“…This is because attention has been paid mainly to biotic stresses, and only the high-value pepper transplants utilized for protected cultivations are produced as grafted plants [39,140,141]. However, the abiotic stress incidence is very high, and increasing global climate change is forecast, while salinity and water stress are found frequently in areas where peppers are growing.…”

Pepper is an extremely important vegetable worldwide in socio-economic terms. However, persistent land use, monoculture, and intensified production processes have led to soil diseases. This, along with abiotic stress, and mainly salinity of soil and waters, water stress, and suboptimal temperatures, can lead to physiological disorders emerging in peppers, e.g., cracking and Blossom end rot, which induce plant senescence, and lower not only in yields, but also in product quality. Salinity and water shortage are the two main environmental problems that crops face in the Mediterranean Region. One way of overcoming stresses from an ecological or integrated crop management viewpoint is to use grafted plants as an adaptation strategy. Initially, grafting technology has expanded in Solanaceae and Cucurbitacea species to overcome biotic stress. Nowadays, grafts are being used as several approaches to cushion the impact of climate change on agricultural systems. Furthermore, grafts allow desirable varieties by organoleptic or productivity traits, but they are sensitive to abiotic stress and can be grown under abiotic stress. As far as we know, very few studies on grafted pepper plants under abiotic stress are available.

“…Santos (2001), no Brasil, ao enxertar os híbridos comerciais de pimentão Elisa, Magali-R e Margarita com os porta-enxertos de pimenta AF-2638 e AF-2640, resistentes a Phytophthora capsici e M. incognita, verificaram de 88 a 100% de "pegamento" de plantas e, Choe et al (1985), na Coréia, ao enxertarem a cultivar comercial de pimentão 'Bulam-House-Putgochu' com linhagens e cultivares de pimentão resistentes a P. capsici, verificaram, em média, 93% de "pegamento" de plantas. Melo et al (2005) na tentativa de adaptar a metodologia de enxertia de pimentão em pimentas, utilizando como porta-enxerto a Linhagem CNPH 148 (C. annuum) resistente a P. capsici, para os genótipos de pimenta C. baccatum, C. chinense e C. frutescens, obtiveram de 60 a 100% de "pegamento" de plantas.…”

“…Santos & Goto (2004), ao avaliarem plantas de pimentão enxertadas, concluíram que a técnica da enxertia é viável no controle da murcha de P. capsici em ambiente protegido. Todavia, a procura de porta-enxertos com boas características, bem como a investigação de melhores combinações, deve ser uma constante, para, assim, poder otimizar os resultados do emprego da enxertia em hortaliças (Santos, 2001).…”

RESUMOAvaliou-se a resistência à Meloidogyne incognita e a compatibilidade de enxertia de treze porta-enxertos de pimenta (nove Capsicum chinense; três C. annuum e um C. frutescens) quando enxertados com os híbridos de pimentão-vermelho Rubia R, Margarita e Maximos. O experimento foi conduzido em 2005 na UNESP-FCAV em Jaboticabal-SP. As plantas foram enxertadas por garfagem do tipo fenda simples e, 25 dias após foram avaliadas quanto à percentagem de "pegamento" e, posteriormente, juntamente com plantas sem enxertia, foram transplantadas em casa de vegetação e inoculadas, individualmente, com 5.000 ovos e juvenis de segundo estádio de M. incognita. A avaliação da resistência dos porta-enxertos ao nematóide foi feita aos 181 dias após a inoculação, com base no fator de reprodução; a avaliação da compatibilidade enxerto/portaenxerto foi realizada levando em consideração a produtividade e a qualidade dos frutos obtidas em sete colheitas, realizadas entre 113 e 181 dias após o transplante das mudas. Aos 25 dias após a enxertia, para todos os tratamentos, em média, 99,69% das plantas enxertadas apresentavam-se com "pegamento". Os porta-enxertos C. annuum e C. frutescens, ao final do ciclo de cultivo, foram resistentes à M. incognita e proporcionaram nas plantas enxertadas, respectivamente, as maiores e menores produtividades e qualidades de frutos, sendo designados de compatíveis e incompatível para enxertia com os híbridos de pimentão-vermelho Rubia R, Margarita e Maximos. 'Maximos' e 'Margarita' quando enxertados apresentaram melhor produtividade e qualidade de frutos do que 'Rubia R'; quando sem enxertia não diferiram em produtividade, havendo destaque para 'Margarita' quanto à qualidade dos frutos.Palavras-chave: Capsicum spp., Meloidogyne spp., enxertia, cultivo protegido. ABSTRACT Hot peppers resistance to root-knot-nematodes and stump/ rootstock compatibility among hot peppers and red pepper hybridsThe resistance to Meloidogyne incognita and propagation compatibility of thirteen pepper rootstocks (nine Capsicum chinense; three C. annuum and one C. frutescens) were evaluated under Rubia R, Margarita and Maximos red pepper hybrids grafting. The experiment was carried out in 2005, in Jaboticabal, São Paulo State. Plants were cleft and notch grafted and, 25 days later, the pant surviving was evaluated. Later, the grafted plants and plants without stump were transplanted to a greenhouse and inoculated, individually, with 5,000 eggs and infants in the second phase of M. incognita. The rootstock resistance to nematodes was evaluated at 181 days after inoculation, based on the reproduction factor. The stump/rootstocks compatibility was evaluated considering yield and quality of fruits obtained through seven harvests, 113 to 181 days after seedling transplant. An average of 99,69% of surviving plants was obtained, 25 days after grafting date. The C. annuum and C. frutescens rootstocks were resistant to M. incognita at the end of the vegetative cycle and they provided to grafted plants the higher and lower fruit product...

