Problem understanding result of lighting regime-phytochrome

I just don't understand regime 3- why doesn't the daylight period following the darkness cause a huge boost in P730 levels, which tell the plant that it shouldn't grow? My problem is I don't know how fast the accumulation of P730 in daylight ...
