ABSTRACT.
The reduced pool of the abscisic acid (ABA) precursors, ?-? carotenoids, in roots does not account for the substantial increase of ABA content in response to water stress (WS) conditions, suggesting that ABA could be transported from other organs. Basipetal transport was interrupted by stem-girdling and ABA levels were determined in roots after two cycles of WS induced by transplanting plants to dry perlite. Leaf applications of isotope-labelled ABA and reciprocal grafting of ABA-deficient tomato mutants were used to confirm the involvement of aerial organs on root ABA accumulation. Disruption of basipetal transport reduced ABA accumulation in roots and this decrease was more severe after two consecutive WS periods. This effect was linked to a sharp decrease in the ?-? carotenoid pool in roots in response to water deficit. Significant levels of isotope-labelled ABA were transported from leaves to roots, mainly in plants subjected to water dehydration. Furthermore, the use of different ABA-deficient tomato mutants in reciprocal grafting combinations with wild-type genotypes confirmed the involvement of aerial organs in the ABA accumulation in roots. In conclusion, accumulation of ABA in roots after long-term WS periods largely relies on the aerial organs suggesting a reduced ability of the roots to synthesize ABA from carotenoids. Furthermore, plants are able to basipetally transport ABA to sustain high hormone levels in roots.

Abstract:
Pear is a fruit of great importance for human nutrition due to the organoleptic characteristics and nutritional composition. Its cultivation in Uruguay generally uses rootstocks for adaptation to the soil, productiveness and precociousness, but rootstock selection may also influence fruit quality, with the ability to change its chemical composition. The objective of this work was to evaluate the influence of rootstocks on some physicochemical and nutritional compounds of 'Williams' pear, grafted on six rootstocks (EMC, BA29, OH×F333, OH×F40, OH×F69 and Adams) in Uruguayan production conditions. The experimental design was a randomized complete block design with four replicates located in an orchard at INIA-Las Brujas Experimental Station. At harvest, 20 fruits were sampled per replicate, conditioned in a cold chamber and then at room temperature until consumer maturation. Soluble solids content, titratable acidity, color and texture were evaluated and then fruit peel and pulp were separated for determination of ascorbic acid and minerals contents. As a result, in relation to the soluble solids, titratable acidity, color and texture, no differences were found between the rootstocks. For ascorbic acid content, no significant differences between rootstocks were found, but the concentration was higher in the fruit peel than pulp. The highest phosphorus content was found in the pulp, but calcium and magnesium contents were higher in the peel. The OH×F40 and OH×F69 rootstocks provided higher phosphorus and zinc contents and the boron content was higher in fruits of plants grafted on OH×F40 rootstock. As a conclusion, rootstocks influenced the nutritional content of 'Williams' pear fruits under Uruguayan cultivation conditions, which makes it possible to select a more convenient rootstock in terms of production and to contribute with a greater amount of nutrient in fruits.
