The different size of bark removal

The different size of bark removal significantly influenced the days to root appearance in olive propagation through air layering. The highest number of days to root appearance(49) of olive cultivars was recorded at 5 cm bark removal through air layering that were statistically at par with 2 cm (46.00) and 4 cm (39.33) bark removal. However, the lowest number of days (36) was taken by olive plants when 3 cm bark removed from layered branch.
