The effect of calcium hypochlorite on the viability of cocoa seed
An experiment to study the role of calcium hypochlorite as an aseptic agent of cocoa seeds to preserve its viability had been conducted at the Laboratory of Seed Technology of the Indonesian Coffee and Cococa Research Institute (ICCRI). During the storage PEG-6000 was also used to inhibit seed germination. Seeds collected from GC 7 clone were used in this study. The experiment consisted of two factors. The first factor was the concentration of calcium hypochlorite i.e. 0, 5, 10, and 15 percent. The second one was the concentration of PEG-6000 i.e. 0, 10, 20, 30 and 40 percent. The treatment combinations were arranged on Randomized Complete Block Design with three replications. The results showed that calcium hypochlorite had a significant effect to reduce the amount of infected seeds and to increase the rate of seed germination after storing. Percentage of seed germination and viability were not significantly affected by the treatment of calcium hypochlorite. By using 15 percent calcium hypochlorite the infected seed was as low as 26.67 percent so the seed viability can be kept high (85.33 percent) after 6 weeds storage. The percentage of infected seeds was significantly decreased by the treatment of PEG-6000, however, the other parameters were not significantly affected by the treatment.
