Abstract

Chili pepper is widely used and cultivated by Indonesian people. There are three species of chili pepper, i.e.: Capsicum annuum L., Capsicum frutescens L., and Capsicum violaceum HBK. Capsicum frutescens L. has a higher economic value due to its pungency and carotenoid content. C. frutescens has several cultivars, one of those is Capsicum frutescens cv. Cakra Hijau. This cultivar is resistant against pest and disease and has very high pungency. This special character of chili pepper is born by its secondary metabolic, Capsaicin. Moreover, capsaicin also serves as defense mechanism, antiarthritis, analgesic, and anticancer. This study aimed to isolate Acyltransferase (AT3) gene which encoding Capsaicin Synthase (CS) enzyme. AT3 gene was isolated through PCR using forward primer 5-ATG GCT TTT GCA TTA CCA TCA-3 and reverse primer 5-CCT TCA CAA TTA TTC GCC CA-3. Data were analyzed using DNA Baser, BLAST, and ClustalX. This study has successfully isolated 404 bp fragments of AT3 gene. This fragments located at 1918-1434 bp referred to AT3 gene from Capsicum frutescens cv. Shuanla. Isolation of upstream and downstream fragments of AT3 gene from Capsicum frutescens cv. Cakra Hijau is undergoing.

Abstract

The conservation of Jamuju Dacrycarpus imbricatus (Blume) de Laub. in Java Island has been considered important. One of the the limitation of such program is related to the viability data on the genetic diversity of species target. The aim of study was to determine genetic variation of D. imbricatus in Bromo Tengger Semeru Park, East Java based on trnL (UAA) intron region. DNA sample was collected from several D. imbricatus seedling population in Bromo Tengger Semeru National Park (BTSNP) in East Java. DNA was isolated and amplified using PCR. Genetic variation was estimated using trnL (UAA) intron sequences. This study confirm that D. imbricatus in Bromo Tengger Semeru has low genetic diversity. Based on the phylogenetic tree, D. imbricatus population from Bromo Tengger Semeru Park is closely related to D. imbricatus from Sabah-Malaysia and Hainan-China with 100 % similarity value. These data implies that population and habitat management of D. imbricatus in Bromo Tengger Semeru should be designed to enhance the population survival in the future.

Abstract

Poeciliidae family consists of small live-bearer fishes with sexual dimorphic. This fishes are widely distributed across Indonesian archipelago, but biological studies on this fish are very limited. This research is aimed to identify the species of Peciliidae fishes which lives in Sari Lake Pasuruan based on gonopodium structures and morphometric analysis. A specific characteristic of the Poeciliidae family is its gonopodium structures which is a modification of 3rd, 4th, and 5th rays of the males anal fin. Each species represented 50 samples male and female from each type we found and measured 26 characters (in mm). Cladogram based on morphometric measurements showed that sample 1 and 2 had 100% similarity, sample 3 had 94% similarity with sample 1 and 2. Sample 4 had 54% similarity with sample 1, 2, and 3. Based on gonopodium structures sample 1 and sample 2 included Xiphophorus hellerii Heckel possess large claw on the terminus of ray 5 hook is small crescent-moon shaped on 3rd ray and lacking of gonopodium palp, sample 3 possesses distal platform with 11 retrosse serrae,and membranous hook so we were able to identify the sample 3 as Poecilia mexicana Steindachner, whilst sample 4 was Poecilia reticulata Peter had a long-pointed comb-like spines on ray 3rd and and has a small hook on the tip of 5p ray.

Abstract

Banyu Biru is a natural lake in Sumber Rejo Village, Winongan District, Pasuruan Regency. There are local fishes in the Banyu Biru called sengkaring and tambra. Biological studies on these fishes are not so much known. This study aims to identify the relationship of sengkaring and tambra compared with the related species ( Tor spp.: Cyprinidae) from Indonesia. Morphometric analysis can be used to clustering and understanding the relationship of taxa. Each species represents 17 specimens (Tambra and Sengkaring) and measured 22 characters (in mm) by using digital caliper and the additional characters (21 characters). The canonical, clustering, similarity and distances were used. Based on morphometric measurements, sengkaring and tambra had similarity with the four species found in Indonesia. Commonly, the population of Sengkaring and Tambra was critical; therefore, studies needed to be carried out to support conservation.

Abstract

The purpose of the research is to examine how to increase cross and self-pollination by solving incompatibility of sweet potato mechanism through sucrose giving on stigma and pollen nuclei checking. Sucrose in different concentration is giving to stigma. Stigma is excised and lubricated with sucrose before crossing and the pedicel is lubricated with 2,4D 100 ppm in lanolin. The result shows both varieties have stigma position longer than the anthers do. Papua Solosa has 94.7% anther dehiscence, 70.25% pollen viability, while MSU 03028-10 has 87.3% anther dehiscence and 87.84% pollen viability. Both of these varieties have receptive stigma. Sucrose level in compatible pollination is lower than in incompatible pollination. Sugar in 50 ppm concentrate can increase fruit setting in self-pollination of Papua Solosa variety from 0% to 70%, 0% to 60% in MSU 03028-10, and 10% to 90% in crossing of Papua Solosa>Keywords : Pollen Morphology, Sucrose Giving, Incompatibility of Sweet Potato

Abstract

Blumea balsamifera D.C, Croton tiglium L, Metroxylon sagu Rottb,and Fagraea racemosa Jackwere used as traditional anti-fertilty of Dayak people in Central Kalimantan. These study are to find out the potential plant as anti-fertility on Swiss Webster (SW) mice. Extracts of Blumea balsamifera D.C, Croton tiglium L, Metroxylon sagu Rottb andFagraea racemosa Jack were administered by gavage at the dose level of 0.26 mg/kg body weight (bw) to female of SW mice for 8 days to examined of estrous cycle.To determine of anti-fertility were administered by gavage of 0.26 mg/kg bw of plant extract to female SW mice and mated with normal male of SW mice. Estrous cycle were analyses every day for 9 days and reproduction display were examined at 15 days after fertilization. The result showed, that estrous cycle are inhibited on estrus and metestrus phase for all of extract traditional plant. Reproduction display showed decrease in the number of live fetuses, number of corpus luteum and body weight of the dam mice treated. The decrease in the corpus luteum further and fetuses attributes antifertilty effect of extract to inhibited foliculogenesis. Out of four extracts tested, Blumea balsamifera D.C extract seems to be more potent in anti-fertility activities compared with other extract of traditional plant.
