    Description / Table of Contents: Palaeohydrology is the study of changes in the waters of the Earth prior to continuous monitoring. Knowledge of these changes is important for the understanding of past and present environmental changes and of the form of the present-day environment. The evolution of the hydrological cycle in response to climatic change produces a chain of environmental and human consequences — factors that are becoming more relevant as climate change is predicted. Evidence of past environmental changes may be used to validate models with which to predict future change — thus the study of rates, mechanisms and processes of Late Quaternary hydrological changes is of critical importance. This volume is designed for all who are interested in the hydrological impacts of climatic change and the contribution that palaeohydrology can make to the study of these changes. It details recent achievements in this important field, and provides for prioritizing and guiding future studies.

    Notes: Attempts to increase European biodiversity by restoring rivers and floodplains are based on inadequate data on natural systems. This is particularly the case for NW European rivers because all catchments have been impacted by agriculture and river engineering. If river restoration is to have an ecological, as opposed to `cosmetic' design basis then baseline models are required. However, this poses three questions; (a) what is the natural river-floodplain state, (b) how can it be defined and modelled and (c) can this state be recreated today? The first two questions can only be addressed by using palaeohydrological and palaeoecological data. A second and equally vital consideration is the stability/instability of any restored system to change in external forcing factors (e.g. climate) and in this context it may not be realistic to expect baseline models to provide equilibrium solutions but instead to define process-form domains. Over the last two decades evidence has accumulated that the natural state of lowland rivers in much of NW Europe was multi rather than single thread-braided, anastomosing or anabranching. Until recently our knowledge of floodplain palaeoecology was generally derived from pollen diagrams, which have source-area of problems and lack of taxonomic specificity. The precision and breadth of palaeoecological reconstruction (including richness and structure) has been greatly increased by the use of multiple palaeo-indicators including macrofossils, diatoms and beetles. The dynamics of small to medium sized, low-energy, predeforestation floodplains were dominated by disturbance (windthrow, beavers, etc.) and large woody debris. In order to compare the hydrogeomorphological basis of floodplain ecology, both temporally and spatially, a simple index of fluvial complexity is presented. Palaeoecological and geomorphological investigations have the potential to provide in-depth models of the natural range of channel conditions and sensitivity to external change that can be used to provide a scientific basis for floodplain restoration. There is also the possibility that floodplain-channel restoration may be a valuable tool in the mitigation of future geomorphological change forced by climatic instability.

    Notes: Summary A survey was made of the sweetness and sourness of the fruits of apple cultivars. Measurements of the concentration of sugars and malic acid in ripe fruits were made and the variation between samples of a cultivar, between cultivars, between years and between cultivars and their tetraploid and colour sports was studied and showed a wide range of variation between cultivars but fairly constant values within cultivars. The study of a number of progenies shows that sweetness and sourness are inherited independently. Sweetness shows a quantitative pattern of inheritance and the progeny mean approximates the mid-parent value. Sourness is controlled by a single gene, with medium and high acidity being dominant to very low, superimposed on a quantitative pattern. The mean sugar and acid concentrations of a progeny and the approximate range of variation can be predicted from the sugar and acid concentrations found in the parents.

