ABSTRACT

An experiment was conducted in the Abloom flora of Gunjanagar-5, Chitwan, Nepal during March, 2013 to August, 2013 to study the effect of Spring Pruning on Growth and Production of Quality Cut Flower of HT Rose Cultivars. The experiment was laid out in three factorial split- split plot design with three replications. There were 12 treatments consisting of three popular Italian HT Rose varieties (High Magic, Lenopa and Confetti of three different color viz white, red and yellow respectively), two dates (1st on 8th March, 2013 and 2nd on 18th March, 2013) and Pruning (Pruned and nonpruned). High Magic pruned on 8th March 2013 produced flower having longest floral bud (3.554cm) and flower stem (41.008cm). Maximum flower diameter (2.863cm) was also recorded in High Magic pruned on 8th March, 2013. High Magic also produced larger mean number of cut rose flowers (23.833) followed by Confetti (14.250) and Lenopa (10.333) . Plants pruned on 1st date produced maximum mean number of flowers (20.889). Maximum (22.611) flowers per plot was counted in pruned plants. Among all cultivars, High Magic produced longer stem length in all dates of pruned and un-pruned condition followed by Lenopa and shorter stem length was produced by variety Confette in all conditions. Variety High Magic pruned on 18th March 2013 produced longer flower stem (44.750cm) whereas variety Confetti produced flowers having shorter stem length (24.333cm) in plants that were un-pruned on 8th March, 2013.
