不同年龄瑞香狼毒的根水提液对青藏高原高寒草甸4种常见植物的化感作用
, 2017 瑞香狼毒是我国主要的草地毒害草,也是青藏高原高寒草甸危害最为严重的草地毒害草之一。已有研究表明,狼毒根系及其器官具有化感作用,但是对不同年龄狼毒植株化感作用的差异尚未见报道。研究选取2个年龄段(3—5龄与8—10龄)的狼毒植株,对比研究了其根系水提液对4种高寒草甸常见植物垂穗披碱草(Elymus nutans)、歪头菜(Vicia unijuga)、草玉梅(Anemone rivularis)、川西翠雀(Delphinium tongolense)种子和幼苗生理与生长的化感作用。结果显示 ...

, 2001 两观测者独立观测了分别采自洪湖的 1 75尾和洞庭湖的 1 6 8尾鲫样本的鳞片和耳石 ,结果显示鳞片适于鉴定年龄组成简单、生长较快的洞庭湖鲫种群的年龄 ,两观测者年轮读数的总吻合率可达 90 5% ,与耳石上年轮读数的吻合率也可高达 91 7% ;但用鳞片鉴定年龄结构复杂、生长缓慢的洪湖鲫种群年龄 ,两观测者总吻合率只有 50 9% ,各龄组吻合率随年龄上升而迅速下降 ,与耳石上年轮读数总吻合率也仅为 56 6 % ,存在比耳石低估高龄个体年龄的问题。用耳石鉴定鲫年龄具有易于识别、精确度高的优点 ...
