| Abstract:
The resistance of greenhouse-grown cucumbers to summer diseases and insect pests may be initiated by exposure or inoculation. Acquired resistance is developed in the inoculated leaf, as well as in leaves on the same plant that do not receive an inoculation. A similar mechanism of systemic acquired resistance (SAR) may exist to confer resistance to high-temperature stress. Salicylic acid (SA), which is a chemical inducer of SAR, and SAR gene expression were induced by high-temperature treatments in greenhouse-grown cucumbers, providing evidence for the existence of SAR to heat stress. | |
