Abstract:
A resilient fruit tree with the chromosomal number 2n = 48, the ber (Zizyphus mauritiana Lamk.), is a member of the Rhamnaceae family. It may be produced successfully in dry and semi-arid regions of Indian states, including Haryana, Rajasthan, Madhya Pradesh, and Gujarat. Since there is no standardized protocol for the propagation of apple ber in Andhra Pradesh region, the current experiment was conducted with objectives of finding out the best type of rooting media, IBA concentrations and methods of application for successful propagation. The terminal cuttings were planted in three types of media viz., coco peat, vermiculite and saw dust, which were treated with three different concentrations of IBA i.e., 1000 ppm, 1500 ppm and 2000 ppm. For application, two methods were followed i.e., cuttings treated with mixture of IBA and talcum powder and cuttings treated with IBA solution for 5 minutes. The result of this experiment showed that the maximum chlorophyll content (46.07 SPAD unit), absolute growth rate (0.35 cm /day) and early achievement of plantable size of propagules (97.66 days) was observed when the terminal cuttings were treated with 1000 ppm of IBA for 5 minutes and propagated in coco peat.
