摘要:

本文运用数量分类学的原理和方法,分析了柑桔83个生物型叶片可溶性蛋白质电泳谱
带的相似性。对属、种内的部分生物型的相似性进行了比较, 探讨了金柑属在柑桔分类中的地
位, 对一些起源不明的生物型的可能祖先作了推断。从叶片蛋白质谱带相似性聚类分析树系
图上,可发现柑桔由枳到柑亚类的大致进化趋势, 作者认为,将宜昌橙归入大翼橙类要更加合理。

Abstract:

Soluble proteins were extracted from mature leaves of 83 citrus biotypes.  Their
protein patterns were obtained by acrylamide gel electrophoresis.  The similarity of the protein
patterns among the samples was calculated by computer according to the principle and me-
thods of numerical taxonomy.
     The similarity comparison was made between different species and varieties included in
the Swingl’s system.  The distance coefficients of similarity (DCS) is 2.13 between species in
the genus Citrus, 0.927 in Poncirus and 0.617 among Fortunella species.  The DCS of biotypes
in Citrus limon, C. paradisi and C. sinensis are zero, and those in C. grandis and C. reticulata
are 0.656 and 0.863 respectively.  There is no difference among satsuma mandarin, Tankan and
King mandarin, which are considered respectively as a good species in Tanaka’s system.
     Ancestors of some biotypes. whose origin was unknown berore, are postulated in this work.
Jiang Bai Shang Cheng is probably a hybrid between C. junos Tanaka and mandarin, rough
lemon may be a hybrid of mandarin with citron or lime, but not with lemon.  Some so-called
lemon biotypes are not in the same cluster as true lemon (Eureka or Lishon).  The biotypes.
of sour orange, all of which are scattered in the phenetic tree of cluster analysis (PTCA), might
have been derived from different ancestors.
      In the PTCA the evolutionary tendency from Poncirus to Macroacrumen in the citrus plants
may be found on the basis of the DCS of different genera, sections and subsections respec-
tively with the subsection Macroacrumen.
      The present author considers that if Fortunella is recognized as true genus, Cephalocitrus
should also be an acceptable genus.  The position of Fortunella in the PTCA is between the
sections Cephalocitrus and Aurantium, but it does not represent its position in the phylogeny.
Taking comprehensive data into consideration it appear to be more reasonable to place C. ichan-
gensis, as member of Papeda originated in the subtropics, in the section Papeda.
