| Abstract:
The influence of two different water regimes on physiological, as well as quantity and quality parameters was studied in field grown processing tomatoes (Lycopersicon esculentum cv Brigate). In the first regime (TI1) irrigation requirements were determined using evapotranspiration calculations while in the second (TI2) irrigation was applied according to the cultural practice used in Greece. Results indicated that TI1 plants exhibited higher predawn leaf water potential values and higher diurnal values of stomatal conductance and transpiration rate. The number of fruit as well as marketable fruit yield was significantly higher in TI1 compared to TI2 plants. Generally quality characteristics were not significantly differentiated between the two treatments with only exception the total soluble solids content of the fruits which appeared to be higher in TI2 compared with the TI1 plants probably due to the lower yield and smaller size of fruits. | |
