| Abstraksi Narasi | : | Brassinolide is a plant growth regulator (PGR) composed of steroidal compounds, and its finding is relatively new compared with the group of auxin, cytokinin, gibberellin, absisic acid and ethylene. Many studies on biosynthesis, chemical properties and physiological roles of brassinolide in plant growth and development have been reported. At relative low concentrations, brassinolide is ver effective to stimulate plant growth and development. However, the application of brassinolide as an alternative technology to increase crop yield is still controversial. Information about agronomical potency and its problem could lead to better understanding of brassinolide use in crop production system. |

| Abstraksi Narasi | : | Translation termination in Saccharomyces cerevisiae cell does not occur like in prokaryotes sell. Saccharomyces cerevisiae is mediated by two proteins eRF1 and eRF3, coded by SUP45 (SAL4) and SUP35 (SAL3) genes. eRFI protein can not function without eRF3 mediation. Interaction between the two proteins an interaction between eRF1 and ribosom are not completely understood. For studying translation termination mechanism on eukaryotes system, Saccha-romyces cerevisiae is used as a model. For studying function structure of eRF1, sal4 mutans have been constructed through mutagenesis in vivo by using mutagen EMS Biochemical analysis through allosuppressor level of hypersensitive paromomysin mutants of sal4 indicates the existing of abaupt variation among the mutants. This phenomenon indicates the existing of various location of mutations. Biochemical analysis by auxotrophic test is intended to know the influence of mutation toward auxotrophic characteristics of sal4 mutants. To know the location of mutation, it is analysed by molecular genetic: cloningsal4 mutants with allele rescue method. This cloning method is based on the capability of DNA end to recombine homogicly and using repair capability of gapped molecule. |

| Abstraksi Narasi | : | One of the important nutrients for pod development of peanut is calcium. The calcium deficiency could affect the development of gynophore to form pod resulting in unfulfilled pod shell of peanut. Consequently, the objectives of this study were to evaluate the formation of peanut pod as affected by calcium application and to elucidate the role of calcium application on peanut pod formation. This study was conducted in a pot experiment (1/2000 a wagner`s pot) using Tapir and Nakateyutaka peanut varieties. There were two calcium conditions, no CaCo3 application and with CaCO3 application in the fruiting zone (4 g CaCO3). The nutrient content was analyzed by ICP with sample of 0.5 g dry weight that was put into teflon. The result showed that without Ca application in the fruiting zone, the peanut plant produced 23 no. of gynophore with 69% of total gynophore. Yet, Ca^2+ application in the fruiting zone could increase the no. of gynophore up to 28.3 with 89% mature pod of total gynophore. Additionally, under no CaCO3 application, the content of Mg^2+ and Ca^2+ in pod shell decreased 23 and 41%, respectively over CaCO3 application. This indicates that calcium might induce the pod formation which leads to the increase pf pod weight and seed weight. Moreover, it was elucidated that calcium in the fruiting zone has probably important role on the peanut pod formation. |

| Abstraksi Narasi | : | Hikam and Yuliadi (1996) have derived a maize cultivar of synthetic Unila-1 as a progeny of intermated 10 Self-2 lines derived from 10 commercial maize hybrids. The multiplication of class of Foundation Seed was done in the dry season May-August 1999. In the multiplication, the Foundation Seed was grouped into three genotypes: (1) large seed, (2) small seed-one ear, and (3) small seed-two ear. The grouping was referred to the demand of user-farmers that prefer small seed-two ear genotype. |

| Abstraksi Narasi | : | Missing observations in split plot design create many analysis problems. In this article, we consider the problems for a split plot design with missing some observations. The size of the design matrix are considered, to know weather the model with missing data is full rank. |

| Abstraksi Narasi | : | Plant regeneration in vitro is affected by its culture environment. Although many factors can potentially influence shoot-tip cultures, the two most important are the incubation temperature and the light regime. The objective of this research was to elucidate the effect of the incubation temperature on shoot multiplication of strawberry originated from apical meristem. we used MS medium (Murashige and Skoog, 1962) enriched with supplements and 1mM benzil adenin (BA). After being subcultured once, selected healthy shoots were then grown for 8 weeks on the similar medium and incubated at two different temperatures, namely 15 ± 2` Cor 26 ± 2` C with 16-hour light and 8-hour dark of photoperiods. White cool fluorescent lamps at the intensity of 1000 lux were used as a light source. The experiment was arranged in a completely randomized design with 8 to 10 replicates. Each experimental unit consisted of a 250 ml capacity vessel which was filled with 40 ml medium and planted with 3 shoots per vessel. Results showed that shoot fresh weight at 15 ± 2` C was 15% higher at 6 weeks after planting (WAP) and became 27% higher at 8 WAP than those of at of 26 ± 2` C. In general, culture grown at 15 ± 2` C showed better performance (longer shoots, wider leaves, and more rigorous roots) than those of at 26 ± 2` C. It can be concluded that lower incubation temperature stimulated both shoot and root growth of strawberry plantlet in vitro. |
