dc.description.abstractThe study entitled “Effect of pruning level and time on growth and flowering of ornamental climbers” was carried out at Research Farm, Department of Floriculture and Landscaping, Punjab Agricultural University, Ludhiana, Punjab during 2022-2023. The present study was planned with the objective to standardize the pruning time and level of ornamental climbers. The experiment was laid out in split plot design with three replications to study the different pruning time (2) and pruning levels (4 bud stage, 8 bud stage, Tip pruning and control). The optimal pruning time for Adenocalymma alliaceum was late September, that resulted in early bud initiation, bud sprouting, flower bud initiation, and flowering (40.20 days). Plants pruned at the 8-bud stage (L3) took minimum time to leaf bud initiation (22.41 days), leaf bud sprouting, and time to flowering (48.33 days). For Petrea volubilis, late January pruning resulted in minimum time for leaf bud initiation, bud sprouting, leaf sprouting, flower bud initiation, and flowering (47.16 days). In Petrea volubilis pruning at the 4-bud stage was early to leaf bud initiation, bud sprouting, leaf sprouting, and flower bud initiation (45.33 days). In Quisqualis indica, late March pruning leads to the least time for flower bud initiation (46.00 days) and flowering (64.58 days). Leaf bud initiation (5.33 days), bud sprouting, leaf sprouting, flower bud initiation (52.25 days), and flowering (70.83 days) was earliest in plants pruned at 4 bud stage (L2). Pruning at 4 bud stage in Pyrostegia venusta has same trend as in Quisqualis indica with maximum leaf length, width and area.
