“…Both for the temperature measurements at the height of 2 m and 0.05 m above the ground level, regardless of the analyzed temperature threshold, a clear and statistically significant trend indicating an earlier occurrence of the last spring frost is most often observed. Such a shift is also reported by other researchers, e.g., [17,31]. However, this does not reduce the risk of losses in agriculture and horticulture-related to the occurrence of late and strong frosts.…”

Trends in the appearance of the last spring frost for three thresholds of minimum daily air temperature at the height of 2 m and near the ground were examined for six meteorological stations located in two agricultural regions in Poland. For most time series, the last spring frost, calculated as a consecutive day of the year, showed a statistically significant trend indicating its earlier appearance from 1.6 to about 3.5 days per decade. The date of the last spring frost was also calculated in relation to the ongoing growing season. In this case, few statistically significant changes in the dates of the last frosts were found. The probability of the last spring frost on a specific day of the calendar year and the day of the growing season was also examined for two periods: 1961–1990 and 1991–2020. For low probability levels corresponding to the early dates of the last spring frost, the last frost usually occurred much earlier (6–14 days) in 1991–2020. With the probability levels of 80–90% describing the late occurrence of the last frost with a frequency of once every 5–10 years, at some stations, the last spring frosts occurred at a similar time for both periods.

“…Simulations have shown that climate change may cause an advance of the date of last spring frost in some selected regions such as the Czech Republic, yet the benefits of a reduced frost risk derive primarily from the delay in the date of first frost in autumn [27]. Although climate change extends the season and reduces the incidence of frost events, they cannot be completely excluded in the future [1].…”

Securing Horticulture in a Changing Climate—A Mini Review

(1) Background: Climate change is on the rise due to continuous greenhouse gas emissions from anthropogenic activities ever since the industrial revolution. Changing weather conditions are likely to have consequences for horticulture. (2) Objective and Methods: A short literature review was conducted, gathering findings on climate change and the impacts on the yield and product quality of special crops. (3) Results: Global warming will result in elevated temperatures and CO2 concentrations in all seasons. Extreme weather events such as heat waves are also on the increase. In vegetables, physiological processes such as vernalization and winter chilling strongly rely on temperature. Therefore, heat stress may cause irregularities in yield production and planning the harvest. For fruit crops, frost poses a risk that is enhanced through climate change, as does a lack of chilling, as cold temperatures in the winter are required for flowering in the spring. Abiotic disorders in horticulture are also related to changing temperatures and humidity. The nutritional quality of special crops may be threatened by increasing rates of plant development and premature ripening at high temperatures. Quality traits such as sugars, acids, or antioxidant capacity may also shift as well. (4) Conclusions: Adapting to these new climate conditions means developing new climate-resilient varieties to maintain high production levels with superior quality. In this mini review, cultivation measures to mitigate adverse climate impacts are also discussed. Current developments and recent findings are presented, pointing out further steps toward adaptation and sustainable production.

“…1) of cultivation of large assortment of brassica vegetables (kohlrabi, Savoy cabbage, white-headed cabbage and cauliflower), root vegetables (celeriac, carrot and root parsley), bulb vegetables (onion and garlic) and legumes (green pea), while in the warmest parts of the Elbe lowland, growing thermophilic (fruiting) vegetables such as tomatoes and cucumbers. The potential impacts of climate change on the types of vegetables grown in the ERL (observed and projected of the frequency of frost occurrences, and changes in the timing of the growing season) has been described by Potop et al (2014aPotop et al ( , 2014b and Potopová et al (2015c). The ERL was chosen as study area because of particularly affect by a strong inter-annual variation in rainfall patterns and increases of temperature trends, and it also becoming a major producer of a large assortment of thermophilic vegetables.…”

“…In the CR, field vegetables are predominantly grown in areas around the lowland basins of such rivers as the Elbe, Vltava, Ohře, Morava, Dyje and Svratka which are agriculturally the most productive, but have a lowland climatic characteristics "low rainfall and higher potential evapotranspiration" and often affected by drought (Potop et al, 2014a(Potop et al, , 2014b. Vegetable production (depending of the grown-vegetable region) is being affected by high temperatures (South Moravia), occurrences of drought (Elbe lowland and South Moravia), late and early frosts (in all regions), waterlogging (in the wetness growing seasons e.g.…”

ABSTRACT. The study is focused on drought stress that is detrimental to yield formation of field-grown vegetables in the lowland regions of the Czech Republic. Extensive vegetable yield losses are attributed to drought, often in combination with heat or other stresses. The objective of this research was to investigate, under field conditions, the effect of drought stress quantified by the Standardized Precipitation Evapotranspiration
