Spline interpolation neutralizes random effects of environment and cultivation procedure to measured parameters (number and length of produced flowering shoots). This procedure finds some biological rhythms (internal clocks) of flowering shoots. Periodic environment, sigmoid law of growth and property of ergodicity allow reconstructing standing parameters of flower population. It was discussed two linked processes: radiation transmission and leaf area expansion. The simulation aims to measure the synchrony in time of these processes. Time behavior of this measure says about quality-cultivated management.
