Hybrid bluegrass survive prolonged heat and drought periods. It provides more of a natural look and needs very little water. Kentucky Bluegrass can recover from drought but needs more than 4 weeks of adequate water for a complete recovery. Introduction Drought is one of the major environmental factors that affect plant growth and survival worldwide. 2017 Jul;214:123-133. doi: 10.1016/j.jplph.2017.04.008. Many bluegrass lawns can survive weeks even months without any supplemental irrigation. SPF 30 produces a high percentage of living ground cover throughout the summer, recovers quickly from drought, and is resistant to brown patch. Its important to note that during a drought, Kentucky Bluegrass enters dormancy, where it turns brown and may appear dead. Hybrid bluegrasses possess a strong creeping growth habit due to rhizomes (underground stems). with perennial ryegrass. Low-water use cultivars had 13% more horizontal leaf orientation, 6% narrower leaf texture, 13% more lateral shoots per plant, 12% slower vertical leaf extension rate, 2% more leaves per shoot, and 7% shorter leaf blades and sheaths than the high-water use cultivar [21]. Chen Y, Chen Y, Shi Z, Jin Y, Sun H, Xie F, Zhang L. Int J Mol Sci. Turfgrass as . It is a low-water user and may send roots as deep as 6 feet in the right conditions. Bluegrass that enters dormancy may require 23 weeks to exit dormancy once water returns. Deeper root system in Kentucky bluegrass can avoid drought stress more consistently than total root mass [24]. color and year-round performance, Kentucky bluegrass is often mixed Some of the most drought resistant bluegrass cultivars include: America, Apollo, Baroness, Brilliant, Impact, Mallard, Midnight, Midnight II, Moonlight, Rugby II, Showcase, Total Eclipse, and Unique. and management tips, Turf Enjoying a low-water landscape starts with choosing the right drought-tolerant lawn grasses. Competitor Grasses. Maintaining active photosynthesis is important for plant adaptation to drought stress. It beats Bluegrass in this category, but you can get the benefits of both by mixing the two grass types. CK means. Perennial Ryegrass lawns often come back from drought patchy and irregular. This dormancy period allows the grass to ride out drought conditions for up to 6 weeks before it begins to die. Main causes of water deficiency may result from low rainfall, inadequate irrigation, as well as summer heat, which could greatly limit growth, and turf quality of Kentucky bluegrass. If allowed to enter dormancy in summer, Kentucky Bluegrass can become invaded with weeds. These researches on antioxidant metabolic responses revealed key information for controlling drought tolerance in turfgrass species and would facilitate the development of drought-tolerant germplasm through biotechnology. Texas Blue produces a dense, dark green ground cover throughout the summer, recovers quickly from drought and is resistant to brown . (Its range actually extends beyond the South and Southwest, and it can be found in plains states from North Dakota to Texas.) Join our mailing list to keep tabs on how to care for your lawn!

A wide range of diverse cultivars and accessions of Kentucky bluegrass have been characterized based on pedigree, common turf performance, and morphological characteristics and were grouped into different genotypes such as Common, Compact, Compact-America, Julia, Mid-Atlantic and Midnight types [3]. tolerate cold winters but has a relatively low tolerance for heat and is Some studies found that the activity of superoxide dismutase (SOD) increased while that of catalase (CAT) and peroxidase (POD) decreased in leaves of Kentucky bluegrass when only surface soil drying was simulated [39]. -, Xu L, Yu J, Han L, Huang B. Photosynthetic enzyme activities and gene expression associated with drought tolerance and post-drought recovery in Kentucky bluegrass. Although these germplasm possess prominent ornamental value, however, Kentucky bluegrass extremely limiting used by water scarcity in practice, especially in semiarid, arid regions as well as the areas with the increase demand on water for agricultural, residential and industrial use [4, 5, 6]. Here are the best drought-tolerant lawn grasses for different regions of the country. CSU A-Z Search In cool conditions, Kentucky Bluegrass thrives on 1 inch (2.5 cm) of water per week. Some studies on Kentucky bluegrass discovered that the interaction of endogenous hormones could contribute to increase drought resistance. Mixtures possessing a higher proportion of tall fescue or Kentucky bluegrass stayed green longer (Figure 3). Transcriptome analysis of Kentucky bluegrass subject to drought and ethephon treatment PLoS One. Droughts can be tough, but reviving your lawn post drought doesnt have to be. The relationship of ABA accumulation and drought resistance in different genotypes