摘要
以自然条件下生长的3种常见的冷季型草坪草品种早熟禾属优异(Poa pratensis L.cv.Merit)、抢手股(Poa pratensis L.cv.Blue chip)和紫羊茅属的紫羊茅(Festuca rubra L.cv.Cindy)和暖季型草坪草地毯草(Axorupus cornpressus(Sw.)Beauv.)和假俭草(Eremochloa ophiuroides)为材料,跟踪调查和测定了几种草坪草的脯氨酸含量变化规律,为进一步揭示脯氨酸在草坪草抗旱、抗寒和耐热中的作用奠定基础。
In this paper report,three cold-season-type lawn grass of Merit（Poa pratensis L.cv.Merit）,Blue Chip（Poa pratensis L.cv.Blue chip） and Cindy（Festuca rubra L cv.Cindy） grew naturally and two warm-season-type lawn grass of Carpet Grass（Axorupus cornpressus（Sw.）Beauv）,centipedegrass（Eremochloa ophiuroides）were taking as materials.Their proline content were determined at regular intervals.The results showed that the content of the soluble sugar and the free proline,which was a basis for further exploring the roles of drought and cold resistance and heat tolerance.
