Establishment Limitations of Sensitive Target Species Potentilla alba L. in Grasslands Restored on Arable Land

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Species in grasslands restored from former arable land have multiple obstacles when establishing. Understanding whether these limitations stem from soil chemical or microbial differences could help to create suitable environments for specific target and other species with similar requirements.

Plant responses to iron nutrition with emphasis on the underutilized crop tef (Eragrostis tef): A review

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Iron (Fe) deficiency limits the physical health, cognitive development, and economic output of billions of people globally, especially children and productive‐age women. Tef is an underutilized and stress‐resilient crop, which is becoming popular for its grains containing high bioavailable Fe and has the potential to mitigate Fe deficiency.

How does leaf age affect performance? A comparative study of essential oils from young and mature Eucalyptus globulus leaves in crop protection

open access: yesPest Management Science, EarlyView.
Leaf age influences metabolomic profiling but not bioactivity of Eucalyptus globulus essential oils. Leaf age affects volatile levels of young and adult E. globulus oils, but not their bioactivity. Young leaf essential oil had higher contents of α‐ and β‐pinene. AEEO had higher levels of 1,8‐cineole and trans‐pinocarveol.

Steps Toward a Natural System of the Dicotyledons

open access: yes, 1991
Embryological character states are mapped on the diagrams of dicotyledons (G. Dahlgren 1989). The often well-defined pattern of distribution forms a basis for discussing and clarifying phylogenetic relations.