of Kentucky bluegrass varied. Dr. James Klett discusses the history of PlantTalk Colorado. Bluegrass cultivars differ little in actual water use rate. The authors have declared that no competing interests exist. This is because Ryegrass is a bunch-forming grass. The objective of this study was to determine major photosynthetic factors associated with genetic variability governing drought tolerance and post-drought recuperative ability of a perennial grass species, Kentucky bluegrass (Poa pratensis), by examining differential photosynthetic responses and underlying . Turf industry has released many improved Kentucky bluegrass cultivars in the world since last century. After 6days of rewatering, Midnight displayed significantly higher activity levels of CAT, POD, and APX compared with Brilliant. In addition, the increases in the activities of ascorbate peroxidase (APX), monodehydroascorbate reductase (MHAR), dehydroascor bate reductase (DHAR) in leaves and that of CAT, glutathione reductase (GR), and MHAR in roots, but reduction in the activities of SOD and DHAR in roots [42]. Tall Fescue recovers very well from drought, returning to a lush lawn in 34 weeks. doi: 10.1007/s10535-016-0584-8 What is the Most Drought-Tolerant Kentucky Bluegrass Cultivar? Licensee IntechOpen. To receive A-LIST approval, a cultivar must have acceptable turfgrass quality and be in the top statistical group for drought tolerance for two years at two or more locations. For the leaves, the expressions of iron SOD (FeSOD), cytosolic copper/zinc SOD (Cu/ZnSOD), chloroplastic Cu/ZnSOD, and DHAR were down-regulated by drought stress but recovered to control level after rewatering, while the expressions of GR and MDHAR were up-regulated and remained that levels after recovery. This will help you make the right choice for your lawn. One of its limitations is that it doesnt form a nice, dense carpet like most of the other warm-season grasses. The functions and the signaling pathways of ABA in plants responses to drought stresses have been extensively studied, and it is now well accepted that ABA plays important roles in plant including turfgrass adaptation to environmental stresses [5, 48, 49]. Webmaster | This is the natural Bluegrass reaction to insufficient summer water. As a species, Kentucky bluegrass is remarkably heat and drought tolerant as demonstrated by the survivability of bluegrass lawns during the recent drought years.

Water conservation in turf management becomes extremely important. Ethephon improved drought tolerance in maize seedlings by modulating cuticular wax biosynthesis and membrane stability. Fescue will remain green in summer with 11.25 inches of waterhalf of what Kentucky Bluegrass requires.

It often has greater heat tolerance and can tolerate more shade than Kentucky bluegrass. government site. CK means well-watered control plants without ethephon application. Tall Fescue is the best choice among cool-season grasses when it comes to water conservation, drought hardiness, and drought recovery. Therefore, drought escape is only considered a viable alternative for Kentucky bluegrass in those areas where irrigation is not available and survival of the turfgrass following drought is the primary objective [17]. How Long Can Kentucky Bluegrass Go Without Water? Epub 2014 Jun 29. Previous research has reported that irrigating turfgrasses below levels of maximum crop evapotranspiration (ET c) may not result in unacceptable turfgrass quality. Hybrid bluegrasses germinate from seed slightly faster than Kentucky bluegrass, but the differences in overall establishment rate have not been significant. Drought-tolerance midnight and drought-sensitive Brilliant as drought research model cultivars of Kentucky bluegrass have been detected 88 drought-responsive proteins by gel electrophoresis and mass spectrometry analyses. In response to drought stress, various adaptation strategies of Kentucky bluegrass were taken based on morphology, physiology and genetics. Kentucky Bluegrass recovers from drought better than Ryegrass. Theres even a tall fescue bred to withstand the tough growing conditions in the South:Scotts Turf Builder Grass Seed Southern Gold Mix for Tall Fescue Lawns, which thrives in harsh summer conditions, even in high-traffic areas. SPF-30 has also demonstrated persistence in partial shade areas in warm-season regions where low light condition are not suitable for Bermudagrass. These studies suggest importance of molecular functions and related genes for protection and improvement in Kentucky bluegrass tolerance to drought, however, molecular mechanisms underlying drought tolerance in Kentucky bluegrass are largely unknown. Two Kentucky bluegrass cultivars contrasting in drought tolerance were evaluated the photosynthetic responses and underlying enzyme activities during drought stress and re-watering [31].

