Salinity and waterlogging are two major abiotic stressors commonly associated with irrigated soils. In this experiment, tall fescue cv. Stonewall, Kentucky bluegrass cv. Bewitched, blue grama ecotype Bad River, and buffalograss cv. Texoka were germinated under well‐drained (control), waterlogging (i.e., flooding), saline (5 g NaCl/liter), or a combination of waterlogging and saline conditions (saline‐waterlogging) in two greenhouses (Study I and II). Plants were evaluated on germination percentage, shoot and root fresh weight, and the longest root length. Waterlogging with tap water did not inhibit seed germination or seedling growth. Germination, shoot and root fresh weight, and the longest root length were significantly decreased under saline conditions, alone or combined with waterlogging. The highest reduction occurred under saline condition alone which ranged from 36% of the control in the longest root length in Study I to 1% of the control in root fresh weight in Study II. Soil salinity levels were similar between the control and waterlogging treatments, which was significantly lower than the salinity treatment and the combined effects. Tall fescue was the most tolerant to both salinity and waterlogging stresses. Kentucky bluegrass, blue grama, and buffalograss showed a similar level of tolerance to salinity, waterlogging, and the combined stress.

“…The turf species were held under a moderate salt stress level of EC w 6 dS m À1 for 7 weeks, reported to be critical level of salinity resistance especially for perennial ryegrass (Harivandi et al 1992). Clipping yield, one of indicators of turf vigor and used in determination of salinity tolerance (Van Genuchten and Hoffman 1984;Shannon 1997), varied among treatments with measurement date on both species.…”

Effects of 24‐epibrassinolide application on cool‐season turfgrass growth and quality under salt stress

et al. 2017

Brassinosteroids are steroidal phytohormones with a significant role in the amelioration of various stresses. The objective of this study was to determine the effect of foliar application of 24‐epibrassinolide (EBL) on growth and quality of perennial ryegrass (Lolium perenne L.) and tall fescue (Festuca arundinaceae Schreb.) grown under salt stress. The plants were grown under non saline or saline conditions (6 dS m−1), and were sprayed with 0.00 and 0.15 mg L−1 EBL. Salt stress significantly reduced the shoot growth and turfgrass quality. However, EBL alleviated detrimental effects of the salt stress by enhancing turfgrass quality (7–26%), and increasing shoot growth and clipping yield. The EBL application under salt stress alleviated loss in clipping yield by 35 and 12%; and reduced leaf firing, through weeks 2–6 post‐application, by 75–40 and 50–20% for perennial ryegrass and tall fescue, respectively. The EBL may find additional use in stress management of turfgrass areas.

“…Irrigation water with EC w = 9.3 and 12 dS/m corresponds to an EC w of 3.97 and 5.7 dS/m, respectively, in the soil water extract (Cornacchione and Suarez, 2015;Dias et al, 2016). Soils with electrical conductivity of 4 dS/m are considered saline (Ali Harivandi, Butler, & Wu, 1992;Richards, 1954). As it has been recently shown, irritation of Jerusalem artichoke with low salinity water followed by high salinity water (sequential strategy) relieved salt stress on tuber productivity when tested for salinities up to that for an irrigation water EC of 9.3 dS/m.…”

Currently, major biofuel crops are also food crops that demand fertile soils and good-quality water. Jerusalem artichoke (Helianthus tuberosus, Asteraceae) produces high tonnage of tubers that are rich in sugars, mainly in the form of inulin. In this study, plants of the cultivar "White Fuseau" grown under five salinity levels were evaluated for tuber yield. Results indicated that this cultivar is moderately salt-tolerant if the goal is tuber production. Hydraulic pressings of the tubers produced juice that contained 15% (wet weight) or 55% (dry weight) free sugars, with 70% of these in the form of inulin and the rest as fructose, sucrose, and glucose. Importantly, salinity did not affect the total free sugar or inulin content of the tubers. Tubers were composed of about 12% dry washed bagasse (wet weight) or 44% (dry matter basis) and bagasse retained such high quantities of free sugars after pressing that washing was required for complete sugar recovery. Chemical composition analysis of tuber bagasse suggested that it had low lignin content (11-13 wt%), and its structural sugar composition was similar to chicory root bagasse. Because of the high hemicellulose and pectin content of the bagasse, adding xylanase and pectinase to cellulase substantially improved sugar yields from enzymatic hydrolysis compared to at the same protein loading as cellulase alone. In addition to the high total sugar yield of tuber, these first findings on the sugar and lignin content and enzymatic hydrolysis of tuber bagasse can lead to low-cost production of ethanol for transportation fuels.
