查询词典 morphological botany

Ecological analysis of morphological and genetic variation revealed that:(1) The averages of morphological characters were significantly negatively correlated with WSF (2) Dominant frequencies of some RAPD loci were significantly correlated with WSF (3) The correlation between morphological variation and genetic variation was not significant (4) The cluster analysis based on morphological and genetic evidence supported that all population can be divided into three ecotypes: saltmarsh reed, freshwater reed and giant reed.

相关分析表明：种群内各形态特征的平均值均与水盐联合影响因子显著负相关，但种群内形态变异系数与水盐联合影响因子普遍相关不显著；种群遗传多样性指数与水盐联合影响因子相关不显著，但部分生境倾向型的RAPD位点的显性频率和来自等位酶分析的克隆多样性水平与水盐联合影响因子显著相关；形态变异系数与遗传多样性指数相关不显著，但相关系数均为正值。

The basal diameter, height of aerial stem, leaf length at middle stem, leaf width at middle stem, internode length at middle stem, internodes number and panicle length of 30 plants from every population were recorded. The statistics of morphological characters showed that the distribution trends of the averages of morphological characters are similar among populations. However, the coefficients of variation within population of 7 morphological characters were very different. The CV of internodes was largest and the CV of height was smallest within population. F-statistics showed that the differences of all morphological characters among populations were significant (P.01). But the differences among populations were different between different groups. The cluster analysis proved that all populations could be divided into three types: salty reed, freshwater reed and giant reed.

对来自每个种群的30个个体的基径、株高、中部叶长、中部叶宽、中部节间长、节间数、穗长7个形态特征的统计分析表明：各形态特征平均值在种群间的分布趋势相似，但变化幅度不同，株高、叶长等营养特征变化较大大，生殖特征穗长的变化较小；7个形态指标在种群内的平均变异度从大到小依次为中部节间长、中部叶宽、穗长、中部叶长、基径、节间数、株高，种群内的平均形态变异度与生境异质性有关；7个形态指标在种群间均差异显著，但多重比较分析显示显著差异主要存在于BZH、淡水生境种群和盐渍化生境种群之间，在相似生境种群间的形态差异不显著；以形态特征为依据的聚类分析支持将15个种群分为三类：盐生芦苇、淡水芦苇和巨型芦苇。

An algorithm of edge detection combined with morphological filter is proposed, firstly, it adopts adaptive method to decide the wimble structuring element and applies iterative morphological filter based on two wimble structure elements to filter the image, then uses multi-scale morphological edge detector to get multi-scale edges, and obtains the more ideal image edges under the environment of existing noise by integrating the edges of various sizes.

文中提出了一种结合形态学滤波的边缘检测算法，该算法采用自适应方法确定锥形结构元素，然后利用双锥形结构元素对图像进行形态学迭代滤波，对滤波后的图像进行多尺度形态学边缘检测，并将各尺度下边缘检测的结果进行合成，最终得到在噪声存在条件下较为理想的图像边缘，并且与其它边缘检测算法进行了对比实验，实验验证了该算法的可行性和有效性。

Botanical experiments are one of important parts linked to the theoretical study of Botany. Through the experiments, students are required to understand the basic theory, knowledge and skills in relation to botanical experiments and study of plants. With the methods and skills learned, students are expectedto have the ability to study the morphogenesis and structure of plant organs in plant ontogenesis as well as morphological characteristics of main plant groups, representative plants, and their positions in plant kingdom and evolution in phylogeny.

植物学实验是植物学理论联系实际的重要课程之一，通过对本课程的学习，要求学生掌握植物学实验的基本理论和基本知识，以及研究植物的一些基本方法和基本技能，并运用这些方法和技能去研究植物个体发育中植物器官的形态建成与结构；学习植物系统发育过程中植物界各大类群主要的形态特征、代表植物，它们在植物界中的地位及演化规律。
