| Abstract:
Installation of landscape plants is considered a cost-effective way to reduce adverse effects of polluted or stressful environments. Tolerance of various plants to environmental and man-made stresses varies dramatically with species and cultivar. Nebraska and Hungary have many climatic and geophysical similarities and researchers have learned much about plant environmental stress and pollution tolerance. Therefore, a cooperative program for testing and introduction of stress-tolerant ornamentals was initiated in 1988 between the University of Nebraska-Lincoln and the University of Horticulture and Food Industry and was sponsored by the US-Hungarian Joint Fund for Science and Technology (JFNo.385) beginning in 1994. Key components of the project were (1) Exchange of propagation materials; (2) Primary propagation research; (3) Nursery tests for cultural properties; (4) Field tests for stress-tolerance and urban hardiness at three Nebraska Statewide Arboretum sites and Lincoln, Budapest and Veszprem streets and two Hungarian arboreta. About 80 Hungarian genotypes have been propagated in Nebraska (25 now in nursery and field tests). In Hungary, about 70 American cultivars have been introduced and tested, including 20 for use as street trees. The project also included visits of three Hungarian scientists to the USA and three Nebraska scientists to Hungary in 1994 and 1996, jointly organized professional meetings, exchange of students for them to gain practical experience, and a Hungarian student completing her PhD degree at the University of Nebraska. Further details of species and cultivars exchanged and studied, new propagation approaches and cultural and practical knowledge gained will also be presented. | |
