摘要:

为筛选适宜山东地区栽培的麻栎优良种源,本研究以山东泰安、青岛、莱芜、烟台、临沂5个地区的麻栎幼苗为材料,系统分析了其种子形态特征(种子长、种子宽、百粒重、长宽比)和幼苗生长指标(苗高、地径、生物量分配)。结果表明,生物量与生长指标在不同种源间差异显著(p0.05),呈现出明显的地理变异;根冠比在种源间无显著差异,表明麻栎在不同地理环境下仍维持相对稳定的生物量分配模式。种子性状中,种子长度最为保守,百粒重变异较大。总体而言,烟台和青岛种源幼苗整体生长较好;莱芜种源在大多数生长指标上表现较差。以上研究结果为麻栎优良种源选择和区域化栽培提供了科学依据。

Abstract:

To select superior provenances of Quercus acutissima suitable for cultivation in Shandong Province,this study used seedlings from five regions in Shandong(Tai'an,Qingdao,Laiwu,Yantai,and Linyi)as experimental materials,and systematically analyzed their seed morphological characteristics(seed length,width,100-seed weight,and length-width ratio)and seedling growth indicators(seedling height,basal diameter,and biomass allocation). The results showed significant (p0.05) differences in biomass and growth indicators among provenances,revealing obvious geographical variation. However,there was no significant difference in the root-shoot ratio among provenances,indicating that Q. acutissima maintains a relatively stable biomass allocation pattern across different geographical environments. Regarding seed traits,seed length was the most conservative,while 100-seed weight showed substantial variation. Overall,the Yantai and Qingdao provenances exhibited better seedling growth performance;whereas the Laiwu provenance performed poorly in most growth indicators. These findings provide a scientific basis for selecting superior provenances and regionalized cultivation of Q. acutissima.
