Plants of the genus Salvia produce various types of phenolic compounds and tanshinones which are effective for treatment of coronary heart disease. Salvia miltiorrhiza and S. castanea Diels f. tomentosa Stib are two important members of the genus. In this study, metabolic profiles and cDNA-AFLP analysis of four samples were employed to identify novel genes potentially involved in phenolic compo...

The aboveground biomass, litterfall and its accumulation, litter weight loss due to decomposition and nutrient pools in relation to soil properties were analyzed in a Castanea sativa Mill. stand in order to better understand the recycling of elements associated with the turnover of organic matter. The aboveground biomass and the nutrient content were estimated by harvesting eight trees. In orde...

Thirteen species of Tenebrionidae are newly reported for New Brunswick, Canada. Paratenetus punctatus Spinola, Pseudocistela brevis (Say), Mycetochara foveata (LeConte), and Xylopinus aenescens LeConte are recorded for the first time from the Maritime provinces. Platydema excavatum (Say) is removed from the faunal list of New Brunswick, and the presence of Platydema americanum Laporte and Brull...

Allozyme genetic variation in 12 populations of the endangered Castanea pumila var. pumila (Allegheny chinkapin), sampled across the natural range of the species in the United States, was evaluated using 11 loci from seven enzyme systems. At the species level, the percentage of polymorphic loci (Ps) was 72.7 %, the mean number of alleles per locus (As) was 1.9, the mean number of alleles per po...

A new species of Chaco Tullgren, 1905 is described and illustrated from the Andean foothills of Mendoza province, western Argentina. This is the tenth species of the genus and the first record of Chaco in Mendoza. An updated key is presented for all Chaco species. The cladistic analysis based on a previously published morphological character matrix resulted in the consensus tree: (C. obscura, C...

The global climate change recorded over recent years may prompt changes in phenological events. The present study sought to analyse the varying impact of changes in weather conditions at different times of the year on woody-plant flowering, by analysing recent trends in airborne count for 3 pollen types abundant in Galicia belonging to the Fagales order: Alnus, which flowers in early winter; Be...

Bu çalışmada seleksiyon çalışmaları ile öne çıkan 17 kestane (Castanea sativa Mill.) çeşit/genotip ülkemizde yetiştiriciliği yaygınlaşan iki hibrit x Castanea crenata) çeşit olmak üzere toplam 19 çeşit/genotipte erkek çiçek yapıları incelenmiş ve stamen tipi belirlenmiştir. Kestane çeşit/genotiplerin beşinin stamensiz, birinin kısa stamenli, dördünün orta boyda stamenli dokuzunun uzun olduğu Çe...
