This paper presents the results of the analysis of 10 years of information 1957-1966 on three phases-- begin, peak and end bloom-- of the purple common lilac (Syringa vulgaris L.) using data recorded at approximately 1,000 locations throughout the Western Region of the United States. The pattern of geographical advance of the various bloom phases is determined by both a manual mapping procedure developed by the author and by standard statistical methods. Manually drawn isophanes for the various elevations for begin bloom phase are based entirely upon the first 5 years of record, 1957-1961. A Zones of Adjustment map to convert the 5-year equal level maps to the 10-year 1957-1966 normal is also manually drawn. Statistical analyses to ascertain the geographical pattern of advance were made for begin bloom phase for the 5-year period and for all three bloom phases for the 10-year period. Both the manual and statistical analyses indicate a very definite pattern of geographical advance of begin bloom phase of the lilac which is characterized by the Early Ridge. Statistical analyses of all three phases indicate a parallel geographical advance of the three phases with average regional time displacement of about 10 days from begin to peak bloom and 10 days between peak and end bloom. Only the eastern third of the Western Region corresponds closely with Hopkins' Bioclimatic Law. A measure of temporal variation of dates of bloom for each of all three phases indicate a parallel geographical advance of the three phases with average regional time displacement of about 10 days from begin to peak bloom and 10 days between peak and end bloom. Only the eastern third of the Western Region corresponds closely with Hopkins' Bioclimatic Law. A measure of temporal variation of dates of bloom for each of the three phases was determined by computing standard deviations for every station having at least 5 years of record. A map was drawn showing the temporal variability of begin bloom phase throughout the Western Region. Medians of standard deviations for stat ions within each state were also determined. Large differences in standard deviation prevail throughout the region with a general tendency for variability to be highest in the southeastern part of the region and lowest in northeastern areas. A comparison is made between the normal dates of occurrence of bloom phases and temperature data throughout the Western Region. This is achieved by comparing isophanal and isothermal charts and by statistical analysis of data at 360 stations where both phenological and temperature records are available. Comparison of isophanal patterns of equal-level isophanal maps and isotherms at given elevations ( or pressure lvels) on given dates indicate very similar patterns; both are characterized by the Early Ridge. Statistical Analyses of mean begin bloom dates and monthly mean maximum and minimum temperatures indicate that about 90 percent of the variance of bloom dates can be accounted for by maximum and minimum temperature measurements.

My thesis tested efect of mycorrhizal fungy on herbal cutting. There was two terms propagation of four species. Syringa meyeri 'Palibin', Forsythia x intermedia 'Maluch', Cornus alba and Berberis thunbergii 'Rose Glow'. Experiment had two variantion and three repeats. Plants couldn't be nursed. Most of the results are inconclusive, because of the high losses. For species of Syringa meyeri 'Palibin' was demonstrated high influence of mycorrhizal fungi. There were also differences in terms. Overlay film had a positive impact only on Cornus alba. For species Cornus alba and Forsythia x intermedia 'Maluch' second term was more successful. When propagation of mycorrhiza has high potential.

The aim of my thesis was experimental prove of the influence of mycorrhizal product in the production of nursery propagation by herbaceous cuttings. On trial were selected three plant species, Deutzia gracilis 'Nikko', Forsythia x intermedia 'Maluch' and Syringa meyeri 'Palibin'. The experiment was based on two dates, and was conducted of the Institution of cultivation and reproducing of garden plants of Garden faculty of the Mendel University in Lednice. Evaluation was carried out in two variants, after three repetitions. The first variant was a control without mycorrhizal product, the second was supplemented with mycorrhizal fungi. It evaluated the number of roots, number of branched roots, cuttings and mortality rate of colonization. Differences in rooting and branching roots were among species, and between terms. The positive effect of mycorrhizal fungi was at Deutzia gracilis 'Nikko' and Forsythia x intermedia 'Maluch'.

This thesis was written up at the Department of Breeding and Propagation of Horticultural Plants under Faculty of Horticulture Mendel University in Lednice. The thesis deals with rooting of woody species of chosen kinds of Ornamental wood. The experiment was performed for Berberis thunbergii ´Rose Glow´ and for Syringa meyeri ´Palibin´ in two terms (16.6.2016 and 1.8.2016) and in four variants. The fourth variant was for control only.
