The objective of the experiment was to observe the effect of application of paclobutrazol as growth retardant and hidogen sianamida which can act as dormancy break on growth and flowering of Mango cv. Arumanis. Experiment was conducted at IPB Experiment Station, Tajur, Bogor (250 m above sea level), from April to August 1996. Three-year-old of Mango cv. Arumanis trees were used for this experiment. Trees were planted in the field with spacing of 5 m x 5 m. Experiment using Randomized Block Design, consisted of two factors. First factor was dosage of paclobutrazol i.e. 0 ppm as control and 1000 ppm. Second factor was application time of hidrogen sianamida i.e. no treatment (control), 15 days after paclubutrazol application( HSP), 30 HSP and 60 HSP. Each treatment was replicated six times using one tree for each replication. Observation was conducted once a week on the sprouting bud number, shoot length flowering time, cluster number, and cluster size. Paclubutrazol application significantly played a role in off seson flower induction of mango Arumanis, flower bud sprouting occurred on 61-71 days after paclubutrazol treatment. Percentage of flowering on treated trees was 83.3-100%, while no flowering was observed on the kontrol trees. More-over, paclobutrazol application significantly inhibited vegetatif growth through decreasing total bud sprouted and shortening shoot length. Time of hidrogen sianamida application tended to increase total of bud sprouted To generatif growth, time of hidrogen sianamida application tended to increase cluster number and significantly increase cluster length. Application time of hydrogen sianamida 60 HSP showed vegetatif and generatif growth better as compared with other treatments.

The objectives of this experiment were to evaluate the possibility of using quick lime for extraction of mangosteen seed and the effects on its viability; The experiment was done in Seed Science and Technology Laboratory, Greenhouse, Bogor Agriculture University from November 1997 until February 1998. The materials were taken from smallholder plantation in Jasinga, Bogor. The treatments were arranged factorial in a group randomized block design with two factors. The first factor was 6 levels of quick lime concentration (K) : 0 g/l, 10 g/l, 15 g/l, 20 g/l, 25 g/l, 30 g/l and the second factor was 4 levels of soak periods: 0 minute, 10 minutes, 20 minutes, 30 minutes. The experiments had 24 treatments combination with 4 replicates so there were 72 experiment units. The data show that seed extraction using quick lime gave statistically significant different results compared with seed extraction without using quick lime and so the soak periods compared with no soak. Interaction between 20 g/l quick lime concentration and 30 minutes soak period gave the best seed emergence (96 %). 20 g/l quick lime concentration save higher vigour than other concentration as measured from its speed of germination, spontaneous growth, and root length. The soak periods increased seed moisture content 30 minutes soak period resulted higher viability and vigour than other soak periods as measured from its normal seed dry weigh, spontaneous growth, epycotyl length and root length.
