larger than any previously anticipated. Creation of new laboratories capable of producing more than 400,000 plants per week will test the ingenuity of laboratory managers and the skills of marketing departments. In recent years, numerous symposia have been held on various aspects of biotechnology and genetic engineering. Although micro propagation is the key to providing large numbers of genetically engineered plants, it is a topic that has been relegated to a minor position, or ignored completely, at such meetings. Accordingly, the time seemed propitious for a conference devoted solely to all aspects of micropropagation as applicable to horticultural crops.