In addition, the stomatal conductance, photosynthetic rate, leaf water potential and turf quality in drought resistant cultivars performed less severe decline during drought than drought sensitive cultivars, indicating that stomatal conductance was negatively related to ABA accumulation and the ABA concentration during drought could regulate by stomatal behavior of Kentucky bluegrass [31]. Based on a random spaced plant of 61 Kentucky bluegrass cultivars under untrimmed conditions, the morphological properties and comparative water use rate were strongly correlations by use discriminant analysis [21]. Disclaimer | With regular mowing, tall fescue can provides a "carpet" effect of a traditional lawn. The objective of the following research was to evaluate the field drought tolerance of Kentucky bluegrass (Poa pratensis L.) cultivars and compare their drought tolerance to rooting capacity. Kentucky bluegrass (Poa pratensis L.) is one of the most popular cool-season turfgrass species. Newcomers to Colorado will find specific information to successfully garden in Colorado's diverse climate and geography. Ordering Info Results showed that ethephon could improve the drought tolerance of Kentucky bluegrass by elevating relative water content and decreasing malondialdehyde content under drought. If youre in an area with terrible soil, though, bahiagrass is a good option. Although Kentucky bluegrass can escape by going into dormancy under severe drought conditions especially during summer periods [16]. It gets its drought tolerance from the small amount of water it requires, its deep roots, and its ability to go dormant and then recover from drought. When summer heatwaves hit, the Kentucky Bluegrass root zone dries out quickly. It is not a very drought-tolerant grass. . It often comes back patchy, with dead areas. Welcome Yard Grass Types Bermuda Grass Is Kentucky Bluegrass Drought Tolerant? Kentucky bluegrass (Poa pratensis L.) is an excellent cool-season turfgrass and is extensively used in public parks, golf courses and residential lawns in temperate and cold temperate zones and cool plateau areas. The majority of these dead lawns had been damaged by spider mites, not properly managed prior to the drought (poor mowing, fertilization, irrigation, and other cultural practices), or were planted in poorly prepared soil. Disclaimer. The mechanism for how ethephon regulates drought response and improves drought tolerance of, MeSH Called the Cadillac of lawn grasses, the ubiquitous Kentucky bluegrass (KBG) is synonymous with gorgeous and lush yards and turfs all across the northern United States. Although some Bluegrass plants can survive beyond 8 weeks without water, this wont be true for the entire lawn. Epub 2017 Mar 20. Thanks to its deep roots, Tall Fescue can survive short droughts without turning brown, and it recovers quickly from drought conditions. Limited research (along with many anecdotal field observations) suggests that the Texas bluegrass x Kentucky bluegrass hybrids (Reveille, Longhorn, Thermal Blue, Solar Green, Dura Blue, Bandera) have better than average drought resistance and excellent heat tolerance. DEGs were quantified at false discovery rate threshold (FDR) of 0.001 and log2 (fold change) larger than 2. It is also true that while a large number of bluegrass lawns died or were found dead in the spring after extended dry periods. Kentucky bluegrass (Poa pratensis L.) is an excellent cool-season turfgrass and is extensively used in urban green space, parks and sports fields worldwide, but it is sensitive to drought. Kentucky Bluegrass can survive a drought of up to 8 weeks. The exogenous ABA application on Kentucky bluegrass demonstrated that ABA sprayed on leaves can help maintain higher turf quality and delayed the quality decline during drought stress. The increased SOD activity in Kentucky bluegrass leaf cannot inhibit formation and accumulation of free radicals, but only delay accumulation of free radicals to a certain extent for alleviate active oxygen damage to cells [40, 41].
