08-11-24 New options for plant development

A dynamic change of the specific leaf area index is introduced as part of the plant module. The switch Dynamic Specific Leaf Area allows the user to specify one additional parameter (Spec LeafArea Begin) value for the Specific Leaf Area in the Table Size and shape of growing plant . Note that the specific leaf are will then be defined by the new parameter at Growth Stage Index 1 and will be changed by linear interpolation towards the ordinary parameter value (Specific LeafArea) when reaching Growth Stage Index 2. Note that the growth stage development may need to be changed in connection with introduction of the new parameter to obtain the best timing of the leaf area development.

A more flexible dormancy for winter regulated plants is introduced by addition the Temperature Threshold for reaching dormance as a parameter instead of a previous fixed value of +5 ⁰C. The parameter (Dormancy Tth)  is located in the Growth stage table that is part of the Plant Growth module.
