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.
