Lupin Split Seed : A Disorder Of Seed Production In Sweet, Narrow-Leafed Lupins, M W. Perry, J. W. Gartrell Jan 1976

Lupin Split Seed : A Disorder Of Seed Production In Sweet, Narrow-Leafed Lupins, M W. Perry, J. W. Gartrell

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

Commercial seed production from narrow-leafed lupins (Lupinus angustifolius L.) began in Western Australia in 1967, based on the newly-bred low alkaloid cultivar Uniwhite. The release of improved cultivars has led to the crop's wide acceptance and more than 100 000 ha were sown to sweet lupins in 1975.

With the greater area and wider range of soil types devoted to lupins, a developmental abnormality of the seeds, which became known as "split seed", was observed in some situations.

1976 Sunflower-Safflower Irrigated Variety Trial 1976-1977, G J. Parlevliet Jan 1976

1976 Sunflower-Safflower Irrigated Variety Trial 1976-1977, G J. Parlevliet

Experimental Summaries - Plant Research

In 1975/76 two varieties of sunflower, Hysun 10 and Hysun 20, as well as Safflower (Gila) were grown in a large alternative crop demonstration. Results were sufficiently good to warrant more and closer examination. This led to the present variety trial using varieties suggested by Mr. M. Poole. The aim was to evaluate six sunflower varieties and one safflower. The work was carried out in the light of reduced profitability of peas, beans and some fruit crops. This results in a number of growers having irrigation water and equipment under-employed. Other farmers are after a crop which will give them …


The Mediterranean White Lupin, John Sylvester Gladstones Jan 1976

The Mediterranean White Lupin, John Sylvester Gladstones

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

"If you want to bring in a good lupin harvest, thrash your wife soundly before you go out sowing in the field". Old Syrian Proverb.

Lupin breeder Dr. John Gladstones does not beat his wife as recommended in the Syrian proverb above. Nor is he known to use ground up lupin seeds for the diverse cosmetic and medicinal purposes recommended in ancient Roman and other texts on lupins.

But his modern work on lupin breeding and development has undoubtedly been influenced by his detailed study of such writings.

In this article he discusses the history of the Mediterranean white lupin …

Purine-Thiamine Anabolism During Cellular Morphogenesis In Myxococcus Xanthus, Wen-Cherng Tsai Jan 1976

Purine-Thiamine Anabolism During Cellular Morphogenesis In Myxococcus Xanthus, Wen-Cherng Tsai

Electronic Theses and Dissertations

Purine-thiamine anabolism during cellular morphogenesis in Myxococcus xanthus was investigated. One of the approaches was to test vegetative and myxospore (2.5 h and 8 h) extracts of M. xanthus CW-2 for their ability to synthesize the second de novo intermediate, 5'-phosphoribosylglycinamide, from beginning precursors either by way of phosphoribosyl-pyrophosphate amidotransferase (EC 2.4.2.14) or ribose-5-phosphate aminotransferase. Results indicate the presence of both the amido- and aminotransferases in both types of extracts, and both enzymes appear to be present at about the same level (per milligram of protein) in vegetative cells, myxospores (2.5 h and 8 h), and in a bacterial prototype, …

Reevaluation Of Common Wheats From The Usda World Wheat Collection For Protein And Lysine Content, K. P. Vogel, V. A. Johnson, P. J. Mattern Nov 1975

Reevaluation Of Common Wheats From The Usda World Wheat Collection For Protein And Lysine Content, K. P. Vogel, V. A. Johnson, P. J. Mattern

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The protein and lysine content of wheat can be altered by breeding only if genetic variability exists for these traits. Lysine is a nutritionally limiting amino acid in wheat protein. Protein and lysine analyses of the common wheats of the USDA World Wheat Collection indicated that variability does exist for these traits. Some of the variability for protein and lysine among wheats of the World Collection may not be genetic in origin, because all the 12,000 wheats analyzed were not grown in the same environment. The purpose of this study was to reevaluate selected lines from the World Wheat Collection …


Ultrastructural Investigations Of The Host-Parasite Interface Of Pumpkin Cotyledons And The Fungus Sclerotinia Sclerotiorum, Mark Edward Richtsteig Aug 1975

Ultrastructural Investigations Of The Host-Parasite Interface Of Pumpkin Cotyledons And The Fungus Sclerotinia Sclerotiorum, Mark Edward Richtsteig

