Fasciation. Lumina C
346 The Ohio Naturalist. [Vol. III, No. 3, FASCIATION. LUMINA C. RIDDLE. The phenomena of fasciation are sufficiently striking to attract the attention of the most casual observer, and the malformation occurs so frequently that nearly every person has seen one or more cases of it. It manifests itself usually by a remarkable broadening and flattening of the stem, crowded phyllotaxy and often spiral twisting and splitting of this broadened axis, although the portion of the plant affected and the exact character of the growth varies with the nature of the plant. Those having the rosette habit throughout their entire life, as the common dande- lion, show fasciation in the peduncle of the inflorescence. In the thistle (Fig. 2,) which has the rosette habit during the first year Fig. 1. a. Ailanthus glandulosus. b. Ranunculus abortivus, and is stemmed during the second year, it has only been observed in the second year's growth and affected the entire stalk. In the herbaceous hollow-stemmed plant of Ranunculus abortivus, {Fig. 1, b,) the entire stem was found fasciated and inside was found a reversed cylinder having the delicate epidermal layer within and a well developed ring of fibro-vascular tissue surround- ing it. In Erigeron philadelphicus the leaves were so closely Jan., 1903.] Fasciation. 347 compacted that the stem was entirely concealed while the top of the stalk was twisted down.

http://www.gardenorganic.org.uk/organicweeds The biology and non-chemical control of Goat’s-beard (Tragopogon pratensis L.) W Bond & G Davies HDRA, Ryton Organic Gardens, Coventry, CV8, 3LG, UK Goat’s-beard (buck’s-beard, common goatsbeard, Jack-go-to-bed-at-noon, meadow goat’s-beard, meadow salsify, noon flower) Tragopogon pratensis L. Occurrence Goat’s-beard is an annual, biennial or monocarpic perennial, native in grassy places, on roadsides and in rough and cultivated land (Stace, 1997; Clapham et al., 1987). There are 3 subspecies of which ssp. minor is the native form that is common in most of Britain. Goat’s-beard grows on a variety of soil types ranging from sand to clay. Hybrids may result from crosses with other Tragopogon species. The root and leaves have been eaten by man (Barker, 2001). Biology Goat’s-beard flowers from June to July in the UK (Clapham et al., 1987; Barker, 2001) and May to September in Canada (Frankton & Mulligan, 1977). Flowering usually occurs in the second or subsequent year of growth (Clements et al., 1999). There is a minimum root crown diameter at which flowering occurs but this varies from year to year because other factors are involved. The flowers are insect pollinated. The plants senesce after producing seeds. Each compound flower head (capitulum) contains 20-127 seeds (Clements et al., 1999). Average seed numbers per plant range from 100 to 850. Pawlowski et al. (1970) give the seed number for an average plant as 1,266. Two seed types are produced that differ in morphology. -

