PENGARUH KONSENTRASI IBA DAN METODE SAMBUNG PUCUK TERHADAP KEBERHASILAN PERTUMBUHAN BIBIT TANAMAN KAKAO (Theobroma cacao L.)
Abstract
The effect of IBA concentration and shoot grafting method on the success of cacao seedling growth (Theobroma Cacao L.). (Supervised by Netty S Said and Aminah Muchtar). The research was carried out in the nursery green house of Tarengge Village, Wotu District, East Luwu Regency. The research was carried out in September - October 2020. The objectives of the study were (1) to determine the success rate of the combination of using IBA with various concentrations in the grafting method of the convoluted shoot, pocong and cocoa plant cover. (2) Knowing the concentration of IBA that can affect the success rate of shoot grafting of cocoa plants. (3) Knowing the best shoot grafting method that can increase the success of shoot grafting of cocoa plants. This study used a randomized block design (RAK) with a factorial pattern of 2 factors (1) Provision of IBA Auxin ZPT consisting of 3 levels, namely 0 ppm (Control), 100 ppm, 200 ppm, Factor (2) shoot grafting method consisting of 3 levels namely convolution, pocong and hood. Produced 9 treatment combinations, each combination was repeated 3 times to obtain 27 experimental units. Each treatment combination used 10 plants for a total of 270 plants. The results showed that the combination of (auxin IBA) and shoot grafting did not have a significant effect on all the treatments tested. (auxin IBA) did not have a significant effect on the growth of grafting cocoa plants. The pocong connection method and the mask joint method are methods that have a significant effect on the parameters tested, but from the average results the pocong connection method is the best method
