摘要
栽培香蕉(Musa spp.)具有复杂的生殖生理特性,这有利于将无性繁殖方法,特别是吸盘或组织培养作为商业方法。通过宏繁殖技术繁殖香蕉可以使用较少的投入生产出优质的种植材料。在此背景下,我们进行了一项科学设计的调查,以优化种植基质的成分,从而生产出低成本的香蕉种植材料。本研究调查了两种香蕉栽培品种使用不同生长基质和生物肥料进行大面积繁殖技术的效果:Grand Naine, AAA "和 "Alpan, AAB"。实验采用完全随机设计(CRD),有 8 种不同的生长基质组合,5 次重复。结果表明,主芽、二级芽和三级芽的萌发以及根系的发育均存在明显差异。由锯末(50%)和香蕉纤维废料(50%)与毛霉菌组成的处理在初芽(21.45 天)、次芽(46.91 天)和三芽(58.99 天)的萌发天数,以及初芽(4.21 天)、次芽(7.16 天)和三芽(19.91 天)的最大数量方面一直优于其他处理。同样的生长介质还记录了最短的生根天数(17.61 天)、最多的每芽生根数(161.10)、一级根(24.89)、二级根(46.32)、三级根(89.90)和最高的根长(21.88 厘米)。与 "Alpan, AAB "相比,栽培品种 "Grand Naine, AAA "在大多数参数上表现更优。总之,用锯屑(50%)和香蕉纤维废料(50%)与毛霉菌混合处理,是生产优质香蕉种植材料、提高香蕉产量和可持续性的一种经济有效的方法。
Unveiling the amalgamation of growing substrates and cultivars for low-cost plantlet multiplication in banana
The cultivated bananas (Musa spp.) have a complex reproductive physiology which favours the vegetative methods of propagation, particularly sucker or tissue culture, as the commercial methods. Propagation of banana through macro-propagation technique can be employed to produce quality planting materials using less inputs. With this background, a scientifically designed investigation was carried out for optimizing composition of growing substrate for low-cost planting material production in banana. This study investigates the efficacy of macro-propagation techniques using different growing substrates and bio-fertilizers for two banana cultivars: ‘Grand Naine, AAA’ and ‘Alpan, AAB’. The experiment was laid out in complete randomized design (CRD) with eight different combinations of growing substrate with five replications. Results showed significant differences in the emergence of primary, secondary and tertiary buds, as well as root development. The treatment comprising sawdust (50 %) and banana fiber waste (50 %) with Trichoderma consistently outperformed others in terms of days taken primary (21.45), secondary (46.91) & tertiary bud emergence (58.99), and maximum number of primary (4.21), secondary (7.16) & tertiary shoots (19.91). Same growing media also recorded minimum days taken for root emergence (17.61 days), maximum number of roots per shoot (161.10), primary roots (24.89), secondary roots (46.32), tertiary roots (89.90) & highest root length (21.88 cm). The cultivar ‘Grand Naine, AAA’ exhibited superior performance across most parameters compared to ‘Alpan, AAB’. Overall, the treatment comprising sawdust (50 %) and banana fiber waste (50 %) with Trichoderma found to be a cost-effective and efficient method for producing high-quality banana planting materials, enhancing banana production and sustainability.
期刊介绍:
The South African Journal of Botany publishes original papers that deal with the classification, biodiversity, morphology, physiology, molecular biology, ecology, biotechnology, ethnobotany and other botanically related aspects of species that are of importance to southern Africa. Manuscripts dealing with significant new findings on other species of the world and general botanical principles will also be considered and are encouraged.
