fT {growR}

Temperature limitation

Description

Threshold function representing growth limitation by temperature.

Usage

fT(t, T0 = 4, T1 = 10, T2 = 20)

Arguments

t

float Temperature in degree Celsius.

T0

float Photosynthesis activation temperature in degree Celsius.

T1

float Photosynthesis plateau temperature in degree Celsius.

T2

float Photosynthesis max temperature in degree Celsius.

Details

Photosynthesis is suppressed below T0, increases until it reaches its maximum at temperatures in the interval (T1, T2). For temperatures exceeding T2, photosynthetic activity decreases again until it reaches 0 at a final temperature of 40 degree Celsius.

Value

A value in the range (0, 1), acting as a multiplicative factor to plant growth.

Examples

fT(4)
fT(10)
fT(15)
