agakaron24ParticipantHello,
I had a laboratorium classe and I need to make a report in the following subject:
"The effect of potassium and abscisic acid on the mechanism of stomatal opening"
we were using:
KCL 0 10 50 100 200 500 (mM) and
ABA zero and 10-3 (M)is there anybody with knowledge that can provide some explanation, information or even some documents about this topic?
I would really appreciate some help.
Thank you.

well,opening of stomata is due to difference in osmatic concentration.u know[i assume] guard cells r the only epidermal cells that contain chloroplast.during day time,the following events hapen which opens stomatal pore.
synthesis of ATP-driving out of H+ IONS out of guardcells-influx ofK+ IONS ALONG WITH CL- IONS-INCREASE in osmolarity of guard cells-inflow of water-opening of cells due to bulging
ABA plays an imp.role in controlling transpiration by influencing the flow of water.
