Abstract

The Simple Sequence Repeats (SSR) method of DNA analyses was used to clonal identification of trees in a model wild cherry (Prunus avium L.) seed orchard. Total genomic DNA was extracted by DNA Plant Mini Kit (QIAGEN) from buds taken from 91 sampled trees of the seed orchard. Samples were screened using selected ten polymorphic nuclear microsatellite markers. Measuring of the size of amplification products was carried out using the genetic analyser Applied Biosystems 3500. The obtained data were analysed by statistical programs CERVUS, GenAlEx 6.501 and Micro-Checker. There were detected 65 different alleles at 10 loci in the 91 wild cherry individuals from seed orchard. By applying of the 10 suitable markers to the 18 clones from model seed orchard we obtained multilocus genotypes (MLG). The obtained results illustrate the utility of the microsatellite loci for assessing spatial patterns of genetic diversity and for individual genotypes identification. Declared clone affiliation was confirmed in 94% of sampled trees. The identified genetic loci were verified as highly polymorphic and could be further used for clonal identification of wild cherry trees. [ABSTRACT FROM AUTHOR]

Abstract

Wild cherry produces very valuable wood that can increase economic benefits in forest management. In order to achieve quality cherries, it is necessary to carry out the pruning, which gradually achieves straight, long and knotless trunks. The aim of the work was to evaluate the reaction of cherries to different ways of pruning. The research took place in four young stands located at the TFE Křtiny. The results confirm that the pruning has a negative effect on the diameter increment. The more powerful the crown reduction, the more increment decreases. The effect of pruning on the height increment did not prove certainly. A practical recommendation is to realise a milder or selective pruning method that does not reduce significantly the diameter increment. Wild cherries should be pruned in time, repeatedly after two to three years, when the branches are not too thick, and a rapid healing of the cutting wounds can be expected. In addition, it is necessary to grow cherry trees with nurse species, which protect their trunks from the sunlight causing secondary shoots.
