“…The results of this isolation adds the data of isolation result of the initial survey conducted by Agustini et al (2009) in the campus of Faculty of Mathematics and Natural Sciences, Cenderawasih University, located in the buffer zone of CAPC. In her research, she discovered two species of orchid-mycorrhiza, namely Rhizoctonia sp.…”

“…In nature, for the germination and early growth of orchid seed and its development, it needs an association of orchid roots and mycorrhizal fungi (orchid-mycorrhiza) (Warcup 1981;Cameron et al 2006;Suarez et al 2006;Agustini et al 2009). This is because orchid seeds are very small, smooth and soft and have no cotyledon which is a food reserve in the early growth of seeds (Sarwono 2002;Agustini and Kirenius 2002).…”

“…The hyphae of mycorrhizal fungi penetrate to the cell walls of roots and then will be developed in the root cortex as dense coiled called peloton. Mycorrhizal hyphae are very delicate; therefore they will absorb water and certain minerals (Suarez et al 2006;Agustini et al 2009). …”

Sufaati S, Agustini V, Suharno. 2012. Isolation and phylogenetic relationship of orchid-mycorrhiza from Spathoglottis plicata of Papua using mitochondrial ribosomal large subunit (mt-Ls) DNA. Biodiversitas 13: 59-64. All terrestrial mycorrhiza have mutual symbiotic with mycorrhizal fungi in order to gain nutrient from surrounding environment. This study was done to isolate and to identify mycorrhiza orchid that associates with Spathoglottis plicata and were collected from Cagar Alam Pegunungan Cycloops (CAPC), Jayapura. Isolation of mycorrhizal orchid came after the modified method of Manoch and Lohsomboon (1992). The result showed that based on the morphological characteristic, there were presumably 14 isolations. However, only 2 isolations have been known, namely Rhizoctonia sp. and Tulasnella sp., while the rest were not identified yet. Among them, the DNA of the 11 isolations were able to be extracted for further analysis. The constructed phylogenetic tree performed that those species could be grouped into 4 major clusters. Two species, Rhizoctonia sp. and Tulasnella sp. were in different clusters.

Tree species can be considered as hosts for many epiphytes and the orchids, as epiphytes, display a biased distribution among hosts. It is possible that the barks of these hosts have some chemical and physical characteristics that influence the seed germination of orchids. The dependence on symbiotic fungi for seed germination is also a crucial factor for orchid distribution. Dendrobium aphyllum is an orchid species with restricted distribution in the sub-montane region of Sri Lanka. The aims of this study were (1) to determine the host tree specificity of the epiphytic D. aphyllum using physical and chemical bark characteristics of the host, (2) to isolate and identify the symbiotic fungi in D. aphyllum roots and (3) to determine the effect of tree bark extracts on symbiotic seed germination of D. aphyllum. Methanol, dichloromethane, hexane and water were used to extract the chemical compounds in tree barks. Aqueous and organic bark extracts of non host species (Erythrina sp., Erythrina berteroana, Eurya accuminata, Semecarpus marginata, Symplocaceae cochinchinensis) inhibited the seed germination of D. aphyllum. However, the effect of host tree species (Eurya ceylanica, Actinodaphne stenophylla, Eurya sp., Antidesma zeylanicum, Citrus maxima, Semecarpus nigra-viridis and two Syzygium spp.) on seed germination fluctuated with the concentration of host bark extracts. The physical characteristics of bark such as texture, peeling behaviour and thickness showed a positive correlation with the host tree specificity of D. aphyllum. Symbiotic fungus Rhizoctonia sp. was isolated as the associate in D. aphyllum roots.
