Sykora, Optimizing grassland management for flower-visiting insects in roadside verges, Biological Conservation, Volume 142, Issue 10, October 2009, Pages 2097-2103, ISSN 0006-3207, DOI: 10.1016/j.biocon.2009.04.009. (http://www.sciencedirect.com/science/article/B6V5X-4WBB71H- 1/2/3622bace9a5f6c088d770bcaa28dcc2f) Abstract: The decline of flower-visiting insects is a threat to ecological processes and to the services these insects provide. Roadside verges in the Netherlands span approximately 80,000 km and are often covered with semi-natural grasslands. As such, they also provide a suitable habitat for many insects, but this has received little attention so far. We investigated the effects of different management treatments on flower-visiting insects. We studied flower visitation in a 3 years old experimental set-up with five mowing treatments each replicated five times. Management types were: no management and mowing once or twice per year with and without the removal of hay, representing common forms of management and neglect. During an entire growing season, both flowers (number of species and inflorescences) as well as insects (total abundance and actual flower visits) were investigated. Mowing twice per year with removal of hay showed highest values for all measured variables and this effect persisted throughout the growing season. The early summer cut proved to be very important for insect feeding opportunities, due to the re-flowering of plants later in the growing season. Flower abundance showed high correlations with both plant species richness and the number of insect visits. Although overall, mowing twice a year with hay removal was the most beneficial treatment for flower-visiting insects, these plots were entirely devoid of flowers for some period right after mowing, indicating that a rotational scheme might further promote insect diversity and abundance.

(http://www.sciencedirect.com/science/article/B6WMV-4W04KS5- 4/2/b02c39e16e3c25208dd3df444d6ebce6) Abstract: While beneficial health properties of tea leaves have been extensively studied, less attention has been given to that of flowers of the tea (Camellia sinensis) plant. In this work, the ethanolic extract and its ethyl acetate-soluble fraction (EEA) from the tea flowers were found to possess the potent antioxidant activity using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical-scavenging assay. The compounds present in EEA had comparatively strong DPPH scavenging activity and strongly contributed to the antioxidant activity of the tea flowers. From EEA, besides eight catechins, five flavonol glycosides were isolated and their structures were elucidated on the basis of mass spectrometry and nuclear magnetic resonance spectroscopy as myricetin 3-O-[beta]-d- galactopyranoside, quercetin 3-O-[beta]-d-galactopyranoside, kaempferol 3-O-[beta]-d- galactopyranoside, kaempferol 3-O-[beta]-d-glucopyranoside, and kaempferol 3-O-[[alpha]-l- rhamnopyranosyl-(1-6)-[beta]-d-glucopyranoside]. In addition, epigallocatechin gallate and epicatechin gallate were found as the major active components responsible for the antioxidant activity of tea flowers through the use of a combination of preparative liquid chromatography separation and DPPH assay.

(http://www.sciencedirect.com/science/article/B6TBJ-4WWFN41- 1/2/2542334da441024a41dd2810623883d7) Abstract: Nanometer-sized silver (Ag+) particles (NS) are used in various applications as an anti-microbial. Effects of NS (2-5 nm diam.) pulse solution treatments on vase life of cut gerbera (Gerbera jamesonii) cv. Ruikou flowers were investigated. Compared with the control [pulsed with deionised water (DI) and subsequently held in DI] pulsing for 24 h with 5 mg/L NS solution followed by holding in DI maintained water uptake and extended vase life. From in vitro and microscopy assessments, NS pulse treatment inhibited bacteria growth in the vase solution and at cut stem ends during the first 2 d of the vase period.

(http://www.sciencedirect.com/science/article/B6TC3-4WPS9P3- 1/2/a377ee4be6537dda938823a6a06bfc50) Abstract: Photoperiod is commonly controlled in the commercial production of ornamental crops to induce or prevent flowering. Flower induction in short-day (SD) plants can be prevented or delayed when the natural daylength is short by providing low-intensity lighting during the dark period. A stationary high-pressure sodium (HPS) lamp with an oscillating aluminum parabolic reflector (cyclic HPS) has been developed to provide intermittent lighting to greenhouse crops. We determined the efficacy of a cyclic HPS lamp at preventing flowering in SD plants garden chrysanthemum [Chrysanthemum x grandiflorum (Ramat.) Kitam.] `Bianca', pot chrysanthemum `Auburn', and velvet sage (Salvia leucantha L.) relative to traditional night interruption (NI) lighting strategies. Plants were grown in a glass-glazed greenhouse at a mean daily temperature of 19.5-20.7 [degree sign]C with natural SD photoperiods. NI lighting was delivered during the middle of the night (2230-0230 h) from a 600 W cyclic HPS lamp mounted at one gable end of the greenhouse or from incandescent (INC) lamps that were illuminated for the entire 4 h (CONT INC) or for 6 min every 30 min for 4 h. Plants under cyclic HPS were grown at lateral distances of 1, 4, 7, 10, or 13 m from under the lamp. Control plants were grown under an uninterrupted 15 h skotoperiod. As the distance from the cyclic HPS lamp increased from 1 to 13 m, the maximum irradiance measured during the NI decreased from 25.4 to 0.3 [mu]mol m-2 s-1 and time to visible inflorescence (VI) and the number of nodes at VI decreased. All species had a VI within 54 d, but <=10% of plants flowered when grown at a lateral distance of 1 or 4 m from the cyclic HPS lamp or under CONT INC. Plants grown without NI had a VI 2 to 15 d earlier and flowered 7 to 24 d earlier than plants grown at 10 or 13 m from the cyclic HPS. All garden chrysanthemums flowered under cyclic INC, whereas velvet sage and pot chrysanthemum had 15% and 35% flowering, respectively. These results indicate that a cyclic HPS lamp can be used effectively to delay flower induction and prevent flowering in these species when NI is delivered at >=2.4 [mu]mol m-2 s-1.

