RHYTHMIC GROWTH. "Although endogenous control of rhythmic growth was described in oaks more than a century ago, the mechanisms involved have not yet been elucidated." http://jxb.oxfordjournals.org/content/66/22/7113.full View in LinkedIn

SYMBIONT. "Interactions with mycorrhizal fungi should be considered in studies on the rhythmic growth of trees, because this ecologically obligatory symbiosis of roots not only enhances the acquisition of soil nutrients and stimulates photosynthesis of trees, but also changes their allocation among plant parts." http://jxb.oxfordjournals.org/content/66/22/7113.full View in LinkedIn

GROWTH CYCLES. "The growth of many trees is not continuous, but is interrupted by episodic rest phases. Pedunculate oak (Quercus robur L.), a major forest tree species in European forests, displays rhythmic growth with successive growth/rest phases of fixed periods of 18–22 d under constant culture conditions, which reflects the endogenic character of this trait." http://jxb.oxfordjournals.org/content/66/22/7113.full View in LinkedIn

INTERNAL CLOCK OF TREES. "Endogenous rhythmic growth in oak trees is regulated by internal clocks rather than resource availability. The results indicate that rhythmic growth involves dramatic oscillations in plant metabolism and gene regulation between below- and above-ground parts. Ectomycorrhizal symbiosis may play a previously unsuspected role in smoothing these oscillations without modifying the rhythmic growth pattern." http://jxb.oxfordjournals.org/content/66/22/7113.full View in LinkedIn
