1 Research advance in the toxicity and residue of plant growth regulator in vegetables in China
Xu Ai-dong
Toxicity, the present residual state and residue limit standards of several used plant growth regulator in vegetables were reviewed in this paper. Some methods of reducing toxicity residue, as well as suggestions of using plant growth regulator effectively were discussed. It was necessary to reduce toxicity residue of plant growth regulator and improve food safety in vegetables in our country.

11 Identification of seawater-tolerance spinach cultivar and selection of its form index
LI Zhi-hai;SUN Jin;LI Juan;GUO Shi-rong
Exposed to 8 concentrations of seawater, 14 cultivars of spinach were investigated in solution culture in order to identify seawater-tolerant cultivar and select appropriate identification index. The results showed that the cultivar of ‘Helan No.3’ was tolerance, ‘Faliancao168 qianglibocai’has middle tolerance and the other cultivars were sensitive to seawater.The appropriate identifying concentration was 40%, and the relative value of dry weight, fresh weight, leaf area, survival leaf number were credible indexes for identification, but salt injury index may be also used as an identification index in range of certain concentration. However, relative water-content of leaf and root/shoot were improper indexes for identifying spinach seawater-tolerance.

YU Xiao-lin;YE Yu-xiu;PANG Run-jin
Effects on seed germination,seedling growth and root morphology in cucumber were studied by treatments of Cd,Pb. The results showed that the seed germination indices,shoot and root fresh weight of cucumber decreased with increasing concentration of Cd、Pb.The total root length、total surface area of cucumber roots were decreased with increasing concentration of Cd,Pb also.the average diameter of cucumber roots were increased with increasing concentration of Cd,Pb under the low consistence, but were decreased obviously under the high consistence.The single effect of Cd on cucumber seed germination and roots was obvious than that of Pb．‘Yuyi201’ cucumber was more tolerant to Cd and Pb than ‘Jiangshulufeng’ cucumber.

23 Effects of seed soaking with PEG on physiology indexes in leaves of pepper seedlings under low temperature and poor light
LI Ying;XIE Jian-ming;WANG Zhi-wei;YU Ji-hua;FENG Zhi
The changes of some physiological indexes were investigated in seedling leaves of ‘Xiangyan No.1’ pepper under low temperature and poor light stress with 25% concentration of polyethylene glycol (PEG) solution seed soaking. Significant increases in membrane permeability, malondialdehyde (MDA) and proline (Pro) contents, decreases in soluble protein and dry weight of aboveground, dry weight of underground, plant height and stem diameter were observed in leaves of pepper seedlings under low temperature and poor light 15℃/5℃(day/night),100μmol·m-2·s-1. The SOD and POD activities increased and arrived at highest value on the 4th day, then decreased in leaves of pepper under low temperature and poor light stress.Compared to the control, the increment in membrane permeability, MDA and Pro contents were smaller, and the reducement in activities of SOD and POD, contents in soluble protein, dry weight of aboveground, dry weight of underground, plant height and stem diameter were smaller in leaves of pepper under low temperature and poor light stress with PEG seed-soaking. These results suggested that PEG seed-soaking could increase the resistance ability to low temperature and poor light stress of pepper seedlings.

28 Analysis on evaluation method for cucumber fruit bending and relativities
GE Chang-jun;QIN Zhi-wei;ZHOU Xiu-yan
This paper takes 48 cucumber varieties as experiment material, and adopts cutting method to measure cucumber fruit bending degree. Through relative analysis, we find bending has very significant positive correlation with length、stalk length、stalk length/fruit length、fruit length/ fruit diameter ,and very significant negative correlation with cavity size、cavity/ fruit diameter and significant negative correlation with fruit diameter. But it is irrelevance with flesh thickness .According to fruit shape index and bending degree, the paper carries out grading on cucumber and selects 8 straight species and 31 bending varieties.

