Abstract:

Pineapple [Ananas comosus (L.) Merr.] is one of the most important commercial fruit crops of the family Bromeliaceae in the world. In pineapple, irregular flowering behaviour is observed and sometimes even after 18 months of planting less than 50% of flowering occurs and unnecessary delay may be observed. Paclobutrazol (PBZ), a triazole plant growth regulator which inhibits gibberellin biosynthesis has been effectively used to induce and manipulate flowering, fruiting in several perennial fruit crops. To evaluate effect of paclobutrazol on flowering characteristics of Pineapple cv. Mauritius, the present experiment was conducted in instructional farm of Pomology and Post-harvest Technology, UBKV, Pundibari during 2016-2018. Paclobutrazol (PBZ) concentrations ranging from 100ppm to 300ppm were used in seven different treatments. Paclobutrazol @100ppm applied 8 months after planting (T1) resulted in the lowest number of days (55.32 days) for red heart initiation. Lowest duration to produce 50 per cent flowering was also seen in T1 (67.26 days).
