The research was carried out in the field at the Central experimental base of the Federal Williams Research Center. The object of research was 13 samples of timothy-grass. Samples were sown according to the scheme of a standard collection nursery. All studies and observations were carried out on the herbage of the 2nd and 3rd year of life. Statistical processing of the research results indicates a low level of variation. The sample № 414 stood out high content of raw protein and raw fat. Two significant correlations were found (between the content of phosphorus and potassium, as well as between crude fiber and crude ash). Analysis of remoteness and kinship between samples showed the presence of 5 clusters (genetically different quality groups), which can be used for breeding for combinational ability and fixing of breeding-valuable features and properties.

Thaw Water

SynopsisPlants are killed by prolonged ice encasement at slightly subzero temperatures and under these anoxic conditions a number of metabolites are accumulated. Timothy grass plants encased in ice at −2°C can survive these conditions for many weeks and accumulate mainly CO2 and ethanol and lower levels of malate, oxalate, citrate, fumarate and pyruvate. While the accumulation of most of the metabolites increases towards the end of the encasement period the amount of malate decreases, indicating utilisation. Late in the encasement period lactate, butyrate, and traces of malonate, formate and tartarate were detected which might be of bacterial origin. The bacteria most commonly isolated from ice-encased plants is Pseudomonas fluorescens (Trevisan) which in most cases is saprophytic. All of the above-mentioned metabolites were also detected from thaw water in the field after long duration of ice encasement, butyrate attaining the highest concentration.

The research was carried out in the field at the Central experimental base of the Federal Williams Re¬search Center. The object of research was 12 samples of wild-growing meadow timothy grass. Samples were sown according to the scheme of a standard collection nursery. All studies and observations were carried out on the herbage of the 2nd and 3rd year of life. Statistical processing of results of researches of meadow timothy indicates a low level of variation in the main morphological and physiological characte¬ristics. Only by the number of vegetative shoots have the coefficient of variation reach 35.8%. Samples 416 and 419 were distinguished by precocity, samples 406 and 419 by the height of plants during flower¬ing, sample 412 by the number of generative shoots, and sample 412 by the yield of air-dry mass. Sam¬ples 409 and 414 were distinguished by the length of the sultan, and the weight of seeds — 414 and 415. Nine reliable correlations were found at the significance level 05 and 01. However, all of them are related to the yield of the number of generative and vegetative shoots. Using the binomial equation, the experi¬mentally obtained variability of dry mass yield from the number of generative and vegetative shoots by 93.1% is described. The optimal productivity of meadow timothy grass stand for generative shoots in the area of 550–600 shoots, and vegetative ones — in the area of 320–350 shoots per square meter. Analysis of remoteness and kinship between samples showed the presence of 2 clusters (genetically different quality groups), which can be used for combinational ability selection and fixing of selection-valuable features and properties.

Fertilizer P was applied annually (0, 15, 29 and 44 kg P ha−1 yr−1) for 26 yr to an acidic loam cropped to timothy (Phleum pratense L.). Some fertilizer P was translocated into the 30- to 45-cm depth of soil when 15 kg P ha−1 yr−1 was applied and into the 45- to 60-cm depth when 44 kg P ha−1 yr−1 was applied. The amount of P translocated increased with increasing rates of applied P. Key words: Fertilizer, phosphorus, leaching, translocation, movement
