ABSTRACT.
lant domestication by selective breeding may reduce plant chemical defense in favor of growth. However, few studies have simultaneously studied the defensive chemistry of cultivated plants and their wild congeners in connection to herbivore susceptibility. We compared the constitutive glycoalkaloids (GAs) of cultivated potato, Solanum tuberosum, and a wild congener, S. commersonii, by liquid chromatography coupled to mass spectrometry. We also determined the major herbivores present on the two species in field plots, and tested their preference for the plants and their isolated GAs in two-choice bioassays. Solanum commersonii
had a different GA profile and higher concentrations than S. tuberosum. In the field, S. tuberosum was mostly attacked by the generalist aphids Myzus persicae and Macrosiphum euphorbiae, and by the specialist flea beetle Epitrix argentinensis. In contrast, the most common herbivore on S. commersonii was the specialist sawfly Tequus sp. Defoliation levels were higher on the wild species, probably due to the chewing feeding behavior of Tequus sp. As seen in the field, M. persicae and E. argentinensis preferred leaf disks of the cultivated plant, while Tequus sp. preferred those of the wild one. Congruently, GAs from S. commersonii were
avoided by M. persicae and preferred by Tequus sp. The potato aphid performed well on both species and was not deterred by S. commersonii GAs. These observations suggest that different GA profiles explain the feeding preferences of the different herbivores, and that domestication has altered the defensive capacity of S. tuberosum. However, the wild relative is still subject to severe defoliation by a specialist herbivore that may cue on the GAs.

ABSTRACT:
The objective of this experiment was to evaluate the application of different values of maximum crop evapotranspiration as irrigation trigger on maize growth. The experiment was conducted during the 2000/2001 growing season in the experimental field of the Agricultura) Engineering Department of the Federal University of Santa Maria, RS-BRAZIL. A set of 24 drainage lysimeters was used. The experimental site was protected against rainfall by a mobile arch rainshelter. Maize plants were submitted to five irrigated treatments. Irrigation 's were applied when cumulative daily maximum .crop evapotranspiration (ETmc), estimated by the Penman-Monteith equation, reached values of 14, 22, 30, 38 and 46 mm. A completely randomized design was used with four replications. Results demonstrated that there were no differences for leaf area indet. Use of the irrigation water management of 34 mm of ETmc resulted in higher plants.

O experimento foi conduzido no delineamento experimental inteiramente casualizado, com quatro repeti\:5es. As plantas de milho foram submetidas a cinco manejos da água de irriga\:ao. Irriga\:5es foram aplicadas sempre que a evapotranspira\:ao máxima da cultura acumulada (ETma) estimada pelo método de Penman-Monteith alcan\:ava valores de 14, 22, 30, 38 e 46 mm.
