Abstract

In many ways the first bloom is off the rosy image of the new cell culture with its promise for early development of new interspecific plants through somatic hybridization, incorporation of useful genes through protoplast fusion and gene transformation, and selection of mutant cells with desirable genetic traits for transmission to regenerated plants. If progress in cell culture has been slower than anticipated, a little reflection will help us to realize that this is not unusual in science. We might examine the satisfaction we feel in our knowledge of the field of intermediary metabolism, but only a little reminiscence leads one to the realization that this satisfaction is the product of leaps of creativity and technological advance, but also of many false starts and a great deal of painstaking effort.

Abstract

Because of new developments and sustained interest in chemical regulation of plant processes, it was considered appropriate to make this field the subject of a major symposium for the 1968 annual meetings of the Society. The primary purpose of the symposium was to present an up-to-date understanding of chemical regulation of plant processes. The choice of topics and speakers was made with the help of a number of active investigators in the field.

Abstract

Applications of 2-chloroethylphosphonic acid to field grown cantaloupes resulted in yellowing of leaves, early abscission, apparent ripening of immature melons and increased total and marketable yields of full-slip melons. The percentage of soluble solids was slightly lower in treated melons.
