Austral summer frosts in the Andean highlands are ubiquitous throughout the crop cycle, causing yield losses. In spite of the existing warming trend, climate change models forecast high variability, including freezing temperatures. As the potato center of origin, the region has a rich biodiversity which includes a set of frost resistant genotypes. Four contrasting potato genotypes--representing...

Winter survial during an annual cycle of temperateand boreal-zone woody perennials is a multicomponent response. Two of these components are: (1) the timing, rate, and extent of cold acclimation (CA; Box 1), and (2) plants’ ability to sufficiently maintain its freezing tolerance (FT) until the danger of killing frosts is passed which is determined by, among other factors, plants’ ability to res...

The ongoing climate warming affects, among others, and the variability of thermal conditions in spring autumn are resulting earlier dates beginning end growing season. present paper provides detailed characteristics phenomenon ground frosts, addressing question whether risk frost-related damage extending season is still present. assessment temporal spatial distribution frosts (5 cm above level-...

The main stress factors for sweet cherries in the Krasnodar region are: late return frosts and early exposure to frost after a warm autumn. Against background of frosts, death generative organs cherry was 95%, realization productive potential − 3.3%; spring freezing fruit buds 30%, 47.8%. impact autumn, 90%, 5.6%. Under favorable weather conditions, i.e. absence any type stress, yield varieties...

A great number of organismiis can wvithstan(d temperatures below the freezing point of water. Many plants are even resistant against severe frosts especially during the winter months. In the late spring, during summer and in the early fall, however, they may be killed by moderate frosts. In order to gain resistance they must undergo a hardening process; in spring this resistance is lost by deha...

Climate change effects on snow cover and thermic regime in alpine tundra might lead to a longer growing season, but could also increase risks to plants from spring frost events. Alpine snowbeds, i.e. alpine tundra from late snowmelt sites, might be particularly susceptible to such climatic changes. Snowbed communities were grown in large monoliths for two consecutive years, under different mani...