“…The primary reason for grafting pepper is to increase plant vigour, uniformity and disease tolerance, but very few commercial pepper rootstocks are available because attention has been mainly paid to biotic stresses, and only high value pepper transplants used for protected cultivations are produced as grafted plants ( Oka et al, 2004;Santos and Goto, 2004). …”

Noviembre 2015 Programa de Doctorado en Recursos y Tecnologías Agrarias I | SUMMARYPepper is a vegetable of extraordinary economic and social importance in our country. Unfortunately, the persistent exploitation of the land, the monoculture and the intensification of production processes, lead to the development of soil diseases. This coupled with the abiotic stress, mainly the salinity of waters and soil, suboptimal temperatures and water stress, can induce the appearance of physiological disorders in peppers as the Blossom-end rot (BER) and cracking or cracked, induce plant senescence and decrease not only production, but also the quality of the product. Salinity and water shortages are two among the biggest environmental problems that crops have to face in the Mediterranean area. A way to overcome the stresses under the prism of an ecological or integrated crop management, is the use of grafted plants as adaptation strategy. Although there has been remarkable progress in this technique (mainly in tomato, melon, watermelon), in the cultivation of pepper use remains rare. In this Doctoral thesis several pepper genotypes have been selected through different physiological parameters which indicate tolerance to salt and water stress. Commercial cultivars were grafted onto the selected genotypes and were grown under water stress, salinity and control conditions studying several physiological, agronomic responses and the interaction rootstock/scion.The results obtained concluded that genotypes selected and used as rootstocks improved commercial varieties to salt and water stress tolerance, both in terms of performance (commercial production) compared to other commercial characters and variety without grafting. Different physiological mechanisms explain the tolerance to stress, such as the ability to maintain the water potential through an osmotic adjustment, stimulation of the antioxidant system, exclusion II | or retention of toxic ions (Na + and Cl -) in saline in the roots and the maintenance of photosynthesis which allows to maintain the metabolic functions of grafted plants and production. III | RESUMENEl pimiento es una hortaliza de extraordinaria importancia económica y social en nuestro país. Lamentablemente, la persistente explotación del suelo, el monocultivo y la intensificación de los procesos de producción, conducen al desarrollo de enfermedades del suelo. Esto unido a los estreses abióticos, principalmente la salinidad de las aguas y del suelo, temperaturas subóptimas y estrés hídrico, puede inducir la aparición de fisiopatias en el pimiento como el Blossom-end rot (BER) y cracking o rajado, inducir senescencia vegetal y disminuir no solo la producción, sino también la calidad del producto.La salinidad y la escasez de agua son unos los mayores problemas medio ambientales a los que tienen que hacer frente los cultivos en el área Mediterránea. Un modo de sortear los estreses bajo el prisma de un manejo integrado o ecológico del cultivo, es la utilización de plantas injertadas como estrategia de adaptació...
