- 摘要:
- 以广西木莲为试材，采用不同的干旱强度，正常供水CK(土壤水分含量为最大田间持水量的80%，下同），轻度干旱胁迫P1（65%）、中度干旱胁迫P2（35%）、重度干旱胁迫P3（15%）4种处理方式对广西木莲抗旱能力进行研究，对广西木莲叶片光合指标和叶绿素荧光值进行分析。结果表明：随着干旱强度的增强，广西木莲的光合作用能力不断降低，Pmax、Tr、Gs等光合指标不断下降。但Ci在P2处理条件下达到最低，植物细胞获取CO2能力逐渐稳定，表现出了广西木莲较弱的抗旱能力；在对叶绿素荧光日变化值研究发现，Fv/Fm、ΦPSII具有随着光照日变化会自我恢复到一个稳定值，表明了广西木莲在逆境条件下能够维持植物体内一定的光合作用，保证植物体自身的能量获取。
- Abstract:
- Taking Manglietia tenuipesa as material，the effects of the normal water supply CK (soil moisture content was 80%)，mild drought stress (P1:65%)，moderate drought stress (P2:35%)，severe drought stress (P3:15%) four different drought intensities to coercion Manglietia tenuipesa were studied，and photosynthesis and chlorophyll fluorescence value of Manglietia tenuipesa leaves was analyszed.The results showed that with the enhancement of drought intensity，Manglietia tenuipesa photosynthetic capability decreased，Pmax，Tr，Gs and other photosynthetic indexes falled.But Ci reached the lowest in P2 treatment，the ability of obtaining CO2 of plant cell stabilized gradually，and it’s showed the drought resistance ability of Manglietia tenuipesa was weak；it’s found that，Fv/Fm，ΦPSII with the changing of light，which should be recovered to a stable value，showed Manglietia tenuipesa could maintain a certain level of photosynthesis in plants under stress conditions，ensure the plant body to gain energy.
