Abstract

This study aims to examine the effectiveness of gibberellins in breaking dormancy to produce high viability snakefruit (Salacca snakefruit Geartner) seeds. The materials used are snakefruit seeds from Tamareja Village, Donggala Regency, sterile sand media, aquades, and GA3 solution. This research was arranged using a completely randomized design (CRD) with one factor, namely the provision of gibberellin, consisting of five levels of concentration, namely P0 = control (without treatment), P1 = 30 ppm and P2 = 40 ppm P3 = 50 ppm P4 = 60 ppm. each treatment was repeated five times so that there were 25 experimental units. Each experimental unit used 20 seeds. Observation data were analyzed using analysis of variance (ANOVA), followed by Tukey' HSD test if the treatment tested showed a significant effect. The results showed that gibberellin administration effectively broke snakefruit seeds' dormancy and produced seeds with high viability. The higher the gibberellins' concentration would increase germination speed plumule length, radicle length, and faster embryo axis emergence. Gibberellin 60 ppm resulted in germination power 98%, germination rate 20.97 days, plumule length 5.52 cm, radicle length 5.15 cm, and embryo axis emergence 9.2 days.

Abstract

Indonesia's mangosteen exports to several Asian countries, Europe, and the Middle East have increased yearly, especially during the Covid19 pandemic. However, efforts to improve domestic mangosteen cultivation technology are inadequate. The research materials used include 45 mangosteen trees accessed by Donggala and Sigi already producing (age + 20 years) and Urea, TSP, and KCL fertilizer. The tools used are meters, plastic labels, calipers, digital scales, Smartphones, and GPS Garmin 64 Sc. Using a RandomIzed Group Design (RAK), one factor, namely fertilization, consists of three levels of treatment in each District. The observation results were analyzed using ANOVA, and if there was a significant influence, it was continued with the BNJ analysis. The results showed that fertilization treatment using BALITBU TROPIKA Solok and analysis results from the Soil Science Laboratory Unit of the Agriculture Faculty University of Tadulako increased plant height and triangular area stamina by 100 to 300 percent compared to without fertilization. There was an increase in plant height and triangular stamina area by 100 to 300 percent compared to without fertilization. There was an increase in plant height and triangular area stamina by 100 to 300 percent compared to without fertilization. There was an increase in production of fruit height from 155 to 394 percent, fruit/seed locul number from 101 to 106 percent, fruit production per tree from 175 to 178 percent, and fruit diameter from 119 to 137 percent.
