I'm writing a lab manual for my student of the Tree Fruit Ecophysiology Course at my University (in Albanian language). Two of the laboratory topics will deal with field methods and instrumentation for light and temperature measurement. I'm using as a basis the relevant chapters from "Plant Physiological Ecology - Field Methods and Instrumentation" but obviously there is a lot of progress since 1989 in this fields. Therefore, although valuable for the structure and principles, I'm looking for pertinent reviews, either on individual methods/instrumentation, i.e. photographic or radiation measurement or more generalised reviews. Please advice!
