    Strains Comn 1 and No.1800 of Staphylococcus aureus have been first compared during serological tests for detecting tomato viruses by virobacterial agglutination test (VBA). The results showed that the strain No. 1800’s sensitivities were 2~ 10 times higher than strain Comn 1’s. The former enabled the detection of ToMV,CMV and PVX viruses at a concentration of 3.4 ~ 13.0 ng / mL and the maximum leaf sap dilution of 1/ 1000 ~1/ 100000, which were almost equal to them by PAS-ELISA. ...

    The toxicity of several organophosphorus insecticides chlorpyrifos,dimethoate,malathion and dichlorvos to the larvae and female adult of Liriomyza sativae was determined. The adult eating and egg laying repellent in choice and no choice assays were also investigated. The results indicated that the 1st,2nd and 3rd instar larvae and female adult of leafminer were very sensitive to chlorpyrifos,the LC 50 of the 1st,2nd and 3rd instar larvae was 0.0682,0.1216 and 0.1423 g/L respectively. For female a...

    The experiment was conducted using different of complex media mixed with local cheap materials in different ratio,cottonseed shell,furfural residue,vermiculite,pig manure and coal cinder,in order to study effects of the complex media on celery plug seedlings. The results indicated that the growth and nutrient uptake of celery seedlings were evidently promoted and dry matter accumulation of seedlings was increased in the treatment using complex media with compared with control (peat). Two kind of complex med...

    The prematurity and yield of six varieties of L. cylindrica were compared in fields. The results showed that ‘Jingmenzhong’ and ‘Hangzhou Rousigua’ with low node position of the 1st female flower,high early yield and total yield,were suitable for purpose of prematurity breeding,so was ‘Baiyushang’ with higher early yield and medium total yield. ‘Changsigua’ with strong growth and high total yield was useful for breeding also. But ‘Xiaoshaozhong’ ‘Dashaozhong’ and ‘Bangchuigua’ could not be directly used...

    Jinlu No. 4’ is a new open field hybrid bred from F15 and Q24. It is early maturing, high resistant to downy mildew,powdery mildew and Fusarium wilt. It needs only 60 days from sowing to the first harvest,its early yield is about 10.5 t/ ha, and total yield reachs 82.5 t/ ha, which is 15% ~ 20% higher than that of ‘Jinchun No. 4’. It is tolerance to high temperature and can grow well under 34 ~ 36℃ day temperature. The fruit shap is straight bar and average weight per fru...

    Xinfan No. 5’is a F 1 hybrid crossing ‘Zhongshu No. 6’ and line ‘0307’ with nonripening gene. The plant habit is indeterminate. The fruit is dark red and round. Average fruit weighted 140~160g. Thick skin and meat make the variety storable and resistant to cracking. When the fruits were stored for 70~90 day in autumn under room conditions. Seventy percent of fruits remained good.

    Qifan No. 6’,a new pink determinate tomato variety,was bred through composite hybridyzation. It is virus resistant and adaptable for condensed planting. The variety gave 140g to 160 g per fruit and 95 days from sowing to first harvest. Its harvest period duration concentrates only in 10 days and its early yield occupies 85% of total yields.
