    Notes: General conclusions are drawn from the study of spaced plants of 29 varieties of Lolium perenne, 23 of Dactylis glomerata and 26 of Phleum pratense.Highly significant correlations are established in each species between date of ear emergence and each of the characters, growth habit, stem length and aftermath shooting.The classification of varieties proposed on the basis of the earlier trials by the spaced-plant method is reviewed and revision in certain respects is proposed.For each species the varieties are listed in order of ear emergence. New varieties tend to fill the gaps in such a sequence and in time there may be continuity from the earliest to the latest varieties. In such circumstances classification into clearly delineated groups would become impossible.

    RESPONSE OF GRASSLAND TO NITROGENOUS FERTILIZER IN THE WEST OF ENGLAND (1964)

    Notes: Extensive replicated plot experiments were carried out at Henley Manor Farm from 1956–1961 to obtain accurate measurements of herbage production and response to nitrogenous fertilizers under West of England conditions. 356 plots were used; use of the herbage by both cutting and grazing was studied. The principal results are: Grass/ clover swards (containing approx. 35% clover) grown without nitrogenous fertilizer averaged 75 cwt dry matter per acre per annum. Application of nitro-chalk to initially grass/clover swards reduced the clover content of the herbage. About 133 lb N/annum was required by an all-grass sward to equal the production of a grass/clover sward without N. Attempts to increase production of grass/clover swards by using N for early growth and relying on clover for mid-season growth were unsuccessful in 2 out of 3 years. Swards (initially grass/clover) gave significant increases in total dry-matter production from regular use of the lowest level of N (26.0 or 34.7 lb N/acre/cut or graze) in 44 out of 49 cases. Extremely high yields were obtained from the heaviest use of N (104.2 lb N/acre/silage cut). 52.1 lb N/acre/cut or graze was the optimum rate of application on ail-grass and grass/clover swards. Up to about 350 lb N/acre/annum the dosage-response curve was very nearly straight for all-grass and grass/clover swards. On the grazed plots herbage left ungrazed amounted on average to only 6% of the total. The health of all stock on the high nitrogen plots (as well as all others) was excellent.

    Notes: Seeds of four legumes and four grasses were germinated in the presence of aqueous extracts of the same species, using distilled water as a check. Measurements were taken to determine the effect of the extracts on germination, root growth and shoot growth. Based on the number of significant reactions to the extracts, the species may be classified in the following order of decreasing inhibition: alfalfa, birdsfoot trefoil, Ladino clover, red clover, reed canary grass, brome grass, timothy and orchard grass. Conversely, alfalfa and timothy were the species least affected by the extracts while reed canary grass was the most susceptible. Other species were in an intermediate range. With the exception of alfalfa, extracts of aerial portions of the plants had greater inhibitory effects than root extracts.

    Recharge Distribution Determined by Analog Model (1966)
    Oxford, UK : Blackwell Publishing Ltd
    Ground water 4 (1966), S. 0

    Notes: A two-dimensional, passive element electric analog model was used to determine the spatial distribution of natural ground-water recharge in the Santa Cruz River basin of southern Arizona. Existing records were used to draw a ground-water level contour map of the area in its undeveloped condition. The model was made to duplicate these contours by varying inputs from known locations of recharge. Recharge distribution as determined by the model was consistent with previous estimates, but no direct correlation was found with the contributing drainage area.

    The Effect of pH-Temperature Treatments on the Calcium Accumulating Ability of Purified Sarcoplasmic Reticulum (1969)

    Notes: SUMMARY: Pig sarcoplasmic reticulum fragments obtained from the longissimus dorsi muscle at 0- and 24-hours post-mortem were purified by salt extraction and density gradient centrifugation. The calcium uptake activity of 0-hour purified preparations was more than 20-fold higher than that from 24-hr old muscles, but there was no significant difference between fractions for calcium activated ATPase activities. When observed electron microscopically after negative staining, the ultrastructures of the 0. and 24-hour membrane fragments were found to be essentially identical. Incubation of isolated sacroplasmic reticulum fragments at pH 7.2 and 37°C or pH 5.6 and 0°C caused negligible inhibitoin of their calcium accumulating ability. However, treatment at pH 5.6 and 37°C for 1 hr almost completely abolished the sarcoplasmic reticulum calcium uptake. Thus it appears that low muscle pH and high temperature may be responsible for the inactivation of the calcium accumulating ability of the sarcoplasmic reticulum that occurs in situ.

