Table 4.

Frequency of occurrence for different channel types in cell-attached patches of Pokkali and IR20

	Inward conductance	Outward conductance	Voltage-independent conductance	Total number of patches
Pokkali(con)	16%	11%	76%	38
Pokkali(NaCl)	0%	n.d.	75%	16
IR20(con)	12%	5%	78%	39
IR20(NaCl)	0%	n.d.	77%	26

The occurrence of inward, outward, and voltage-independent conductances with unitary conductances listed in Table 2 was determined for each cell-attached patch from control (con) and salt-grown (NaCl) plants. n.d., Not determined.
