摘要:
以紫薇品种金幌和粉晶为材料,对其由低光照
[50~120 μmol/(m2·s)]转向高光照
[1 200~2 000 μmol/(m2·s)]后168 h内叶片叶绿素含量、光合特性、叶绿素荧光参数、叶绿素合成前体物质含量及过氧化物酶活性等进行了测定和分析。结果表明:(1)与低光照相比,高光照处理168 h后,金幌叶片中叶绿素a、叶绿素b含量、超氧化物歧化酶活性、净光合速率和蒸腾速率显著低于粉晶。(2)在低光照时,金幌叶片中的5-氨基乙酰丙酸、胆色素、尿卟啉和粪卟啉等4种前体物质含量均显著高于粉晶,其中粪卟啉含量是粉晶中的2倍。(3)高光照处理168 h后,金幌叶片中非光化学猝灭(NPQ)参数值显著高于粉晶,而PSⅡ原初光化学效率(Fv/Fm)和非循环光合电子传递速率(ETR)则与粉晶差异不显著。说明金幌叶色变化的直接原因是叶绿素含量,特别是叶绿素b含量变化。叶绿素b含量的改变则是由于叶绿素合成前体物质,特别是粪卟啉的累积造成的。叶绿素含量的改变同时导致了金幌光合能力的降低及光合系统PS II的稳定性的改变。
Abstract:
In this study, the acclimation response of crape myrtle (Lagerstroemia indica) Jinhuang and Fenjing plants was assessed during 168 h after transferring from low light [LL, 50-120 μmol/(m2·s)] to high light [HL, 1 200-2 000 μmol/(m2·s)] by analyzing the content of chlorophyll, photosynthetic properties, chlorophyll fluorescence parameters, chlorophyll synthesis precursors contents and peroxidase activity. The results showed that compared with low light treatment, the contents of chlorophyll a and chlorophyll b, superoxide dismutase activity, net photosynthetic rate and transpiration rate of leaves in Jinhuang were significantly lower than those in Fenjing after 168 hours of high light treatment. Under low light conditions, the contents of four precursors including 5-aminolevulinic acid, bile pigment, urinary porphyrin and coproporphyrin in Jinhuang leaves were significantly higher than those in Fenjing, and the content of coproporphyrin was twice as high as that in Fenjing. After 168 hours of high light treatment, the value of non-photochemical quenching (NPQ) in Jinhuang leaves was significantly higher than that in Fenjing, while the differences of initial light energy conversion efficiency of PS II(Fv/Fm) and electron transport rate(ETR) were not significant. This indicates that the change of leaf color in Jinhuang is directly caused by the change of chlorophyll content, especially the content of chlorophyll b. The change of chlorophyll b content is caused by the accumulation of chlorophyll synthesis precursors, especially coprophyrin. The changes of chlorophyll content also lead to the decrease of photosynthetic capacity and PS II stability in Jinhuang.
