Abstract

Increased productivity of pepper should be supported by the availability of improved seed. Propagation black pepper in vitro can be used as an alternative to produce large amounts of black pepper cuttings in a relatively short time. One of the factors that determine the success of in vitro culture is the use of plant growth regulators used. Research was conducted in the laboratory tissue culture from March to September 2011. This research consists of two activities, the induction of shoot multiplication and rooting induction. Each aims to analyze the addition of coconut water concentration on shoot multiplication black pepper and determine the effect of the addition of the type and concentration of auxin for induction in vitro rooting of black pepper. Design used were completely randomized design and use advanced testing DMRT. Treatment consisted of induction multiplication coconut water concentration, namely 10, 20, 30, 40, 50%, and as a comparison is BA 0.3 mg/l, and black pepper root induction treatment using several auxin is IBA, IAA and 2.4-D with the concentration of each was 0.1 mg/l, 0.3 mg/l and 0.5 mg/l. The results showed the use of coconut water for shoot multiplication induction treatment at all concentrations stimulate root formation, in addition to the culture that has produced more normal growth and vigor than the treatment of BA 0.3 mg/l. Treatment BA 0.3 mg/l produce shoots leaves more than coconut water treatment at 2.69 and 10.73. The use of IAA 0.1 mg/l for induction were able to induce root 8.26 more as compared to other auxin.
