Minireview Article the Current Research Status of Endangered
Minireview Article The Current Research Status of Endangered Rhynchostylis retusa (L.) Blume: A Review ABSTRACT Orchids bear the crown of highly evolved ornamental floral specialization in the plant kingdom, but have poor medicinal background. Further, Rhynchostylis retusa (L.) Blume is much less studied plant species among Orchidaceae due to its overexploitation in the wild. This epiphytic herb belongs to the tropical areas and kept under endangered category by CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) that points out its abated natural population. In this sense, the aim is to document the past and present researches upon R. retusa highlighting the traditional and remedial uses, and to ignite the conservation awareness among the people. Keywords: Conservation, medicines, mythology, patents, taxonomy, tissue culture. 1. INTRODUCTION Orchidaceae (monocotyledons) are one of the largest families of the plant world extending from tropics to alpines along with a boon of astonishing beauty in their flowers [1]. Orchids are the richest among angiosperms with diverse species number (approximately >25,000) having epiphytes (more abundant, 73 %), lithophytes and ground plants [2,3]. Fossil records of orchids date back to 100 million years ago [4]. Actually the term ‘orchid’ coming from ‘orchis’ (Greek word) meaning testicle was given by Theophrastus (372-286 B.C.), who reported the use of orchid roots as aphrodiasic. Despite of huge family size, orchids are largely exploited and traded for their ornamental flower diversity but less attention is paid towards their remedial properties. According to Reinikka, the first evidence of the use of orchids as medicines comes from Shênnung’s Materia Medica in 28th century B.C. -
An Endangered Orchid
Asian Journal of Conservation Biology, December 2020. Vol. 9 No. 2, pp. 275-279 AJCB: FP0144 ISSN 2278-7666 ©TCRP Foundation 2020 Asymbiotic Seed Germination, Mass propagation and Conservation of Fox-tail orchid, Rhynchostylis retusa L. Blume: An endangered orchid Kumari Fonseka* Department of Crop Science, Faculty of Agriculture, University of Ruhuna, Sri Lanka (Received: May 25, 2020; Revised: June 23, 2020; Accepted: July 22, 2020) ABSTRACT Experiments were carried out to identify the correct maturity stage for in-vitro seed germination and to develop an in-vitro protocol for mass propagation of Rhynchostylis retusa. After hand pollination of the flowers the length, girth and color changes of the pod were observed in weekly intervals in order to determine the morpho- logical indicators for maturity. In-vitro seed germination was done 3, 4, 5, 6 and 7 months after pollination on nine media viz 1. Murashige and Skoog medium (MS) 2. MS with PVP (2g/L) 3. MS with charcoal (2g/L) 4. Knudson C medium (KNC) 5.KNC with PVP (2g/L) 6. KNC with charcoal (2g/L) 7. KNC with banana extracts (75g/L) 8.Vacin and Went medium (V&W) 9. V&W with banana extract (75g/L) and coconut water (150ml/L). Results revealed that six months after pollination was the best stage for in-vitro seed germination of R. retusa. Significant germination was observed only on MS with PVP, MS with charcoal, KNC with banana extracts and V&W with banana extracts and coconut water (p ≤ 0.05). KNC with banana extracts and V&W with banana extracts and coconut water gave 100% seed germination. -

In nature, orchid seed germination is obligatory following infection by mycorrhizal fungi, which supplies the developing embryo with water, carbohydrates, vitamins, and minerals, causing the seeds to germinate relatively slowly and at a low germination rate. ,e nonsymbiotic germination of orchid seeds found in 1922 is applicable to in vitro propagation. ,e success of seed germination in vitro is influenced by supplementation with organic compounds. Here, we review the scientific literature in terms of the contents and role of organic supplements in promoting seed germination, protocorm development, and seedling growth in orchids. We systematically collected information from scientific literature databases including Scopus, Google Scholar, and ProQuest, as well as published books and conference proceedings. Various organic compounds, i.e., coconut water (CW), peptone (P), banana homogenate (BH), potato homogenate (PH), chitosan (CHT), tomato juice (TJ), and yeast extract (YE), can promote seed germination and growth and development of various orchids. -

Department of Tourism Tawang ,A Complete Guidelines ➢ DIRECTORY 1. Tourist Information Centre - 03794-222567 ➢ TOURISM 1. How to Reach. Considering its geographic location, Guwahati, the capital of Assam State may be rightfully termed as the gateway to Tawang forthe majority of the tourists planning to visit Tawang. It is approximately 543 Kms. from Tawang and is well connected by Air with direct daily flights from New Delhi and Kolkata and single stop flights coming from Mumbai, Chennai, Bangalore, Hyderabad, Jaipur etc. which are operated by all the Airlines of the country like Air India, Indigo, Jet Airlines, Spice jet, Go Air etc. with more additions in number of flights and operators expected due to launch of new private airlines in the country. Besides Air connectivity, Guwahati is also very well connected with other major cities like Delhi, Chennai, Kolkata, Jammu, Bangalore, Secundrabad etc. through the vast network of the Indian Railways After reaching Guwahati, one can reach Tawang through the following alternative modes. 1. By Helicopter:The Arunachal Pradesh Helicopter Service is operational from Guwahati Airport and presently the Helicopter services operate from Tawang to Guwahati and back on Monday, Tuesday, Thursday and Friday. However due to the limited number of seats (on an average 10 – 12 only ) it is advisable that the tickets are pre-booked by calling the Counter at the Guwahati airportor the Aviation officer at Tawang and thereafter paying the ticket charges at the Counter as till now online booking of tickets has not been started by the State Government. The Helicopter journey to Tawang over Bhutan takes around 55 minutes and local transport at Tawang can be arranged by the concerned Hotel / Tour Operator. -

Thakur & Dongarwar RJLBPCS 2019 www.rjlbpcs.com Life Science Informatics Publications Original Research Article DOI: 10.26479/2019.0502.28 SPECIES SPECIFIC POLLINATION AND SEED GERMINATION IN RHYNCHOSTYLIS RETUSA BLUME (ORCHIDACEAE) Thakur U N1*, Dongarwar N M2 1. Department of Botany, Institute of Science, Nagpur, Maharashtra, India. 2. Department of Botany, Rashtrasant Tukadoji Maharaj Nagpur University, University Campus, Amravati Road, Nagpur, Maharashtra, India. ABSTRACT: Natural pollination in Orchidaceae is coevolved with the pollinator and this coevolution sometime leads to the decline of orchid species as their pollinator is declining regularly. In present investigation pollination biology of Rhynchostylis retusa was studies. Different ages of pollinia and stigma were used for artificial pollination. Capsule developed by artificial pollination was subjected to asymbiotic seed germination prior to capsule dehiscence. Different parameters were studied as per the nutritional need of the taxa like five asymbiotic media (Vacin and Went, Modified Knudson C, ½ MS, Lindeman and BM1), three photoperiods (0/24, 16/8, 24/0 h L/D) for asymbiotic germination and three photoperiods (8/16, 12/12, 16/8 h L/D) were examined for seedling development. Seed germination percentage was highest on BM1 and ½ MS (BM 1, 86.66±1.20%) (½ MS, 79.01±6.08%). KEYWORDS: Artificial, Pollination, Asymbiotic, Germination, Seed.
