Applying of length shoots to Determine the Success of Grafting to Effort Supplying of Citrus Plant Seedling

Abstract

Increasing population, yield and quality of citrus fruit can be done through the provision of seedling by grafting method. Grafting is an activity to combine two or more superior properties in one plant. This study aims to determine the effect of entres length on the results of grafting of citrus plants in an effort to provide seeds. This research was carried out using planting media in pots (polybags) as a place to plant seeds. The study was conducted in Belancan village, Kintamani Subdistrict, Bangli Regency with altitude of 500 meters above sea level started from June to September 2018. This study used a Randomized Block Design with 2 factors arranged factorially. The first factor tested was the treatment of entres length, namely: E1 = 1cm, E2 = 2cm, E3 = 3 cm, E4 = 4cm and E5 = 5 cm, while the second factor that was tested were the varieties of citrus plants consisting of JB = pomelo and JS = tangerines. So that, there were 10 combinations of treatments with 3 replications. The variables observed were: the start of shoots, length of shoots, leaf number of shoots, wet shoot weight and shoot dry weight. The results showed that there was no interaction factor significant effect on most variables, excepted for the variable wet weight of shoots, and dry weight of shoots. The best seed yield was obtained at 5 cm enteres length treatment on pomelo varieties, namely the start of shoots on 12,93 days after paste, shoot length of 43.33 cm, number of shoots were 22,00 strands, wet weight of shoots of 56,97 g, and dry weight shoot of 18.20 g.