Theses and Dissertations

Pumkin seedlings (Cucurbita maxima) were inoculated with the fungus Sclerotinia sclerotiorum (Lib.) de Bary. Center regions of non-infected and infected cotyledons of various lengths were cut into 1 x 2 mm strips and processed for ultrastructural investigations. Complementary portions of opposing non-infected cotyledons were also processed as control tissue, and contained fewer storage products in cells than cotyledons of comparable size from non-infected plants. Young non-infected cells contained distinct lipid bodies, protein bodies and electron dense inlusions which were translocated out of older cells by abundant plasmodesmata. Initally, infected cells became plasmolyzed, followed by breakdown of the cytoplasm. Host cells …

Nutritional Quality And Herbage Production Of Intermediate Wheatgrass (Agropyron Intermedium [Host] Beauv.) When Infested With Black Grass Bugs (Labops Hesperius Uhler), Alan M. Gray May 1975

Nutritional Quality And Herbage Production Of Intermediate Wheatgrass (Agropyron Intermedium [Host] Beauv.) When Infested With Black Grass Bugs (Labops Hesperius Uhler), Alan M. Gray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two intermediate wheatgrass seedings with different levels of grass bug infestation were evaluated for herbage production, seedhead production, percent dry matter, crude protein, and cell contents. Study sites were located at different elevations on mountain summer ranges in northern (Site I) and central (Site II) Utah. Study plots at Site I and Site II were infested with 113 and 210 bugs per sweep, respectively. Herbage production appeared to be reduced in early spring on the site with the higher infestation; however, no effect on season-long herbage production could be detected on either site. Seedhead production on infested plots was reduced …


The Effect Of Environment And Cultural Practices On The Cold Hardiness Of Peach Wood, Larry A. Sagers May 1975

The Effect Of Environment And Cultural Practices On The Cold Hardiness Of Peach Wood, Larry A. Sagers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Studies were conducted to better understand the effect of temperature, photoperiod, cultural practices, and growth regulators on the hardening and dehardening of peach tree wood.

Greenhouses were constructed to control temperatures to which peach trees were exposed. It was noted that hardening and dehardening usually followed the temperature fluctuation fairly closely. However, trees exposed to temperatures above 60 F (15.6 C) became hardy to 0 F (-17.8 C).

A photoperiodic response in regard to an increase or decrease in hardiness was not definitely observed in peach wood. Extended photoperiod did not produce any significant effect on hardiness. Defoliation, bloom date, …


The Use Of Foliar Applied Zinc Compounds In Correcting Zinc Deficiency In Fruit Crops, Lynn F. Hall May 1975

The Use Of Foliar Applied Zinc Compounds In Correcting Zinc Deficiency In Fruit Crops, Lynn F. Hall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effectiveness of two chelated zinc compounds in correcting zinc deficiencies was studied. Soil and foliar treatments were made to study possible residual zinc carry-over from one season to the next. Foliar treatments at various rates were applied to raise plant tissue zinc levels above deficiency levels. It was found that none of the treatments studied resulted in any substantial carry-over of zinc to the following year. All of the foliar zinc treatments resulted in an increase in leaf zinc content in all of the varieties of fruit studied. The level of zinc in the treated trees increased in proportion …


An Assay Chamber For Quantitative Analysis Of Nitrogen Fixation Using Intact Plants, Thomas Adrie Leslie Apr 1975

An Assay Chamber For Quantitative Analysis Of Nitrogen Fixation Using Intact Plants, Thomas Adrie Leslie

Theses and Dissertations

A unique assay system for quantitative analysis of biological nitrogen fixation by intact plants has been constructed and successfully tested. With the system, it has been possible to detect acetylene reduction by intact legumes in situ under laboratory conditions. This assay method is designed to approximate field conditions and in spite of possible procedural errors in sampling, background noise of the gas chromatograph and ethylene contamination of the acetylene gas used in the assay, this method is sensitive ·enough to detect as little as 1 ppm enrichment of ethylene gas as a result of acetylene reduction by intact soybean plants. …


