Effects of IBA and GA3 on Rangpur lime (Citrus limonia Osbeck)

Abstract

The experiment was conducted in a mist chamber to study the effect of IBA and GA3 alone comprising five concentrations each and in combination on rooting and shooting parameters of Rangpur lime cuttings. Among the various treatments used in the experiment it was found that I2 (IBA 1000 PPM) gave the best response in respect of all the parameters studied viz., maximum number of roots/cutting (3.93), girth of the thickest root (1.38 mm), length of the longest root (4.47 cm), percentage of rooting/cutting (45.37), survival percentage of rooted cuttings (60.00) number of leaves/cutting (2.27), number of secondary branches/cutting (1.87) cutting and number of leaves/sec. branch (4.60) and minimum was with control. With the increase in concentration of GA3 it has consistently inhibited adventitious root formation.
