Abstract:
The present investigation was undertaken to know the pre-bearing performance of various rootstocks in sweet orange cv. Sathgudi. In this study, different rootstocks namely Rough lemon, Rangpur lime, Alemow NRCC-1, NRCC- 2, NRCC -3, NRCC-4, NRCC-5 and NRCC-6 were budded with scion of Sweet orange cv. Sathgudi. The results revealed that scion budded on NRCC-3 took minimum (17.66 days) for first bud sprouting and (26.22 days) for 50% sprouting contrarily the NRCC-1 root stock took a maximum (22.44 days) for first bud sprouting and (31.44 days) for 50% sprouting. The scion attributes like length of the scion, diameter of the scion, sturdiness quotient, number of leaves, number of nodes, length of internodes, relative water content (RWC), and girth of the rootstock were found to be maximum in the scion budded on NRCC-3 rootstock and the minimum were recorded in scion budded on NRCC-1. The total chlorophyll content (1.11 mg/g) including chlorophyll -a (0.85 mg/g) and chlorophyll -b (0.37mg/g) was found to be maximum in scion budded on Rough lemon rootstock while the lowest was recorded in NRCC-1.
