wild trees
The extractable monoterpenes from needles of two groups of trees - 4-year-old clonal and 20-year-old wild trees - were studied with respect to the influence of individual constitution, needle age, whorl position, and position on branch.
      
Wild trees exhibit a very high variation from tree to tree, which obscures the influence of needle age and position.

Wild trees exhibit a very high variation from tree to tree, which obscures the influence of needle age and position.
      
In addition, fluctuations in mature needles were shown for a set of ten wild trees.
      
Our simulations show that even partial sterility can provide very substantial reductions in gene flow into wild trees.
      
An extrapolation of the species accumulation curve among stands indicated that the whole system, composed of more than 100 coffee plantations, may harbour as many as 34 species of wild trees.
      
However, the prospect of altering wild trees' genomes as an unintended consequence of the development of a com mercial crop raises many red flags.
      
These GE trees might also transfer the Bt toxin to wild trees, thereby perpetuating the toxin's production in ecosystems.
