NEW VISTAS IN PLANT PROPAGATION
Hudson T. Hartmann
The plant propagator and the nursery industry are in the most fortunate position of being able to benefit from the result of research in many disciplines and many applied fields.
Plant breeders are continually developing new plant material, some of which eventually becomes important in the nursery trade. Plant introduction programs and arboreta often bring in valuable new germplasm to be used directly, or as a gene source for introducing, by plant breeding, new characteristics into present plant material. The biochemists, plant physiologists, and botanist develop new growth regulators, herbicides, fertilizers, and such new techniques as tissue culture. They also study plant structure, adaptation to the environment, and plant functions, to give us a better understanding of plant behavior. Entomologists and plant pathologist develop new chemicals and new techniques for controlling insects and diseases, while the engineers design new propagation facilities and equipment used for such