RARE SPECIES AS EXAMPLES OF PLANT EVOLUTION G. Ledyaid Stebbins' .\bstract.- Rare species, including endangered ones, can be very valuable sources of information about evolution- arv processes. They may be rare and valuable because: (1) they are evolutionary youngsters and could represent an entirelv new evolutionary strategy of great scientific and practical value; (2) they are evolutionary relicts that have stored enormous amounts of genetic information of great worth; (3) they may represent endemic varieties that har- bor a great deal of the genetic variability in the gene pool that would be of enormous value to a plant geneticist; the rarity of the plant is not necessarily correlated with the size of its gene pool; (4) they may represent unique ecologi- cal adaptations of great value to future generations. Studies of gene pools and the genetics of adaptation constitute a new and developing field of the future. -
COVER CROPS and SOIL-BORNE FUNGI DANGEROUS TOWARDS the CULTIVATION of SALSIFY (Tragopogon Porrifolius Var
Acta Sci. Pol., Hortorum Cultus 10(2) 2011, 167-181 COVER CROPS AND SOIL-BORNE FUNGI DANGEROUS TOWARDS THE CULTIVATION OF SALSIFY (Tragopogon porrifolius var. sativus (Gaterau) Br.) Elbieta Patkowska, Mirosaw Konopiski University of Life Sciences in Lublin Abstract. Salsify has a remarkable taste and nutritious values. It is a rich source of inulin – a glycoside which has a positive effect on human and animal organisms. The paper pre- sents studies on the species composition of soil-borne fungi infecting the roots of Tragopogon porrifolius var. sativus cultivated with the use of oats, tansy phacelia and spring vetch as cover crops. In a field experiment the cover crops formed abundant green mass before winter and it constituted a natural mulch on the surface of the plough land. It was managed in two ways: 1) mixed with the soil as a result of spring ploughing, or 2) mixed with the soil as a result of pre-winter ploughing. The conventional cultivation of salsify, i.e. without cover crops, constituted the control. The studies established the number and health status of four-week-old salsify seedlings and roots with necrotic signs. A laboratory mycological analysis made it possible to determine the quantitative and qualitative composition of fungi infecting the underground parts of Tragopogon porri- folius var. sativus. The emergences and the proportion of infected salsify seedlings varied and depended on the species of the mulching plant. The smallest number of infected seed- lings was obtained after the mulch with oats, slightly more after the application of spring vetch or tansy phacelia as cover crops, and the most in the control. -
Inf.9 Proposal from Germany
INF.9 PROPOSAL FROM GERMANY This proposal reflects the wish of delegates expressed during the 56 th session of the Specialized Section: – to elaborate a standard for root vegetables other than carrots, – to include the tubercle vegetables. The intention of this standard for root and tubercle vegetables is, to integrate the existing UNECE standards for scorzonera (FFV-33), horse-radish (FFV-20), and radishes (FFV-43). Thus, while approving this draft standard as new UNECE standard, these standards should be withdrawn. UNECE STANDARD FFV-No concerning the marketing and commercial quality control of ROOT AND TUBERCLE VEGETABLES 1 I. DEFINITION OF PRODUCE This standard applies to root and tubercle vegetables of varieties (cultivars) grown from the following species to be supplied fresh to the consumer, root and tubercle vegetables for industrial processing being excluded: – beet tubercle ( Beta vulgaris L. ssp. vulgaris var. vulgaris und var. lutea DC.), – celeriac ( Apium graveolens L. var. rapaceum (Mill.) Gaudin), – Hamburg parsley ( Petroselinum crispum (Mill.) Nyman ex A. W. Hill var. tuberosum (Bernh.) Mart Crov.), – horse-radish ( Armoracia rusticana Gottfr. Gaertn., B. Mey. et Scherb.), – kohlrabi, cabbage turnip (Brassica olearacea var. gongylodes L.) – parsnips ( Pastinaca sativa L.), – radishes ( Raphanus sativus L. var. sativus ), – radishes ( Raphanus sativus var. niger (Mill.) J. Kern.). – salsify ( Tragopogon porrifolius L. ssp. porrifolius ), – scorzonera ( Scorzonera hispanica L.), – swede ( Brassica napus L. (Napobrassica-group)), – turnips ( Brassica rapa L. (Rapa-group)), – turnip-rooted chervil or bulbous chervil ( Chaerophyllum bulbosum L.), – root and tubercle vegetables of other species and any hybrids. II. PROVISIONS CONCERNING QUALITY 1 Note: For carrots ( Daucus carota L.) the UNECE standard FFV-10 applies. -

Mihail Sadoveanu, nr. 3, 700490–Iaşi, Romania Corresponding author: [email protected] This second part of the paper about the vascular flora of Rarău Massif listed approximately half of the whole number of the species registered by the authors in their field trips or already included in literature on the same area. Other taxa have been added to the initial list of plants, so that, the total number of taxa registered by the authors in Rarău Massif amount to 1443 taxa (1133 species and 310 subspecies, varieties and forms). There was signaled out the alien taxa on the surveyed area (18 species) and those dubious presence of some taxa for the same area (17 species). Also, there were listed all the vascular plants, protected by various laws or regulations, both internal or international, existing in Rarău (i.e. 189 taxa). Finally, there has been assessed the degree of wild flora conservation, using several indicators introduced in literature by Nowak, as they are: conservation indicator (C), threat conservation indicator) (CK), sozophytisation indicator (W), and conservation effectiveness indicator (E). Key words: Vascular flora, Rarău Massif, Romania, conservation indicators. 1. INTRODUCTION A comprehensive analysis of Rarău flora, in terms of plant diversity, taxonomic structure, biological, ecological and phytogeographic characteristics, as well as in terms of the richness in endemics, relict or threatened plant species was published in our previous note (see Oprea & Sîrbu 2012). -
