The biometric methods such as ANOVA and comparative analysis
were applied to investigation of growth dynamics for Lepidium sativum L. under
control conditions after the morning and the evening laser photo-activation of
its seeds. It is established that laser irradiation at the evening period
reduces the time of seeds germination for 10–12 hours in comparison with the
morning one. Out of the investigated factors effecting growth parameters,
namely regime of laser irradiation (uninterrupted or scanned), period of
irradiating and duration of growth, the variation of growth speed on the
sequential time intervals is dominating. The effect of scanned irradiation is
more strong than uninterrupted one. The influence of time period of seed
photo-activation and sowing is statistically significant only in interaction
with other investigated factors.
