Salt-tolerance appraisal of turfgrasses in Tianjin city

针对天津市引进的高羊茅Festucaarundinacea、黑麦草Loliumperenne、碱茅Puccinellinatenuiflora、百克星Barkoel、大穗结缕草Zoysiamacrostachya草种进行了耐盐性鉴定 ,结果表明 :高羊茅、黑麦草各品种之间耐盐能力没有明显差异 ,且发芽期的耐盐能力优于苗期 ,而碱茅发芽期的耐盐能力不如苗期。几种草的综合耐盐性 :碱茅 >黑麦草 >高羊茅 >

Salt-tolerance appraisal was carried out for Fest uc a arundinacea, Lolium perenne,Puccinellina tenuiflora, Barkoel and Zoysia ma crostachya varieties introduced to Tianjin city The results did not show an obvious difference in salt tolerance between tall fescue and perennial ryegrass Their salt tolerance was better during germination than at the seedling stage On the contrary, the salt tolerance of Puccinellina tenuiflora was better during the seedling stage than the germination stage Salt-tolerance appraisal of several turfgrasses gave the following order:Puccinellina tenuiflora >Lol ium perenne> Festuca arundinacea> Barkoel
