Biotechnological strategies of propagation may satisfy the market demand and are useful for conservation programs. Hypothesis: Vigorous seedlings of S. hernandezii can be produced in vitro by asymbiotic seed germination techniques and the addition of chitosan to the culture medium in the temporary immersion system (RITA®) and in semi-solid medium systems. Methods: The first step was the in vitro germination of seeds obtained from a mature capsule of wild plants, followed by multiplication via adventitious protocorm induction known as protocorm-like bodies, using plant growth regulators. For this purpose, we utilized Murashige and Skoog (MS) basal medium amended with 0.5 mg/L α-Naphthaleneacetic acid, combined with different concentrations of 6- Benzylaminepurine (1, 3, and 5 mg/L). -

P.: 481; 86047-902; Londrina – PR - Brasil ABSTRACT Orchids are valuable pot plants and Cattleya intermedia is a promising species underused in breeding programs. Recently, breeding work with this species produced superior plants that are believed to be not the true species owing to the morphological differences from wild plants. The aim of this study was to estimate the level of genetic diversity and interrelationships between wild and bred Cattleya intermedia collected at three different Brazilian states and from commercial breeders with RAPD markers. A total of 65 polymorphic bands were used to generate a genetic distance matrix. No specific groupings were revealed by the cluster analysis as bred materials were not different from wild plants. The genetic differentiation (F ST = 0.01626) was very low indicating a high gene flow in C. intermedia due to artificial crosses and a high differentiation between populations. The genetic variability available within this species is high enough to allow genetic progress in flower shape and size. Key words: Fst , domestication, molecular markers, genetic variability, orchids INTRODUCTION including Sophronitis sensu van den Berg, van den Berg, 2008). Orchidaceae is the largest botanical family ranging Cattleya intermedia is native from the South from 7 to 10 percent of the flowering plant species Atlantic rainforest, a biodiversity hotspot highly (Dressler, 1993; 2005). -

In last place was gravel, which was in fourth place for all four parameters assessed. For L. purpurata, the substrates with the greatest number of parameters in first and second positions were gravel:peat and peat, both with two first positions, one second and one third. Next was xaxim, which had one second position, two third positions and one fourth. As the last came gravel, which had one second position and three fourth positions. Xaxim was the best substrate for C. forbesii, but could be replaced, with a minor reduction in performance, by the no. -

Received 25 July, 2016; Accepted 21 September, 2016 Orchids are among the most beautiful flowers and endangered due to habitat destruction and over- collection. Cattleya walkeriana is one of the most beautiful flowers joining the small sized plant with medium large and heavily scented flowers. It is widely known and appreciated by its beautiful clones and it has much to offer to breeders because their plants have besides other attributes as small habit and big flowers, many colour variations, form and precocity, becoming flower only four years in ex vitro culture. However, in some of the original places it is becoming a red listed species. Notwithstanding, very little is known about the genetics of these flowers and the variability in the species that is widespread in the Brazilian territory. The aim of this work was to estimate the variability among cultivated materials using the F statistics and to verify if there was inbreeding in plant crosses with similar characteristics, employing as a tool the RAPD simple methodology. The results obtained showed that RAPD was good enough to estimate the variability in C. -

BESI, DOME NIKONG, MUSKHAZLI MUSTAFA & RUSEA GO* Department of Biology, Faculty of Science, Universiti Putra Malaysia, 43400 Serdang, Selangor Darul Ehsan, Malaysia *Corresponding author: [email protected] ABSTRACT. The uncontrolled logging in Peninsular Malaysia and the resulting mudslides in the lowland areas have been perilous, not to just humans, but also to another biodiversity, including the wild orchids. Their survival in these highly depleted areas is being overlooked due to the inaccessible and harsh environment. This paper reports on the rescue of orchids at risk from the disturbed forests for ex-situ conservation, the identification of the diversity of orchids and the evaluation of the influence of micro-climatic changes induced by clear-cut logging towards the resilience of orchids in the flood-disturbed secondary forests and logged forests in Terengganu and Kelantan, located at the central region of Peninsular Malaysia, where the forest destruction by logging activities has been extensive. -

Of all the families of plants orchids are the largest. There are an estimated 750 to 1,000 genera and more than 25,000 species of orchids known today, with the number growing each year! The largest number of species is found in the Dendrobium (1,500 spp), Bulbophyllum (1,500 spp), and Pleurothalis (1,000 spp) genera. They are found on every continent in the world with the largest variety found in Asia. There are even species which use hot springs in Greenland to grow. Orchids can be epiphytic (growing high in the trees), terrestrial (growing in the ground), lithophytes (grow on rocks), and a few are saprophytic (living off decaying vegetation). The family is prized for its beautiful and diverse flowers. The only plant with an economic value to the common man is vanilla, which is a commonly enjoyed flavoring. The hybridizing of these flowers has become a major economic force worldwide for cut flowers and cultivation of plants by hobbyists. -
Reaching a Compromise Between Conflicting Nuclear and Plastid
Phytotaxa 186 (2): 075–086 ISSN 1179-3155 (print edition) www.mapress.com/phytotaxa/ PHYTOTAXA Copyright © 2014 Magnolia Press Article ISSN 1179-3163 (online edition) http://dx.doi.org/10.11646/phytotaxa.186.2.2 Reaching a compromise between conflicting nuclear and plastid phylogenetic trees: a new classification for the genus Cattleya (Epidendreae; Epidendroideae; Orchidaceae) CÁSSIO VAN DEN BERG Departamento de Ciências Biológicas, Universidade Estadual de Feira de Santana, Av. Transnordestina s.n., Feira de Santana, Bahia, 44036-900, Brazil; e-mail: [email protected] Abstract A new classification for the 114 species Cattleya is proposed, based on and compatible with previously published nuclear, plastid and combined phylogenetic trees. Cattleya is divided into four subgenera, three sections and five series. A key to the infrageneric categories and a table listing all species and their placement is presented. Key words: Laeliinae, Laelia, Sophronitis, infrageneric classification Introduction Cattleya Lindley (1824: t. 33) is a Neotropical genus with 114 species of outstanding horticultural importance (van den Berg 2005, 2008). On the basis of molecular phylogenetic results based on nuclear internal transcribed spacer (ITS) and plastid trnL-F (intron and intergenic spacer), matK and rbcL (van den Berg et al. 2000 , van den Berg 2009, van den Berg et al. 2009), Sophronitis Lindley (1828a: t. 1147) and all Brazilian species previously included in Laelia Lindley (1831a: 115) were transferred to Cattleya (van den Berg 2008). In the last paper, the rationale justifying lumping as a better option than splitting Cattleya in smaller genera was presented. The alternative option of splitting into several genera would the number of narrowly defined genera and create many thousand nothogenera in horticulture. -
