Germination Responses of Carnegiea Gigantea and Lemaireocereus Thurberi
Mcdonough WT. 1964. Germination Responses of Carnegiea Gigantea and Lemaireocereus Thurberi. Ecology. 45(1):155-159
The germination patterns of two large cactus species were studied in the laboratory by subjecting the seeds to various chemical and light treatments. Seeds of organ pipe cactus were collected from one individual plant at Organ Pipe Cactus National Monument, and the saguaro seeds from a plant in Tucson Mountain Park. Differences in germination responses were found to be minor. There was some difference in response to temperature, with organ pipe seeds germinating at higher temperatures than saguaro seeds, but the differences were not great. Brief bibliography, 2 figures, 3 tables.
