THE MORPHOLOGY AND PHYSIOLOGY OF BULBOUS PLANTS PAST, PRESENT AND FUTURE |
| Author: | A.R. Rees |
| Abstract:
The sympodial growth habit probably evolved in a uniform tropical environment, and the later development of storage tissues led to a life-form well adapted to a Mediterranean climate. The productivity of two tulip cultivars is examined in relation to bulb spacing, and suggestions are made about the ideal tulip of the future, an ideotype which has high potential productivity, low competitive ability and a yield of a moderate number of large daughter bulbs. A longer growing season would be advantageously achieved by decreasing summer dormancy, and a shorter low-temperature requirement would benefit early forcing. | |
