Abstract

Pomegranate regarded as fruit of paradise which commercially propagated by hard wood stem cuttings but the method is not yet standardized as the plant raised are weaker due to shorter and lesser number of roots resulting in poor survival. Therefore, an experiment was planned at the Garden of Department of Fruit Science, Chandra Shekhar Azad University of Agriculture and Technology Kanpur (U.P.). The experiment conducted in the two consecutive years of 2019-20 and 2020-21. Four levels each of NAA and IBA i.e. 3000, 4000, 5000, and 6000 ppm with and without GA3 2000 ppm along with a control (Water Spray) were taken. Thus there were 18 treatments all tried in Randomized Block Design replicating thrice pooled analysis of the data recorded that treatment IBA 4000 ppm + GA3 2000 ppm significantly maximized percentage of rooted cuttings (82.83%), number of primary roots per cutting (44.37), length of longest root (16.37cm), diameter of root (2.49 mm), fresh weight of roots (385.33 mg) and dr

Keywords

IBA, NAA, GA3 root initiation, Primary roots and Dry and Fresh weight of roots.

Conclusion

In view of the above achievement it is concluded that the treatment of IBA 4000 ppm + GA3 2000 ppm proved most effective enhancing rooting of cuttings, number of primary roots, length of longest root, diameter of root and fresh and dry weight of roots. Further investigation should be planned with the present treatments to observe the health and survival of cuttings as these parameters and closely related with the rooting performance.
