Taking 3 pepper（Capsicum frutescens L.）varieties with peel colors of purple（‘245’），green
（‘246’），white（‘247’） as parents，this study crossed‘ 245×246’ and‘ 245×247’，then constructed 6
generations of genetic population. And by adopting visual grading plus chromatic meter analysis to measure the
L value，C value and color value of single commodity pepper plant peel color during maturity on generations of
P1，P2，F1，F2，B1 and B2. Their peel color inheritances were studied by the method of conjoint analysis on 6
generations. The results showed that the inheritance of fruit peel color traits of commodity maturity accorded with
the nucleus of genetic，and the major gene and polygene（D-2 model）inheritance of fruit peel color of commodity
maturity in the purple-green combination accorded with the additive and hybrid additive-dominance pattern，
that was D-2 model. Its L value，C value and color value of major gene heritability in F2 of the purple-green
combination were 22.39%，91.39% and 82.26%，respectively. The major gene and polygene（E-0 model）
inheritance of fruit peel color of commodity maturity in the purple-white combination accorded with the additivedominance-
epitasis pattern.Its L value，C value and color value of major gene heritability in F2 of the purplewhite
combination were 87.02%，94.34% and 97.54%，respectively. These results indicated that the major gene
heritability in F2 was stronger，while the polygene heritability and environmental effect were weaker. So the fruit
peel color of commodity maturity breeding should be selected in the early generation.
In order to explore the model for effective water and fertilizer utilization in facility vegetable
production，this paper studied the effects of different management patterns on tomato（Lycopersicon esculentum
Mill.）growth，yield，quality and economic benefits．The results showed that the recommended drip irrigation
pattern could make the plant grow robustly，the stem diameters were separately increased by 14.71% and 2.24%
than that of the routine border irrigation and drop irrigation patterns．The recommended drip irrigation pattern could
obviously improve tomato quality，comparing with routine border and drip irrigation patterns，the VC content was
increased by 22.76% and 13.60%，soluble sugar content was increased by 7.29% and 5.10%，the sugar-acid ratio
was increased by 25.16% and 20.03%．The water and fertilizer saving effects were even more obvious，52.38%
and 25.00% water were saved，46.67% and 31.03% fertilizer were saved．The yield was the same for routine drip
irrigation pattern，and increased by 5.38% with the border irrigation pattern．As for the economic benefits，the
income increased by 28.87% and 9.98% than that of the routine border and drip irrigation patterns．
In order to screen the optimum cell pattern and nutrient solution concentration for cucumber
plug seedling growth under ebb and flow irrigation，this experiment took Cucumber（Cucumis sativus cv．
‘Zhongnong No.18’）as material，and adopted 2 patterns of cell（ regular and abnormal） and 3 nutrient solution
concentrations（×1，×0.5 and ×0.25）to conduct plug seedling growth under ebb and flow irrigation and to test
seedling mineral elements absorption，accumulation，and apparent morphological indicators，etc．The results
showed that along with the gradual increasing of nutrient solution concentration，the amount of mineral elements
absorption and accumulation were gradually increased，that of N，P，K were increased by 102.6%-125.1%．
The chlorophyll synthesis of leaf and seedling plant height，stem diameter，leaf area and fresh and dry weight
of stem and leaves were all increased with the nutrient solution concentration increasing．The effect of normal
plug seedling was better than that of the abnormal one．Thus，the seedling health index was taken as the major
reference index，and an optimal combination，i.e. regular cell pattern plus Hoagland nutrient solution at ×1
concentration level，was obtained．
Pot experiment was carried out to study the effect of phosphate-solublizing fertizer（PSF）on
pakchoi〔Brassica campestris L. ssp. chinensis（L.）Makino var. communis Tsen et Lee〕growth and quality，
and soil physicochemical properties．The results showed that after applying PSF，the total bacteria number
in soil was increased，among them the total number of phosphate-solubilizing bacteria was increased with the
