Our researches seek to identify the main physiology traits conferring water deficit tolerance. 2002-2004 Non-governmental organization Agrarian Action The project was developed in Sandia, a rural and poor region in the south of Peru. We took actions to replace coca (Erythroxylum coca) with more profitable fruit crops. My function was to coordinate actions between regional authorities, technicians and farmer associations to foment fruit crops. - Adoption of fruit crops by most farmer associations, which

grouped some 400 farmers. - Training small farmers in modern techniques of fruit production in fruit crops such as granadilla (Passiflora ligularis), cherimoya (Annona cherimola), and avocado.

Integration of physiological methods to estimate water deficit in scions, clones, rootstocks and interstocks of 'Tahiti' acid lime In: Second International Citrus Biotechnology Symposium, 2009, Catania. RESEARCH EXPERIENCE • Role of rootstocks in drought tolerance of citrus plants: signaling, water

relations, photosynthesis, and growth: Climate change could trigger lack of water in several regions, decreasing plant productivity and threating food security. Researches to understand the physiology of plants under water stress will be important in the selection of superior materials of the breeding programs. At the beginning of the soil water deficiency, roots synthesize signals that induce stomatal closure to avoid excessive water loss. The signaling is, in this way, a key point to develop crops with high water use efficiency. The aim of this research was to assess chemical and hydraulic signals in drought tolerance of two citrus rootstocks. It was carried out two experiments: in the first, Valencia orange, Rangpur lime, and Swingle citrumelo seedlings were grown in partial root drying (PRD). PRD involves the irrigation of a portion of the root zone, leaving the rest of the root part to dry. In the second experiment, Valencia orange seedlings were inarching with Rangpur lime and Swingle citrumelo. We assessed water relations, leaf gas exchange,

hydraulic conductivity, growth, concentration of abscisic acid in leaves and sap, xylem sap pH, sap flow, and aquaporin activity.

• Influence of rootstocks on citrus vigor, physiological mechanisms: this research was conducted in 2010 in a Hamlin orange orchard at Saint Cloud, Florida, USA. Trees were planted in 1986, grafted on 32 different rootstocks, and never pruned resulting in high vigorous trees. Rootstocks were responsible for the difference in tree height. The aim of the research was to determine the involved mechanisms for rootstock effect on scion vigor. We measured height, architecture, xylem water potential, stomatal conductance, and water use efficiency.

• Economic viability of blueberry production (Vaccinium ssp.): Blueberry

demand is increasing worldwide driven by its nutraceutical and functional properties that neutralize the damaging effects of free radicals. Fruit harvest period in Brazil occurs off-season related to the main world producers like USA and European countries, leading to a price increase. Small farmers in Brazil are planting blueberries with difficulties and lack of information about the market and economic analysis in order to make the right decisions. The aim was to survey the establishing and production costs of blueberries in Erechim, RS, and, thereafter, to prepare the cash flow and calculate the financial indicators such as NPV, IRR, and payback. As a result, it was observed that the higher expenses were the investments in cooling chamber installation and seedling costs. The highest variable cost was hand labor at harvesting period. Financial indicators showed that blueberries production is highly profitable, NPV of R$ 397,270.75 and IRR of 22.56%. The payback period was 6.11 years.

• Rootstocks for Tahiti lime grown with and without irrigation: The worldwide citrus industry faces new challenges such as diseases emergence and socio-environmental demands from consumers. In this context, rootstocks diversification, irrigation, and high-density orchards are relevant. We evaluated the performance of Tahiti lime grown both with and without irrigation. Rootstocks influenced the tree vigor, especially the Flying Dragon trifoliate that decrease height in 47%, compared to Rangpur. Trees on vigorous rootstocks showed higher productivity and profitability when grown without irrigation. Trees on citradia 1708 showed high productivity and profitability both with and without irrigation. The interstock effect on the tree vigor was related to the rootstock.

• Development and yield of eight cultivars and hybrids of mandarins on

four rootstocks: This research assessed the horticultural performance of tangerine Fallglo, tangerine Swatow, tangor Ellendale, tangerine Fortune, tangelo Nova, tangerine Fairchild, tangerine Sunburst and tangerine Fremont grafted on Rangpur lime, Swingle citrumelo, Cleopatra mandarin, and Orlando tangelo. The experiment was carried out in São Paulo State and established in 1997. Trees on Orlando, Cleopatra and Rangpur rootstocks were more vigorous than those ones on Swingle. Fruits with higher soluble solids and

acidity were produced on Swingle citrumelo and Cleopatra mandarin representing good options to diversify rootstocks for tangerines.
