<p</pThis study was conducted to compare regeneration density and biodiversity indices in the natural and man-made gaps in the Tutaki forests of Siahkal in Gilan province. Data were collected from 60 gaps (including 30 natural and 30 man-made gaps). The results of species composition indicated that three tree species including Diospyros lotus L., Carpinus betulus L. and Alnus glutinosa L. in bo...
In a free-air carbon dioxide (CO(2)) enrichment study (BangorFACE), Alnus glutinosa, Betula pendula and Fagus sylvatica were planted in areas of one-, two- and three-species mixtures (n = 4). The trees were exposed to ambient or elevated CO(2) (580 μmol mol(-1)) for 4 yr, and aboveground growth characteristics were measured. In monoculture, the mean effect of CO(2) enrichment on aboveground woo...
Plant viruses, especially tobacco mosaic virus (TMV) and cucumber mosaic virus (CMV) are serious threats to Rehmannia glutinosa which is a "top grade" herb in China. In the present study, TMV- and CMV-resistant Rehmannia glutinosa Libosch. plants were constructed by transforming the protein (CP) genes of TMV and CMV into Rehmannia glutinosa via a modified procedure of Agrobacterium tumefaciens-...
BACKGROUND AND AIMS Polyploidy in plants has been studied extensively. In many groups, two or more cytotypes represent separate biological entities with distinct distributions, histories and ecology. This study examines the distribution and origins of cytotypes of Alnus glutinosa in Europe, North Africa and western Asia. METHODS A combined approach was used involving flow cytometry and micros...
The objective of this study was to observe the effects of water extracts of Rehmannia glutinosa on the antioxidant system of Nrf-2 in diabetic mice induced by paraquat, and to provide the basis for its further development. Thirty male mice were randomly divided into the control group, model group and observation group. The mice in the model group and the observation group were treated with para...
alnus glutinosa, fraxinus excelsior and papaver rhoeas have long been used in folkloric medicine for the treatment of various ailments. as part of our continuing screening of plant extracts for activities, the extracts of a. glutinosa, f. excelsior and p. rhoeas have been screened for their antioxidant and antibacterial activities, as well as their general toxicity towards brine shrimps. among ...
