Abstract

Exploration, Identification and Study of Flowering and Fertilization Phenology of Salak Cultivars in Bebandem District, Karangasem, Bali. Salak in Bali is one of the most popular fruit plants and widely developed in Bali. This study aimed to identify the types of zalacca cultivars in Karangasem Regency, compiled the profile of plant genetic resources concerning morphological and agronomic characters, photographs of genetic resources as well as the flowering and fruiting phenology of salak cultivars. The research was conducted in Bebandem District, Karangasem Regency, from December 2019 - April 2020. The research was consisted of 5 (five) stages, i.e.: (1) collected secondary data, (2) collected primary data, (3) identification the morphology and agronomy characters, (4) phenology studies of flowering and fertilization and (5) tabulation and data analysis. The results showed that there were 12 types of salak cultivars in Bebandem District, with different phenology of flowering and fertilization for each cultivar. Based on the agronomic characters, the most superior salak cultivated include salak gula pasir (Salacca zalacca var Gula Pasir), salak gondok (Salacca zalacca var Gondok) and salak nangka (Salacca zalacca var Nangka).

Abstract

Vanilla (Vanilla planifolia Andrews) is a plants that has fruit with high economic value. The purpose of this study was to determine the concentration of Rootone F, types of growing media, and their combination to increase the success of one segment propagation of vanilla. This research was conducted from December 2020 to March 2021, located in Melinggih Kelod Village, Payangan, Gianyar. This study used a factorial randomized block design (RBD). Factor I: concentration of Rootone F which consists of concentrations 0 ppm (R0), 750 ppm (R1), 1.500 ppm (R2), and 2.250 ppm (R3), factor II: type of planting medium consisting of soil (T), soil + husk charcoal (TA), soil + cocopeat (TC), and soil + compost (TK) which was repeated 3 times. The concentration of Rootone F 2.250 ppm caused the highest total dry weight (4,30 g) or 49,31% higher than the 0 ppm treatment. The type of planting media soil + compost media caused the highest total dry weight (4,06 g) or 28,07% higher than the soil treatment. The combination of 2.250 ppm Rootone F with soil media + compos caused the highest total fresh weight of 85,07 g or 95,20% higher than 0 ppm Rootone F with soil media.
