GAO Yu-mei;ZHANG Shu-jiang;ZHANG Shi-fan;LI Fei;WANG Xiao-wu;WU Jian;SUN Ri-fei*
The ITS sequences of 18 different types of Brassica rapa were amplified by PCR and sequenced,and then the NJ tree was constructed by ITS sequences to analyze the variations of ITS sequence.The results show that the sequences of the ITS of Brassica rapa are very conservative,and no variations exist between different types.Brassica rapa has variations with other species of Brassica respectively.The ITS sequences have variations among the species of Brassica,and the different type materials of the basic species of Brassica have no variations.However,those of the complicate species have variations and the ITS sequences tend to the putative parents of the U-triangle respectively.

19 Changes of Physiological and Biochemical Indexes from Budding to Bolting in Spring Cabbage
YANG Xiao-ming;LI Cheng-qiong*;SONG Hong-yuan;REN Xue-song;SI Jun
Taking 2 different spring cabbage(Brassica oleracea L.)varieties‘2006042’and‘Chunfeng’as materials,the paper observes their development process of flower bud differentiation by petrolin sectioncutting method and analyzes the changes in physiological and biochemical indexes during different development stages.The results show that the budding process of bolting susceptible cabbage‘2006042’is about 8 days earlier than that of the bolting tolerant cabbage‘Chunfeng’.The analysis of soluble protein in‘2006042’with SDS-PAGE finds three special protein bands(48.4 kD,18.8 kD,14.5 kD)are expressively re-enforced,and at the same time the band(84.0 kD)is disappeared and the band(17.4 kD)is weakened.This indicates that the above mentioned proteins have very close relation with bolting.The contents of soluble protein content and sucrose in‘2006042’are higher than that in‘Chunfeng’.

24 Effects of Different Potassium Dosage on Aroma Components and Contents in Muskmelon（Cucumis melo L.）Fruit
WANG Rui-zhu;WANG Huai-song;HE Chao-xing*;ZHANG Zhi-bin
Aroma components of muskmelon（Cucumis melo L.）fruits‘Zhongmi No.5’were analyzed by Gas Chromatograph-Mass Spectrometry(GC-MS)treated by 4 different potassium fertilizer dosage applications.The results showed that 4 treatments low-K,middle-K(CK),middle and high-K,high-K contained 32,35,34,39 aroma components,respectively,which represented about 96.78 %,98.39 %,95.27 %,90.95 % peak area of the total.Along with the increasing dosage of potassium fertilizer,the ester and alcohols contents in muskmelon fruit were inverse ratio.The aroma components,such as 3,6-Nonadien-1-ol(E,Z),(6Z)-Nonen-1-ol,(Z)-3-Nonen-1-ol,2,3-Butanedioldiacetate,Butanoic acid,2-methylethyl ester,6-Nonen-1-ol-acetate and 3-Nonen-1-ol,(Z)- had significant differences in relative contents.The aroma components will follow the trend of increasing first then decreasing afterwards along with the increase of potassium fertilizer dosage.The best quality of muskmelon fruit will be achieved by suitable potassium fertilizer treatment(9.6 g per plant).

30 Studies on Seedling Heat Tolerance of Different Eggplant(Solanum melongena L.)Varieties
ZHANG Ya;HE Yong;ZHU Zhu-jun*
This paper studied the effects of high temperature stress(45 ℃/36 ℃,day/night)on 4 eggplant(Solanum melongena L.)varieties and the heat injury index,electrolytic leakage,SOD activity,MDA content and the influence exerted by chlorophyll fluorescence of high temperature stress on these varieties.The results showed that heat injury index,electrolytic leakage rate and MDA content in eggplant seedlings increased significantly after high temperature treatment.The rising rate of heat tolerant varieties was lower than those sensitive cultivars.The SOD activity decreased significantly.After 2 days recovery,the SOD activity of heat tolerant eggplants‘06-E417’and‘Zifei No.1’increased by 20.3 % and 20.7 %,respectively than pretreatment,while those of heat sensitive eggplants nearly remained the same.High temperature stress also decreased Fv/Fm，Fv/Fo，ΦPSⅡ，qP，ETR and Fv’/Fm’in eggplant significantly.But the decreasing rate of heat tolerant cultivars is lower than those of heat sensitive cultivars.This indicates that under high temperature stress,the heat tolerant varieties possess higher activity of PSⅡ.

36 Experiment on the Effect of Inducing Heat Resistance in Tomato Seedlings by Salicylic Acid
WAN Zheng-lin;LUO Qing-xi*;LI Li-zhi
Using salicylic acid of different concentrations to treat tomato(Lycopersicon esculentum Mill.)seedling,and through testing Pro,REC and MDA,this study found the best concentration in inducing heat resistance of tomato seedling was 60 mg·L-1 by spraying salicylic acid on its leaves.The mechanism of using salicylic acid to induce heat resistance of tomato seedling was initially studied.After the salicylic acid was sprayed on the leave surface,where high activity of SOD,POD,APX were maintain under high temperature stress,which helped to reduce the producing and accumulating of active oxygen and reduce the oxidative stress,therefore enhance the stabilization of cell membrane and improve the heat resistant ability of tomato seedlings.In the role of improving heat resistance of tomato seedlings,the activity of CAT is one of the causes for high temperature stress,but inducing heat resistance by salicylic acid might have nothing to do with activity of CAT.

43 Cucumber Leaf Area Genetics and QTL Analysis
WU Peng;QIN Zhi-wei*;XIA Yuan;ZHOU Xiu-yan;WU Tao
Two large leaf area cucumber（Cusumis sativus L.）varieties(D9320,D2005)and two small leaf area cucumber varieties(D0455,D0401)were selected to build a hybrid combination.A parental combination with bigger leaf area difference D0401×D9320 was screened to build up self-isolated groups of F2 generation.Genetic analysis was conducted by using additivedominance(AD)model.The results showed that cucumber leaf area was a quantitative trait controlled by multi-genes.It took dominant effect as main character,and there were certain additive effects with higher narrow-sense and broad-sense heritability.SSR molecular markers were adopted to build genetic linkage map,using composite interval mapping methods for QTL location of cucumber leaf areas.The results showed that CSWACC03,CSWCT05BZ and CSCTTT15a were located on the same linkage group.The total length of linkage group was 68.3 cM.One QTL was detected in connection with cucumber leaf area.Its distance to the nearest marker was 3.6 cM and the contribution rate to mutation was 8.65 %.

ZHAO Sheng-jie;LIU Wen-ge*;YAN Zhi-hong;HE Nan
5 034 non-redundant ESTs of watermelon〔Citrullus lanatus(Thunb.)Matsum.et Nakai〕were screened and 347 SSRs were mined out.The frequency of these EST-SSRs was 689 % and the mean distance was 7.49 kb in non-redundant ESTs.All these SSRs included 91 kinds of repeat motifs.Among them the dinucleotide and trinucleotide repeats were dominant types,accounting for 39.48 % and 46.68 %,respectively.AT is most frequent motif in dinucleotide accounting for 23.35 %.The distribution of trinucleotide repeats was dispersive and the dominant motif was GAA,only accounting for 8.64 % in all the trinucleotide repeats.The EST-SSRs are highly feasible in theory.
