Cone Development

A number of growth substances were applied to unpollinated strobili of Scots pine to test their effect on cone development. Unpollinated strobili are normally shed early in the growing season; the application of anti-auxins stimulated cone loss but indolebutyric acid and cytokinin reduced cone loss in comparison with unpollinated controls. The development of treated cones was associated with various morphological abnormalities. Mixtures of growth substances and pollen were found to be no more effective than pollen alone in terms of yield of seed.

Organic Nutrients

Defoliation reduces fruit set in the grape vine, but the mechanism of this effect is the subject of controversy. Effects of leaf removal on set have been attributed either to reduction in supply of organic nutrients to the developing bunch or to reduction in supply of fruit� setting factors. In the experiments reported here, small immature fruits developed on defoliated and decapitated vine cuttings, on cuttings in which leaves, apices, and roots were removed as they appeared, and on inflorescences which were cultured in the light in vitro on a medium devoid of exogenous growth substances. These results indicate that fruit set is regulated by supply of organic nutrients rather than by specific hormonal stimuli originating from organs external to the developing bunch.

In the last decade and a half, thin film research, particularly research into problems associated with epitaxy, has developed from a simple empirical process of determining the conditions for epitaxy into a complex analytical and experimental study of the nucleation and growth process on the one hand and a technology of very great importance on the other. During this period the thin films group of the University of Chile has studied the epitaxy of metals on metal and insulating substrates. The development of the group, one of the first research groups in physics to be established in the country, has parallelled the increasing complexity of the field.The elaborate techniques and equipment now needed for research into thin films may be illustrated by considering the plant and facilities of this group as characteristic of a good system for the controlled deposition and study of thin films.
