The full programme, included .17 main ppa ers and. 21 shorter contributions on the varied aspects of the subectj . The. topic of greatest importance ..... and interest to agrometeorotogy was the fundamental work on the physics of the boundary micro-layer m the surface vegetation. This revolved both the theoretical and experimental investigation of the transport and exchange of energy, momentum, water vapour and carbon dioxide. , and basic research on the.entire, process of photosynthesis.. . In recent ..... years techniques have been developed in m~cro-meteorology and. micro-physics. .. that are essentml for progress m the experimental side of plant physiology. The discussions at th~s symposium made it clear lhat although many differences of opinion and methods of approach still exist, considerable progress is being made in a difficult and complex subject in several countries.
It is appropriate to remark that the bulk of this research is being carried out by scientists who do not belong to their national meteorological services, which is understandable because the work involves expert knowled e in both biology and micro-meteorology It is all the more important, g . . therefore, that UNESCO publish a full report on the meeting to provide an invaluable record of the present state of research in this fundamental aspect of agrometeorology, so that all meteorologists can be aware of the current developments.
