Abstract

Research on the effect of soil moisture on agronomic characters, yield and nicotine content of Temanggung tobacco has been conducted in the Research Institute for Tobacco and Fibre Crops at Malang, East Java from March to October 2010. The treatment has been arranged in a Splitplot design with 3 replications. The experimental plot consisted of three types of soil: Complex Eutrudepts-Hapludalfs, Vitraquands, and Complex Dystrudepts-Hapludalfs. The subplot comprised 5 levels of soil moisturation: 60, 70, 80, 90, and 100% of field capacities. The results showed that the dry slice yield, content of nicotine, and agronomic characters of the Temanggung tobacco were affected by the result of interaction between soil moisture and type. The decreasing of soil moisture up to 40% from field capacity in the Complex Eutrudepts- Hapludalfs had decreased dry slice yield, nicotine content, plant height, root length, dry weight of plant, shoots, roots, stems, leaves, flowers, and suckers accounted for 54.3, 19.3, 33.7, 17.1, 74.1, 71.4, 82.3, 80.1, 54.3, 60.5 and 86.5% respectively, in the Vitraquands 72.7,20.2, 37.0, 13.2, 79.8, 78.5, 84.3, 80.7, 72.7, 63.3 and 87.8% respectively, and in the Complex Dystrudepts-Hapludalfs 74.2, 23.0, 39.6, 15.7, 79.3, 78.0, 83.6, 80.3, 74.2, 79.1 and 80.6% respectively.

Abstract

Bamboo is one of the important and favorite plants in the villages, however the management of this plant is less interest either from the people or even the government. Because of that there are many bamboo garden has been turned into housing or industrial area, although some people understand that bamboo can be used to prevent soil erosion as well as water conservation. In Central Java, bamboo is mainly used to make furniture, whereas the bamboo handicrafts is only made by the local people for daily uses.The uses of bamboo for handicraft is mainly occurred in Yogyakarta Province, although the bamboo material for this purposes is imported from Central Java. Because of that a study on the bamboo stand in Central Java Province is very important to support the furniture industry which is found also in this neighbouring city. Based on a study done at the Promasan Village, Salatiga, it is found that the bamboo stand occurred in the plot (50 m x 50 m, 5 plots) was 332.96 clum/ha on 2003, whereas the bamboo stands on 2004 decreased till 331.2 clump/ha. The number of clump might decrease due to over harvesting, so many clump was died. The same phenomena was also occurred at the bamboo potency on 2004 which was decreasing compare to 2003 data. The bamboo potency/clump might be increased, but the total production of bamboo culm/ha/year was decreasing sharply compare to the bamboo condition on 2003. This situation can be seen also from the regeneration of bamboo which was decreasing compare the data on 2003 to 2004. The species found in this village was bambu tali (Gigantochloa apus), which was dominated at this village. This potency of this bamboo stands is very high, because the local people used this bamboo for daily use and it used more than other species.However,Gigantochloa atter has also a demand for the bamboo furniture, because of that the potency of this species is also high.Then Dendrocalamus asper which also been used for bamboo furniture. The potency of Bambusa vulgaris is very low in this village, because this species was rarely used.

Abstract

T. DJARWANINGSIH. 1986. The genus Capsicum L. (Solanaceae) in Indonesia. Berita Biologi 3(5) : 225 - 228. Most of the twelve recognized species of the Central and South American genus Capsicum L. (cabai, lombok) are known to be widely distributed from lowland to mountains. The recent introduction of new Capsicum species into Indonesia has opened an opportunity to confirm the identity and to compile a list of the species occuring in this country. Therefore the diagnostic value of flower and fruit numbers,which are commonly used in classifiying this genus, are analyzed to find out their applicability in the tropic. This study was based on all herbarium specimens preserved in Herbarium Bogoriense, and those fresh Capsicum which are cultivated in Bogor and Cibodas Botanical Gardens as well assgmen other locations. The results of this study indicated that corolla and seed colours, flower or fruit position and pubecity are taxonomic characters which can be used in the tropics. Nowadays the genus Capsicum in Indonesia is represented by five species i.e. C. annuum L., C. frutescens L., C. violaceum H.B.K., C. chinense Jacq., and C. pubescens R.&P.

Abstract

Gewang (Corypha utan Lamarck), a wild or semi-wild palm species distribute widely in Nusa Tenggara savanna with great potential(as building materials, drink and food), as traditionally have been exploited and utilized by local villagers for ages.To increase her potential should be promoted by plant domestication applied as on farm model such as agroforestry and social forestry. Seedlings availability is one of the basic need when comes to plant domestication. The only possibility of propagation in gewang is by generative phase (seeds). On the other hand, gewang seeds are known as orthodox, with low percentage of germination. This study shows that mature gewang seeds dropped under the mother trees are highly protected by tight tissues of endocarp and endosperm. Although the mature seeds in the nature seems ready to germinate, however there should be a dimensional balance (chemical, physical and physiological) or synchronization among components (endocarp/testa, endosperm and embryo) as a driving force to promote germination.In nature, the attainment of this synchronization/ dimensional balance of gewang seeds, are driven by external (both biotic and abiotic) factors as well such as fungi and climatic fluctuations. While artificial treatments like scarification, soaking, heating and acid are to accelerate the dimensional balance. Low embryo content per 100 seeds also responsible for low seed germination. It is suggested that low embryo content may be due to interactions among factors like low fertility of pollen grains, time incompatibility between gynoecium (stigma) and androecium (pollen grains) during pollen shed process and ineffectiveness of pollination due to great number of flowers.

Abstract

Identification of Gouramy is required to obtain phenotype characteristics information of the population for sustainable aquaculture  practices. In this study phenotype diversity of giant gouramy strain bastar and bluesafir was analyzed based on  meristic and morphometric measurement. Sample, are taken from 30 individuals of each population. The result showed that there were differences in colour patterns between the two populations, bastar population had yellowish brown body and red fins, whilst bluesafir population had brown blackish brown body and fins. The canonical function of truss morphometric analysis on 21 characteristics showed the measurement distribution of that both populations were in different quadrants. The intrapopulation similarity index showed that population of strain bluesafir had higher genetic similarity (80%) with interpopulation similarity index of 23.3%, while the intrapopulation similarity index of strain bastar was 76.7%.

Abstract

This research aimed to obtain information on the variability of crossbred resulted from three stocks of red claw (Cherax quadricarinatus von Martens). This research was performed at Research and Develepment Institute for Freshwater Aquaculture.Nine population consists of tree true breed and six reciprocal breed were resulted from the crossbreeding between the three stocks from Jakarta, Bali and Sukabumi.Results showed that the crossbred between Bali female parent and Jakarta male parent had the highest number of larvae / kg weight of female parent compared to the other crossbred. Between the female parent category, the Bali female parent showed the highest number of the larvae yielded, and between the male parent category, the Sukabumi male parent did. There was no significant different between the crossbred on the respon of growth performance. The highest heterosis on the number of larvae was achieved by the crossbred between Bali and Jakarta (25.8%) while the crossbred between Bali and Sukabumi performed the negative heterosis (-17.6%).Based on the calculation of the number larvae per kilogram weight of the parent, the highest heterosis was achieved by the crossbred Bali-Sukabumi (98.4%).The heterosis on the final weight and length showed the poor result, while on the respon of the specific growth rate showed negative result.It can be concluded that this undertaken hybridization did not provided the significant positive heterosis effect except for the number of larva per unit weight of parent.
