Fluxapvroxad + pyraclostrobin may hasten establishment of refrigerated ultra-dwarf hybrid bermudagrass plugs

摘要

Prolonged postharvest storage of vegetatively propagated tur-fgrass (either sod, sprigs, or plugs) can contribute to reduced transplant success. Inside a stored sod mass, such as a pallet of stacked sod or a mass of sprigs or plugs, there is limited exposure to light and atmospheric gasses. In these conditions, tur-fgrasses increase respiration by metabolizing stored carbohydrates (Darrah & Powell, 1977). Additionally, increased activity of anaerobic microorganisms may lead to internal heating (Pahlow et al., 2003). Thus, refrigeration is an increasingly common technique for prolonging the lifespan of vegetatively propagated sod and sprigs (Bowman &, Burger, 2007; Brede, 2000) and has been linked to extended sod shelf-life (Minaev et al., 2020).
