Potassium plays an important role in plant nutrition, influencing many physiological processes such as carbohydrates translocation, protein synthesis, enzymes activation, stomata opening and closure, turgor pressure regulation and control of C[O.sub.2] input and [H.sub.2]O exit in stomata and the subsequent concentration at plant mesophyll cells during the transpiration process (Schreiner et al., 2013).
During development, the creation of different shapes fundamentally requires the integration of genetic, biochemical and physical mechanisms.In plant, a stiff pecto-cellulosic network encapsulates cells and counterbalances stress created by turgor pressure inside the cell, thereby controlling cell shape.
grisea is influenced externally by surface feature and internally regulated and/ or modulated by several cascading biochemical pathways ultimately leading to turgor pressure development for penetration.
Other than affecting the bulliform cells, water deficit also causes the guard cells to lose their turgor pressure [66], thus leading to stomatal closure [67].
The major physiological mechanism to maintain leaf turgor pressure by decreasing osmotic potential is osmotic adjustment.
Further research will be needed to explore the functional link between traits and tree growth response to climate, including the integration of some hard traits that are not typically included in functional trait screenings, including leaf and stem anatomies and leaf turgor pressure [49, 66, 67].
[20] which showed that the water deficit resulted in a loss of turgor, thus minimizing the force from the turgor pressure. The reduction in cell growth might explain the inhibition of growth of organs in plants evolving under this constraint [21,22].
Illumination from above results in greater turgor pressure in the abaxial motor cells compared to the adaxial motor cells; while leaves in the dark have the reverse turgor gradient [4,19, 20].
