Goth Rhizomes: Queer Differences in Minor Gothic Literature
This project identifies three minor authors in three historical periods, applying deconstructive and queer theory to their writings and to their biographies. The resulting analysis traces gothic effects through other, more familiar texts and figures in order to bring about re-readings that disrupt …

Rhizomes, Parasites, Folds and Trees: Systems of Thought in Medieval French and Catalan Literary Texts
… trees and folds; and the third with folds and rhizomes. However, resonances with the other network theories are discussed as they occur, in order to demonstrate the fundamentally interconnected and often interchangeable nature of these systems. Each chapter includes close analysis of manuscript …

A proteomic investigation of the rhizomes of the resurrection fern Mohria caffrorum L. (Desv.) in response to desiccation
… desiccation-tolerance in resurrection plant rhizomes, this work was undertaken to study the mechanisms of desiccation-tolerance in Mohria caffrorum rhizomes. Fronds of this plant have been previously characterized as being desiccation-tolerant in summer and desiccation-sensitive in winter. …

Growth of roots, rhizomes, and tillers of Kentucky bluegrass (Poa pratensis L.) cultivars and genotypes as affected by fertility level, cutting height, and season
Field experiments were established on July 12, 1971, and April 12 and April 20, 1972, by transplanting various cultivars and genotypes of Kentucky bluegrass (Poa pratensis L.). Objectives were to study effects of fertility level and cutting height on underground growth of various Kentucky …

Transcriptional regulation of seasonal desiccation tolerance in the fronds and rhizome of the fern Anemia caffrorum
… desiccation tolerance in the fronds and rhizomes was explored. In particular, rhizomes were of interest as they have been postulated as the regulator of frond phenotype (DS/DT). Fronds and rhizomes were subjected to desiccation and tissues of different water contents were collected. …

A study of mugwort: I. growth habits and control II. effects of 2,3,6-trichlorophenylacetic acid on certain respiratory enzymes
… that would prevent shoot growth from mugwort rhizomes. Also, various herbicides were evaluated in field experiments for the control of mugwort. The last study involved the effects of fenac on respiration and some respiratory enzymes. The most unifonn plants were observed from two-inch rhizome …

Investigations on the effects of Typha capensis on male reproductive functions
… and aging male symptoms. The T. capensis rhizomes are used in traditional medicine during pregnancy to ensure easy delivery, for venereal diseases, dysmenorrhea, diarrhoea, dysentery, and to enhance the male potency and libido. Typha genuses contain flavones and other phenolic compounds, …

Ecology of nitrogen-fixing bacteria associated with Miscanthus
… In order to address the objectives, both rhizomes and rhizosphere samples were collected from native Miscanthus in Taiwan and agricultural samples from Illinois. Thirty-two diazotroph strains were isolated from native Miscanthus rhizomes, and most of them were Gamma-proteobacteria. The …

Winter survival of bermudagrasses (Cynodon sp.) as influenced by deacclimation, low temperatures, and dormancy periods
… or 8 days at 27C/13C (day/night). Subsequently, rhizomes and stolons were subjected to +2, 0, -2, -4, or -6C for 24 hours. One third of the samples from each treatment were planted after 0, 45, and 90 days storage at 2.8C±1.6C. Rhizomes and stolons subjected to -4 or -6C did not survive. …

Steroidal saponins and sapogenins from Agapanthus praecox Willd
… C₅₁H₈₄O₂₄, a steroidal saponin, isolated from rhizomes of Agapanthus praecox Willd., yielded, on acid hydrolysis, the steroidal sapogenin agspanthagenin and galactose and rhamnose in the molecular ratio of 3:l. The structure assigned to agapanthagenin has been confirmed oh the basis of further …

Studies on the essential oil of Anemopsis Californica
<p>The roots and rhizomes of Anemopsis Californica (Nutt.) Hook and Arn. (family Saururaceae) have been used by the early Spanish Americans and Indians to treat a variety of ailments. The plant is commonly known as Yerba del Mansa, Yerba Mansa, or Manza.</p><p> We decided to investigate the …

Volunteer Establishment of<i> Miscanthus </i>×<i> giganteus</i> Vegetative Propagules: Implications for Biofuel Production
… vegetative propagules (plug plantlets, rhizomes, and stem cuttings) were placed under 5 cm of soil (control), underneath mulch, or on top of the soil surface (directly exposed to desiccation). Separate experiments were performed to assess the effect of competition and water addition on …

Resistance to Three Common Herbicides in Chameleon Plant (Houttuynia Cordata Thunb.), a Highly Invasive Exotic Species
… sexually through seeds and asexually through rhizomes and is invasive in multiple countries including the U.S. There has been much research on H. cordata as a medicinal species, and its potential as an invasive species is well documented. However, its herbicidal resistance has not previously …

The influence of temperature and defoliation on growth and carbohydrates of crownvetch (Coronilla varia L.) and some temperature responses of grass and legume seedlings
… root growth and acid soluble carbohydrates in rhizomes and tops were studied. Night-day temperatures of 70-80 F produced highest dry matter yields which decreased with higher and lower temperatures. Increased temperatures decreased root growth and carbohydrates in rhizomes. Total available …

Caucasian clover establishment in the high country and grazing responses in ryegrass/white clover lowland pasture
… clover and the greatest lateral spread of rhizomes. However, all plants strip and sod seeding developed rhizomes after nine months. Plants established by broadcasting were small with few rhizomes in the first season. The higher fertiliser rate improved establishment and growth, particularly …

Heavy metal phytotoxicity: the effects of lead on the common reed, Phragmites australis (Cav.) Trin. ex Steud.
… Significantly, the formation of new horizontal rhizomes was inhibited and this caused the decline of the dosed reed stand. This effect was promoted through various feedback mechanisms involving the number and size of apical and axillary buds, the density of shoot tillering, and the proportions …

Characterization of two genes, trehalose-6-phosphate synthase/phosphatase and nucleotide binding protein, shown to be differentially regulated in roots of Cypripedium parviflorum var. pubescens grown with a mycorrhizal fungus Thanatephorus pennatus
… high expression in roots and low expression in rhizomes and leaves. The NuBP gene exists as a single copy and has a low level of expression in rhizomes and leaves. Expression of Tps is induced by sucrose, but reduced by trehalose. Cultivation of CyPP with non-mycorrhizal fungi did not affect …
