Opening of stomatal pore is regulated by guard cells. When guard cells gain water, they become turgid. In turgid guard cells the thin outer wall is pushed outside, which pulls the thick inner wall outside. This causes opening of stomata.
WebRole of potassium K+ in stomatal opening is now universally accepted. This was observed for the first time by Fujino (1967) that opening of stomata occurs due to the influx of K + ions into the guard cells..
