High interest in ornamental plants as an element of landscaping has been actively going on recent years. In urban green construction, it is increasingly possible to meet not native local species, but introduced plants, which urbanized environments are many cases more stable and durable. For several years, we have studying the selection root formation stimulants, well their necessary concentrati...

Responses of American arborvitae (Thuja occidentalis), common yew (Taxus x media) and juniper (Juniperus communis) to enhanced UV-B irradiance were studied. Control plants were grown without UV treatment, but at identical PhaR and temperature regimes. Visual symptoms of the ultraviolet effect noted on Thuja shoots as brown/red discolouration were correlated with the accumulation of phenolic com...

UNLABELLED PREMISE OF THE STUDY Sixteen novel, polymorphic, multiplexed microsatellite loci were developed for eastern white cedar (Thuja occidentalis) using simple sequence repeat (SSR)-enriched shotgun pyrosequencing. • METHODS AND RESULTS Sixteen loci were tested on a panel of 24 individuals from different populations. The number of observed alleles ranged from four to 22. Four sets of ...

An improved method of counting acoustic emission (AE) events from water-stressed stems of cedar (Thuja occidentalis L.) is presented. Amplified AEs are analyzed on a real time basis by a microcomputer. The instrumentation counts AE events in a fashion nearly analogous to scintillation counting of radioactive materials.The technique was applied to measuring ultrasonic AEs from the stems of cedar...
