  A pair of oligonucleotide primers was designed from conserved domain of EIN3 gene family.PCR amplifications were performed on different sex genotype cucumber DNA template and produced 6 fragments of 725 bp，respectively.After cloning and sequencing on CsEIN3 of different sex genotype cucumbers，BLAST and DNAMAN analysis found 14 single nucleotide polymorphisms（SNPs）in coding region，about one average 51 bp，selection rating 1.96 %，3 mutation in enzyme digested site，eight SNPs mutation cause amino acid sequence variation.One set of stable RFLP-BfmⅠenzyme digested reaction system was established.By digesting DNA from different sex genotypes，a specific enzyme digest band in WI1983H was found.

  AFLP and morphological analysis were carried out on 33 radish（Raphanus sativus L.）germplasms.Eight primer combinations were selected for using in characterizing the radish collection.Differences in number，intensity，and size of amplification products were observed depending on the primer combination，ranging between 35 and 56 bands per pair with an average of 45.2 bands.The polymorphism rate was 42.10 %，which indicates abundant genetic diversity existing among the cultivated radish germplasms.These germplasms were clustered into four groups by morphological analysis and AFLP，respectively.Rs14 was single in one cluster which suggests it is a unique germplasm for its purple flesh.The clustering patterns of other materials for AFLP and morphological data were similar.And in general，the others were divided into three groups according to their skin colors：green radish，white radish and red radish.

  The experiment was performed to study the effects of exogenous ABA on Na+Cl-，K+，Ca2+ contents in different organs of cucumber（Cucumis sativus L.）seedlings under NaCl stress.Results showed that Na+ and Cl- contents increased while K+ and Ca2+ contents of leaves decreased，Na+/K+ and Na+/Ca2+ increased，SK、Na and SCa、Na decreased in NaCl-treated cucumber seedlings.Cucumber seedlings treated with exogenous ABA combined with salinity showed higher levels of K+ and Ca2+ accumulation of leaves and lower levels of Na+ and Cl- accumulation of leaves and root.Exogenous ABA could improve the absorbing selectivity of K+ and Ca2+，thus to enhance the salt tolerance of cucumber seedlings.
