The present study addressed the question whether attentional capture by abrupt onsets is affected by object-like properties of the stimulus field. Observers searched for a target circle at one of four ends of two solid rectangles. In the focused attention condition the location of the upcoming target was cued by means of a central arrowhead, whereas in the divided attention condition, the targe...

Associations of alleles of the acid phosphatase-3 locus with the different third-chromosome inversions from different populations of D. pseudoobscura are described. We observe only the allele AP-3(1.0) in the Standard and Arrowhead inversions and the allele AP-3.98 in the Santa Cruz, Treeline, Cuernavaca and the Pikes Peak arrangements. The Chiricahua gene arrangement is polymorphic.

Plantain is the most important crop for Peruvian Amazonian population, developed in recent alluvial soils rich nutrients, but fragile and susceptible to degradation. Therefore, impact of permanent cultivation was evaluated, through modelling, on indicators soil quality production plantations Musa paradisiaca L. var. Harton, Aguaytia River valley, Peru. The treatments were areas with...

Background: Plantago lanceolata L. (ribwort plantain) and major (broadleaf are widely used in ethnobotanical studies for treating various diseases. This study aims to investigate the antimicrobial activity chemical compounds of these plants. Methods: The leaf extracts P. were fractioned using different solvents. phytochemical screening was carried out by gas chromatography-mass spectrometry (GC...

The objective of this study was to evaluate genetic variability and select putative mutants of Terra Maranhão plantain cultivar (AAB genome) subjected to gamma radiation based on agronomic data and inter simple sequence repeat molecular marker profiles using the Ward-MLM strategy. A total of 233 irradiated plants and 41 controls were assessed. The agronomic and molecular data were subjected to ...

In the recent years synthetic drugs have been widely replaced with herbal medicines and plant extracts because of their little undesirable and extensive beneficial effects. Plantago major L. (also known as plantain and way bread) is a member of the Plantaginaceae family. Leaves and seeds of the plant have been widely used in folk medicine for various purposes, including treatment of an extensiv...

The objectives of the present field study were to examine the soil enzyme activities in the soil root zones of Plantago lanceolata and Plantago major in different heavy metal contaminated stands. Moreover, the investigations concerned the intensity of root endophytic colonization and metal bioaccumulation in roots and shoots. The investigated Plantago species exhibited an excluder strategy, acc...
