Abstract

Cacao is one of important plantation crops grouped in the Sterculiaceae family. Sulawesi is the main area of cacao production and has a number of superior clones, such as Sulawesi 1 and Sulawesi 2. Based on data in 2012/2014 cacao production to consumption reached 174,000 tons, while in 2013/2014 was projected a deficit of 115,000 tonnes. Nonetheless, cacao agribusiness in Indonesia is still facing complex problems, among others gardener productivity is still low due to borer attacks cacao, the quality of products and the number is still low and still not optimal development of cacao products and providing superior amount of cacao seedlings. The primary problem of cacao production recently is low productivity. The main cause of low cacao productivity in Central Sulawesi is the use of inferior clones. To enhance cacao productivity, it is crucial to use cacao clones having high genetic potential via tissue culture or micropropagation techniques. The aim of this experiment was to assess the effect of different concentrations of 2,4-D and coconut water on the growth of cacao callus via in vitro culture. This experiment used Completely Randomozed Block Design in factorial patteren with treatments tested namely 2,4-D and coconut water concentrations. The concentrations of 2,4-D tested including 1 ppm, 2 ppm and 3 ppm, whilst coconut water concentrations tested consisting of 10%, 15% and 20%, and therefore there were 3 x 3 = 9 treatment combinations. Each treatment utilized 4 replications; and each unit combination used 5 explants (staminodia). Results of this experiment indicated that the addition of 3 ppm 2,4-D and 10% coconut water had a highly significant effect on the callus color 4 weeks after culture. The addition of 3 ppm 2,4-D in culture media showed a significant effect on callus color 4 weeks after culture, but had an insignificant effect on the callus formation, callus color 8 weeks after culture an callus texture. Supplementation of 20% coconut water had a significant effect on callus texture 8 weeks after culture, whilst the addition of 10% coconut water showed a significant effect on callus color 4 weeks after culture.

Abstract

The most crucial step during the development of tissue culture is the method of explant sterilization. Especially, explants is sourced directly from fields that were more susceptible to microbial contaminations. This study aimed to obtain sterilization technique from several sterilant for reduced contamination and support growth of shoots grape in vitro. This research was conducted at the Laboratory of Plant Biotechnology, Faculty of Agriculture, University of Tadulako, during January to April 2018. The study used a factorial completely randomized design, one factor was tested i.e S1 = Taft 8,3 g/L (0,1% carbendazim), S2 = taft 25 g/L (0,3% carbendazim), S3 = taft 41,67 g/L (0,5% carbendazim), S4 = Taft 8,3 g/L (0,1% carbendazim) + HgCl2 0,1%, S5 = Taft 25 gr/L (0,3% carbendazim) + HgCl2 0,1% dan S6 = 41,67 gr/L (0,5% carbendazim) + HgCl2 0,1 %. There were six treatment and each treatment was replicated three times to obtain 18 experimental units. Each experimental unit using two explant. Data were analyzed using analysis of variance and followed by Honestly Significant Difference test at level of 5% if the treatment effects were significant. The results showed sterilization technique using taft 41,67 gram / L containing 0.5% carbendazim for 30 minutes, followed by 70% alcohol for 30 seconds and HgCl2 0,1% for 10 minutes gave free contamination for explant.whereas, Taft 8.3 g / L (Carb 0.1%) for 30 min, followed by 70% alcohol for 30 seconds is a sterilization technique that does not inhibit explant growth as indicated from the most callus formation.
