Standardization of grafting methods under different seasons of grafting in guava (Psidium gujava L.)

Abstract

Experiments were conducted in the College Orchard, TNAU, Coimbatore to standardize suitable grafting method and grafting season in guava for mass multiplication. The research was conducted using three methods of grafting viz., approach grafting (G1), wedge grafting (G2) and side grafting (G3) at three different seasons of grafting viz., Oct-Nov, 2018 (S1), Feb- March, 2019 (S2) and June- July, 2019 (S3) with three replications. Observations were made on different grafting parameters and on the biochemical aspects of grafting. Among the different methods of grafting, Wedge grafting done in the month of June- July, 2019 gave highest graft survival percentage (61.65) of the grafted plants. Likewise wedge grafting performed during the month of Oct-Nov, 2018 resulted in early bud sprouting, highest graft success percentage and increased number of sprouts.
