Efficiency of nitrogen fertilization in spring wheat

An assessment of the nitrogen fertilization efficiency should not only include quantitativeand qualitative yield changes, but also an analysis of formation some indicators such as: Nharvest index (NHI), N use efficiency (NUE), N utilization efficiency (NUtE), N agronomicefficiency (NAE), N physiological efficiency (NPE) and N apparent recovery fraction (NRF).The objective of the study was the e...

Glycoproteins from Russian wheat aphid infested wheat induce defence responses.

Elicitors are molecules which can induce the activation of plant defence responses. Elicitor activity of intercellular wash fluid from Russian wheat aphid, Diuraphis noxia (Mordvilko) infested resistant (cv Tugela DN), and susceptible (cv Tugela), wheat (Triticum aestivum L.), was investigated. Known Russian wheat aphid resistance related responses such as peroxidase and beta-1,3-glucanase acti...

Inheritance of Russian Wheat Aphid Resistance in Spring Barley Germplasm Line STARS-9577B

A damage rating scale for wheat and barley seedlings was developed by Webster et al. (1991) based on visual The Russian wheat aphid (RWA), Diuraphis noxia (Mordvilko), rating of leaf chlorosis, leaf streaking, and leaf spotting. has become a major pest of barley (Hordeum vulgare L.) in the This visual rating was on a scale of 1 to 9 (1 no western USA.
