Abstract：To screen shade-tolerant cultivars in zoysiagrass （Zoysia spp.），the‘Z. matella’ and four indepen dently selected hybrid cultivars were used as experimental materials.The shade tolerance was evaluated by comparing morphological index，dry weight，and turf quality under four artificial shading treatments （0% ， 35% ， 60% ， 80% ）. And the cultivation test was also conducted under a natural shading environment. The results showed that short-term treatment with 35% shading intensity had minimal negative effects on zoysiar grass growth. However，as shading duration and intensity increased，the relative canopy coverage and clipping dry weight of five zoysiagrasses exhibited declining trends，while turf height showed an opposite trend.After eight weeks of shading treatment，reductions were observed inthe canopy dry weight，rootdry weight，and rhizome dry weight to varying degrees，accompanied by a gradual decline in the turf quality. By principal component analysis and membership function methods，a comprehensive evaluation ranked the top three shade-toler ant cultivars as‘Suzhi No. 4′ ‘Suzhi No.3’and‘Suzhi No. 1⋅ .Under broad-leaved trees with the lowest shading intensity，the growth performanceof these zoysiagrasses aligned with the results from artificial shading treatments.This study provides a valuable reference for selection and application of shade-tolerant zoysiagrass.
