Long-term graft compatibility study of peach-almond hybrid and plum based rootstocks budded with European and Japanese plums
23 Pags.- 3 Tabls.- 4 Figs. The definitive version is available at: https://www.sciencedirect.com/science/journal/03044238The introduction of some new rootstocks requires knowledge of the potential âtranslocatedâ and âlocalizedâ graft incompatibilities before releasing these rootstocks into the market. Trials were established at the Aula Dei Experimental Station (Zaragoza, Spain) to assess graft compatibility between five European plum (Prunus domestica L.) and six Japanese plum (Prunus salicina L.) cultivars with thirty-eight rootstocks belonging to peachâĂâalmond hybrids, as well as slow-growing, fast-growing and interspecific hybrid plum groups. Some of these rootstocks are under process of selection and others are commercial rootstocks already introduced into the European market. External visual diagnosis of the scion-rootstock graft combinations was performed by observing symptoms of the âtranslocatedâ incompatibility in the nursery. Visual symptoms of âtranslocatedâ incompatibility were only found on the Japanese plum cv. âGolden Japanâ budded on the plum-apricot hybrid AP-45. The âlocalizedâ graft incompatibility was assessed after internal macroscopically examination of graft unions. In the case of the European plum cvs., âPresidentâ and âReine Claude Tardive of Chambourcyâ exhibited good graft compatibility with all the tested rootstocks, with the exception of âPresidentâ budded on the pentaploid plum hybrid rootstock Damas GF 1869. âReine Claude Verteâ cv. showed âlocalizedâ incompatibility with Myrobalan B and Myrobalan GF 3-1 since the second year after budding. âStanleyâ cv. showed âlocalizedâ incompatibility with the six evaluated peachâĂâalmond hybrid rootstocks, although it was compatible with all plum based rootstocks. In the case of Japanese plums, four cultivars (âAngelenoâ, âBlack Amberâ,â Delbarazurâ and âSongoldâ) did not show any graft incompatibility, but âFriarâ showed âlocalizedâ incompatibility on Myrobalan B. In the case of peach-almond and P. cerasifera based rootstocks (Adarcias, GF 677, Damas GF 1869, Myrobalan B, Myrobalan 29 C, Myrobalan GF 3-1 and Marianna GF 8-1), âGolden Japanâ trees showed similar symptoms to those caused by TomRV in Myrobalan and peach rootstocks and âlocalizedâ incompatibility. Finally, this study confirmed the interest of P. insititia specie as well as several interspecific Prunus hybrids as a good source of rootstocks for the plum industry.Financial support was provided by the Spanish Ministry of Economy, Industry and Competitiveness (MINECO) grants CDTI IDEI-20130949, AGL2011-24576 and AGL2014-52063-R, and was co-funded by the FEDER and the Regional Government of AragĂłn (A44). G. Reig and C. Font i Forcada were supported by the Spanish Ministry of Economy, Industry and Competitiveness (MINECO) and Consejo Superior de Investigaciones CientĂficas (CSIC). O. Zarrouk was supported by a fellowship from the Spanish Agency for International Cooperation (AECI). A. Salazar was supported by a fellowship from the Secretary of Education, Science and Technology (SENESCYT) of the Ecuadorian Government.Peer reviewe
