摘要:
以克隆植物结缕草为研究对象,通过对连接和断开的母株和子株进行不同营养分水平处理,研究养分异质条件下结缕草克隆分株生长、光合色素及叶绿素荧光特性的变化。结果表明,在养分异质条件下,与处于中、高养分水平的母株相连的子株生物量、叶绿素(Chl.)含量、类胡萝卜素(Car.)含量、潜在最大光化学量子效率(Fv/Fm)、PSII实际光化学量子效率(ΦPSII)、电子传递速率(ETR)和光化学淬灭系数(qP)增高,非光化学淬灭系数(qN)降低;反之,与处于中、高养分水平的子株相连的母株生物量、光合色素含量及叶绿素荧光参数没有显著变化。在养分异质条件下,处于中、高养分条件下的结缕草母株对低养分条件下的子株存在生理整合,养分梯度越大,整合强度越强。低养分条件下的子株可以从中、高养分条件下的母株获益,但低养分条件下的母株不能从中、高养分条件下的子株获益,子株是生理整合单向获益者。
Abstract:
Using the clonal plant Zoysia japonica as the experimental materials, the changes of the growth, photosynthetic pigment content and chlorophyll fluorescence characteristics of clonal ramets under nutrient heterogeneity were studied by treating the connected and disconnected parent and daughter ramets with different nutrient concentration. The results indicated that the parent ramets in middle or high nutrient level could improve the biomass, chlorophyll (Chl) content, carotenoids (Car) content, potential maximum PSII quantum efficiency (Fv/Fm), actual photochemical quantum efficiency of PSII (ΦPSII), electron transport rate (ETR), and photochemistry quenching coefficient (qP) of the connected daughter ramets under the nutrient heterogeneity, but reduce the non-photochemistry quenching coefficient(qN) of the connected daughter ramets. In contrast, the daughter ramets in middle or high nutrient levels had no significant impact on the biomass, photosynthetic pigment content and chlorophyll fluorescence parameters of the connected parent ramets. There existed physiological integration from the parent ramets in middle or high nutrient level to the daughter ramets in low nutrient level, and the larger the nutrient difference of ramets was, the stronger the intensity of physiological integration was. The daughter ramets in low nutrient level benefited from the parent ramets in middle or high nutrient level, but the parent ramets in low nutrient level couldn′t benefit from the daughter ramets in middle or high nutrient level. The daughter ramets were the unidirectional beneficiary from the physiological integration.
