    Sammanfattning : Natural plant growth regulators (phytohormones) are a group of organic compounds which, in very small amounts, act as regulators of physiological processes in plants.Methods were developed for the analysis of phytohormones in samples from Norway spruce (Picea abies (L.) Karst.) and Scots pine (Pinus sylvestris (L. LÄS MER

    Sammanfattning : Fetal growth restriction (FGR) is, next to prematurity, the second leading cause of perinatal morbidity and mortality. To reduce perinatal morbidity and mortality it is important to identify such fetuses in utero in order to monitor their development, and to determine the most optimal time for delivery. LÄS MER
