It greatly reduces the problem of sparsity of data, because the size of the vocabulary made up of characters is smaller than that formed from words.
由于字的数量远小于词的数量,所以该分类方法与其它在词级别上的分类方法相比,有效地降低了数据稀疏带来的影响。

The results above showed:(1) The cultivars of large-flowered chrysanthemum are widely distributed in Beijing area with plentiful floral types and floral colors;(2) The cultivars with the rare types and colors are urgent for protection;(3) Most of the quantitative characters obeys to the normal distribution,some important traits agreed with skewed distribution.The probability grading can assist quantitative character in establishing new grading standards;(4) Most of qualitative characters is asymmetrical in cultivars,which might be caused by unbalanced differentiation of characters or linkages coming from emphasis characters selection;(5) The floral characters are relatively stable and have comparably large influence on classification,the characters of stipule also have a certain degree of stability and can act as an reasonable supplement for cultivars classification,but the foliar characters have worse stability and can only be recognized as lower level criterion.(6) The genetic relationship among the Flat-petaled group,the Quilled-petal group and the Spoon-petaled group are closest,which followed by the Filiform-petal group because of long-term selection pressure for the specialization of the petal tip loved by most people.The Anemone-petal group has further genetic relationship with these four groups.(7) ISSR molecular marker detection indicates that the proportion of polymorphic loci of lardge-flowered chrysanthemum is higher,in which the Flat-petaled group has the highest genetic diversity level.
综合以上的研究结果表明:(1)北京地区现有大量大菊品种,且花型与花色较为丰富;(2)珍稀花型、花色品种亟需保护;(3)大部分数量性状是符合正态分布的,少数重点观赏性状迫于选择压力呈现偏态分布,概率分级法能够辅助大菊的数量性状建立新的分级标准;(4)大部分质量性状在品种群内的分布是不均匀的,可能是由菊花性状遗传分化的不均衡性或受到选育重点性状的连锁作用而造成的;(5)大菊花部性状相对稳定,对品种分类影响较大,其托叶部分也具有一定程度的稳定性,可以作为品种分类的合理补充,而叶部性状稳定性较差,在品种分类中应作为更次一级的分类依据;(6)平瓣类、管瓣类和匙瓣类的亲缘关系最近,畸瓣类品种花瓣先端特化受到人们的喜爱,长期的选择压力使其区别于3种基本瓣型,而这四种瓣型与桂瓣类在亲缘关系上较远;(7)ISSR分子标记检测表明:大菊品种多态性位点百分率较高,平瓣类品种的遗传分化最为丰富。

结果表明,除人为干扰比较严重的生境外,基株大小与匍匐茎数量、单位长度匍匐茎干重之间存在极显著的正线形相关(P〈0.01),基株大小对分株的影响可能与匍匐茎数量有关;匍匐茎与分株总干重与基株干重的比值在海拔最高和最低两个样地中最大。
