“…Similarly, elevated temperatures about 30 °C have no effect on photosynthesis, or that severely inhibited photosynthesis for some heat susceptible or heat tolerant potato cultivars have also been published [32,33]. Different from Hancock et al [8] study that the content of photosynthetic pigments, chlorophyll a and chlorophyll b, significantly decreased up to 20% after moderately elevated temperatures with 30 °C at day and 20 °C at night up to 5 weeks, our results of potato exposure to heat up to 3 days in agreement with previous studies [4] that leaf chlorophyll a and chlorophyll b increased slightly at the higher temperature. Gene enrichment analysis revealed enhanced expression of transcripts associated with aspects of PSII polypeptide subunits and ferredoxin by short and continued heat treatment.…”

“…HS has an impact on development of different crop species [3]. Heat stress disrupts cellular homeostasis and leads to severe changes in structure and metabolic function as well as physiological process of plant [4]. Notably, heat stress is often accompanied by drought stress or other stresses that can cause extensive agricultural losses [5].…”

Background: Potato is the fourth world's most important crops. Global warming has heavily constrained potato production. Although some work has been undertaken regarding the response of potato to moderately increased temperature (25-30°C), few studies have examined the extreme high temperature above 35°C and sustaining high temperature impact on physiological, biochemical and molecular responses of potato. Methods: Potato plants were subjected to high temperature (35°C/33 °C day/night) treatments for 6 h (short) and 3 days (long), physiological and biochemical response of electrolyte leakage and photosynthetic performance were measured, transcriptome and metabolome profiles of leaves were examined. Expression profiles of 20 DEGs were verified by RT–qPCR, heat induced conserved genes were transient expressed in Nicotiana benthamiana.Results: Growth at short heat stress induced stomata open and lower membrane stability. Prolonged heat stress decreased the photosynthetic parameters and increased photosynthetic pigments. Integration of transcriptomics and metabolomics methods demonstrated that 448 heat upregulated and 918 heat downregulated genes as well as 325 and 219 compounds in the positive and negative ionization modes, respectively, that were up- or down-regulated in leaves detected in responsive to short and prolonged heat stress. Global transcripts changes were mainly induced by short heat stress, where metabolites changes were mainly activated by prolonged heat stress. General responses to heat stress in gene expression and metabolite accumulation enriched in amino acid metabolism and secondary metabolism pathway. Metabolite and transcript abundances for the up-regulation of flavone and flavonol biosynthesis under the prolonged heat stress were closely correlated. Both conserved and heat- and potato-specific stress responsive genes were identified by comparing heat and drought stress in potato as well as heat stress in potato and Arabidopsis shoots, transient expression of four heat induced genes in Nicotiana benthamiana exhibited heat tolerance to higher temperature.Conclusions: A new potato leaf transcriptomes and metabolomes revealed a widely adaptive response to high temperature by mainly generation and accumulation of heat shock proteins.

“…Potato plants are very sensitive to heat stress. In general, heat stress increases plant height, reduces leaf size, increases leaf chlorophyll content, and severely reduces tuber mass [43]. Kelpak SL contains auxins and cytokinins in a ratio of 350/1.…”

This paper analyses the effects of foliar application of the seaweed extracts Bio-algeen S90 (Ascophyllum nodosum) and Kelpak SL (Ecklonia maxima), as well as the humic and fulvic acids ini HumiPlant (leonardite extract), on the assimilation area and chlorophyll content of very early potato cultivars (‘Denar’, ‘Lord’, Miłek’). The field experiment was carried out in central-eastern Poland over three growing seasons, using Luvisol. The biostimulants were applied according to the manufacturers’ recommendations. The use of biostimulants resulted in enlargement of the assimilation area, but had no effect on the specific leaf area (SLA) or chlorophyll content (Soil Plant Analysis Development (SPAD) value). The assimilation area was larger, on average, by 0.0505 m2 and leaf area index (LAI) was higher by 0.30 compared with the plants from the control group without a biostimulant. The SLA and SPAD depend on the cultivar and weather conditions, or nitrogen and magnesium content in soil, to a greater extent. The biostimulants enhanced abiotic stress tolerance and increased marketable tuber yield (diameter above 30 mm) 75 days after planting (the end of June), on average by 2.15 t·ha−1. Bio-algeen S90 and Keplak SL produced better results in a warm and very wet growing season, whereas HumiPlant produced better results in a year with lower air temperature and with drought periods during potato growth. No correlations were found between the tuber yield and assimilation area or between the tuber yield and SPAD value, although a significant negative correlation was found between the tuber yield and SLA.

“…When the time of hightemperature treatment was shifted in the second half of July, beginning of maturation stage, the heat stress effects on the total tuber yield were minor but caused 13% decline in marketable yield due to tuber pre-harvest sprouting in the soil [15]. In Ontario, Canada, the potato yield decreased by 17.2% in 2016 compared with the production in 2015 as a result of extreme heat stress in summer [16]. Later investigation revealed that the primary planted and most popular cultivar Russet Burbank is exceptionally heat-vulnerable [16].…”

Potato, Solanum tuberosum L., is the most important non-grain food crop in the world, and a major vegetable crop in Serbia. It is generally considered a cool-season crop and highly susceptible to high temperatures. Elevated temperatures in the environment affect potato plants' growth and development by slowing the sprout emergence, reducing the number of stolons, impeding tuber initiation, reducing tuber bulking and interfering the onset of tuber dormancy. Tuberization is optimal at average daily temperatures in the 15-20 °C range and above this range declines, although moderately elevated temperatures of 20-25 °C may enhance potato foliage growth and the net photosynthesis. Besides reducing the number and mass of tubers, high-temperature stress affects the total and marketable yield of potato by causing tuber disorders and altering tuber processing and nutritive quality. The problem of potato heat-susceptibility is gaining more interest in the last decades due to occurring global climate change. The breeders' efforts have been intensified for selection of new, tolerant potato genotypes, as well as genomics' , proteomics' , and metabolomics' investigations of potato heat response.
