“…These findings are inconsistent with those of Kaemmerer et al (2007). They demonstrated that the intensity of infection in leaves and tubers was similar, and even much higher in leaves in the initial part of the growing season.…”

The aim of research was to evaluate an effect of weather conditions in the years of study considering the air temperature and precipitation as well as granulometric distribution of soil, taking into account the temperature and moisture content, on asymptomatic infection caused by Clavibacter michiganensis subsp. sepedonicus (Cms) in leaves and tubers. The level of infection of leaves and tubers with Cms was differentiated by the thermal and humidity conditions occurring in the years of research. The granulometric distribution of soil (soil profile) had a significant effect on the level of leaf infection. In the year 2014, with moderate temperature and humidity, the highest intensity of leaves and tubers infection was observed on soil of the highest moisture content -sandy loam. In the years with extreme weather conditions, i.e. the drought in 2015 or the abundant rainfall in 2016, the most intensive infection was observed in leaves and tubers grown on soil of low humidity -slightly loamy sand and loamy sand. The degree of infection was found to decrease with increasing air temperature and precipitation level as well as with the increase of soil moisture. On the other hand, increasing soil temperature favoured infection in tubers. ResumenEl objetivo de esta investigación fue evaluar el efecto de las condiciones meteorológicas en los años de estudio, considerando la temperatura del aire y la precipitación, así como la distribución granulométrica del suelo, tomando en cuenta la temperatura y el contenido de humedad, en la infección asintomática causada por Clavivacter michiganensis subesp. Sepedonicus (Cms) en hojas y tubérculos. El nivel de infección de las hojas y los tubérculos con Cms se diferenció por las condiciones térmicas y de humedad que se presentaron en los años de la investigación. La distribución granulométrica del suelo (perfil del suelo) tuvo un efecto significativo en el nivel de infección foliar. En el año 2014, con moderada temperatura y humedad, la más alta intensidad de infección de hojas y tubérculo se observó en suelo con el contenido de humedad más alto, franco arenoso. En los años con las condiciones meteorológicas extremas, i. e., la sequía en 2015, o la lluvia abundante en 2016, la infección más intensiva se observó en hojas y tubérculos cultivados en suelo de baja humedad, ligeramente areno-arcilloso y areno-arcilloso. El grado de infección se encontró que disminuía con el aumento de la temperatura del aire y el nivel de precipitación, así como con el incremento de humedad del suelo. Por otro lado, al aumentar la temperatura del suelo se favorecía la infección en los tubérculos.

“…Other cultivars were characterized by a high level of leaf and tuber infection (except for 'Innovator'-medium level of cell concentration in tubers). Kaemmerer et al (2007) also reported that 20% of tubers derived from plants with higher infection and stored for 4 months showed typical disease symptoms. The number of bacteria detected with the IFAS test in tuber samples stored until spring did not change significantly.…”

“…Analysis of symptoms in tubers made after harvest (autumn), during 4 years of research, revealed a total of 40 tubers with typical changes in vascular bundles. According to Kaemmerer et al (2007), the size of bacterial population in the aboveground parts and tubers of plants is a factor affecting the occurrence of infection, symptom expression and potato yield. These researchers found that the symptoms appear on leaves and in progeny tubers only with a higher bacterial concentration in the plant.…”

Latent Infection by Clavibacter sepedonicus and Correlation with Ring Rot Symptoms Development in Potato Cultivars

The aim of this study was to determine the response of potato cultivars to Clavibacter sepedonicus (Cs) infection in a field experiment. The research focused on the infection in a latent form as it is a risk for unnoticed spread. A total of 18 cultivars were tested in the years 2013–2016. Symptoms of the disease were observed on the leaves during growth and in tubers after harvest and after storage. The infection incidence was determined by microscopic observation of leaf and tuber samples stained by the IFAS method. A diverse response of potato cultivars to Cs infection was found. The lowest number of asymptomatic infected plants was found in cultivars ‘Vineta’, ‘Bila’ and ‘Irga’. As for cultivar ‘Stasia’, the entire tuber yield was latently infected by Cs. A low or medium concentration of Cs cells in leaves did not change significantly or increased depending on the potato cultivar. A higher incidence of tubers with disease symptoms was found after the storage period. In eight of the cultivars tested, the level of tuber infection by Cs confirmed microscopically after harvest was significantly correlated with the occurrence of disease symptoms in tubers after the storage period.

“…Correlations of the influence of climatic factors on the development of Cs bacteria in the plant were undertaken by Kaemmerer et al (2007). In the years 2002-2004, the researchers carried out field studies, during which they found significantly higher tuber and stem base infection in the mid-early Agria variety in the year with very high temperature and low humidity.…”

“…While the practice of cutting seed potatoes is common in North America, in Europe the practice of cutting seeds before planting is increasingly rare and unacceptable with the current state of knowledge (Van der Wolf et al 2005;Nolte et al 2020). The influence of the weather conditions on the occurrence and intensity of symptoms on leaves and in the tuber yield is constantly being addressed (Logdson 1967;Paquin and Genereux 1976;Bishop and Slack 1987a, b;Hukkanen et al 2005;Kaemmerer et al 2007;Hill et al 2011). So far, the study results have not given a clear answer to questions about the interaction between the pathogen, the plant and the environment.…”

Reaction of selected potato varieties to Clavibacter sepedonicus infestation under changing weather conditions

et al. 2021

The results of the studies carried out over the last 50 years have not provided a clear answer to questions concerning the interaction between Clavibacter sepedonicus (Cs), potato and the environment. The reason is insufficient knowledge of the biology of the causal agent of ring rot, problems of research methodology and the influence of many environmental and biotic factors on the degree of plant infestation. The research conducted in the years 2013–2016 in the Plant Breeding and Acclimatization Institute – National Research Institute concerned the determination of the influence of weather conditions, involved the influence of temperature and Sielianinov hydrothermal coefficient on the development of Cs bacteria in stems and progeny tubers, as well as the occurrence of disease symptoms on plants and in tubers of eight potato varieties. It was found that genotype had the greatest impact on leaf and tuber infestation, while weather conditions were less significant. The results of correlation analysis indicate that the weight of tubers of plants infected by Cs increased statistically significantly with increases in air and soil temperature. On the other hand, air and soil temperature in the initial vegetation period did not significantly affect the number of potato plant tubers infested by Cs. In a 4-year experiment, it was not shown how air and soil temperature and the Sielianinov hydrothermal coefficient affected the degree of potato leaf and tuber infestation. In most cases, potato infestation by Cs caused a decrease in yield.
