摘要

Justicia adhatoda L.（Bashak）是一种常绿药用灌木，属于刺桐科。该物种的种子萌发质量很差。本研究评估了IAA、IBA和NAA等辅助剂对该植物茎插条的影响。按照完全随机设计，共对茎插条进行了 13 种处理，并将其种植在沙床中。结果表明，用 IBA 1000 ppm 溶液处理的插条在插后 90 天的根数（28.67）、根长（14.10 厘米）和生物量（12.78 克）均最大。而用 IAA 和 NAA 1000 ppm 溶液处理的插条在插后 90 天分别获得了根数（21.67 和 22.67）、根长（11.30 和 15.17 厘米）和生物量（8.56 和 12.17 克）。IBA 1000 ppm 溶液最适合在 90 DAP 时产生最多的根和生物量，NAA 1000 ppm 溶液最适合在 90 DAP 时产生最多的根长。孟加拉国植物学报52(3):861-865，2023 年（9 月）

Effects of auxins on the stem cuttings of Justicia Adhatoda L.

Justicia adhatoda L. (Bashak) is an evergreen, medicinal shrub belongs to the family Acanthaceae. The seeds germination quality of the species is very poor. The effects of auxins viz. IAA, IBA and NAA on the stem cuttings of the plant were assessed. A total of 13 treatments were applied on the stem cuttings and planted in sandy bed following completely randomized design. Results revealed that the maximum number of roots (28.67), length of roots (14.10 cm) and biomass (12.78g) were obtained at 90 days after planting in the cuttings treated with IBA 1000 ppm solution. Whereas, number of roots (21.67 and 22.67), length of roots (11.30 and 15.17 cm), biomass (8.56 and 12.17g) were obtained at 90 days after planting in the cuttings treated with IAA and NAA 1000 ppm solution respectively. IBA 1000 ppm solution would be considered as the most suitable for producing maximum number of roots and biomass, as well as NAA 1000 ppm solution for length of roots in Bashak at 90 DAP.

期刊介绍： Bangladesh in situated on the north of Bay of Bengal. Climatically it is a humid subtropical country. Most of the land is deltaic plain of two great rivers, the Ganges and the Bhrammaputra and it tributaries. The country has rich diversity of plants. Main crops cultivated are Rice, Jute, Wheat, Maize, Sugarcane, Mustard and different kinds of Lentils. There are a good number of Public and Private Universities and Plant Research Establishments. Bangladesh Journal of Botany is the official organ of the Bangladesh Botanical Society established in 1972. Since 1972 Bangladesh Journal of Botany is being published regularly. Two issues of the Journal are published, one in June and another in December. Scientific papers (Full paper and short communication) on any field of Plant Sciences from anywhere in the World are considered for publication in Bangladesh Journal of Botany.
