| Abstract/Contents: | "Declining availability of water for landscape irrigation has increased the need for drought-resistant turfgrasses. Though drought-resistance machanisms are known to include deep rooting in some plants, little is known concerning zoysiagrass rooting characteristics. This study was conducted to determine if differences in rooting parameters exist among zoysiagrasses, and if they are associated with drought resistance. Twenty-five zoysiagrasses cultivars and species [Zoysia japonica Steud., Z. matrella (L.) Merr., and Z. japonica Steud. x Z. tenuifolia Willd. ex Trin.] were studied in polyethlene tubes in a glasshouse. Differences were observed for average maximum root depth (AMRD), total root weight, and root numbers and weights at increasing 100mm depth increments. Grasses with superior AMRD, total root weight, and root numbers at deeper profile depths (300-500 mm) included QT2047, El Toro, DALZ8512, TC5018, Meyer, DALZ8514, and DALZ8516. In a previously reported field experiment, 11 of the 25 zoysiagrasses were rated for percent of plot area covered by green turfgrass (an indicator of drought resistance) under three levels of irrigation (0, 35, and 100% of turfgrass evapotranspiration [ET]). Average maximum root depth, total root weight, and root numbers at 200-, 300-, and 400-mm depths in polyethylene root tubes were positively correlated with percent green plot cover in the field under deficit irrigation (0 and 35% ET), indicating that rooting depth, weight, and branching at lower depths are important drought-resistance mechnisms in zoysiagrasses." |
