Abstract

Abstract: Growth and ornamental value of 20 introduced perennial ornamental grass were evaluated in Beijing by gray-correlation analysis based on the characters of p lant growth, ornamental value, inflorescence aesthetics, leaf color and over wintering survival etc. The results showed that Anemathele lessoniana and Imperata cylindrica were not suitable for growing in Beijing because of their low overwintering survivals. Elytrigia repens, Festuca ovina, Stipa krylovii and Eragrostis curvula can be used for landscape in spring and their correlation degrees to perfect species were more than 0.80 in spring. Arundinella hirta, Elytrigia repens, Eragrostis curvula, M iscanthus sinensis‘Variegatus’ and Pennisetum alopecuroides have good ornamental values in summer aswell as higher correlation degrees. The p lant color of Miscanthus sinensis‘Variegatus’, Spodiopogon sibiricus, Arundinella hirta and Schizachyrium scoparium changed alongwith the season alternation, and their correlation degrees were higher than 0.80.

Key words: Ornamental plant, Gray-correlation analysis, Ornamental value, Evaluation