    Description / Table of Contents: Samenvatting Resistentie tegen meeldauw erft kwantitatief over; de invloed van ouders op de resistentie der nakomelingschappen is uiteenlopend. De gemiddelde relatieve resistentiewaarden van de nakomelingschappen van bepaalde rassen vertonen grote overeenkomst, onverschillig of deze het resultaat van zelfbevruchting of van kruising zijn. Aangetoond werd dat de resistentie van de nakomelingschappen correlatie vertoont met de resistentie van de ouders. Een statistische bewerking van de gegevens, waarbij de methoden van een onvolledige diallele kruising werden toegepast, maakte het mogelijk de invloed van elk der ouders op de meeldauwresistentie van de nakomelingschap te berekenen. De appelrassen Beauty of Bath en Lord Lambourne brachten de resistentie in de hoogste mate op hun nakomelingschap over. Merton Russet en Late Orange in de geringste mate. Deze methode van bewerking biedt de mogelijkheid de gemiddelde resistentie van de kruisingsnakomelingschappen te schatten indien volledige waarnemingen ontbreken.
    Notes: Abstract 1. Resistance to Apple Mildew (Podosphaera leucotricha) is shown to be inherited quantitatively and apple varieties vary in the resistance contribution which they pass on to their progeny. 2. The mean relative resistance values of progenies of given varieties correspond closely irrespective of whether they are the result of selfing or outcrossing. 3. It is shown that resistance in progenies is correlated with the resistance reactions of the parents. 4. A statistical analysis of the data, using methods applicable to an incomplete diallel cross, has enabled the contribution of each parent to resistance to mildew of its progenies to be calculated. Of the cultivated varieties, Beauty of Bath and Lord Lambourne gave the highest contributions and Merton Russet and Late Orange the lowest. This method of analysis allows the estimation of the mean resistance of the progenies of varietal crosses in the absence of complete observational records.

    Notes: Abstract We present a photometric investigation, using the VBLUW system, of the stellar content of Orion OB1. Physical parameters (logg, logT eff) for the stars are derived with the aid of model atmospheres. From these, visual extinctions, absolute magnitudes and distance moduli are derived. The distance moduli are used to determine membership for the stars in each of the subgroups and distances to the subgroups are calculated. The ages of the subgroups are derived through isochrone fitting and the IMF is derived for each subgroup. The energy deposited into the ISM through stellar winds and supernovae is calculated and compared to observed large scale features in the ISM around Orion OB1.

    Notes: Summary We examined the inheritance, heritability, and breeding behaviour of resistance to Septoria tritict in the spring wheat cultivars Seabreeze, Veranopolis, and IAS-20 in crosses to the susceptible Australian spring cultivar Gamenya. Resistance in Seabreeze was higher than that in Veranopolis and IAS-20. Inheritance of resistance in Seabreeze seems to be determined by at least three recessive genes. Resistance in Veranopolis and IAS-20 might be due to a single gene. Similarity of inheritance patterns and breeding behaviour of the resistance from Veranopolis and IAS-20 and the common ancestry of these two cultivars suggest that they may carry the same gene. Standard unit heritabilities of Septoria scores, as measured by correlation of F2 plant with F3 family mean data, were high (57–68%). Parent offspring genetic correlations confirmed previously reported associations between resistance and lateness and resistance and tall plant height, but correlations were not sufficiently high to be a major obstacle to selection. Resistance in Veranopolis and IAS-20 were easily recovered in first backcrosses while that in Sea breeze was more difficult to recover.

    Notes: Summary A population of 572 F2 derived F3 lines from six crosses were used to estimate parameters relevant to selection for resistance to Septoria nodorum of wheat. Lines were grown in disease free (fungicide sprayed) and inoculated microplots in 2 replications of a split-plot design in a single environment in 1977. Average yield reduction due to disease was approximately 50%; this was associated with an average septoria score of 50% on the flag leaf, an average septoria score of 42% on the head, and a reduction of 37% in seed weight. Low S. nodorum scores were correlated with late heading date, tall plant height, high grain yield, and high seed weight in diseased plots, and high seed weight % (seed weight in diseased plots expressed as a percentage of seed weight in fungicide sprayed plots). Restricted selection indexes were used to study the relative contributions of disease escape, true resistance, and tolerance to variability in grain yield in diseased plots, seed weight in diseased plots, and seed weight %. True resistance appeared to be the most important factor causing variation in grain yield in diseased plots and seed weight %. Tolerance and escape seemed to be more important for seed weight in diseased plots. Heritabilities of S. nodorum scores on the flag leaf and head were 63% and 52%, respectively. Leaf and head scores could be used most effectively as selection criteria to upgrade resistance in a population before harvest. Selection for high seed weight % slightly reduced yields in disease free plots, although yield in diseased plots and seed weight in diseased plots were increased. However, selection for increased yield or increased seed weight in diseased plots improved yield in disease free plots. It is suggested that direct selection for yield or seed weight in diseased plots is likely to achieve more desirable goals than selection for seed weight %.
