Orchid is one of the ornamental plant that has a high aesthetic value. Efforts to increase the quality of orchids can be done by genetic improvement through crossing. The first step to success in orchid crossing requires information on morphological characters of the prospective parents. This study aims to determine the similarity of six species of natural Coelogyne spp based on qualitative morphological characters. Morphological characterization of 6 orchids was carried out based on 30 characters including stem, leaf, flower, pseudobulb, and rooting type. Cluster analysis was carried out with the NTSYSpc program version 2.02i with the UPGMA SimQual function method. The results showed that there were morphological diversities among the six Coelogyne spp on the character of the stem, pseudobulb, leaves, flowers and type of roots. Based on the dendrogram on 73% similarity, three major groups were obtained. The first group consisted of Coelogyne pandurata and Coelogyne rumphii, the second group was C. massangeana, C. mayeriana and C asperata, the third group was C. celebensis. Based on the morphological similarity of 87% there are two pairs of parents that have most successful chance to be crossed, C. pandurata with C. rumphii and C. mayeriana with C. asperata.

Anggrek hitam ( Ceologyne Pandurata ) merupakan tanaman khas dan sebagai maskot flora provinsi Kalimantan Timur dengan nama lokal “Kersik Luai”. Penelitian ini mengembangkan sistem pakar anggrek hitam di Kalimantan Timur dilengkapi dengan basis pengetahuan dalam identifikasi hama, gejala dan  jenis penyakit serta karakteristik budidaya anggrek hitam sebagai upaya pelestarian keanekaragaman hayati Kalimantan Timur. Metode penyelesaian masalah yang digunakan adalah Teorema Bayes. Hasil penelitian ini diperoleh 4 (empat) hama yang mengganggu anggrek hitam yaitu siput telanjang, ulat, belalang dan semut, serta diperoleh 4 (empat) penyakit yang menyerang anggrek hitam yaitu penyakit bercak coklat, penyakit layu fusarium, penyakit busuk lunak dan penyakit busuk akar.

Tribulus (Tribulus terrestris L.) is a medicinal plant with considerable implementation such as aphrodisiac and anti-inflammation drugs. This research was conducted to study the effectivity of coconut water and IAA (Indole-3-acetic acid) application on various concentration as the growth regulator for tribulus growth on the in vitro and its effect toward observation variables. The material used were cotyledon from tribulus embryo and MS (Murashige and Skoog) medium. The research method used a Completely Randomized Design with first factor of coconut water concentration of 0 mL L-1, 50 mL L-1, 100 mL L-1, and 150 mL L-1 and IAA concentration of 0 ppm, 0.15 ppm, 0.20 ppm, and 0.25 ppm as the second factor. Observed variables were shoots emergence time, number of shoots, shoot height, number of leaves, roots emergence time, number of roots and regression between observation variables. The result showed that the combination of 150 mL L-1 coconut water and 0.25 ppm IAA gave the highest shoot height, roots emergence time, and number of roots. Coconut water treatment on 150 mL L-1 concentration alone gave the best result on shoots emergence time, number of shoots, and number of leaves, while IAA concentration of 0.25 ppm independently gave the highest number of leaves. Regression analysis result indicate that the number of roots has a positive correlation with shoots height, number of shoots and number of leaves.

The grasspea (Lathyrus sativus L.) is a versatile crop which used as food, feed and fodder, owing in part to its nutritive qualities (Mahler-Slasky and Kislev, 2010), belonging to the family Fabaceae, subfamily Papilionoideae, tribe Vicieae. It is also known as blue sweet pea, chickling vetch, Indian pea, Indian vetch, white vetch, almorta or alverjon (Spain), cicerchia (Italy), guaya (Ethiopia), and khesari in Bangladesh & India (Cruis, 2006). It has immense economic significance and cultivated as major crop especially in developing nations including India, Bangladesh, Pakistan, Nepal, and Ethiopia (Kumar et al., 2011 and Kumar et al., 2013) whereas, grown to a lesser extent in many countries of Europe, the Middle East, Northern Africa, as well as in South America. It is endowed with many Gamma Rays and EMS Induced Chlorophyll Mutations in Grasspea (Lathyrus sativus L.)

Hartati, S., R. B. Arniputri, L. A. Soliah and O. Cahyono, 2017. Effects of organic additives and naphthalene acetid acid (NAA) application on the in vitro growth of Black orchid hybrid (Coelogyne pandurata Lindley). Bulg. J. Agric. Sci., 23 (6): 951–957 Black orchid (Coelogyne pandurata), Bornean native beautiful orchid, which is currently threatened with extinction, was successfully crossed with Coelogyne rumphii. The hybrids will be multiplicated using in vitro propagation technique. To produce plants with good results both quantitatively and qualitatively it is necessary to add the growth regulator substances and organic additive compound into the culture medium. This study aim to get the best medium composition that is able to optimize the growth protocol for the hybrids of Coelogyne pandurata and Coelogyne rumphii. The experiment was arranged in a factorial design based on completely randomized design with two factors and fi ve replications. The fi rst factor was the concentration of Naphthalene Acetic Acid /NAA (0, 1, 3 and 5 ppm). The second factor was the organic additivess (without any organic additives, coconut water was 250 ml L-1, banana 150 g L-1, potato 200 g L-1 and sweet potato 150 g L-1). The results showed that the addition of 3 ppm NAA capable of accelerating time root emergence. The organic materials affect all of parameter signifi cantly. The combination of 3 ppm NAA with organic coconut water can accelerate the emergence of shoots of 9.8 days after planting (DAP), combination of 1 ppm NAA with coconut water can stimulate the multiplication of shoots as many as 6.29 shoots and combination of 3 ppm NAA with sweet potatoes can increase the number of roots as many as 23.5 roots

Morphological characters of natural orchids (species) is an important key for successful breeding program of orchids. This study was aimed to determine the morphological diversity and to study the genetic relationship among natural orchids from Java. The characterization was conducted on 12 orchids collected from Central, East and West Java from April to September 2012. Twenty five characters including stem, leaves, flower, pseudobulb, and root type were evaluated and scored based on Guidance of Orchid Characterization. Cluster analysis was done using the NTSYSpc version 2.02i under UPGMA function of SimQual. The study showed that there was a diversity on morphology of stem, pseudo bulb, leaf, flower and root type. Dendrogram based on genetic similarity at 52% clustered the population into two groups. The first group consisted of Paphiopedilum purpurascens, P. javanicum, P. glaucophylum, Coelogyne flexuosa, C. spesiosa, Dendrobium mutabile. Bulbophyllum blumei and B. biflorum. The second group was Coelogyne tomentosa, C. trinervis, D. crumenatum, and B. flavescens Lindl Keywords: cluster analysis, dendrogram, diversity, morphology
