“…Results from correlation studies between tuber resistance and resistance to blackleg in the field have not been described before, although some groups have reported on the relation between tuber resistance and blackleg of glasshouse grown plants. Thus Zadina and Dobifi~ [1976] found a correlation coefficient of 0.65 after screening 198 cultivars for resistance to Eca, in contrast to the work by Munzert and Hunnius [1980] and Hidalgo and Echandi [1982] who found no correlation for Eca and Ech respectively. The absence of a correlation can partly be explained by changes in relative tuber tissue resistance after planting in the field (Table 6) which was in contrast to the good reproducibility found for tuber tissue resistance when using tubers stored for various lengths of time, especially after inoculation with Eca [Allefs et al, 1995].…”

“…Breeding for resistance to blackleg may contribute both to a reduction of the probIem for seed producers and ware potato growers. Genetic variation for resistance has been identified both in cultivated Solanum tuberosum [Zadina and Dobifi~, 1976;Hidalgo and Echandi, 1982] and in species of the Solanum section petota [Soest, 1983;Lojkowska and Kelman, 1989].…”

“…Methods are only suitable if they are easy to perform, applicable to early vegetative generations and yield reproducible and quantitative data that show good agreement with the resistance of the clones in farmers' fields. Numerous methods for screening of plants in the field [Hossain and Logan, 1983;Lapwood and Legg, 1983;Lapwood and Gans, 1984;Lapwood and Read, 1986a;Gans et al, 1991], or in the glasshouse [Munzert, 1975;Hidalgo and Echandi, 1982;Lapwood and Read, 1986b;Lojkowska and Kelman, 1989] have been described. Field tests correspond most to field conditions but they are expensive to perform and not feasible when only a small amount of seed is available.…”

In t991 and 1992, 12 potato cultivars were screened at two locations for resistance to blackleg, after vacuum infiltration of the seed with Erwinia carotovora subsp, atroseptica or E. chrysanthemi. Cultivar differences for resistance to E.c. subsp, atroseptica and E. chrysanthemi were found which were consistent over locations and years. Seed tubers of the same cultivars were also screened for resistance to both Erwinia spp. by using a tuber slice inoculation method. Correlation coefficients for comparisons between resistance to blackleg in the field and tuber tissue resistance under aerobic or anaerobic conditions were not significant. This could partly be explained by drastic changes in relative tuber tissue resistance of the cultivars within a 5 weeks period after planting in the field. Presprouting of seed tubers in diffuse daylight had a less pronounced effect on relative tuber tissue resistance than planting in the field. Monitoring the process of mother tuber decay during the growing season of 1993 after vacuum infiltration with E.c. subsp, atroseptica and E. chrysanthemi revealed that cultivars differed in the extent to which these bacteria enhanced the process of mother tuber decay. These differences partly explained the cultivar differences for resistance to blackleg in the field.Abbreviations: Eca = Erwinia carotovora subsp, atroseptica; Ech = Erwinia chrysanthemi; NOP = Noordoostpolder; Wag --Wageningen

Essas bactérias são de ocorrência endêmica em todas as áreas em que a batata é cultivada, sendo o controle baseado principalmente no manejo integrado, que inclui, como medidas mais importantes uso de sementes sadias, erradicação de plantas com sintomas, rotação de culturas e cultivares resistentes, embora esta última seja fortemente influenciada por condições ambientais (Hidalgo & Echandi, 1982;Lyon, 1989;Bdliya, 1995;Walters & Collins, 1995).…”

Ação do acibenzolar-S-metil aplicado em tubérculos e plantas de batata contra canela preta, incitada por Pectobacterium carotovorum subsp. atrosepticum atípica

A resistência sistêmica adquirida (SAR = systemic acquired resistance) é um importante mecanismo de resistência a doenças em plantas. Neste estudo, a ação do acibenzolar-S-metil (ASM), derivado benzotidiazólico ativador de resistência em plantas foi avaliada sobre a brotação de tubérculos de batata (Solanum tuberosum) e quanto à ação deste na indução de resistência à canela-preta, incitada por Pectobacterium carotovorum subsp. atrosepticum atípica (Pcaa), nas cultivares Asterix, Baronesa e Monalisa. Nas doses, 60, 120, 150, 200 e 250 mg i.a. l -1, o produto não inibiu o número de brotos. Contudo, em concentrações mais elevadas influenciou o comprimento destes. Em casa de vegetação, nas concentrações de 60 e 120 mg i.a. l -1 ASM, tanto no tratamento de tubérculos quanto no de aspersão nas plantas, a cultivar Asterix, respondeu ao tratamento do ASM, conferindo-lhe resistência à canela preta. Na cultivar Baronesa, a resposta ao ASM ocorreu somente no tratamento de tubérculos, e, para a cultivar Monalisa, não houve resposta ao ASM. Verifica-se, neste estudo, que houve ação do ASM sobre a indução de resistência e que este foi específico para determinadas cultivares de batata.

Both tubers and plants of potato were successfully inoculated with Erwinia carotovora subsp. itroseptica by means of a needle‐less medical jet injector. The instrument has also been used to infect potato tubers with Phorna exigua var. foveata, Fusarium solani var. coeruleum and F. sulphureum. It is suggested that high‐pressure injection is a potentially useful tool for introducing pathogens into plant materials.
