摘要:
为探讨银叶树幼苗光合作用和叶绿素荧光在不同干旱胁迫下的响应和适应能力,进一步揭示银叶树的抗旱机制,以1.5年生银叶树幼苗为研究对象,采用盆栽控水试验,设置对照(CK)、轻度干旱(LS)、中度干旱(MS)、重度干旱(SS)4个处理,测定银叶树幼苗的生长指标、相对叶绿素含量(SPAD值)、光合生理指标及叶绿素荧光参数,分析其变化规律。结果表明,与CK相比,LS处理对银叶树幼苗生长、光合生理特征及叶绿素荧光参数均无显著影响;MS和SS处理均显著降低了银叶树幼苗的生长量、SPAD值、个体叶片数量、最大净光合速率(Pn,max)、表观量子效率(AQY)、光饱和点(LSP)、实际光量子效率(ΦPSⅡ)和电子传递速率(ETR)(P<0.05),且在SS处理下各指标降低幅度更大;光补偿点(LCP)和非光化学猝灭系数(NPQ)两者则在历经MS、SS处理时显著升高(P<0.05);银叶树暗呼吸速率(Rd)、初始荧光(F0)及最大光化学效率(Fv/Fm)在不同处理下差异不显著。银叶树叶片通过调节光合效能来适应干旱逆境,LS和MS处理对银叶树幼苗的正常生长影响较小,表现出一定的适应性,在SS处理下,银叶树幼苗正常生理代谢受到较严重的影响。
Abstract:
This study aimed to explore the responses and adaptability of photosynthesis and chlorophyll fluorescence of Heritiera littoralis seedlings to different drought stresses and reveal their drought resistance mechanism. A pot experiment was conducted by manipulating drought treatment at four levels, i.e., control(CK, 75%-80% of the maximum soil water holding capacity), light drought stress (LS, 55%-60% of the maximum soil water holding capacity), medium drought stress (MS, 35%-40% of the maximum soil water holding capacity), and severe drought stress (SS, 15%-20% of the maximum soil water holding capacity). The growth index, relative chlorophyll content(SPAD value), photosynthetic physiological characteristics, and chlorophyll fluorescence parameters of H. littoralis seedlings were measured. The results showed that compared with CK, seedlings under LS treatment did not show significant differences in terms of growth, photosynthesis, and chlorophyll fluorescence. The growth of seedlings, SPAD value, leaf number, maximum net photosynthetic rate(Pn,max), apparent quantum yield(AQY), light saturation point(LSP), actual quantum efficiency(ΦPSⅡ), and electron transfer rate(ETR) were significantly reduced under MS and SS treatments(P<0.05). The decline effect was more evident under SS treatment. The light compensation point(LCP) and non-photochemical quenching coefficient(NPQ) showed a significant upward trend under MS and SS treatments(P<0.05). There were no significant differences in the indicators of dark respiration rate(Rd), initial fluorescence(F0), and maximum photochemical efficiency(Fv/Fm) among different drought stresses. These results indicate that H. littoralis seedlings were able to adapt to drought stress by regulating photosynthetic efficiency when under LS and MS treatments, whereas under SS treatments, their normal physiological metabolism was evidently disrupted.
