Air layers prepared during June and July months with 7500 ppm IBA as well as July and August months with 10000 ppm IBA recorded maximum rooting (100%). Layers treated with 10000 ppm IBA during September month layering recorded highest number of adventitious roots. The softwood grafting in Jamun plants carried out on two species of rootstocks (Syzygium cumini and S. operculatum) from June to October. The grafting success was maximum in the month of June in both S. cumini (94%) and S. operculatum (92%) root stock. The cured scion shows 96 per cent of success during month of June in S. cumini and 92 per cent in S. operculatum. Length of sprouts and number of sprouts found maximum in S. cumini during the month of July in cured and uncured scions (0.27 and 0.24 cm respectively). The number of sprouts in S. cumini found maximum in cured scions (3.38) used grafts. The days taken for sprouting was minimum during the month of June in cured and uncured scions (11.50 and 12.14 days, respectively) in S. cumini rootstock used grafts. Significantly minimum number of days taken for scion sprouting in cured (12.28 days) as well as uncured (12.30 days) scion grafted on S. operculatum.ennullVARIETAL PREFERENCE AND BIOLOGY OF MULBERRY LEAF-WEBBER, Diaphania pulverulentalis (HAMPSON)Thesis
