“…(L.) Rich.] Bermudagrass reaches limitations of adaptation where low-temperature stress causes frequent plant mortality (Gatschet et al, 1994;Taliaferro, 1995;Anderson et al, 2007;Rutledge et al, 2009). Although the grass is considered to have excellent heat and drought tolerance, its ability to survive freezing temperatures is limited (Beard, 1973), and bermudagrasses periodically sustain winter injury in the transition zone Richardson et al, 2014).…”

Bermudagrass [Cynodon spp. (L.) Rich.] is a high‐quality, durable turfgrass with excellent heat and drought tolerance. However, its lack of freezing tolerance limits its use in the transition zone. The development of cultivars with enhanced freezing tolerance would constitute a significant improvement in the management of bermudagrass in this region and could extend its area of adaptation further north. There has been substantial work on screening of common‐type bermudagrass [Cynodon dactylon (L.) Pers.] germplasm for freezing tolerance, but not for the African (Cynodon transvaalensis Burtt‐Davy) germplasm. The purpose of this research was to conduct multiyear field testing and laboratory‐based freezing test evaluations of winter hardiness and freezing tolerance, respectively, of an African and common bermudagrass germplasm collection. A high level of cold hardiness was observed among the germplasm in this study. In field evaluations, plant introductions (PIs) PI 290905, PI 647879, PI 255447, PI 289923, and PI 615161 were the top performers, having consistently greater spring green‐up and reduced winterkill compared with ‘Patriot’, ‘Tifsport’, ‘Quickstand’, and ‘Tifway’, though not always significantly. A comparison between field‐based ratings and calculated lethal temperatures for 50% death (LT50) from laboratory‐based freezing tests showed significant correlations of −0.26 and −0.24 for spring green‐up and winterkill, respectively, suggesting that these controlled freeze experiments could be used to prescreen materials prior to field testing. Overall, results indicate that some of the PIs evaluated in this study can be used as additional sources of cold hardiness in bermudagrass breeding.

Bermudagrasses (Cynodon spp.) are commonly used in golf courses, athletic fields, and home lawns in the transitional climatic region of the United States. Winterkill, however, is a major concern for bermudagrasses grown in this region. Controlled environment testing is a reliable method to evaluate freeze tolerance contributing to the selection of freeze tolerant genotypes. Therefore, this study was designed to test the freeze tolerance of two elite experimental genotypes, OKC1873 and OKC1406, along with two industry standards ('Tifway' and 'Tahoma 31'), by exposing them to various freeze temperatures (−4 to −14°C) in a controlled environment. The freezing test was replicated in time, and the mean lethal temperature to kill 50% of the population (LT 50 ) for each genotype was determined. Tifway (freeze-sensitive standard) had an LT 50 value of −7.0°C. The genotype OKC1873 (−7.2°C), was in the same statistical group as Tifway. Tahoma 31 was the best-performing genotype with the lowest LT 50 value of −9.1°C. The genotype OKC1406 (−8.8°C) was in the same statistical group as Tahoma 31. Top-performing experimental genotypes will move on for further screening in replicated field trials for future consideration for commercial release based on qualities such as improved freeze tolerance, desirable turfgrass quality, and sufficient disease resistance.

Clippings return decreases mineral nitrogen requirements for bermudagrass (Cynodon spp.) lawns in Mediterranean Europe

The use of bermudagrass [Cynodon dactylon (L.) Pers.] and hybrid bermudagrass (C. dactylon x C. transvaalensis Burtt Davy) in lawns is rapidly increasing in Mediterranean Europe; however, the identification of optimal N fertilization practices is needed to shorten the long dormancy periods some cultivars undergo in these environments. A 2‐yr study was conducted at the agricultural experimental farm of Padova University from May 2016 until June 2018 to compare the effects of three N fertilization rates (160 kg N ha−1 without clippings returned, 80 kg N ha−1 with clippings returned, and 80 kg N ha−1 without clippings returned applied with a controlled‐release fertilizer) on two bermudagrass cultivars (‘La Paloma’, ‘Yukon’) and two hybrid bermudagrass cultivars (‘Patriot’, ‘Tifway’) by measuring summer and fall quality, spring green‐up, and root morphology. Bermudagrasses fertilized at 160 kg N ha−1 without clippings returned slightly increased turfgrass quality in the summer, but higher turf quality was recorded in plots fertilized at 80 kg N ha−1 with clippings returned after weekly mowing events in the fall. The same N rates had a positive effect on spring green‐up for ‘La Paloma’ and ‘Tifway’; however, no benefits of increased N rates were detected on root morphology. Results suggest that returning clippings can be a powerful tool for reducing mineral N applications and increase growing season length in northern Italy.
