Recent work has made progress in relating the size of stomata to stomatal functioning and, in particular, the speed of opening and closing and its implications. Calculations of the influence of stomatal size on the potential rate of osmolarity increase, assuming size-independent ion influx rate per unit area of guard cell plasmalemma set at the value found in large (60 μm long) stomata, show that 10 μm long stomata could have at least a 6-fold higher rate of osmolarity increase. There could be… CONTINUE READING
