted cuttings. Tip cuttings (2 noded) rooted 71.5% and
produced 3.7 roots per rooted cutting when treated with 500 ppm IBA. Similarly, 3rd node cutting
also rooted 80.0% and produced 4.1 roots per rooted cutting under the same treatment. A slight
decrease in rooting success (55.5%) and number of roots (3.2) per rooted cutting were recorded in
4th node cuttings under the same treatment. But percentage of rooting success and number of
roots per rooted cuttings were not increased in the above mentioned three types of cuttings when
treated with higher concentration (1000 ppm or 1500 ppm) of IBA. When a higher concentration
of IBA (1000 ppm) was used in treating 5th node cutting better (50.0%) rooting success and
number of roots (3.3) per rooted cutting were observed. In respect to rooting success and number
of roots produced per rooted cutting the variation between the cuttings of different zone of the
shoot (cutting type) and hormone treatment was highly significant. There were significant
differences between clones in height growth. The highest and lowest height growth were recorded
in clone 2 (87.21cm) and in clone 13 (38.5cm) respectively.
Banspata (Podocarpus nerifolius) is endangered and the only indigenous naturally grown
gymnosperm species in Bangladesh. It is difficult to propagate largely through seed due to its
scarcity in natural forests. Current study shows that macro-clonal propagation technique can be a
tool for raising its propagules for commercial plantation as well as establishment of seed source.
Two types of cutting viz. young green leafy and woody non-leafy cuttings were treated with 300,
500 and 1000 ppm of IBA. In young green leafy cuttings 300 and 500 ppm of IBA treatment
showed better performance in terms of rooting percentage, root development and growth. But, in
woody non-leafy cuttings 500 and 1000 ppm of IBA treatment showed good rooting percentage as
well as root development and growth.
Koroi (Albizia procera) and arjun (Terminalia arjuna) are the two important species
included in the plantation programme in the central part of Bangladesh. Volume tables of these
two species planted in the area have been prepared. These volume tables are applicable for small
and medium sized trees of the respective species planted in the area.
