The present invention relates to a method of identifying tree lineage capable of expressing desired biological andor biochemical phenotypes and method of producing such trees. The system including a casing for immersing in the pool, and at least one filtering unit located within the casing. There is an electrode overlying the conductive structure and the substrate, and thus a Schottky contact forms between the electrode and the substrate. The network processor and traffic manager may be implemented in a single chip.
