Effect of grafting on success and survivability of jamun (Syzygium cumini Skeels.) varieties

Abstract

Jamun (Syzygium cumini Skeels) is a vital fruit crop for arid regions. An investigation was conducted to assess the propagation success of four jamun varieties (CISH-42, CISH-37, Konkan Bahadoli and Goma Priyanka) in the south western region of Punjab. Data were collected on grafting success, graft survival, sprout initiation, number of sprouts and leaves per graft, graft height, and chlorophyll index. The results revealed that the variety Konkan Bahadoli recorded highest graft success (83.7%, 82.8%) and survival rates (76.6%, 73.9%) during both the years, followed by Goma Priyanka. The var. Konkan Bahadoli recorded earliest sprouting (16.6 days, 15.3 days, respectively in both years) and superior growth parameters, including the number of sprouts and leaves, graft height, and chlorophyll index. Overall, the var. Konkan Bahadoli responded best to grafting performed in March under south-western region of Punjab.
