“…The results of an experiment conducted by Bodlaender et al (1964) also clearly show that high temperatures induce second-growth in potato tubers. In the case of sprouting tubers in the soil before harvest, the response of plants to high temperature was also significantly dependent on treatment time but the biggest negative impact had a place when high-temperature stress was applied in the III period (the second part of July) (Fig.…”

“…Soil moisture had no significant effect. Similarly, according to Bodlaender et al (1964) high temperature can 'break' dormancy and drought did not induce or promote sprouting. In our experiment the reaction of cultivars was differentiated.…”

“…Here we show that soil moisture favourable for plants led to an increase of the number of tubers. However, the experiment conducted by Bodlaender et al (1964) showed that high temperature induces second-growth in potato tubers irrespective of the water supply and that drought is not necessary to induce the secondgrowth. In our experiment the largest increases in the number Fig.…”

Potato (Solanum tuberosum L.) is characterized by specific temperature requirements and develops best at about 20°C. High temperatures during the growing season cause an array of changes in potato plants, which affect its development and may lead to a drastic reduction in economic yield. In natural conditions drought and heat stress are two different types of abiotic stresses that occur in the field simultaneously or separately, in the case of irrigation use on potato plantations. The aim of this work was to assess the response of six potato cultivars to high temperature during the subsequent stages of plant growth under conditions of good soil moisture and drought. The pot experiment was carried out with the cultivars: Aruba, Desirée, Etola, Finezja, Flaming and Tetyda. The impact of high temperature day/ night 35°C/25°C on potato plants was tested in three periods: June 16-30, July 1-15 and July 16-30. In these periods half of the plants were watered to a level close to optimal, while the other half remained without irrigation. Final harvest was performed after full maturity of plants in the control combination. Our studies confirm the view that potato productivity is greatly reduced at temperatures higher than optimum. Here we demonstrated that tested potato cultivar's response to high temperature during the growing season is dependent on the growth stage. The earlier a heat occurs, the more negative its impact on the growth and total yield of potatoes. The results obtained in this study indicate that among the tested cultivars 'Tetyda' was the most tolerant to high temperature acting on the plants during the growing season. Our research shows that the total yield is not the only indicator of potato tolerance to high temperature during the growing season, but the assessment should also take into account the occurrence of secondary tuberization and physiological defects of tubers.Resumen La papa (Solanum tuberosum L.) se caracteriza por requerimientos específicos de temperatura y se desarrolla mejor a cerca de 20°C. Las altas temperaturas durante el ciclo del cultivo causa un arreglo de cambios en las plantas, que afecta su desarrollo y pudiera conducir a reducción drástica en el rendimiento económico. En condiciones naturales la sequía y el agobio térmico son dos tipos diferentes de agobios abióticos que se presentan en el campo simultáneamente o por separado, en el caso de siembras de papa de riego. El propósito de este trabajo fue evaluar la respuesta de seis variedades de papa a la alta temperatura durante los estados subsecuentes de crecimiento de la planta bajo condiciones de buena humedad del suelo y bajo sequía. El experimento en macetas se desarrolló con las variedades Aruba, Desirée, Etola, Finezja, Flaming y Tetyda. Se probó el impacto de la alta temperatura día/noche 35°C/25°C en plantas de papa en tres períodos: junio 16-30, julio 1-15 y julio 16-30. En estos lapsos la mitad de las plantas se regaron a un nivel cercano a lo óptimo, mientras que la otra mitad permaneció sin riego. La cosec...

“…Besides day length, temperature has a strong impact on tuber development. High temperatures during the growing season not only have negative effects on tuber formation and tuber dry matter accumulation, but also cause tuber chain formation, secondary growth and premature sprouting (Bodlaender et al 1964;Levy and Veilleux 2007). Heat stress during tuber maturation is thought to interfere with the onset of dormancy; the stolon tips resume growth and can form a second tuber under favourable conditions, e.g.…”
