| Abstract/Contents: | "Stored nonstructural carbohydrates are a primary source of reserve energy in vegetative organs of warm-season grasses. Research is needed concerning the influence of potassium on carbohydrate levels in turfgrasses. Four K rates ranging from 24 to 390 kg ha⁻¹ per growing month were applied twice monthly from 1992 to 1994 to 'Tifdwarf' and 'Tifway' bermuda grasses [Cynodon dactylon(L.) Pers. xC. transvaalensis Burtt Davy] field grown on Uchee loamy sand (loamy, siliceous, thermic Arenic Hapludult) and sand peat (9:1 by volume) medium. Root + rhizome and shoot + stolon samples were evaluated monthly for total non-structural carbohydrate (TNC) concentrations by means of near infrared reflectance spectroscopy. TNC concentrations varied among cultivars, plant parts, and time of year. Tifdwarf produced 30% greater root + rhizome TNC concentration and 55% greater shoot + stolon concentration than Tifway. Higher K rates either did not influence or reduced root + rhizome TNC concentrations compared to low K rates. Correlation analysis indicated that root + rhizome yields and TNC concentrations were negatively influenced by temperature. Carbohydrate and root + rhizome yield responses suggest there is no benefit to applying K at rates beyond those that provide sufficient K levels for normal growth." |
