Pengelompokan Pohon Induk Cengkeh Terpilih Di Kabupaten Sumedang Berdasarkan Karakter Morfologi / Clustering of Progeny Clove Accessions From Cimanggu Population in Sumedang Based on the Morphologycal Characters

Cimanggu progeny clove has been distributed to almost of centre production, such as in Sumedang. However, their genotypes are still unidentified. Therefore, clustering cloves accession population in Sumedang is necessary. The objectives of this study is to cluster and determine phylogenetic relationship of Cimanggu progeny clove population in Sumedang base on morphological characters. The experiment was conducted in Sumedang (West, Java) from 2013 until 2014, by using 10 selected accessions (healthy, more than 40 years old, productivity is ≥ 20 kg dried flower). Variables were observed include morphological leaf, flower and flower production. To distinguish genotype from each accession was conducted by cluster analyzed, while to identify the variables which were related to the clusters formation, used correspondence analysis. The results indicated, that clove population Sumedang can be classified into three clusters as followed: the first cluster are Syar 43 and 46 accessions, characterized by greenish orange and greenish purple of young leaves tip with flower tube greenish red (GR 180B), the second cluster are Syar 44 and 45 accession, characterized by tip reddish purple young leaves and greenish red (GR181B) flower tubes color, and the third cluster are Syar 47, 49, 50, 51 and 52 accessions, characterized by orange young leaves tips and greenish red (GR180C) flower tubes. This information can be utilized to support releasing Cimanggu clove variety

Tingkat Kesamaan Tanaman Nilam Hasil Fusi Protoplas Berdasarkan Morfologi dan Anatomi Daun

Similarity Level of Patchouli oil from Protoplast Fusion based on Morphology andAnatomy Leaves. Protoplast fusion between Aceh patchouli (Pogostenton cablin Benth)Tapak Tuan 75 clone and java patchouli (Pogostemon heyneanus Benth) Girilaya clone gonegenotypes variation. The aim of this experiment was to examine the similarities ofmorphology and anatomy of leaves. The experiment was inducted at laboratory and greenhouse of the Indonesian Spice and Medicinal Crops Research Institute from February to July2001. The parameters observed were the number of leaves length, leaves width and leafthickness, the number of oil cell, stomata and trachoma index. Analysis cluster was used toanalysis the data with single linkage method and Euclidean distance concept. The resultshowed that the leaves length, width, and thickness have close similarity with Tapak Tuan 75.The similarity level of genotype from protoplast fusion was 62.68 to 83.27, the parent TapakTuan 75 was 61.53 and the parent Girilaya 58.69. The highest numbers of oil cell was showedby clone 9 I1 4 (10.55) and the lowest was clone ( IV 14 (2.93)

Tanggap Beberapa Klon Nilam (Pogostemon Cablin Benth.) Terhadap Nematoda Pelubang Akar (Radopholus Simitis Cobb.)

Response of some patchouli clones (Pogostemon cablin Benth.) to burrowing nematode (Radopholus similis Cobb.)One of the seious poblems on patchouli is infection of plant parasitic nematode. Nine clones of Aceh patchouli (Pogostemon cablin Benth.) namely KJ (oiginated from tissue cultue) Meulaboh-2, Sidikalang, Lhokseumawe-2, Cisaroni . Cirateun, Tapak Tuan. Aceh Merah. Situak-2, and one clone of Java patchouli (P. heyneanus Benth.) namely Giilaya, were tested to infection of buowing nematode (Radopholus similis Cobb.) in the glasshouse of Research Institute for Spice and Medicinal Crops, Bogor fom July to November 1997. Each clone was inoculated with 500 of R. similis. An expeiment have been conducted to know the esponse of some patchouli cultivars against nematode. The expeiment was arranged in a Completely Randomized Design with thee replicates. The esults showed that the infection of R. similis reduced root weight greater than that of shoot weight, the colour of leaf became reddish or dark purple. Based on the development rate of nematode and level of damage, Giilaya appeared to be resistant, whereas Sidikalang, Cisaroni and Situak-2 clones wee slightly susceptible. KJ. Lhokseumawe-2, Cirateun. Tapak Tuan and Aceh Merah clones were susceptible, whereas Meulaboh-2 were highly susceptible against R. similis. Characteistic of Java clone that esistance and Aceh clone that shyhtly susceptible to R. similis may be useful for providing new vaieties with high content of oil and resistant to nematode
