      Hello,

      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.
