Following a global trend, the lack of reliable access to skilled labour is causing critical issues for the effective management of apple orchards. One of the primary challenges is maintaining skilled human operators capable of making…

Control of gas exchange between a leafs interior and the surrounding air is accomplished by variations in the turgor pressures in the small epidermal and guard cells that cover the leafs surface. These pressures respond to changes in light…
