The present study was carried out on Paulownia tomentosa (6), Paulownia elongate (4), Paulownia fortunei (5) and Paulownia fortunei x tomentosa (1) origins at Kastamonu Forest Nursery. The seedling height growth (SH), root collar diameter (RCD), dry root percentage (DRP) and seedling percentage (SP) of one-year old seedlings of the origins were studied for comparing growth performance of the sp...

Paulownia is a fast-growing deciduous hardwood species native to China, which has high ecological and economic value. In an earlier study, we reported ploidy-dependent differences in Paulownia drought tolerance by the microscopic observations of the leaves. Autotetraploid Paulownia has a higher resistance to drought stress than their diploid relatives. In order to obtain genetic information on ...

Paulownia fortunei is a widely cultivated economic forest tree species that is susceptible to infection with phytoplasma, resulting in Paulownia witches' broom (PaWB) disease. Diseased P. fortunei is characterized by stunted growth, witches' broom, shortened internodes, and etiolated and smaller leaves. To understand the molecular mechanism of its pathogenesis, we applied isobaric tags for rela...

Phytoplasmas are mycoplasma-like pathogens of witches' broom disease, and are responsible for serious yield losses of Paulownia trees worldwide. The molecular mechanisms of disease development in Paulownia are of considerable interest, but still poorly understood. Here, we have applied transcriptome sequencing technology and a de novo assembly approach to analyze gene expression profiles in Pau...

The use of fast growing trees could be an alternative in trace element contaminated soils to stabilize these elements and improve soil quality. In this study we investigate the effect of Paulownia fortunei growth on trace element contaminated soils amended with two organic composts under semi-field conditions for a period of 18 months. The experiment was carried out in containers filled with tr...

P. fortunei was imported into Iran from China and was planted at different spacings in the forest of the north of Iran, for wood production. In this research, physical, chemical, mechanical properties and morphological characteristics of Iranian cultivated paulownia (Paulownia fortunei L.) wood were investigated. Paulownia has acceptable Runkel, flexibility and slenderness coefficients, which a...

Paulownia kawakamii is a fast-growing timber tree. In this study, 21 primer sets were developed using an enriched genomic library. The genetic diversity was measured in one P. kawakamii population. The number of alleles per locus ranged from 2 to 19. The observed and expected heterozygosities varied from 0.158 to 0.842 (mean = 0.421) and from 0.376 to 0.952 (mean = 0.771), respectively. All 21 ...
