Internal heat necrosis (IHN) is a physiological disorder resulting in necrotic tissue in the pith of potato (Solanum spp.) tubers. Susceptibility is associated with localized Ca deficiency within the tuber, but Ca availability may be influenced by other nutrients. Studies in Virginia, North Carolina, and New Jersey in 2001 and 2002 determined the influence of soil‐applied Ca on tuber yield, specific gravity (SG), IHN, and nutrient concentration. Furrow‐applied Ca sulfate (448 kg ha−1 Ca) was applied to IHN resistant or susceptible interspecific 4×–2× S. tuberosum L. (tbr) × S. phureja Juz. & Bukasov–S. stenotomum Juz. & Bukasov hybrids. Tuber yield, SG, incidence and severity of IHN, and pith concentrations of P, K, Mg, Ca, S, Na, Zn, Mn, Cu, and Fe were determined. Clones differed significantly for yield, SG, and IHN expression. Resistant clones were lower in IHN incidence than susceptible clones, but the clone × Ca interaction was not consistently significant within location–years. Incidence was fit with a classification and regression tree (CART) model with the 10 nutrients as regressors, which revealed that IHN‐resistant clones had higher tuber concentrations of Mn and S, but lower P. These results suggest that resistance or susceptibility to IHN is a complex function of tuber tissue mineral status. Mn, S, and P may make a more important contribution to clonal IHN resistance than Ca. Additional work is needed to verify the potential for minimizing IHN by either nutrient management or genetic enhancement.

“…From experiments conducted in growth chambers it is known that haulm growth is fastest in the temperature range of 20-25°C whereas the optimal range for tuberization and tuber growth is 15-20°C. Under hightemperature conditions, tuberization is significantly inhibited and photoassimilate partitioning to tubers is greatly reduced (Ewing 1981;Haynes et al 1989;Krauss and Marschner 1984;Lafta and Lorenzen 1995). Heat stress due to increased temperature is an agricultural problem in many areas in the world (Birch et al 2012).…”

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...

“…However, potato is a cool-season crop with an optimal temperature for tuber growth at ≈ 20 ° C (Ewing 1981). High temperatures result in a decrease in dry matter accumulation in tubers (Haynes, Haynes & Henderson 1989;Gawronska, Thornton & Dwelle 1992;Malik et al . 1992;Lafta & Lorenzen 1995).…”

We have examined the ability of a carrot (Daucus carota L.) heat shock protein gene encoding HSP17.7 (DcHSP17.7) to confer enhanced heat tolerance to potato (Solanum tuberosum L.), a cool‐season crop. The DcHSP17.7 gene was fused to a 6XHistidine (His) tag to distinguish the engineered protein from endogenous potato proteins and was introduced into the potato cultivar ‘Désirée’ under the control of the cauliflower mosaic virus (CaMV) 35S promoter. Western analysis showed that engineered DcHSP17.7 was constitutively, but not abundantly, expressed in transgenic potato lines before heat stress. Leaves from multiple regenerated potato lines that contain the transgene exhibited significantly improved cellular membrane stability at high temperatures, compared with wild‐type and vector control plants. Transgenic potato lines also exhibited enhanced tuberization in vitro: under a condition of constant heat stress, at 29 °C, nodal sections of the transgenic lines produced larger and heavier microtubers at higher rates, compared to the wild type and vector controls. The dry weight and percentages of microtubers that were longer than 5 mm were up to three times higher in the transgenic lines. Our results suggest that constitutive expression of carrot HSP17.7 can enhance thermotolerance in transgenic potato plants. To our knowledge, this is the first study that shows that the thermotolerance of potato can be enhanced through gene transfer.
