The Citric acid dehydrogenase( CDH)in leaves of 5 0 plants from 5 small populations with differ-ent altitudes and habitats of the endangered species Deutzia multiradiata, endemic to Mt.Jinfo ofNanchuan,China. Was studies with sreat care according to the eletrophoretic technique. The bandsof CDH are scored to construct the two-state data matrix which is calculated by Rogers-Tanimoto,Kulezynski,Czekanowski and Jaccard association coefficients with UPGMA and WPGMA respectivelyfor the anal yses of that isozymic differentiat ion among individuals and populations of Deutzia multiradia-ta. The result reveals the there are vivid variabilities on the CDH bands not only among individuals butalso among populations,even rich among the individuals wthin the same population,which indicatesthat we cannot choose the CDH bands of one or geveral individuals to kepresent the studieds pecicswhen its taxonomy and interspecific affinities were interprated. The CDH bands show diffe rentiationsto some extent among diferent populations and individuals from the same micro-population are more orless clustered,while individuals from the different micro-populations show certain dlssimilarities inisozyme bands,Dis clear that the CDH bands of a given nucro-population are somewhat correlatedwith the habitat from which it was colllected,Certain micro-populations pcasess some unique CDHbands,which can be explained by the distribution pettern and reproductive features of the species,Itdistributes as scattered micro-populations which are isolated each other spatially. Such spatial isolationlargely inhabites the gene exchange among individuls from diferent micro-populations and those adapt-ed genetic variations to these micro-habitas are selected and remained in the evolutionary process,which makes the genetic divergence among micro- populations becomming more obvious. The micro-habitats here only play the role in selecting that habitat.The remarkable hybridizations among individu-als of the same population lead to more easily gene exchange and can enrich the genetic heterogeneitywhthin the same population, which can be regarded as the genetic variation resource that will be benifi-cial for the survivorship of the endangered species as D. multiradiata.

Fifteen natural populations representing all the taxa in Adenophora potaninii complex were investigated using vertical slab polyacrylamide gel electrophoresis. Allozyme data for ten loci of seven enzymes demonstrate high levels of genetic variation within populations, with the values of P=0 40~0 70, A=1.5~2.5 and He=0.102~0.291. At specific level, there existed the highest variation in A. wawreana (A=2.10, P=0 63, He=0.237), followed by those of A. lobophylla (A=1.85, P=0 60, He=0.204) and A. potaninii (A=1.83, P=0 60, He=0.188). Based on Wright's F statistics, the outcrossing rates(t) were 0.86(A. wawreana ), 0.74 (A. potaninii) and 0.63(A. lobophylla). The analysis on population genetic structure indicates that most variation resided within populations, which is consistent with the high rate of outcrossing rates in the complex. On the basis of genetic identity(I), cluster analysis shows that there was high genetic divergence between A. lobophylla populations and A. wawreana A. potaninii clade, while no clear genetic difference was found between A. wawreana populations and A. potaninii populations. Consequently, the present allozyme data justify the establishment of A. lobophylla, but give no support for treating A. wawreana and A. potaninii as a separate species.

The C-banding patterns in 8 populations of Paeonia delavayi var. lutea were investigated by using a modified BSG technique. Each population examined here showed there were C-bands at the centromeric regions of all ten chromosomes. However, C-bands were not observed on long arms of any chromoseme. There are differences in the C-band numbers and positions in the terminal regions on the short arms. In Ludian population, C-band occupies one terminal region on the short arms of the first and 4th pairs of chromosomes respectively, which means the homologous chromosomes of the first and 4th pair of chromosomes are heterogeneous. Each population has the unique C-banding pattern except two populations of Xishan and Liangwangshan, which share the same C-banding pattern. Namely, there are 7 C-banding patterns in 8 populations examined here. The diversity of C-banding patterns indicated that the genetic diversity occurs in P. delavayi var. lutea.
