Quantifying interannual change in water status of woody plants using stable carbon isotopes provides insight on long-term plant ecophysiology and potential success in variable environments, including under-utilized agricultural land for biomass production and highly disturbed sites for phytoremediation applications. We analyzed dC values in annual ring-wood of four shrub willow varieties used f...

AlthoughmanyMediterranean and xeric plant species enhance their xanthophyll-mediated thermal dissipation under drought conditions, there has been limited research on photoprotective mechanism in droughted plants from other habitats. To investigate whether wetland plants utilise this mechanism under drought conditions, and whether species differ in their responses depending on their habitat affi...

Background Salix koreensisis native to Korea, Japan and China, is a deciduous broadleaved tall tree growing throughout Korea. This species is dioecius and planted along the streets and for landscaping. Along the rivers the species grows well reaching up to 20 meters in height. Trees bloom in April and fruits ripe in May. This study was carried out to investigate the genetic diversity of S. kore...

Assessment of crop nitrogen use efficiency (NUE) is important in agricultural research. Various approaches exist to analyze NUE. A recently proposed NUE concept is further developed and a calculation tool for practical use presented. A critical component in the NUE concept is the plants’ mean nitrogen (N) content during the main growth period (N’). The N’ is delimited by the critical crop pheno...
