Abstract:
Dragon fruit is a horticultural plant species originating from America and introduced to Indonesia in 2000. Dragon fruit cultivation continues to be done because it is very profitable and has a great chance to developed. These opportunities must be balanced with the provision of seed. PGRs concentration and seeding system is a factor that must be considered in the nursery because it will affect the growth of seedlings in the field. The research was conducted at dragon fruit plantation Tameran village Bengkalis regency. The time used in this research lasted from August to December 2012. The design used was a Completely Randomized Design (CRD) 4 x 2 factorial with 3 replication. The first factor is the PGRs concentration, which is 0 g/10 ml, 6 g/10 ml, 9 g/10 ml and 12 g/10 ml length cuttings. While the second factor is the seeding system, which is indirect seeding system and direct seeding system. The parameters measured were the time appeared shoot, shoot length, number of shoots, root length, number of roots, root volume, seedling fresh weight gain and dry weight of seedlings. Data were analyzed statistically using analysis of variance (ANOVA) and further tested by further testing (DNMRT) level of 5%. Results shows of the best dragon fruit seedlings growing on a combination between 6g/10 ml PGRs concentration with direct seeding system.
