“…The data observed from a freeze tolerance study of fertile turf‐type C. dactylon var. dactylon (Anderson and Taliaferro, 2002) showed that there was a significant correlation between freeze‐tolerance value and average annual temperatures at the geographic origins of the bermudagrasses.

The ability to survive harsh winters is one of the primary factors limiting bermudagrass (Cynodon spp.) distribution, especially those used for forage. Consequently, improved stress tolerance has been a goal of programmes for breeding bermudagrasses. While significant progress has been made in developing and evaluating freeze tolerance of turfgrasses, information on forage bermudagrasses is limited. Our objective was to evaluate freeze tolerance of recently released forage bermudagrasses compared with standard cultivars. Plants were established and acclimated in growth chambers and exposed to sub-freezing temperatures in a programmable freeze chamber. Plant responses to low-temperature exposures were quantified by regrowth mass. Freeze tolerance of Tifton 44 and Coastal was not significantly different from Midland, the reference cultivar. Coastcross, Tifton 85 and Tifton 68 were more susceptible to low-temperature injury than Midland, while Hardie, Goodwell, Midland 99 and Ozark were more freeze tolerant than Midland. Ozark, Midland 99, Goodwell and Hardie are less likely to sustain winterkill than Coastcross, Tifton 85 and Tifton 68 in areas that frequently experience low temperatures. Cultivars with one or more parents originating in Kenya had poor freeze tolerance, while germplasm from Yugoslavia and Afghanistan produced plants that were more freeze tolerant.

“…Low temperature (LT) is one of the most important abiotic stress factors affecting plant survival and growth, and it is also the main factor that determines the geographical distribution and growth season of plants [1]. Cold resistance is a complex feature and can be a major influence on plant survival [2].…”

Low temperature (LT) is an important abiotic factor affecting plant survival, growth and distribution. The response of Cryptomeria fortunei (Chinese cedar) to LT is not well known, limiting its application in production and ornamental value. In this study, we first screened ten clones (#3, #25, #32, #42, #54, #57, #68, #66, #74, #X1), originating from five different locations in China, for their degrees of cold resistance. We then selected the two showing the highest (#32) and lowest (#42) cold resistance to see the physiological and morphological response of different cold-resistant C. fortunei clones to LT. We found that the electrolyte leakage of all ten clones increased strongly between 0 and −8 °C, while below −8 or between 4 and 0 °C did not yield additional increases. Under cold stress, clones #32 and #42 showed different degrees of needle browning. From 25 to −20 °C, maximum and effective quantum yields of photosystem II (Fv/Fm and YII) and photochemical and non-photochemical quenching (qP and NPQ) decreased continuously in two clones with decreasing temperature, where #42 was more strongly affected compared with #32. The chlorophyll content first decreased significantly to the lowest from 25 to −12 °C, then increased significantly at −16/−20 °C compared with −12 °C. We observed changes in needle cellular ultrastructure at −8 °C, with chloroplasts of #32 swelling, while those of #42 were destroyed. Correlation analysis indicated that needle browning and chlorophyll fluorescence were closely related to temperature, and cellular ultrastructure changed notably around semi-lethal temperature (LT50), which can be used as physiological indicators for the identification of cold resistance. We found a clear difference in cold tolerance between clones of #32 and #42, with #32 being more tolerant, which can be exploited in breeding programs. We conclude that strongly cold-resistant clones have more stable physiological states and a wider adaptability to LT compared with weak ones.

Limited information is available on the cold acclimation of non-heading Chinese cabbage (NHCC) under low temperatures. In this study, the isobaric tags for relative and absolute quantification (iTRAQ) were used to illustrate the molecular machinery of cold acclimation. Compared to the control (Cont), altogether, 89 differentially expressed proteins (DEPs) were identified in wucai leaves responding to low temperatures (LT). Among these proteins, 35 proteins were up-regulated ((and 54 were down-regulated). These differentially expressed proteins were categorized as having roles in carbohydrate metabolism, photosynthesis and energy metabolism, oxidative defense, amino acid metabolism, metabolic progress, cold regulation, methylation progress, and signal transduction. The fructose, glucose, and sucrose were dramatically increased in response to cold acclimation. It was firstly reported that aspartate, serine, glutamate, proline, and threonine were significantly accumulated under low temperatures. Results of quantitative real-time PCR analysis of nine DEPs displayed that the transcriptional expression patterns of six genes were consistent with their protein expression abundance. Our results demonstrated that wucai acclimated to low temperatures through regulating the expression of several crucial proteins. Additionally, carbohydrate and amino acid conversion played indispensable and vital roles in improving cold assimilation in wucai.
