Canola : Golden Oil For Farmers And Consumers, Paul Carmody

Journal of the Department of Agriculture, Western Australia, Series 4

It is feasible that canola could become Western Australia's fourth largest crop after wheat, barley and lupins by the turn of the century.

Without the stigma attached to its parent crop, rapeseed, canola has also become one of the most successful international agricultural product launches, proving itself not only a useful cropping alternative but a healthy oil for consumers. State Oilseeds Adviser PAUL CARMODY sets the scene.

Planting Seeds For A Sound Future, Peter Portmann

Journal of the Department of Agriculture, Western Australia, Series 4

Royalties have been collected sales of all new crop varieties released in We tern ustralia by the Department of Agriculture since the lease of Merrit lupins and Yilgarn oats in 1991.

Many questions have been raised by farmers about these royalties. Why pay royalties when we have already paid for the development of the varieties through our Grains Research end: Development Corporation levy? Why should we pay a Jevy if it - is just going back into Government revenue? Is there any real benefit to us?

Wiping Out Tall Weeds, Brad Rayner

Journal of the Department of Agriculture, Western Australia, Series 4

Control of weeds is an on-going battle for farmers, with many weapons becoming increasingly expensive. A refreshing exception to this trend is the blanket wiper, a cheap but effective meens of applying herbicides to taller weeds in pasture. Brad Rayner explains how it works.

Value Of Saltbush Questioned, Brian Warren, Tess Casson, Ed Barrett-Lennard

Journal of the Department of Agriculture, Western Australia, Series 4

Over the last 20 years the Department of Agriculture has focused on finding plant species that can grow on salt/and to produce sheep feed, and on techniques for establishing plantations of saltbushes. Some research has been in response to farmer reports of success in using revegetated salt/and to provide autumn forage, while other work has resulted from the apparent importance of saltbushes in rangeland areas.

Objective measurements of wool production have been taken only recently. Three years research at Katanning indicates that while saltbush material is selected and eaten by sheep, its value for wool production is not high. It …

Wood Anatomy Of Caryophyllaceae: Ecological, Habital, Systematic, And Phylogenetic Implications, Sherwin Carlquist

Aliso: A Journal of Systematic and Floristic Botany

Wood of Caryophyllaceae is more diverse than has been appreciated. Imperforate tracheary elements may be tracheids, fiber-tracheids, or libriform fibers. Rays may be uniseriate only, multiseriate only, or absent. Roots of some species (and sterns of a few of those same genera) have vascular tissue produced by successive cambia. The diversity in wood anatomy character states shows a range from primitive to specialized so great that origin close to one of the more specialized families of Chenopodiales, such as Chenopodiaceae or Amaranthaceae, is unlikely. Caryophyllaceae probably branched from the ordinal clade near the clade's base, as cladistic evidence suggests. Raylessness …

Trichomes Of Nama (Hydrophyllaceae) That Produce Insect-Active Compunds, Bradley F. Binder

Aliso: A Journal of Systematic and Floristic Botany

Nama hispidum, N. lobbii, N. rothrockii, and N. xylopodum have two basic types of trichomes on the adaxial and abaxial surfaces: glandular and nonglandular. Nama hispidum and N. xylopodum have (1) short semierect or intermediate-length acicular trichomes that often recurve toward the leaf surface and (2) short-stalked capitate glands. The larger acicular trichomes have micropapillae. Nama lobbii has long filiform trichomes and sessile capitate glands. Nama rothrockii has erect, smooth subulate trichomes and long-stalked capitate glands. Morphological diversity of trichomes in Nama and their possible functional significance as a predator defense are discussed.

Corylophomyces, A New Dioecious Genus Of Laboulbeniales On Corylophidae (Coleoptera), Richard K. Benjamin

Aliso: A Journal of Systematic and Floristic Botany

A new dioecious genus of Laboulbeniaceae (Laboulbeniales), Corylophomyces, was established to accommodate five species parasitizing Corylophidae (Coleoptera; Cucujoidea): C. peyerimhoffii (≡Cryptandromyces peyerimhoffit); C. sericoderi (≡Autophagomyces sericoderi); C. sarawakensis (≡A. sarawakensis); and two new species, C. reflexus and C. weirii. A key to the taxa was given and all were illustrated with line drawings. Corylophomyces was placed in Amorphomycetinae sensu Tavares. The other genera included in this subtribe by Tavares in 1985, i.e., Amorphomyces, Dioicomyces, Nanomyces, Rhizopodomyces, and Tetrandromyces, were compared with one another and with the new genus.

Wood And Bark Anatomy Of Ranunculaceae (Including Hydrastis) And Glaucidiaceae, Sherwin Carlquist

Aliso: A Journal of Systematic and Floristic Botany

Wood anatomy of 14 species of Clematis and one species each of Delphinium, Helleborus, Thalictrum, and Xanthorhiza (Ranunculaceae) is compared to that of Glaucidium palma tum (Glaucidiaceae) and Hydrastis canadensis (Ranunculaceae, or Hydrastidaceae of some authors). Clematis wood has features typical of wood of vines and lianas: wide (earlywood) vessels, abundant axial parenchyma (earlywood, some species), high vessel density, low proportion of fibrous tissue in wood, wide rays composed of thin-walled cells, and abrupt origin of multiseriate rays. Superimposed on these features are expressions indicative of xeromorphy in the species of cold or dry areas: numerous narrow latewood vessels, presence …

Vascular Flora Of The San Mateo Canyon Wilderness Area, Cleveland National Forest, California, Steve Boyd, Timothy S. Ross, Orlando Mistreta, David Bramlet

Aliso: A Journal of Systematic and Floristic Botany

The Santa Ana Mountains, as a whole, have been well-studied floristically. Little work, however, has been conducted previously in the southwestern portion of the range which includes the San Mateo Canyon Wilderness Area of the Cleveland National Forest.

