As a major class of pigments in plant tissues, anthocyanins are considered stress indicators because their biosynthesis can be induced by many environmental factors, in which low temperature (LT) is a nonignorable inducer ( Lo Piero, 2015 ; Zhang

. In apple, pear, and azalea, a low temperature exotherm (LTE) of dormant woody stem sections, detected by DTA, correlated with injury to both xylem and pith that occurred during cooling ( Graham and Mullin, 1976 ; Montano et al., 1987 ; Quamme et al

Rhizomes of zoysiagrass (Zoysia spp.) were subjected to controlled freezing tests in Jan. and Mar. 1993 and 1994 to determine their low-temperature tolerance. In 1994, `Belair', `Korean `Common', `Meyer', and `TGS-W10' rhizomes survived temperatures as low as -18 °C, while rhizomes of `Sunburst' survived -14 °C. `Cavalier', `Crowne', `Palisades', `Emerald', and `El Toro' were killed at -10 °C or warmer temperatures. Entries surviving exposure to -14 to -18 °C in 1994 controlled freezing tests received post-winter survival ratings in the field of 6.7 to 8.7 (9 = 100% green). Entries killed at higher freezing test temperatures were slower to recover after winter in the field, with ratings of 2.0 to 3.0. Shoot number produced after freezing was a better measurement for assessing low temperature tolerance than was shoot mass. Controlled freezing tests, using regrowth as a measure of hardiness, appear to be useful for identifying low temperature tolerance of zoysiagrasses in the early years of a field study.

Low temperature is detrimental to plant growth and development and thus affects the productivity of important warm-season food crops worldwide. Cucumber, for example, is susceptible to low temperatures throughout its growth cycle ( Jackman et al

Germination of melon seeds at low temperatures is cultivar-dependent. By screening hundreds of accessions (Nerson and Edelstein, 1982–1984, unpublished data), it was concluded that a temperature of 14 to 15 °C can be used to distinguish between
