Effect of Understumps Age on the Growth of Budding of Orange Plant (Citrus Sp.)

Abstract

The research was conducted in the Garden of Development of Horticultural Seeds of West Java Province. The purpose of research to know the influence of age of rootstock and budding method to the success of citrus (Citrus sp). Research method using Factorial Randomized Block Design (RBD) with 2 factors. The first factor is the age of the Understump (rootstock) consisting of 5 levels, namely the stem age of 4, 6, 8, 10 and 12 months, while the second factor is the budding method consisting of 2 levels, namely T (T-budding) budding method and the budding (Chip-budding). The results showed that the treatment of budding method and the age of rootstock did not interact in all observation variables. The treatment of budding method and the age of rootstock independently had a very significant effect on the high percentage of shoots, no significant effect on the stem bud diameter and significantly affect the number of leaves. The best treatment on the method of budding is the method of Insert (Chip-Budding), while at the lowest rootstock is the best age of rootstock 6 months.
