But, by conventional methods, induction of rooting is difficult. In this investigation, an attempt was made to induce de no rooting in guava varieties like Arka Kiran and Arka Mridula and in jackfruit varieties like Gumless and Tubugere-1 through macropropagation methods. In these fruit crops, root induction was done using four different PGPR strains like AR1, AR2, AR3 and AR1000 and different combinations PGPR and hormone treatments was used. Out of the four PGPR strains PGPR strain AR 1000 was found to be better in inducing roots. Out of different hormones used, IBA and NAA were found to be better in inducing roots and AR 1000 in combination with IBA also gave good results in both guava and jackfruit. Shoot tip micrografting was done onto already established rootstocks. Softwood grafting method was also undertaken in guava and jackfruit varieties which gave us very good results. We obtained adventitious rooting in all the selected treatments.EnglishDE NOVO INDUCTION OF ROOTING IN GUAVA AND JACKFRUIT THROUGH MACROPROPAGATION TECHNIQUESThesis
