Abstract
In view of the popularity of economical gardens , ornamental grasses are attracting more and more attention.In this study, the growth and the ornamental value of 16 species of introduced perennial orna -mental grass were evaluated in summer and autumn in Linyi by gray -correlation analysis.The characters such as the growth, ornamental value, inflorescence aesthetics and leaf color were selected as the evaluation indexes to select varieties with good adaptability and provid theoretical supports for application of ornamental grass in Linyi.The results showed that Pennisetum alopecuroides, P.orientale 'White', P.orientale 'Small' and Fe-stuca glauca showed better performance with the correlation degrees more than 0.75, and could keep steady ornamental values both in summer and autumn .Miscanthus sinensis 'Zebrinus', M.sinensis 'Gracillimus' and Cortaderia selloana had high ornamental value in autumn since their flowering .The ornamental values of Imperata cylindrical, Arundo dona and Eragrostis pilosa were low and the correlation degree was below 0.60, which was not suitable for greening in Linyi .关键词
