    Opis:
    Rootability of Dalbergia sissoo Roxb. cuttings of mature tree originated clonal hedge bed were tested and compared to the same from seedling originated hedge bed. Mature tree originated cuttings were found potential for rooting in low-cost non-mist propagator without any rooting hormone. Steckling growth in nursery and in the field was found promising which is a complete indication for its successful application by tree planters. It will be a new research avenue to get disease free germplasm for the frustrated plantation managers and scientists due to die back of this tree through out the South Asian region.

    Opis:
    Anisoptera scaphula (Roxb.) Kurz, the tallest tree species in Bangladesh, is critically endangered worldwide due to its poor natural regeneration. This study describes the appropriate regeneration technique for A. scaphula through seed germination and clonal propagation by stem cutting. The fastest and highest germination percentage (65) was observed in dewinged seeds sown inverted orientation with half buried position (T10) followed by dewinged seeds (62.5%) sown horizontally in full buried (T7) and delayed germination with lowest percentage (15) was in control (T0). Optimum initial growth was also shown when seedlings were developed from the seeds under T7. Both winged and dewinged seeds sown vertically in full buried or half buried position produced curved seedlings. However, dewinged seeds sown in horizontal or inverted (winged side down) position produced otherwise i.e., straight seedlings. The highest rooting percentages (63%) and maximum number of root (4.8) per cutting were obtained when one node cuttings treated with 0.8% IBA solution followed by 0.4% IBA in turn affecting for better survival and growth of rooted cuttings in the nursery conditions.

    Opis:
    The study was carried out to investigate the domestication potential of Flacourtia jangomas (Lour.) Raeusch, a wild fruit species in Bangladesh, through nursery raising from seeds and clonal propagation by stem cutting. Air dried seeds were treated with four different pre-sowing treatments i.e., control (T0), seeds soakedin coldwater for 24 h (T1), 48 h (T2), or 72 h (T3) to explore the seedgermination ability of the species. Pre-sowing treatments significantly enhancedthe germination period, germination percentage andbiomass production of seedlings. The early germination (least imbibition period), highest germination percentage (81.3) and total dry biomass (0.52 g) was observed in T2 (seeds soaked in cold water for 48 h) while the lowest germination percentage (53.7) andtotal dry biomass (0.23 g) was observedin T3 andT0 respectively. The plant species was highly amenable for rooting for clonal propagation. However, the rooting ability of cuttings was significantly affectedby the application of IBA. The highest rooting percentage (100), maximum root number (5.63), the longest root length (3.28 cm) andbest survival (85.0%) were obtainedfrom the cuttings treatedwith 0.4% IBA solution followed by 0.2% IBA andthe lowest was in cuttings without treatment. Therefore, pre-sowing treatment ‘soaking of seeds in cold water for 48 h for nursery raising and ‘0.4% IBA treatment’ of stem cuttings for clonal propagation may be recommended for mass production of quality planting stocks for the domestication of the species through homestead agroforestry or in fruit orchards.