increase of PSF applying amount．When the amount of PSF was 45 g·pot-1，the number of phosphate-solublizing
bacteria could reach 2.05×106 cfu·g-1．At the same time，the soil pH value decreased remarkably．With PSFapplication rate increase，the phosphate accumulation in pakchoi aboveground plant were increased remarkably
121.06%，226.43% and 302.09% more than the corresponding contrasts，respectively．The fresh and dry
weight of pakchoi were increased significantly，by 40.19%，52.71% and 33.56% more than the corresponding
contrasts，respectively．While the root shoot ratio reduced significantly．Among them，the root shoot ratio was
0.013，the lowest when PSF application rate was 45 g·pot-1．When the amount of PSF application was 45 g·pot-1，
the contents of VC，soluble sugar，soluble protein，and free amino acid were higher than that of the contrast
by 29.97%，39.94%，30.86%，17.36%，respectively．But the nitrate content in leaf blades was reduced to
21.83%．Therefore，the application of PSF formentated with bran could promote the utilization of insoluble
phosphorus in soil，and improve the yield and quality of pakchoic．
Taking 3 watermelon varieties‘ Huangxiaoyu’，‘Jinxin’and‘ Heimawangzi’ as material，this
experiment studied the effects of different amount Hydroxyapatite（ HAP） on cadmium accumulation，distribution
law and fruit quality of watermelon grown in moderate cadmium polluted soils，so as to verify the safety of
watermelon production. The results showed that applying 0.225 t·hm-2 HAP could significantly reduce the content
of available cadmium in soil and cadmium accumulation in different parts of watermelon. Applying of HAP had less
influence on watermelon fruit quality. The cadmium distribution law in watermelon plant was leaf ＞ root ＞ fruit.
There existed differences in cadmium absorption and accumulations between different watermelon varieties. Proper
watermelon varieties could still produce watermelon in line with the national food safety standard，even in the
moderate cadmium polluted soils.
To understand the variation of glucosinolates composition in backcrossing lines derived
from inter-varietal crosses in pakchoi，the content and composition of glucosinolates were analyzed by high
performance liquid chromatography（HPLC）for savoy〔Brassica campestris L. ssp. chinensis（L.）Makino
var. rosularis Tsen et Lee〕cv.‘Shanghaixiaobaye’，tai-tsai〔Brassica campestris L. ssp. chinensis（L.）
Makino var. tai-tsai Hort〕cv.‘Pingdutaicai’，and 2 lines selected from F2 populations of 4 times backcrossing of
（‘Shanghaixiaobaye’בPingdutaicai’）with‘Shanghaixiaobaye’as the recurrent parent．The results
showed that each of 4 kinds of aliphatic and indole glucosinolate were detected in the leaf and petiole of 4 tested
materials．The total contents of aliphatic glucosinolate，indole glucosinolate and total glucosinolate in leaves were
higher than petioles，and also different with 4 tested materials．The contents of health-beneficial compounds
2-phenylethyl glucosinolate（NAS）and glucobrassicin（GBC）were higher in leaves of‘6-1’than both its
parents‘Shanghaixiaobaye’and‘Pingdutaicai’，indicating that inter-varietal crosses could be used in breeding
new pakchoi cultivars with improved glucosinolate composition．
The experiment was conducted in the greenhouse of Hongyang Farm in Shanghai．Six
conventional cultivated pakchoi〔Brassica campestris L. ssp. chinensis（L.）Makino var. communist Tsen et
Lee〕cultivars were used to carry out comparative trial on clubroot resistance and to measure partial physiological
indicators between the susceptive and normal plants．The results showed that the disease indexes of‘Chaoyue
808’and‘Fusheng 218’were more than 30．They were susceptible．The disease indexes of‘Qingyang’and‘Ji
npinxialian’were 10-20．They were resistant．The disease index of‘Chaoyue 909’was less than 10．It showed
high resistance．The disease index of‘Jinpinlyuyoumei’was 0，it was immune．The leaf length，leaf width，
plant height，chlorophyll content，soluble protein content and Na+ content in root of the susceptible pakchoi plants
were lower than that of the normal plants among the 6 tested normal pakchoi cultivars．However，the contents of
soluble sugar，K+ content and K+/Na+ ratio in root were significantly higher than that of the normal plants．The
results of testing each physiological indicators showed that‘Jinpinlyuyoumei’could be used as major cultivar and
assisting breeding material in Shanghai area.
