Ebook: Plant Growth Substances 1970: Proceedings of the 7th International Conference on Plant Growth Substances Held in Canberra, Australia, December 7–11, 1970

At the 6th International Conference on Plant Growth Substances, held in Carleton University, Ottawa in 1968, it was decided that the 7th should be held in Czecho­ slovakia, following an invitation by Dr. Kutacek. Historical events intervened and in 1969 another venue was sought. An offer from the Academy of Science in Canberra was accepted by the steering committee. This left rather less time than is desirable to organize an international meeting of this nature and it was with surprise and great relief that the Organizing Committee in Canberra welcomed the arrival of 183 delegates, including a relatively large overseas contingent, to the meeting in December, 1970. The aim of these Conferences is, of course, to provide a forum for discussion of new work and recent trends, both in the lecture sessions and in conversation. Although many of those who initiated these meetings (e.g. Skoog, Went, Blackman, Bennet-Clark) were absent from the Canberra conference - some have retired -it was good to see present so many of the new generation of research workers in this field.
