Effect of moderate water deficit on biochemical and physiological parameters of tomato leaves and fruits
Apstrakt
Drought affected growth and productivity of vegetables by inducing different changes in
plants, which consequently reduces the yield and its quality. The aim of this work was to evaluate
the effect of moderate drought stress on physiological and biochemical parameters of the cultivated
tomato genotype Stupicke. Plants were grown in the greenhouse and exposed to water
deficit from anthesis of 2nd flower truss until fruit harvesting (red-ripe stage). Control plants were
optimally irrigated, while treated plants were exposed to drought and soil humidity was maintained
around 25% of maximum WHC. Drought-induced reduction of leaf growth parameters was
followed by changes in stomata conductance and photochemical efficiency. The results of biochemical
analysis indicated that the soluble sugar content decreased under drought conditions,
while organic acid level and vitamin C was increased. The significant decrease in fruit diameter
and dry matter content was accompanied with stable s...ugars and organic acid content which implicates
the maintenance of main fruit taste components under water deficit. The drought also affected
the level of other important nutritional components by the increase of the total carotenoid
and vitamin C content. Accumulation of the vitamin C in leaves and fruits are also a response
to secondary, oxidative stress under prolonged drought, while the increase of ABA content in
both organs is related to drought adaptive responses. These results indicated the potential of this
genotype for breeding programs to create new drought-resistant tomato lines with the stable or
improved nutritional fruit quality under variable environmental conditions.
