Water scarcity can elicit drastic changes in plant metabolic and hormonal regulation, which may be of fundamental importance to stress tolerance. The study of plant the metabolic alterations in response to water deficit, especially the effects of the rootstocks level, is important to elucidate the mechanisms associated to drought tolerance. To verify the influence of rootstock and grafting on the tolerance to drought in citrus plants, we analyzed the growth, phytohormone levels and flavonoid profiles in grafted and ungrafted citrus plants subjected to different soil water regimes on plant status (well-watered, moderate drought and severe drought and rehydrated) under field conditions. The experiments were conducted under field conditions in the Brazilian Agricultural Research Corporation (EMBRAPA), Cruz das Almas, BA, Brazil. Water deficit reduced the total leaf area per plant in all canopy/rootstock combinations. Self-grafting reduce root volume, area and length when compared to ungrafted plants. Drought-induced increases in salicylic acid and abscisic acid associated with concomitant reductions in indoleacetic acid were observed in most canopy/rootstock combinations. However, plants with 'Sunki Maravilha' rootstocks exhibited the most pronounced changes in hormonal levels upon drought stress. Associated to these hormonal changes, drought also significantly affected flavonoid content and profile in both leaves and roots of the distinct citrus combinations. Glycosylated (GFs) and polimethoxylated flavonoids were predominantly found in leaves, whereas prenylated coumarins were found in the roots. Leaf levels of GFs (vicenin, F11, rutin and rhoifolin) were particularly modulated by drought in plants with 'Rangpur Santa Cruz' lime rootstock, whereas root levels of prenylated coumarins were most regulated by drought in plants with the 'Sunki Maravilha' root system. Taken together, these data indicate that the impacts of water deficit restriction on growth, hormonal balance and flavonoid profiles significantly varies depending on the canopy/rootstock combinations.
