Drought is one of the factors that most reduces crop productivity. Water deficit
affects the morphological and physiological parameters of the plant, and some
of them can be used as indicators of plant tolerance to drought. The aim of this
experiment was to evaluate the effects of water deficit on proline content in
fruits, as well as yield parameters of two tomato lines (M7 and R83), that in
previous research showed a contrasting response in vegetative phase. Tomato
plants were grown in a glasshouse in pots during three months after planting
of seedlings. Two water regimes were applied (optimal field capacity and water
deficit - reduction of water for 30% compared to control). The content of
proline was significantly higher in the fruits of both tomato lines exposed to
water stress. The increase in proline content under stress conditions compared
to control was higher in fruits of line M7 (81.0%) compared to line R83
(35.4%). Our results showed that water deficit significa...ntly affected fruit
diameter, length and biomass of the fruit, but did not affect the number of fruits
per plant in both tested tomato lines. The reduction of fruit yield in water deficit
conditions was higher for line M7 (31.5%) in comparison to line R83 (20.7%).
Based on the obtained results, the R83 line showed a potentially better response
to drought stress at fruit level, which is in accordance with our research results
conducted on the same lines in the vegetative phase.
