The paper summarises the effects of the common weather variables radiation (R), windspeed (W), air temperature (T) and relative humidity (RH) on fruit transpiration, and of fruit transpiration on fruit mineral accumulation (particularly calcium, Ca) in apricot and kiwifruit. The effects of T and RH on transpiration are combined in vapour pressure deficit (VPD). Fruits grown under conditions of high R, W or VPD accumulate more Ca. The xylem/phloem mobility of Ca along with fruit morpho-anatomical features are evoked to explain this result. Orchard managements to increase fruit Ca via manipulations of the fruits’ aerial microenvironment are discussed.

Abstract
The paper summarises the effects of the common weather variables radiation (R), windspeed (W), air temperature (T) and relative humidity (RH) on fruit transpiration, and of fruit transpiration on fruit mineral accumulation (particularly calcium, Ca) in apricot and kiwifruit. The effects of T and RH on transpiration are combined in vapour pressure deficit (VPD). Fruits grown under conditions of high R, W or VPD accumulate more Ca. The xylem/phloem mobility of Ca along with fruit morpho-anatomical features are evoked to explain this result. Orchard managements to increase fruit Ca via manipulations of the fruits’ aerial microenvironment are discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
