摘要:
2016 年对1 年生华顶杜鹃Rhododendron huadingense 幼苗接种杜鹃花类菌根(ERM),测定其对叶绿素含量和光合特性的影响。结果显示,接种苗的叶绿素含量高于对照(未接种),接种苗的叶绿素a/b 在弱光下(二层遮荫和三层遮荫)低于对照苗,表明接种ERM 有利于华顶杜鹃幼苗捕获光能和对弱光的利用;接种苗的净光合速率(Pn)、气孔导度(Gs)和蒸腾速率(Tr)均比对照苗的高,接种苗的光能利用效率(LUE)和水分利用效率(WUE)也比对照苗的高,而胞间CO2 浓度(Ci)比对照苗的低;一层遮荫处理的接种苗Pn,Tr 和Gs 等指标值最大。表明接种ERM 可提高幼苗利用弱光的能力,并增强对强光的抵抗能力。同时,接种苗的表观量子效率(AQY)和最大光合速率(Pnmax)比对照苗的大,而光饱和点(LSP)、光补偿点(LCP)和暗呼吸速率(Rd)比对照苗的小,也表明接种ERM 可提高幼苗的光合能力、降低在中强光照下的暗呼吸。试验表明,接种EMR 有利于华顶杜鹃幼苗捕获光能,增强其对强光照和弱光照环境的适应能力。
Abstract:
Experiments were conducted on inoculation of Ericoid mycorrhiza (ERM) to 1-year Rhododendron huadingense seedlings in 2016.Determinations were implemented on chlorophyll content and photosynthetic properties under different light intensities of inoculated seedling andcontrol (no inoculation). Results showed that chlorophyll content in inoculated seedlings was higher than that in the control, and chlorophyll a/b waslower under two shading covers and three shading covers, indicating that treated seedlings could better capture and use light energy under low lightcondition. Net photosynthetic rate (Pn), stomatal conductance (Gs), transpiration rate (Tr), light using efficiency (LUE) and water using efficiency(WUE) was higher in the inoculated seedlings than that in the control, while intercellular CO2 concentration (Ci) was lower. Pn, Tr and Gs of seedlingsunder one shading layer was the maximum, showing that inoculation could increase capture of light. The apparent quantum yield (AQY) andmaximum net photosynthetic rate (Pnmax) was higher in the inoculated seedlings, while the light saturation point (LSP), light compensation point (LCP)and the dark respiration rate (Rd) was lower. The experiment demonstrated that inoculation of ERM on R. huadingense seedlings could improve theefficiency of photosynthesis and reduce Rd under moderate light intensity.
