“…The reaction of plants under conditions of increasing drought was significantly weaker (Figure 2). The results are consistent with the results of previous studies whereby a temperature higher than optimal intensified development of the aboveground part of plants (Rykaczewska 2013b(Rykaczewska , 2015. Heat stress under drought conditions negatively influenced PI activity in the tested plants.…”

Potato (Solanum tuberosum L.) is a plant typical mainly for temperate climate and develops best at about 20°C. Heat stress due to increased temperatures is an agricultural problem in many areas in the world. The aim of our work was to assess the response of selected new potato cultivars to heat and drought stress during the subsequent stages of plant growth starting from buds forming. The pot experiment was carried out over the course of two years with the following early cultivars: Lord, Miłek, Gwiazda, Hubal, Oberon and Tetyda. The impact of heat (38°C/25°C) and drought stress on potato plants was tested in four periods of two weeks. In these periods half of the plants were watered to a level close to optimal while the other half remained without irrigation. Our studies demonstrated that tested potato cultivars’ response to heat stress depends on the growth stage, in which the temperature acts on the plants and on the soil moisture. Besides the decrease in yield and tubers’ diminution, the biggest problem was the presence of tubers with physiological defects, particularly of immature tubers. The response of cultivars was differentiated.

“…In the control there were no the tubers with physiological defects. Results of the experiment obtained by Rykaczewska (2013b) are similar. However, Levy (1985) show that a single treatment of high temperatures during early stages of tuber development caused a lower percentage of misshapen tubers.…”

“…In subsequent studies large differences among cultivar susceptibility to secondary tuberization due to the impact of high temperature (32°C/ 25°C) during the growing season were demonstrated (Rykaczewska 2013b). In the study presented here a highly significant effect of the period of high temperature and cultivar on the tuber size in the yield was also found (Table 3, 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...

“…It is connected with the fact that temperature higher than optimal intensified development of the aboveground part of plants and tuberisation is significantly inhibited (Lafta and Lorenzen 1995). This is confirmed by the results of our previous studies, where it was found that under higher temperature the plants of all cultivars responded with an increase in height (Rykaczewska 2013(Rykaczewska , 2015.…”
