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...

Bitkiler, eski çağlardan günümüze kadar çeşitli tedavi yöntemlerinde kullanılmıştır. Sunulan çalışma ile Bitlis yöresinde geleneksel olarak tüketilen Plantago lanceolata’nın antioksidan ve antimikrobiyal özellikleri süperoksit dismutaz glutatyon-s-transferaz enzim aktiviteleri yanında Fe, Zn Cu düzeyleri incelendi. Antioksidan DPPH metodu süperoksitdismutaz glutatyon-S-transferaz saptanarak bel...

Phenotypic plasticity in growth (leading to compensation) and secondary chemical production (leading to induction) in response to herbivory are key defense strategies in adult plants, but their role in seedling defense remains unclear. A pair of greenhouse studies was conducted to investigate compensation and induction in seedlings and juvenile plants, using Plantago lanceolata (Plantaginaceae)...

1. Understanding how non-native plants respond to environmental variation, and the limits to these responses, is important for predicting plant invasiveness. Until now, the extent to which species' climatic limits differ on introduction to a new range has not been experimentally tested. Here, we investigate fitness responses to temperature and low-temperature limits to reproduction of native an...

BACKGROUND AND AIMS Herbivory and plant defence differ markedly among seedlings and juvenile and mature plants in most species. While ontogenetic patterns of chemical resistance have been the focus of much research, comparatively little is known about how tolerance to damage changes across ontogeny. Due to dramatic shifts in plant size, resource acquisition, stored reserves and growth, it was p...
