I have observed that lateral root (LR) emergence in Arabidopsis roots increases when you transfer a seedling onto a fresh plate rather than when you just let it grow on the plate it germinated on. I observed this when the roots I let grow on a plate (MS+1% Suc+ 0.6% Phytagar) vertically for 15 days hardly had any emerged LRs compared to when I transferred a seedling of 6 days to a fresh plate and grew it for a further 5-8 days. I was growing them at a 16h/8h light/day cycle at conditions suitable for Arabidopsis growth.
