GROWTH RETARDANTS AS AIDS IN ADAPTING NEW FLORICULTURAL CROPS TO POT CULTURE |
| Authors: | Tim D. Davis, A. Andersen |
| Abstract:
Many floricultural crops are too large for standard container culture. Chemical growth retardants may be useful in manipulating the shape, size, and form of new floricultural crops until improved shorter cultivars can be obtained via breeding and/or biotechnology. In evaluating the potential utility of a growth retardant on a new crop, a number of criteria must be considered: ease of application, dosage range and timing, consistency, availability of antidotal treatments, effects on vegetative and reproductive development, effects on post-production quality and performance, and economics of application. A number of compounds have potential for regulating the size of new floricultural crops. Our paper discusses general plant responses to growth retardants as well as specific types of growth retardants including onium compounds, daminozide, pyrimidines, triazoles, and pinching agents. | |
