Abstract : The effects of 7 bark inversion treatments varying in width (0.5-1.5 cm) and circumference (75% or full circumference) of bark ring on 2-week-old mango seedlings were assessed in trials in 1991-93 and 1992-94 at Vanaras, Uttar Pradesh, India. All the bark inversion treatments effectively induced the attributes essential for dwarfing of mango plants during the initial stages of growth. Inversion of a 1.5 cm wide full ring of bark during 1991-93 and 1992-94 resulted in the lowest plant height (61.93 cm and 56.80 cm), length of terminal sprouts (36.25 cm and 33.02 cm) and number of flushes (5.97 and 4.62) in each trial, respectively, and the highest number of sprouted axillary buds (6.47 and 6.30), longest axillary sprouts (37.92 cm and 36.96 cm) and greatest stem circumference of plants above the inverted bark portion (19.81 cm). The corresponding data for control plants (without bark inversion) were plant height - 83.55 cm and 77.29 cm, number of sprouted axillary buds - 5.85 and 4.62, length of axillary sprouts - 30.82 cm and 32.85 cm, length of terminal sprouts 44.10 cm and 42.95 cm, number of flushes - 6.56 and 5.50 and circumference of plants 16.32 cm and 16.85 cm during 1991-93 and 1992-94, respectively.
