Production of high quality seeds is of fundamental importance for successful crop production. However, knowledge of the effects of increased temperature resulting from global warming on seed quality of alpine species is limited. We investigated the effect of maternal environment on seed quality of three cultivars of the leguminous forage species Vicia sativa, giving particular attention to temp...

•The name Cryptotis peregrina (Merriam, 1895) previously encompassed two separate populations of a small-eared shrew of the Cryptotis mexicana-group inhabiting the Sierra de Cuatro Venados and the Sierra de Miahuatlan in Oaxaca, Mexico. Analysis of museum specimens from these two populations, including the type series of C. peregrina, indicates that they are neither conspecific nor even sister ...

The correct identification of Biomphalaria oligoza, B. orbignyi and B. peregrina species is difficult due to the morphological similarities among them. B. peregrina is widely distributed in South America and is considered a potential intermediate host of Schistosoma mansoni. We have reported the use of the polymerase chain reaction and restriction fragment length polymorphism analysis of the in...

The bark of Anadenanthera peregrina (L.) Speg and Anadenanthera colubrina (Vell.) Brenan were characterized in relation to anatomical and chemical features. The barks were similar and included a thin conducting phloem, a largely dilated and sclerified non-conducting phloem, and a rhyridome with periderms with thin phellem interspersed by cortical tissues. Only small differences between species ...

(Anatomical and ultrastructural aspects of root and mycorrhiza of Anadenanthera peregrina (L.) Speg. var. falcata (Benth.) Altschul (Leguminosae-Mimosoideae)). A. peregrina var. falcata form mutualistic symbiosis with arbuscular mycorrhizal fungus. An anatomical and ultrastructural study was carried out to analyze some aspects of this simbiotic association as well as some root features. The res...

increases forage production and economic production in rainfed condition requires attention to agricultural issues such as determination of appropriate sowing depth. so in order to determine the effect of different sowing depths of vetch this experiment was conducted in agricultural research station of maragheh as strip plot based on randomized complete block design with three species of vetch ...

Specific morphological and biochemical characteristics of seeds can cause oxygen deficiency within maternal and embryonic tissues. In this study, optical sensors were used to measure O(2) profiles across developing seeds of Vicia faba and Pisum sativum and developmental and environmental modulations of internal O(2) levels were studied. In addition, the metabolic state of developing embryos was...

this experiment contained four vetch lines (vicia panonica ) that conducted in two locations (faruj and bojnourd) in 2005-2006 in rcbd design with four replications under dryland conditions. analysis of variance indicated that there were significant differences among lines in different locations about all traits, except 100-seed weight. the interaction of genotype×location was significant on al...
