標記技術對樺樹種間親緣關系的分析Phylogenetic analysis surports that anseranas should be placed in monotypic family anseranatidae, and the whistling ducks and the white - backed duck should be separated from subfamily anserinae and placed them into family dendrocygnidae. the family anatidae could be classified into two subfamilies, anserinae and anatinae. the results approve that the swans should be put into the tribe cygnini of subfamily anserinae as suggested by livezey ( 1996, 1997b ) and the shelducks should be placed in the tribe tadornini of subfamily anatinae, therefore, our results do not support sibley and ahlquist ' s ( 1990 ) establishment of the subfamily cygninae and placing the shelducks in the tribe anserini
研究結果表明： 1 ）雁形目鳥類12srrna基因有較多的堿基插入和缺失，堿基轉換數高於顛換數； 2 ）贊同將鵲鵝（ anseranas ）置於鵲鵝科（ anseranatidae ）中，樹鴨（ dendrocygna ）應從雁亞科（ anserinae ）中獨立出來設立樹鴨科（ dendrocygnidae ） ，白背鴨（ thalassornis ）隸屬于樹鴨科； 3 ）鴨科（ anatidae ）可分為雁亞科和鴨亞科（ anatinae ） 2個亞科，不贊同sibley & ahlquist （ 1990 ）設立天鵝亞科（ cygninae ）及將麻鴨歸入雁族（ anserini ）的觀點，支持livezey （ 1996a ， 1997b ）的觀點建議將天鵝類歸為雁亞科天鵝族（ cygnini ） ，麻鴨置於鴨亞科下麻鴨族； 4 ）在鴨亞科內的系統發生上，潛鴨最早分歧出來，麻鴨、海中文摘要鴨及棲鴨彼此iaj的親緣關系較近；河鴨族為一單系發生群，在系統演化中形成獨立的一支。Through the studies on the anatomical configuration of eight different interstocks apple ( red fuji ) branches using microscope and vernier caliper, we can show that the pith proportion was positive correlative with the growth potential of apple tree if they have close kin
