AB  - Partial root drying (PRD) is a new irrigation and growing plants technique which improves the water use efficiency without significant yield reduction. The aim of the presented paper was to investigate the effect of PRD on tomato plant growth, water-use efficiency (WUE) and ions content and distribution in tomato organs. Obtained results showed that as a consequence of PRD treatment the growth of the whole plants was reduced, but not fruit, although WUE was increased. Water potential values of PRD plants did not differ significantly from those of well-watered plants. These results support the hypothesis that a root-sourced signal and not a leaf-sourced signal may be responsible for triggering growth reduction in these PRD plants. Data for ions content (N, P, Ca, Mn, Zn and Cu) and their distribution between roots, shoots and fruits showed that PRD treatment only significantly changed N content in the shoots.

AB  - Introdution: Partial root drying (PRD) is a new irrigation and growing plants technique which improves the water use efficiency without significant yield reduction. Recent results showed that PRD may reduce plants vigour and increased the quality and yield of fruit (Davies et al., 2000; Loveys et al., 2000). The aim of presented paper was to investigate the effect of PRD on tomato plants growth, water-use efficiency (WUE), fruits yield and quality and ions content and distribution in tomato organs.
Material and Methods: Tomato plants were grown in a growth cabinet (light intensity 250μmol m-2 s-1, day/night temperature of 28/18˚C, relative humidity 70% and photoperiod 12h) in commercial compost with the root system divided equally between two plastic pots. For PRD treatment we repeated the Davies et al. (2000) experiment in such a way that during the vegetative and generative stages of tomato development, half of the root system of PRD was maintained in a dry state, while the remainder of the root system was watered. When soil water canted was reduced to 30 %, the treatment was reversed. In control plants both compartments were watered daily to drip point throughout the experimental period.
Results and Conclusions: Obtained results showed that as a consequence of PRD treatment the growth of whole plants was reduced, but not fruit, although WUE was increased. PRD results also demonstrated that obtained technique improved a quality of the fruits (by increasing total sugar content).Water potentials values of PRD plants did not differ significantly from those of well-watered plants. These results support the hypothesis that a root-sourced signal and not a leaf-sourced signal may be responsible for triggering growth reduction in these PRD plants. Data for ions content and distribution between roots, shoots and fruits showed small but significant treatment differences in the import by fruits of N, P and K (phloem mobile elements) and Ca (xylem mobile element). Obtained results suggest that with PRD technique we can halve the demand for irrigation water and increase the nutritional value of the tomato fruit.

AB  - An examination was made of the effect of partial root zone drying
(PRD) treatment on fruit growth of tomato plants, photosynthesis,
transpiration, water potential, activity of cell wall peroxidase, fruit
yield, sugars, lycopene minerals and dry weight. Pedicel vasculature
area and ion accumulation measurements were performed to
determine hydraulic implications for solute transport to fruit.
Plants were grown in compost with the root system equally divided
between two plastic pots. During the experimental period, half of the
root system of PRD plants was exposed to drought, while the
remainder was irrigated. After about 10 days, treatment was
reversed. Control plants received the same amount of water on
both sides of the root system. PRD treatment reduced the plant's
height, number of leaves and ¯ower trusses, but not fruit growth,
photosynthesis, ion content and pedicel vasculature. The effect on
stomata depended on the stage of plant development. PRD caused a
signi®cant increase in peroxidase activity and sugar content in
mature fruits and crop water-use ef®ciency. The effect of PRD
treatment on tomato fruit growth and biochemistry appeared not to
be mediated through greater hydraulic isolation of PRD fruits from
the vegetative parts of plants. Another physiological mechanism
must be considered for full understanding of the PRD effect.

AB  - Partial root drying (PRD) is a new irrigation and plants growing
technique which improves water use efficiency without significant yield reduction.
In the present paper some of the recent data concerning PRD effects
on crop plants are presented as well as some of our own results of PRD grown
tomato plants. Tomato plants (Lycopersicon esculentum Mill.) were grown
in commercial compost with the root system divided equally between two
plastic pots. During the vegetative and generative stage of development, half
of the root system of PRD was maintained in a dry state, while the remainder
of the root system was irrigated. After c.10 days (when soil water content
was reduced to 30%) the treatment was reversed, allowing the previously
well-watered side of the root system to dry down while fully irrigating the
previously dry side. Therefore, PRD plants received half of the amounts of
water used by plants in the control treatment. During the experimental period
the analyses of several plant growth and productivity and gas exchange parameters
were done. The results obtained showed that as a consequence of PRD
treatment the growth of whole plants was reduced with increased crop water
use efficiency and sugar content.
