Abstract
The purpose of this paper is to present a theoretical account of the phosphorus nutrition of plants in soils, including some of the evidence and thinking related to it. Because these remarks are directed to the “nutrient-solution fraternity,” a comparison of nutrient solutions and soils in respect of certain aspects of phosphorus nutrition may be an appropriate introduction.
lettuce. We posed three questions: 1) Does continuous irradiation with alternating red/blue light enhance plant growth? 2) Does it affect nutritional quality, including concentrations of sugar, ascorbic acid, and anthocyanins? 3) What mechanisms are
Abstract
Physiological problems observed during postharvest handling of deciduous fruit crops often originate during production as a result of climatic, nutritional, or other cultural factors. Sometimes the likelihood of a problem occurring is partially under genetic control. For a postharvest physiologist to be fully effective in evaluating a problem, he must know the cultural history of the commodity with which he is working. Similarly, the researcher studying cultural factors should know the relationships between treatment variables and quality traits. Often this can best be accomplished by collaboration of researchers working in both fields, but one individual with proper background and interest may also acquire relatively complete information. I consider this symposium highly appropriate to point out interrelations between plant nutrition and commodity quality, and the need for adequate information on quality aspects of nutritional research to enable accurate interpretation of results.
Abstract
When one searches the literature for information pertaining to the nutrition of woody ornamental plants it soon becomes obvious that there has not been too much published in this field. And most of the experimental work on the nutrition of trees has been concerned with varying combinations of nitrogen, phosphorus and potassium. Also, most of the work that is reported was done in the field, either to trees growing in the landscape or in nurseries and as a result most of the studies report a positive response only to the application of nitrogen and little or no response to the application of phosphorus or potassium. A brief review of some of the literature on fertilizer experiments is contained in the works of Wikle (18) and Himeleck (9). Since this symposium is concerned with potassium in horticulture, I will confine most of my remarks to the place that this mineral element has on the growth and development of woody ornamental plants.
