Keragaman Beberapa Aksesi Temu Hitam (Curcuma Aeruginosa Roxb.) Berdasarkan Karakter Morfologi

Curcuma aeruginosa Roxb. or black turmeric belongs to the family Zingiberaceae is one of the important medicinal plant that is widely distributed in Southeast Asia, including in Indonesia. This plant has been used by the people especially as raw material for medicine and cosmetics industries. However, the development of black turmeric is still constrained by the availability of germplasm collection and improved varieties. The objective of this study was to determine the vegetative morphological characters and phylogenetic relationship among 10 accessions of black turmeric and 3 accessions of genus Curcuma in Indonesia. Data was collected for 15 morphological quantitative characters of black turmeric at the Experimental Garden at Sukamantri IPB based on UPOV and PPVFRA descriptors. The result of principal component analysis has determined three principal components with the proportion of diversity 73.94%. Cluster analysis three clusters accession of black turmeric, namely cluster 1 consisted of accession Cianjur, Malang, Rimbo, and Kendal; cluster 2 consisted of accession Bogor, turmeric (Curcuma longa L.), java turmeric (Curcuma xanthorrhiza Roxb.), Liwa, Natar, white turmeric (Curcuma zedoaria Roscoe.); cluster 3 consisted of accession Cirebon, Kuningan 1, and Kuningan 2

Karakterisasi Morfologi dan Sifat Kuantitatif Gandum (Triticum Aestivum L.) di Dataran Menengah

Indonesia is one of the largest wheat importers. Suitable environmental condition for wheat needs to be studied if wheat is going to be widely cultivated in Indonesia. The adaptability of wheat grown in various climates and altitudes is one of the important aspects. The objective of this experiment was to study the quantitative and morphological character of wheat grown in middle land (540 m asl) in Bogor, West Java. The experiment was arranged in randomized complete block design with three replications. Wheat genotypes used were three national varieties (Nias, Selayar, and Dewata), four new improved varieties (Guri 3 Agritan, Guri 4 Agritan, Guri 5 Agritan, and Guri 6 Unand), and one introduced genotype (SBD). Data were collected for several quantitative variables and seventeen morphological characters based on UPOV descriptor. The result showed that wheat growth was restricted in Bogor. Genotype determined plant height, leaf number, ear length, root length, number of spikelet, harvest time, seed weight, number of tillers, and plant biomass. Based on ear length, grain weight, and plant biomass, Guri 3 Agritan had the highest production than the other genotypes

Uji Cepat Toleransi Tanaman Padi terhadap Cekaman Rendaman pada Fase Vegetatif

The major constraint of rice cultivation in the flood-prone area is the lack of tolerant varieties. A rapid screening method have to be developed under controlled environments, such as a green house, to improve the effectiveness and efficiency of the selection under submergence condition. The aim of this research was to study the correlation beetween selection methods in greenhouse and in the field. This experiment was conducted at a green house of Muara Experimental Station, Bogor in 2011/2012. The experimental designs used were randomized complete design for greenhouse experiment and randomized complete block design for field experiment, with three replicates respectively. There were four sub-experiments in the greenhouse experiment, grouped based on seedling age (10 days and 35 days after seeding) and duration of submergence (10 days and 14 days). Those sub-experiments in the green house were compared with the experiment in the field. The results showed that there was strong correlation between recovery percentage in the green house and percentage recovery in the field. The same correlation indeed happen between recovery percentage in the green house to grain yield. Complete submergence at 10-day-old seedlings in green house could be developed as rapid selection method for submergence tolerant rice.Keywords: aciotic stress, correlation, flooding, Oryza sativ

Induksi dan Proliferasi Embriogenesis Somatik In Vitro pada Lima Genotipe Kedelai

Somatic embryo induction medium was reported to be genotype dependent for soybean. This study was aimed to obtain the optimum medium for embryo somatic induction and proliferation, and to regenerate somatic embryo of five soybean genotypes. Five soybean genotypes (Tanggamus, Anjasmoro, Yellow Biloxi, CG-22-10, and SP-10-4) were used in this study. The research was divided into four steps: (1) embryogenic callus induction of five soybean genotypes, (2) embryogenic callus proliferation of five soybean genotypes, (3) optimation of embryo somatic induction on five soybean genotypes and (4) embryo somatic regeneration of five soybean genotypes. The induction experiment showed that based on number of embryogenic callus, the best somatic embryo-induction medium was 3% sucrose+ NAA 5 mg L-1+2,4-D 5 mg L-1+ Vitamin B5. Embryogenic callus number for each genotype tested was increased on proliferation media of 3% sukrosa + 2,4-D 5 mg L-1 + NAA 5 mg L-1+ Vit B5, and Yellow Biloxi gave the highest number of proliferated somatic embryos compared to other genotypes. Increasing number of globular somatic embryo of all genotypes was obtained from the optimation of somatic embryo induction media being used, and Tanggamus genotype gave the highest number of globular somatic embryo which followed by Yellow Biloxi genotype. Tanggamus and Yellow Biloxi genotypes were also successfully formed the four steps of somatic embryos (globular, heart, torpedo, and cotyledonary stages), but in regeneration medium of MS0 and media MS + sukrosa 10 g L-1 + GA3 2 mg L-1 + BAP 4 mg L-1 + Vit B5 only Tanggamus genotype was regenerated into plantlet

Toleransi Beberapa Genotipe Gandum (Triticum Aestivum L.) terhadap Kekeringan pada Stadia Perkecambahan

Drought is a major abiotic stress impeding wheat production world wide. Selection of potentially drought tolerant genotypes are necessary for wheat improvement. The objective of this study was to test the tolerance level of nine wheat genotypes to drought stress at germination stage. Assesment at germination stage using osmoticum solution is an effective method for selecting tolerant genotypes to drougt stress in a short period of time. The experiment was arranged on a randomized complete block design with two factors and three replications. The first factor was wheat genotype consisted of Nias, Selayar, Dewata, H-20, Munal, SBD, SBR, S-03, and YMH. The second factor was concentration of PEG 6000 consisted of 0, 5, 10, 15, and 20%. Observation variables were germination percentage, shoot length, root length, number of root, number of leaf, seedling fresh weight, and seedling dry weight. Increasing level of PEG concentration inhibited the growth of wheat seedling. Based on the highes R2 value on the regression analysis, relative root length can be used as selection character. Based on RD50 value of relative root length, 15% PEG was determined concentration to select drought tolerant on wheat genotypes. Nias genotype was identified as tolerant genotype, while SBD, S-03, YMH, and Munal were identified as drought sensitive genotypes
