در این پژوهش به منظور بررسی ساختار لیگنین های دیوکسان و یورکمن(mwl) دوگونه پهن برگ (صنوبر, populus nigra ) و سوزنی برگ (سرو, cupressus sempervirens ) از روش مشتق سازی – گسست کاهشی (dfrc ) استفاده شد و ساختار لیگنین ها و فرآورده های حاصل (پلیمری و مونومری) با استفاده از فنون طیف سنجی 13c nmr و روشهای gc-mass و کروماتوگرافی نفوذ ژلی (gpc) مطالعه گردید. نتایج به دست آمده نشان داد که در این فرآیند,...
Phylogenetic comparisons of three nuclear DNA gene regions (nrDNA(ITS), 4-coumarate: CoA ligase, abscisic acid-insensitive 3) and a chloroplast region (petN-psbM) show that the Western Hemisphere cypresses (Hesperocyparis) is a well-supported clade quite separated from the Eastern Hemisphere cypresses (Cupressus). Based on these new data and previous data, a new genus, Hesperocyparis, is erecte...

Belowground processes are rarely considered in comparison studies of native verses invasive species. We examined relationships between belowground fine root production and lifespan, leaf phenology, and seasonal nitrogen dynamics of Lonicera japonica (non-native) versus L. sempervirens (native) and Frangula alnus (non-native) versus Rhamnus alnifolia (native), over time. First and second order f...
‘Huangguan’ pear (Pyrus bretschneideri Rehd. cv. Huangguan) is a widely planted cultivar in China. However, it susceptible to core browning after harvest. In this study, aminoethoxyvinylglycine (AVG) was applied at 200 mg L?1 one and two weeks prior harvest, its effects on fruit quality, ripening were investigated during storage ambient temperature (25 ± 1 °C). The results showed that there hig...
