Abstract

An experiment on in vitro root induction of Tetrastigma rafflesiae Miq. on Murashige-Skoog (MS) medium suplemented with several concentrations of Indole-3-Butyric Acid (IBA) had been done from February to April 2013. The aims of this experiment was to determine physiological responses of T. rafflesiae’s shoot to the IBA on half strength media of MS for root induction stages. The experiment used a completely randomized design in seven treatments and four replications. The treatment was the addition of IBA in several concentration (i.e. 0.0; 0.5; 1.0; 1.5; 2.0; 2.5 and 3.0 mg/l). The results showed 0.5 mg/l suplemented IBA was more effective and efficient in root induction of shoot then other concentrations. It influenced the average number of roots (12.5 root/plantlet), the average length of root (4.98 cm) and the morphological of plantlets. The result indicated that plantlet of T. rafflesiae generated in in vitro have a higher possibility of artificial culture and give light for future conservation of Rafflesia.Keywords : Tetrastigma rafflesiae Miq., root induction, Indole-3-Butyric-acid.

This experiment used randomised complete design in 11 treatments and three replications. The treatment were the addition of BAP (1.0-5.0 mg/l) and its combination with NAA (0.1 mg/l) on MS medium. The results showed that nodus successfully producing shoot and callus. The addition of BAP was more effective than its combination with NAA in shoot multiplication. MS medium with addition of 2.0-4.0 mg / l BAP showed a better media for shoot multiplication (2.3-2.7 shoot each explant). Generally, MS media with combination of BAP and NAA produced a higher shoot although it did not significantly differed with BAP treatments. The result indicated that addition of BAP in in vitro medias have a high possibility of success for shoot multiplications in Rafflesia’s host plant conservation.

Abstract

The aim of this research was to study the responses of Andalas somaclone explant and to determine the best concentration of thidiazuron (TDZ) for shoot multiplication. It used completely randomized design (CRD) in factorial with two experimental factors and three replications. The first factor was source of nodal explant; explant without colchicine treatment and explant with colchicine treatment (0,1% for 72 hours immersion time). The second factor was five levels of TDZ which were 0; 0.125; 0.250; 0.375 and 0.500 mg/l. The results showed that all treatment gave life percentage of explant 100%. The best timing of shoot formation were 5.33 day after cultured (dac) from explant without colchicine treatment and 5 dac from explant with colchicine treatment. TDZ 0,500 mg/l from explant without colchicine treatment showed the highest number of shoots (12.67) while TDZ 0.375 mg/l for explant with cholchine treatment (10.67). The highest length of shoot were showed in TDZ 0.125 mg/L from explant without colchicine treatment (32.33 mm) and explant with colchicine treatment (38.33 mm). The length of shoot decreased along increasing of TDZ concentration, while the number of shoot increased along increasing of TDZ concentration.Keywords: Morus macroura Miq. var. macroura, multiplication, thidiazuron, explant, in vitro
