摘要 本试验以中华结缕草(Zoysia sinica)、假俭草(Erem ochloa ophiuroides)、高羊茅(Festucaarundinacea)和多年生黑麦草(Lolium perenne)为材料,研究了30℃测试条件下它们的光强依赖的叶绿素荧光特性。发现随着光强升高,相对于高羊茅和黑麦草,中华结缕草和假俭草的开放的PSⅡ反应中心捕获激发能效率(F′v/F′m)、PSⅡ电子传递量子产率(ФPSⅡ)、光化学猝灭(qP)下降较慢,而表观电子传递速率(ETR)上升较快。尽管高羊茅和黑麦草有较高的非光化学猝灭(qN),但由于其较低的qP和ФPSⅡ,在高光强下仍然容易引起光抑制,造成ETR的降低。因此可以认为冷季型草坪草黑麦草和高羊茅的耐光抑制能力较弱,而暖季型草坪草中华结缕草和假俭草的较强。利用非损伤的叶绿素荧光技术可以用来快速鉴定不同基因型草坪草的耐光抑制能力。 hibition-tolerant To investigate the adaptive capacity to light irradiance, and to screen for the different photointurf grass species for different regions, we explored light-dependent chlorophyll fluorescence properties in four turfgrass species: Zoysia sinica, Eremochloa ophiuroides, Festuca arundinacea, Lolium perenne. The results showed that with increasing of light intensity under 30℃, there is a slower decrease in efficiency of energy conversion of open PS Ⅱ ( F'v/F'm), actual PSⅡ efficiency ( ФPS Ⅱ ) and photochemical quenching (qP), and a faster increase in electron transport rate (ETR) in Zoysia sinica and Eremochloa ophiuroides, as compared with Festuca arundinacea and Lolium perenne. Although Festuca arundinacea and and Lolium perenne appear to suffer photoinhibiton more easily than warm-season t Eremochloa ophiuroides do and that noninvasive different photoinhibition-tolerant genotypes. urfgrasses Zoysia sinica and chlorophyll fluorescence techniques may be used to identify for different photoinhibition-tolerant genotypes.
