Stolon Growth and Tillering of Experimental Zoysiagrasses in Shade Academic Article uri icon

abstract

  • Zoysiagrass (Zoysia spp.) grown under shade on golf courses and in home lawns is slow to recover from damage and declines in quality over time. We evaluated stolon growth and tillering of Meyer and Chinese Common (both Z. japonica Steud.); Zorro, Diamond, and Cavalier [all Z. matrella L. (Merr.)]; Emerald (Z. matrella Z. pacifica Goudsw.); and six experimental progeny from Emerald Z. japonica and reciprocal crosses of Z. japonica Z. matrella under silver maple (Acer saccharinum L.) shade and in full sun in 2008 and 2009 in Manhattan, KS. A single 6-cm diameter plug was planted in the center of 1.2 m 1.2-m plots, and data were collected weekly on the number of stolons, stolon elongation, and number of stolon branches. Tiller number was collected at the start and end of each study period, and biomass (excluding roots) was determined at the end of each season. Zoysiagrasses under an average of 76% tree shade exhibited reductions of 38% to 95% in stolon number; 9% to 70% in stolon length; 10% to 93% in stolon branching; and 56% to 98% in biomass. Seven of the 10 grasses exhibited a decline in tiller number in each experiment; none of the grasses differed from Meyer in percentage change in tiller number under shade. Emerald, Cavalier, Zorro, and several progeny from crosses between Emerald Z. japonica or reciprocal crosses of Z. matrella Z. japonica produced more, longer, or more highly branched stolons than Meyer, suggesting they may have improved recovery potential in shade.