32 Isolated microspore culture and plantlet regeneration in yellow heading spring Chinese cabbage
PAN Hong-yan;FENG Hui
Isolated microspore culture was carried out with 14 F1 yellow Chinese cabbage introduced from South Korea and Japan. Frequencies of embryogenesis, factors influencing the plantlet regeneration were studied. Results showed that genotypes had extremely significant effect on frequency of embryogenesis. The reaction of genotypes to growth regulators added in the medium was different. Liquid culture in condition of 40r·min-1 oscillation could promote the development of the embryoids.Optimal medium for shooting is embryoids was MS + 2.0mg·L-1 6-BA + 0.1mg·L-1 NAA + 3%sucrose + 0.8% agar.

QI Jian-jian;LIU Shi-qi;ZHANG Zi-kun;WEI Hui;DUAN Jifeng;CHEN Kun;ZHANG Min
A field-trail experiment was carried out to investigate the effects of single basal application of controlled-releasing bulk blending fertilizer(CRF) on yield、quality and nitrogen utilization efficiency of two garlic cultivars:‘Cangshansuan’ and ‘Jinxiangsuan’. Results showed that compared to CCF, 100% and 80% CRF treatments could increase bulb yield、bulb soluble sugar content and SOD activity significantly by 5.0%-12.5% and 15.0%-15.8%, 3.5%-27.6% and 15.1%-30.0%, 48.1%-93.2% and 61.0%-68.4% for each cultivar, respectively. What was more, 12.5%-20.5% and 31.8%-37.3%, 86.4%-87.0% and 146.0%-171.5% higher plant dry matter yield and nitrogen utilization efficiency were also observed in these two specific treatments. However, 60% CRF application showed no promoting effect on the factors mentioned above. Difference of VC content between CRF and CCF treatments was no significant. Allicin content exhibited a negatively correlation with bulb yield. In order to ensure garlic flavor and quality, an extra S input should be performed together with CRF.

WANG Heng;JING Sheng’ai;LI Junliang;LIU Qinghua;CHEN Yongzhi
The field experiment with '3414' design (CK,N0P0K0,MN2P0K2,MN2P1K2,MN2P2K2,MN2P3K2,MN2P2K0,MN2P2K1,MN2P2K3 and MN0P0K0) was conducted in Shandong Shouguang in order to investigate the effect of P and K fertilizer on facility tomato. The results showed that the treatment of MN2P1K2 got the maximum yield, which was 160.86 t·hm-2, 7.2% higher than the traditional treatment. In addition, P application on tomato had no effect or even decreased yield with high soil available phosphorus level. Appropriate organic manure with decreased phosphorus supply was an effective method to increase tomato yield.The effect of potash fertilizer was not remarkable in early growing period, so potash fertilizer should be supplied less in this period and later more in the mid-late growing period.

54 Effects of different copper agents on growth of chilli
SONG Rui-lei;ZANG Min;HOU Xiao-lin;WANG Hui
Pot experiments were conducted to study the effects of spraying three kinds of copper agents: Bordeaux Mixture(BDM), Kocide2000(KCD), Bordeaux Nutritional Protective Powder(BNPP)，on surface of chilli leaves with different concentrations. The results showed that spraying BNPP at certain intervals significantly increased the yield of the chilli, and two different concentrations of BNPP increased the yield by 74.7% and 26.7%, 59.4% and 15.6%, respectively, as compared to the control. Compared with the spraying concentration of 2 g•L-1，, the concentration of 1 g•L-1， received better results in the treatments. In comparison, the treatments with spraying KCD at different concentrations promoted the growth of chilli as well, though unparalleled with the BNPP. However, the spraying of BDM inhibited the growth of chilli in leaf area and the content of chlorophyl.

QI Zhi-qiu;LI Xing-hai;WANG Ying-zi;WEI SONG-hong;GU Zu-min;JI Ming-shan
Colonizing of B67 isolate marked with Rifampicin on the soil and rhizosphere of cucumber were investigated. The results showed that B67 could be colonized in soil. Population of B67 isolate declined with prolonging time and received 0 after treatment 31days. Cucumber varieties had not significant effect on colonizing population of B67 isolate. B67 isolates were detected in rhizosphere of cucumber and the population of B67 isolate decreased as time went by, while it could still be detected at the 20th day after the treatment.
