The two
guard cells surround the central pore through which water is lost by plants.
The mean lengths ([micro]m) of
guard cells at the upper epidermis were 1.51 [+ or -] 0.92, 1.72 [+ or -] 0.15 and 1.62 [+ or -] 0.84 at Oluku, Agbor and sapele roads respectively while at the lower epidermis, the
guard cell lengths were 1.85 [+ or -] 0.40, 1.12 [+ or -] 0.64 and 1.71 [+ or -] 0.46, respectively.
endoplasmic reticulum (ER) and a rough
Guard cells ...
The shape of the
guard cells together and also the relation between polar and equatorial diameters of the stomata are indicative of its functionality (Rocha et al., 2007).
The
guard cells length on both surfaces was 22.3 [+ or -] 1.2 [micro]m; the
guard cells density on the adaxial surface was 345.7 [+ or -] 0.7 mm .
The number of stomata per unit area was 4, all the stomata were open and no closed stomata were present, the average length of
guard cells was 27.5 (25-30) um and average width of
guard cells was 6 (5-7) um.
Signalling drought in
guard cells. Plant Cell and Environment, 25: 229-237.
The multisensory
guard cell, stomatal responses to blue light and abscisic acid.
The
guard cells regulate the opening of the stomates, and the
guard cells are controlled by the water potential of the leaf.
We show that the use of the CMLD may enhance the detection performance and particularly if we add
guard cells in the range direction.
