Resolving the effects of functional traits on tree growth rates: The influence of temporal dynamics and divergent strategies by leaf habit

open access: yesJournal of Ecology, Volume 113, Issue 11, Page 3191-3209, November 2025.
Functional traits are not consistently associated with tree growth rates but instead reflect dynamic resource acquisition and investment strategies over time and between deciduous and evergreen species. Despite this variability, our findings confirm the utility of functional traits to predict tree growth rates, especially when trait effects are ...

Somatic embryogenesis in Picea omorika (Panč.) Purk

open access: yesActa pharmaceutica, 1995
Somatic embryogenesis in Picea omorika was successfully induced on LP medium supplemented with 10 uM 2, 4-D and 5 uM BA. Maturation was achieved on one half strength LP medium supplemented with 20 uM ABA.The prottein pattern of embryogenic callus culture showed two characteristic proteins that belongs to the storage protein group.
