Abstract

Water stress affected mycorrhizal infection
percentage of tomato plants subjected to a 72-hour-nonirrigated
period and their further recovery at 120 hours. However, the
relatively low colonization had a stimulatory effect on
inoculated plant growth, which was more effective on plant
top than in its root. Such a huge development was observed
on a larger leaf area, maybe due to a greater leaf carbohydrate
synthesis ratio. This performance was kept within the recovery
period. Developmental chages of mycorrhized plants were
associated to a higher stomatal opening and photosynthetic
activity together with a bigger root hudraulic conductivity.
Although a greater water potential was recorded on inoculated
stressed plants, compared to noninoculated ones, the absence
of a stressed-plant osmotic fit reduced leaf turgor over the
stressing period, that was recovered when irrigation was
renewed.