    Post-Mortem Changes in Subcellular Fractions from Normal and Pale, Soft, Exudative Porcine Muscle. 1. Calcium Accumulation and Adenosine Triphosphatase Activities (1969)

    Notes: SUMMARY– Myofibrillar, mitochondrial, heavy sarcoplasmic reticulum and light sarcoplasmic reticulum fractions were isolated by differential centrifugation of homogenates from normal and pale, soft, exudative (PSE) porcine muscle at various times post-mortem. Calcium uptake was measured using a solution containing45Ca++. The oxalate-stimulated calcium accumulating ability of the subcellular fractions declined 5-10 fold between 0 and 24 hr post-mortem. The major portion of this decline occurred in the first hour after death in fractions from PSE muscle but was more gradual in the normal fractions. The ATPase activities of normal and PSE fractions obtained at death did not differ significantly. These activities increased with time post-mortem in most normal fractions but decreased in those from PSE muscle. The subcellular site of ATP hydrolysis post-mortem was discussed. The results obtained point to the potential importance of the relaxing, factor in muscle post-mortem.

    A Quantitative and Morphological Study of Bovine Longissimus Fat Cells (1968)

    Notes: SUMMARY— A quantitative and morphological study was made of bovine fat cells from three marbling groups of longissimus muscle. Tracings on acetate paper were made of the visual marbling depots and the area measured at three positions with an ocular grid for both size and distribution of fat cells. Comparisons were also made of subcutaneous, intermuscular and intramuscular fat cell size. Intrafiber lipid accumulation was observed and the average number of red fibers per bundle determined. These results indicate that traceable intramuscular fat is not a good measure of total intramuscular fat. There did not appear to be a consistent medial, central and lateral marbling pattern among the three marbling groups; however, significant differences were apparent within groups. Fat cell size increased with increases in cell mass, marbling and total chemical fat of the muscle.Fat cells accumulated and grew in close proximity to portions of the circulatory system. Lipid deposits adjacent to the muscle contained larger fat cells than was evident in the extrafascicular spaces within the muscle. Intrafiber lipid was readily apparent in approximately 35% of the muscle fibers and probably represented either mitochondria or triglyceride. The interrelationship of subjective marbling scores, chemically determined fat, fat cell size, fat cell distribution and intrafiber lipid characteristics are complex and require complete investigation before the association of muscle fat and meat quality can be resolved.

    Prediction of the Time Course of Rigor Mortis Through Response of Muscle Tissue to Electrical Stimulation (1966)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 31 (1966), S. 0

    Notes: A technique based on muscle response to electrical stimulation was shown to be useful in predicting, within 10 min of exsanguination, the time course of rigor mortis, rate of postmortem glycolysis, and ultimate color-morphology rating. The response of an excised muscle to electrical stimulation was highly associated with post-mortem muscle properties. The excitability threshold (lowest voltage at which contraction resulted) was found to be high in muscles which had a short time course of rigor mortis, fast postmortem glycolysis, and pale, soft, and exudative (PSE) ultimate gross morphology; and low in muscles with a long time course of rigor mortis, slow post-mortem glycolysis, and ultimately normal color-morphology. Strength of contraction (at 5, 10, 25, and 50 volts) was observed to be highest in muscles which exhibited long rigor, slow glycolytic rate, and normal color-morphology. The duration of contractility (maintained under repeated stimulation at 2 cycles/see) was also noted to be longer in this type of muscle. Multiple-regression analysis indicated that up to 87% of the variability in color-morphology rating could be predicted by combining the various parameters of muscle response to electrical stimulation. Breed differences were observed which must be taken into account when using prediction equations.