New Fungi From Dasylirion (Agavaceae), Annette W. Ramaley

Aliso: A Journal of Systematic and Floristic Botany

Dead leaves of Dasylirion were collected in Texas in Guadalupe Mountains National Park and Big Bend National Park, and in the Valley of Fires, New Mexico. The fungi present were identified and grown in culture to identify teleomorph-anamorph connections. Four new ascomycete species are described—Graphyllium dasylirionis, Splanchnonema dasylirionis, Chaetoplea dasylirionis, and Chaetoplea sotolifoliorum. In addition, a new genus, Parahendersonia, is described to accommodate the coelomycete anamorph of Chaetoplea dasylirionis.

Pulses : Profitable New Crops For The Wheatbelt, Kadambot Siddique, Stephen Loss, Ian Pritchard

Journal of the Department of Agriculture, Western Australia, Series 4

Narrow-leafed lupins have beeb produced on sandy acid soils throughout the wheatbelt for more than two decades. However, the wheatbelt contains large areas ofsoilsnot suited to narrow-leafed lupins. For several years reasearchers have been examining alternatives to narrow-leafed lupins for these soils.

Kadambot Siddique, Stephen Loss and Ian Prichard look at production of these new grain legumes, known as pulses.

Dan Carter reports on the widespread damage to soils and property, and management practices that would have reduced the problem.

Cucumber Mosiac Virus In Lupins, Annette Bwye, Roger Jones, Wayne Proudlove

Journal of the Department of Agriculture, Western Australia, Series 4

Cucumber mosaic virus is a threat to lupin crops from Geraldton to Esperance, particularly to those growing in areas receiving more than 400 mm average annual rainfall. The disease markedly decreases grain yield in narrow-leafed and yellow lupins but doesnot infect albus or sandplain lupins. Worldwide , after bean yellow mosaic virus, cucumber mosaic virus is the second most important virus affecting lupins. Annette Bwye, Roger Jones and Wayne Proudlove outline the symptoms, spread and management of this serious disease.

Wood Anatomy Of Berberidaceae: Ecological And Phylogenetic Considerations, Sherwin Carlquist

Aliso: A Journal of Systematic and Floristic Botany

Qualitative and quantitative data are presented for 21 collections of Berberis and one each of Epimedium, Jeffersonia, and Nandina. Most species of Berberis have large numbers of narrow vessels ~ixed with vasicentric tracheids. Scalariform perforation plates are reported here only for Epimedium, m wh1ch they are occasional. Berberidaceae have living fibers (Berberis), fiber-tracheids plus living fibers (Nandina), or tracheids (Jeffersonia) as imperforate tracheary elements. Axial parenchyma is reported here for Jeffersonia and one species of Berberis. Previous reports of axial parenchyma in Berberis and Nandina likely refer to undivided living fibers, mostly intermixed with vessels, which are slightly shorter and …

Journal of the Arkansas Academy of Science

Carnations (Dianthus caryophyllus L.) are among the most widely used cut flowers in the world. Tissue culture techniques offer an efficient method for the micropropagation of carnations. This study was conducted to test the effect of thidiazuron (TDZ) and benzylaminopurine (BAP), artificial cytokinins, on shoot multiplication of two carnation cultivars, Barlo II Nora and Raggio di Sole. Isolated axillary buds were cultured on Gamborg's (B-5) basal medium supplemented with 30 g/L sucrose and 8 g/L agar. The cultures were maintained at a 10-h photoperiod (40 (mu-Em2s-1) and 23°C±2C°. Number of multiple shoots produced was dependent upon the genotype and was …

Callus Induction And Plant Regeneration Of Commercial Rice (Oryza Sativa L.) Cultivars, Jameel M. Al-Khayri, Edwin J. Anderson

Journal of the Arkansas Academy of Science

Manipulation of agronomic traits at the cellular and molecular levels offers an efficient approach to enhance conventional breeding efforts for rice improvement. Plant regeneration protocols, required for biotechnological applications, have not yet been developed for a number of important rice cultivars. This study was conducted to establish a system for plant regeneration of elite rice cultivars adapted to the southern U.S.A. Callus was induced from dehusked grains of cultivars Alan, Katy, and LaGrue, on MS media containing 0.5, 2, and 4 mg L-1 2,4-D, with 0.5 mg L-1 kinetin or without kinetin. Plant regeneration was accomplished by transferring the callus …

Checklist And Distribution Of Arkansas Pteridophytes, James H. Peck, W. Carl Taylor

Journal of the Arkansas Academy of Science

Over the past 14 years, an effort was made to summarize and improve our knowledge of the Arkansas pteridophyte flora beyond that developed by Taylor and Demaree (1979). They presented a flora of 68 species plus 2 varieties plus 4 hybrids, for a total of 74 taxa vouchered with 1335 county-level occurrence records. Changes in accepted nomenclature, field work, and herbaria searches have added as new to the flora 10 species plus 1 variety plus 7 hybrids, supported with 74 county-level occurrence records. Another 815 county-level occurrence records were added to the known flora. The Arkansas pteridophyte flora now consists …
