Abstract
In daylight growth chambers cutting-propagated plants of Pelargonium zonale cv. ‘Mars’ were cultivated at a large scale of mean temperatures and daily thermoperiodicities.
The relation of the growth period to the 24 hours mean temperature can be described by a hyperbolic function.
An additional effect is achieved by an increasing daily thermoperiodicity which depends on the temperature level.
Plant weight at anthesis can be parameterized by a corresponding function.
Having the same independent variables, both functions can be combined to one model.
Due to subjective impressions, which are difficult to quantify, a comprehensive mathematical description of the marked quality was not achieved.
