Comparative Anatomy And Systematics Of Picrodendron, Genus Incertae Sedis, W. John Hayden

Biology Faculty Publications

This study of the vegetative anatomy of Picrodendron and some of its putative relatives has been undertaken in order better to understand its natural relationships. Despite the number of anatomical studies in the literature (Jadin, 1901; Solereder, 1908; Boas, 1913; Webber, 1936; Heimsch, 1942; Record & Hess, 1943; Metcalfe & Chalk, 1950), our information on the anatomy of Picrodendron is still incomplete· for example, nodal and petiolar anatomy has apparently never been described. Furthermore, with the exception of Record and Hess (1943), who discussed Picrodendron in a family by itself, other anatomists have compared Picrodendron only with members of Simaroubaceae, …

An Investigation Of The Nucleotide Cyclic 3'5' Adenosine Monophosphate In Young Hypocotyls Of Pisum Sativum L., Gary Marsh Hilton

Biological Sciences Theses & Dissertations

Concentrations of cAMP increased with time in pea hypocotyls assayed at 24 hour intervals over a period of four days. The highest concentration was 20.1 pmoles/mg protein which occurred in 96 hour hypocotyl tips. Ninety-six hour root bodies (dissected region between tip and embryo) achieved a concentration of 8.6 pmoles/mg. Concentrations of cAMP in embryos remained constant around one pmole/mg for three days and values doubled on the fourth day.

Hypocotyls, after germination for 72 hours, were dissected and incubated for various lengths of time in water and 3xl0^-8M IAA. Tips incubated for two hours showed a tenfold …

Bulletin 4002 - Trickle Irrigation For Farms, K Cole

Bulletins 4000 -

The continued demand for, and use of trickle irrigation is proof of the inherent potential and performance of this form of irrigation.

Originally it was used in glasshouses and nurseries but it is now widely adapted to orchards, vegetable and other horticultural small crops and home gardens.

Although research is being actively pursued in the design and use of trickle irrigation it is now beyond the experimental stage as a technique and is an accepted and proven technique of watering many types of crop.

The Cork Oak, S R J Newton

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

The oak or Querus genus embraces about 450 species which are generally restricted to the cool temperate regions of the Northern Hemisphere. Commercial cork is the over-abundant suberous tissue or bark from two rather unique members of the Querus genus, namely Q. suber and Q. occidentalis.

A lthough Western Australia has a most suitable climate for growing cork trees the potential of a local cork growing industry is severely limited.

Progress In The Nursery Industry, W J. Heggers

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

The demand for ornamental plants in Western Australia is sat an unprecedented level, making the nursery industry a relatively prosperous branch of horticulture.

One reason for the continued demand for nursery lines is probably that people are concerned about the environment - "green survival", as it is often refered to in promotional literature.

In rural areas, farmers are becoming increasingly aware of the value of planting windbreaks, shade and ornamental trees, while mining companies and the Forests Department are actively engaged in re-afforestation.

As a result the nursery industry is in a healthy situation and can continue to develop in …

Virus Diseases In Agriculture, George Mclean

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

Viruses are extremely small particles which can only be seen with an electron microscope. A virus is present in a diseased plant as huge numbers of tiny particles within the cells of the plant. Viruses which are infectious can cause disease, and reproduce only inside the cells of a living plant.

Many insects transmit plant virus diseases—aphids, leafhoppers, mealy bugs, thrips and beetles. Generally a virus is spread by only one of these groups of insects.

The Western Australian Department of Agriculture is expanding the diagnostic service for the identification of plant viruses.

The Banana Industry At Carnarvon, John Roger Burt

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

In viewing the semi-arid conditions of the West Gascoyne, visitors are surprised to see a thriving banana industry at the mouth of the Gascoyne River, 930 kilometres north of Perth. The natural vegetation in the plantation area consists mainly of stunted gums, low acacia scrub and salt bush.

Despite the adverse climatic conditions, the average yields of Carnarvon bananas are double those of banana areas in other states.

Promising Results With Pineapples At Carnarvon, Department Of Agriculture, Western Australia

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

Pineapples were investigated commercially in Carnarvon in the early 1930's but drought, sunscorch, alkaline soils and problems with transport and marketing caused the infant industry to collapse in 1936.

Recently however, trials at Gascoyne Research Station have shown that pineapples can produce good yields of high quality fruit in the area.

The trials have been aimed at establishing the viability of pineapple production at Carnarvon and have been carried out by officers of the Horticulture Division.

Lysimetric Calibration Of The Bowen Ratio-Energy Balance Method For Evapotranspiration Estimation In The Central Great Plains, Blaine L. Blad, Norman J. Rosenberg

Department of Agronomy and Horticulture: Faculty Publications

Most reports show good agreement between evapotranspiration (ET) rates estimated by Bowen Ratio-Energy Balance (BREB) method and rates measured with lysimeters, although underestimation by the BREB model has occasionally been reported. This study was conducted to evaluate the performance of the BREB technique in the climatic conditions characteristic of the central Great Plains, a region where a significant proportion of the energy consumed by evapotranspiration is supplied from advected sensible heat.

Agreement between the BREB method and lysimetric measurements of ET is good during non-advective periods but during advective periods the BREB model underestimates ET by about 20%. Data collected …

Penstemon In Your Garden, R. D. Uhlinger, G. Viehmeyer

Nebraska Agricultural Experiment Station: Historical Circulars

A new race of hardy perennials is beginning to appear in American gardens. These are the penstemons, a genus of plants closely related to the familiar snapdragon, which may become important ornamentals as they be come better known to gardeners. The purpose of this bulletin is to show the possibility of the genus as an ornamental and to suggest species and species hybrids of possible value to Great Plains gardeners; to provide information about propagation and culture; and to encourage gardeners to engage in penstemon breeding as an avocation.

Cause And Control Of A Common Market Disease Of Lettuce, William Palmore

Masters Theses & Specialist Projects

Head lettuce, Lactuta sativa var. capitata, is susceptible to a number of economically important diseases, the most frequent being russet spot, rib discoloration, and vascular browning (28), which have been shown by Ceponis and Friedman (7) to be caused by Pseudomonas marginalis. Pseudomonads are common plant pathogens and cause such diseases as halo blight in beans (20), bacterial blight in soybeans (20), and bacterial wilt of the bird-of-paradise (27) and tobacco (24).

Plants that develop symptoms similar to russet of lettuce are oats, infected by Pseudomonas cichorii, and tobacco infected with Pseudomonas tobaci (34). In general, russet symptoms …

Sturt Pea Hosts Collar Rot Fungus, M D. Marcley

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

Evidence that Western Australia's Sturt Pea can be attacked by collar rot fungus suggests a reason for the occurrence of collar rot in places where the fungus should not survive.

At Carnarvon for instance, in spite of the hot, dry conditions, the collar rot fungus has been found on eggplants and Tuart trees.

Infection of fruit and foliage by brown rot fungi (Phytophthora spp.) occurs after opening rains in autumn. It can continue during periods of wet weather until spring.

Powdery Mildew Of Apples, Department Of Agriculture, Western Australia

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

Powdery mildew (Podosphaera leucotricha) markedly affects the growth and vigour of susceptible apple varieties, particularly Jonathan and Cleopatra.

The fungus survives the winter as mycelial threads in dormant buds on spurs and laterals infected the previous season. At bud-burst the mycelium grows onto the developing leaves and blossom clusters to form white patches.

Spores produced on these patches are spread by the wind onto the healthy growth.
