Evaluation of growth and physiological parameters in wild cherry progeny trial

Anotace:

The present diploma thesis deals with the evaluation of growth and physiological parameters in wild cherry progeny trial (Prunus avium L.). Wild cherry is one of the hardwood very sought in the timber industry market and whose importance from the ecological and economic point of view is very promising. The research aimed to obtain preliminary information on mortality, growth traits and basic physiological parameters from a progeny trial stand of wild Cherry at the the Czech military forest (VLS ČR, s.p.) located close to vicinity of Lišice (by Chlumec nad Cidlinou), in north-eastern part of Czech Republic. The height parameter was assessed for all the individuals as well as the Chlorophyll fluorescence performed using a portable Fluorometer FluorPen FP100max. Pedigree reconstruction were also evaluated from data collected one year before. Collected data relating to the height were analyzed in MS Excel to provide qualitative information about the experimental stand and basic statistic description. Heritability of the height and ChlF was done using ASReml program. Two distinct models were tested with the intention to compare they influence in heritability values for parameters considered, especially the height and the Fj parameters. A total of 455 individuals were analyzed for height and 369 for the chlorophyll fluorescence parameters. Relatively high mortality about 4,6 % was detected on the tested area. Regarding the height, the ASReml analysis detected a moderately high heritability (h^2) that was about 0.5621 and 0.5810 with approximate standard errors for 0.1506 and 0.1524 respectively for the first and the second model. As for the parameter Fj, heritability (h2) was 0.1110 with a standard error of 0.0888 for the first model and 0.1176 with a standard error of 0.0892. Comparison performed for the simple and mixed model with AsRmel software did not revealed significant differences.
