Reduces daily temperature increment by vernalisation and photoresponse.

Vernalisation

Vernalisation days

The daily increment of vernalisation days is determined by daily average temperature iDAVTEMP

\[ \begin{eqnarray} VDI(iDAVTEMP) Ungültige Eingabe: "&" = Ungültige Eingabe: "&" \left\{ \begin{array}{l} 0 Ungültige Eingabe: "&" \text{if} \quad iDAVTEMP \lt cTlowCritical\\ \frac{iDAVTEMP - cTlowCritical}{cTlow - cTlowCritical} Ungültige Eingabe: "&" \text{if} \quad cTlowCritical \le iDAVTEMP \lt cTlow \\ 1 Ungültige Eingabe: "&" \text{if} \quad cTlow \le iDAVTEMP \lt cThigh \\ \frac{cThighCritical - iDAVTEMP}{cThighCritical - cThigh} Ungültige Eingabe: "&" \text{if} \quad cThigh \le iDAVTEMP \lt cThighCritical \\ 0 Ungültige Eingabe: "&" \text{if} \quad cThighCritical \le iDAVTEMP\\ \end{array} \right. \end{eqnarray} \]

And sVernalDays is incremented by VDI(iDAVTEMP).

Vernalisation factor

VernalisationFactor (VF) is determined by the sVernalDays (VD)

\[ \begin{eqnarray} VF(VD) Ungültige Eingabe: "&" = Ungültige Eingabe: "&" \left\{ \begin{array}{l} 0 Ungültige Eingabe: "&" \text{if} \quad VD \lt cVernalDaysMin\\ \frac{VD - cVernalDaysMin}{cVernalDaysMax - cVernalDaysMin} Ungültige Eingabe: "&" \text{if} \quad cVernalDaysMin \le VD \lt cVernalDaysMax \\ 1 Ungültige Eingabe: "&" \text{if} \quad cVernalDaysMax \le VD \\ \end{array} \right. \end{eqnarray} \]

Photoresponse Factor

DayLength is calculated from current DOY and cLatitude

Photoresponse curve is interpolated from cPhotoresponseTable, which is a double array, holding the duration (in hours) in the even entries and the coresponding factors in the odd entries.

The PhotoresponseFactor is then chosen from the interpolated curve according to the Daylength.

After anthesis, no daylength effects are taken into account (PhotoresponseFactor = 1).

Applying Vernalisation and Photoresponse

Before anthesis:

\[ \begin{eqnarray} RTSUM Ungültige Eingabe: "&" = Ungültige Eingabe: "&" iTSumBaseAnt \cdot Min(PhotoresponseFactor, VernalisationFactor) \end{eqnarray} \]

After anthesis:

\[ \begin{eqnarray} RTSUM Ungültige Eingabe: "&" = Ungültige Eingabe: "&" iTSumBaseMat \cdot Min(PhotoresponseFactor, VernalisationFactor) \end{eqnarray} \]

cApplyPhotoresponse and cApplyVernalisation control whether photoresponse, vernalisation or both are applied. If the control variables are false, the coresponding factor is always 1, meaning that the effect is not applied.

The state sVernalDays has to be reset on each sowing. Therefore the input iDoSow has to be provided.
