Temperature stress during reproductive phase of life is among environmental constrains with
the most adverse effect on pumpkins, at least in the fields of South and East Europe. The growing
season (May-September) of 2017 was characterized by 56 days of high (>30 °C) and 21 days of extremely
high (>35 °C) maximum daily temperatures, differing from the temperate season of 2016
(33 and 0 days), and from the 1981-2010 averages of 32.4 and 3.3 days, respectively. This was an
opportunity to analyze the effects of the stress on pumpkin quality and agronomic traits. The investigation
was undertaken on field-grown Cucurbita maxima and Cucurbita moschata collections,
each comprising 41 genetically divergent accessions. All appropriate agro-technical procedures,
including irrigation, were applied in both seasons of the experiment (2016, 2017); therefore high
temperature was the only stress to which the plants were exposed. The most affected by the stress
was carotenoid content, which wa...s 64.1% (C. maxima) and 75.4% (C. moschata) lower comparing
to the values noted in the temperate season. Concerning other quality traits, protein content was
44.6% reduced in C. moschata, and slightly (6.1%) increased in C. maxima. Dry weight and total soluble
solids contents were moderately increased in both species; and sugar content in C. moschata
only. Refractive index and pH were unaffected by the stress. Concerning agronomic traits, temperature
stress decreased the fruit weight (23.1, 17.3%) and therefore the yield of both C. maxima
(27.0%) and C. moschata (16.1%), exhibiting no significant effect on number of fruits per plant.
