Fast-growing European buckthorn (Rhamnus cathartica) shrubs are aggressively invading woodlands in eastern and midwestern North America. Buckthorn casts dense shade, alters soil conditions, and may be allelopathic. We used greenhouse and field experiments to investigate aboveand belowground effects of Rhamnus on four herbaceous species native to southern Wisconsin. In the greenhouse, we assesse...

Phytohormones, including salicylic acid (SA) and jasmonic (JA) have the potential to ameliorate plant development tolerance deleterious effects of toxic metals like nickel (Ni). Therefore, current study was carried out evaluate SA JA's interactive effect on root antioxidative response two Alyssum inflatum Nyár. populations against Ni-toxicity. Two A. species under different Ni concentrations (0...

Bitki büyümesini teşvikleyici rizobakteriler (PGPR), bitkinin hastalıklara dirençli hale gelmesinde önemli rol oynamaları sebebiyle sürdürülebilir tarım sistemlerine katkı sağlamaktadır. Bu çalışmada, Çanakkale ili Ezine ilçesinin 6 km kuzeyinde bulunan serpantin yamaçlarında yayılan Alyssum pinifolium (Nyar, T.R. Dudley) bitki köklerinden alınan toprak örneklerinden elde edilen bakteri izolatl...

Seeds of eight commonly grown bedding plant species [Ageratum houstonianum Mill., Begonia × semperflorens Hort., Impatiens wallerana Hook., Lobularia maritima (L.) Desv., Petunia × hybrida Hort., Pelargonium hortorum L.H. Bailey, Salvia splendens F. Sellow, Tagetes patula] were germinated at pH values from 4.5 to 7.5 at 0.5 increments. Seeds were germinated in petri dishes on filter paper satur...

The invasive aquatic plant Eurasian watermilfoil (Myriophyllum spicatum L.) can hybridize with the related North American native species northern watermilfoil (M. sibiricum Kom.). Hybrid watermilfoil (M. spicatum × M. sibiricum) populations have higher fitness and reduced sensitivity to some commonly used aquatic herbicides, making management more difficult. There is growing concern that manage...