Summary Of Trial Results - 1974, N R. Mckeown Feb 1975

Summary Of Trial Results - 1974, N R. Mckeown

Experimental Summaries - Plant Research

Observations and measurements were made on 10 grazing trials and 11 small-plot legume species trials in 1974. Three of the grazing trials were under crop, two of them concluding low oestrogen species trials which had been grazed since 1969, and one of them, 68M023, West Moora, as an interval between pasture phases. The small-plot trials dated from 1970 or later and on most of them half of each plot could be grazed by sheep and half was protected. These trials have continued to supply useful information on the suitabiliy of cultivars to soil and climate and will be the subject …


Breeding Better Rape And Lineseed For Western Australia, N N. Roy, J. Reeves Jan 1975

Breeding Better Rape And Lineseed For Western Australia, N N. Roy, J. Reeves

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

Rapeseed and linseed—the main oil seed crops grown in the south-west of Western Australia—have both been beset by problems which have limited farmers' interest in them.

Rapeseed was first grown commercially in 1970, when wheat quotas and low prices for other cereals forced farmers to seek alternative cash crops. The area sown to rapeseed increased rapidly, but disastrous outbreaks of the disease blackleg caused rapid decline, and little rapeseed is now sown.

Linseed has been grown in W.A. for more than 30 years. Linseed rust proved disastrous but was overcome by the introduction and breedbreeding of rust-resistant varieties. In recent …


Lupinosis And Rates Of Stocking Of Lupin Stubbles, K P. Croker, J. G. Allen, C. R. Lester, R. B. Guthrie Jan 1975

Lupinosis And Rates Of Stocking Of Lupin Stubbles, K P. Croker, J. G. Allen, C. R. Lester, R. B. Guthrie

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

Lupin stubbles provide valuable summer sheep feed but under some conditions the fungus Phomopsis rossiana (for which lupins are the host plant) produces a toxin that causes lupinosis. Results from research at Badaingarra Research Station over the 1973-74 and 1974- 75 summers have shown that sheep liver damage associated with lupin stubble grazing is likely to be more severe at high than low stocking rates.

Carbohydrate And Organic Nitrogen Concentrations Within Range Grass Parts At Maturity, L. J. Perry Jr., Lowell E. Moser Jul 1974

Carbohydrate And Organic Nitrogen Concentrations Within Range Grass Parts At Maturity, L. J. Perry Jr., Lowell E. Moser

Department of Agronomy and Horticulture: Faculty Publications

Total nonstructural carbohydrate (TNC) levels were significantly different among eight range grasses at maturity. Roots, rhizomes, and stem bases (storage organs), differed significantly in percentage TNC within rhizomatous and bunch-type (non-rhizomatous) grasses. Percent organic nitrogen differed significantly among grasses and storage organs but not to the same extent as with TNC. We of nonstructural polysaccharide accumulated (Smith, 1968; suggest that TNC concentrations of storage organs must be determined for each grass before sampling for TNC levels, in Grasses of subtropical order to locate storage organs with greatest TNC concentration.


Nutrition Of Sheep Grazing Foothill Big Game Range In Spring, Kurt J. Kotter May 1974

Nutrition Of Sheep Grazing Foothill Big Game Range In Spring, Kurt J. Kotter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sheep with esophageal fistulas were used to determine the daily intake, nutritive content and digestibility of forage at three periods and two stocking intensities during the spring of 1972 on a typical foothill range in northern Utah.

Heavy grazing under a season-long regime did not influence the concentrations of dietary chemical components when compared to moderate grazing; however, it did depress the digestibility of cellulose and organic matter. There was a significant decline in the dietary chemical components due to forage maturation. Digestibility of organic matter and cellulose were significantly higher in the early spring as compared to late spring. …


Aspects Of Salt Tolerance Of Salicornia Pacifica Standl. Var. Utahensis (Tidestrom) Munz, Dennis J. Hansen Apr 1974

Aspects Of Salt Tolerance Of Salicornia Pacifica Standl. Var. Utahensis (Tidestrom) Munz, Dennis J. Hansen

Theses and Dissertations

Aspects of salt tolerance of Salicornia pacifica were investigated. Survival of this plant in a saline environment is due to many interacting factors. A soil pH of 7.5 to 8.0 +- 0.2 and a constant sub-surface soil moisture level of 25 to 35% are necessary for plant survival. A fluctuating lower soil moisture leevel and higher pH favor etablishment of Distichlis stricta. The ion content in S. pacifica remained constant despite increased moisture stress throughout the growing season due to accumulation of salts which were significantly higher in the surface soil layers than in the subsurface layers around the roots. …
