Propagation of Flacourtia jangomas: an approach

Abstract: 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 soaked in cold water for 24 h (T1), 48 h (T2), or 72 h (T3) to explore the seed germination ability of the spe-cies. Pre-sowing treatments significantly enhanced the germination period, germination percentage and bio-mass production of seedlings. The early germination (least imbibition period), highest germination percent-age (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) and total dry biomass (0.23 g) was observed in T3 and T0 respectively. The plant species was highly amenable for rooting for clonal propagation. However, the rooting ability of cut-tings was significantly affected by the application of IBA. The highest rooting percentage (100), maximum root number (5.63), the longest root length (3.28 cm) and best survival (85.0%) were obtained from the cut-tings treated with 0.4 % IBA solution followed by 0.2 % IBA and the 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 plant-ing stocks for the domestication of the species through homestead agroforestry or in fruit orchards
