Notes:
Lactuca sativa L., lettuce (Arctic King) fruit germination is inhibited in the light at temperatures above 27°C(±1.5°). This value, which is precise and repeatable is referred to as the upper temperature cut-off point, and is characteristic for a particular species. It was found, that this cut-off point is shifted upwards by applying kinetin solutions (0.1–1 mg/1) or downwards by applying (±)-abscisic acid solutions (over 1 mg/1), the amount of shift being proportional to the level of active compound. In the presence of both compounds a balance was achieved. Effects of stimulators and inhibitors can most explicitly be described by reference to the direction and magnitude of the shift in the upper temperature cut-off point, which results from their application.
