A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

This report consists of three major sections which are: progress made on the development of a generic plant growth model, progress made on the holistic ecosystem model, and a summary outlining future directions of our modeling efforts. The major accomplishments of the plant growth modeling have been the identification and implementation of components for the photosynthesis module, development of a plant canopy module, and further refinement of the various modules that make up the basic structure for a generic plant growth mode. Research examined several implementations of a leaf-based, CO{sub 2} responsive, photosynthesis model that incorporates information at the enzyme-kinetics level. Also presented, are several models of forest canopies, transpiration, and photosynthesis.
