Judul: Induksi Pembungaan Jeruk Siem Kintamani dengan Paclobutrazol dan Zat Pemecah Dormansi BAP
Abstrak: Siem Kintamani is one of superior citrus commodities in Bali. The problem that faced by Siem Kintamani farmer’s is production of fruit is not distributed throughout a year. The purposes of this research was to study the effectiveness of paclobutrazol and dormancy-breaking substance BAP to induce flowering of Siem Kintamani (Citrus reticulata Blanco). The research was conducted at Siem Kintamani farmer’s in Mangguh Village, Bangli Regency, Bali in October 2014 to March 2015. The research was arranged as factorial randomized block design with 2 factors and 4 replications. The first factor is paclobutrazol aplication consists of 4 levels; 0, 0.5, 1.0, and 1.5 g/plant. Second factor is BAP aplication consists of 3 levels; 0, 100, and 200 ppm/plant. The result showed that the paclobutrazol effected to decrease the total of the shoots produced, shoot length, and increase the total of flowers. Paclobutrazol 0.5 g/plant increase total flowers production from Siem Kintamani plant. BAP 200 ppm increase the total shoots and not influence the flowering of Siem Kintamani plant. Combination treatment of paclobutrazol 1.5 g/plant and BAP 200 ppm/plant can increase the total of shoots production.

Judul: The Off-Season Flowering Induction of „Keprok‟ Citrus Tree (Citrus reticulata).
Abstrak: The purposes of this study were to study (1) the effectiveness of flowering induction treatments (Prohexadion-Ca, Paclobutrazol, and strangulation) toward Keprok, (2) the effectiveness of dormancy-breaking substance treatments (etephon, BAP, and KNO3) on the flowering of Keprok, and (3) the interaction effect between flowering induction treatment and dormancy-breaking substances on the flowering of Keprok. This research was conducted at orange farm in Tangkil, Caringin Bogor Sub-district which lasted from November 2012 until July 2013. This experiment used a separated block design (Split Block Design) which consisted of two factors. The first factor is the flowering induction consists of four levels i.e. control, Prohexadion-Ca, Paclobutrazol, and strangulation. Whereas, the second factor was the provision of dormancy -breaking substances consisted of four levels i.e. control, etephon, BAP and KNO3. From treatment combination, there were 16 trial units and 4 replications. As a result 64 plants were used. Young citrus tres used in this research have similarity of age (5 years). Flowering induction treatment, namely, Prohexadion-Ca, was applied to the leaves twice. The first application after flush getting mature and the second was one week after the first application was done, with a concentration of 500 ppm/ plant in a liter of water. Paclobutrazol was applied to the soil once after flush getting mature with of 2 g/plant in a liter of water. Strangulation was done by a wire twist with diameter of 2 mm. The wire was twisted at a height of 30 cm. The wire twist was made after trubus getting mature. Dormancy-breaking substance treatment was applied 45 (HSA) flowering induction. Each dormancy-breaking substance was in liter of water added with 200 ppm ethepon, 200 ppm BAP, and 40 g KNO3 for each tree. The results showed that the flowering induction treatments (Prohexadion-Ca, Paclobutrazol, strangulation) gives the significant effect to accelerate of flowering and increase the number of flower and fruit on keprok tree. Prohexadion-Ca treatment has ability to accelerate of flowering time better than Paclobutrazol. Paclobutrazol, Prohexadion-Ca and strangulation gives the effects to increase the number of fruit due to these treatments are able to increase the C/N rasio in the leaves tissue. Dormantion breaking treatments doesn‟t gives the significant effect to accelerate of flowering time and increase the number of flower and fruit.
