Model predictions of the water balance of a 100 g Actinidia chinensis ‘Hort16A’ fruit for the final 30 d of fruit development under Californian meteorological conditions, incorporating the effect of changes in parameter values for fruit hydraulic conductivity (Kf) and surface conductance to water vapour (gc). (A) Fruit transpiration, and xylem and phloem flows under normal conditions of measured Kf and gc. (B) Change in fruit fresh mass calculated as the starting fresh mass plus the cumulative sum of transpiration+xylem flow+phloem flow, using measured Kf and gc, with Kf doubled, or gc halved.