(http://www.sciencedirect.com/science/article/B6TC3-4WDFCFJ- 2/2/3cbd275447932e6a97ba809154f8a690) Abstract: The genus Ptilotus has immense potential for ornamental horticulture but its commercial development has been hindered by propagation limitations. Poor seed quality and germination are reported. Cutting propagation is limited by cutting supply as the juvenile phase of Ptilotus is short. Micropropagation has been used in an attempt to overcome these difficulties but explants become floral in vitro and this causes plantlets to elongate. Ethephon has been used to control flowering of stock plants of many ornamental species. This study investigated the effect of ethephon applied to young (3-week-old, deflasked from tissue culture) and mature (1-year-old) Ptilotus plants in a greenhouse. A system of applying gaseous ethylene at 0, 100, 200 and 300 mg l-1 to the headspace of in vitro plantlets in glass jars was developed and the response of in vitro plantlets to ethylene studied. One-year-old Ptilotus plants were treated with 500 mg l-1 ethephon 2 days before pruning or 1 or 2 weeks after pruning. Ethephon application 2 days before pruning decreased the number of inflorescences and increased the number of shoots (compared to the control) but was phytotoxic. Ethephon applications of 150 or 300 mg l-1 applied weekly or fortnightly to 3-week-old plants deflasked from tissue culture reduced plant height and number of inflorescences and at low concentrations increased the number of new shoots. A fortnightly application at 150 mg l-1 is recommended. Previous reports on the effects of ethylene on inflorescence production on plantlets in vitro are limited. Our study showed that exposure of in vitro plantlets of P. nobilis to ethylene gas at 100 mg l-1 for 1 h significantly increased the number of shoots and plant height but this did not occur for plantlets of P. spicatus. Plantlets of P. spicatus exposed to transient ethylene at 200 and 300 mg l-1 showed significantly greater rooting (52.4%) than the control (13.6%).

Thiele Western Australian Herbarium, Department of Environment and Conservation, Locked Bag 104, Bentley Delivery Centre, Western Australia 6983 Email: [email protected] Abstract Thiele, K.R. Darwinia hortiorum (Myrtaceae: Chamelaucieae), a new species from the Darling Range, Western Australia. Nuytsia 20: 277–281 (2010). The distinctive, new, rare species Darwinia hortiorum is described, illustrated and discussed. Uniquely in the genus it has strongly curved- zygomorphic flowers with the sigmoid styles arranged so that they group towards the centre of the head-like inflorescences. Introduction Darwinia Rudge comprises c. 90 species, mostly from the south-west of Western Australia with c. 15 species in New South Wales, Victoria and South Australia. Phylogenetic analyses (M. Barrett, unpublished) have shown that the genus is polyphyletic, with distinct eastern and western Australian clades. Along with the related genera Actinodium Schauer, Chamelaucium Desf., Homoranthus A.Cunn. ex Schauer and Pileanthus Labill., the Darwinia clades are nested in a paraphyletic Verticordia DC. Many undescribed species of Darwinia are known in Western Australia, and these are being progressively described (Rye 1983; Marchant & Keighery 1980; Marchant 1984; Keighery & Marchant 2002; Keighery 2009). A significant number of taxa in the genus are narrowly endemic or rare and are of high conservation significance. Although taxonomic reassignment of the Western Australian species of Darwinia may be required in the future, resolving the status of these undescribed species and describing them under their current genus helps provide information for conservation assessments and survey.

  • Inselbergs) As Centers of Diversity for Desiccation-Tolerant Vascular Plants
    Plant Ecology 151: 19–28, 2000. 19 © 2000 Kluwer Academic Publishers. Printed in the Netherlands. Dedicated to Prof. Dr Karl Eduard Linsenmair (Universität Würzburg) on the occasion of his 60th birthday. Granitic and gneissic outcrops (inselbergs) as centers of diversity for desiccation-tolerant vascular plants Stefan Porembski1 & Wilhelm Barthlott2 1Universität Rostock, Institut für Biodiversitätsforschung, Allgemeine und Spezielle Botanik, Rostock, Germany (E-mail: [email protected]); 2Botanisches Institut der Universität, Bonn, Germany (E-mail: [email protected]) Key words: Afrotrilepis, Borya, Desiccation tolerance, Granitic outcrops, Myrothamnus, Poikilohydry, Resurrection plants, Velloziaceae, Water stress Abstract Although desiccation tolerance is common in non-vascular plants, this adaptive trait is very rare in vascular plants. Desiccation-tolerant vascular plants occur particularly on rock outcrops in the tropics and to a lesser extent in temperate zones. They are found from sea level up to 2800 m. The diversity of desiccation-tolerant species as mea- sured by number of species is highest in East Africa, Madagascar and Brazil, where granitic and gneissic outcrops, or inselbergs, are their main habitat. Inselbergs frequently occur as isolated monoliths characterized by extreme environmental conditions (i.e., edaphic dryness, high degrees of insolation). On tropical inselbergs, desiccation- tolerant monocotyledons (i.e., Cyperaceae and Velloziaceae) dominate in mat-like communities which cover even steep slopes. Mat-forming desiccation-tolerant species may attain considerable age (hundreds of years) and size (several m in height, for pseudostemmed species). Both homoiochlorophyllous and poikilochlorophyllous species occur. In their natural habitats, both groups survive dry periods of several months and regain their photosynthetic activity within a few days after rainfall.
