1 The experimental vegetables were winter pakchoi and summer pakchoi.

2 The experiment on comparison of 9 pakchoi varieties was carried out in summer.

3 Inheritance of salinity tolerance in Pakchoi fitted to the "additive-dominant" model.

4 Method for the determination of pyrimethanil residue in pakchoi , rice, strawberry, grape, and tomato by means of SPE-GC was developed, respectively.

5 Effects of dredged from the Grand Canal ( Hangzhou Section ) on pakchoi were studied using pot experiments.

6 Results were as follows: (1) The shoot dry weight and the amount of Zn accumulation can reflect better the differences of capacity to acquire zinc from soils among six pakchoi cultivars.

7 A hydroponic experiment was carried out to study effects of higher ammonium rate on yield and quality of pakchoi growing under low light intensity.

8 Study on the dynamic accumulation rule that cadmium and copper accumulate in Pakchoi (Brassica chinensis L) different portions by simulating pollution.

9 Influence of the fertilizer recommending amount generated from Precision Fertilizer Recommendation System of Vegetable(PFRSV) on pakchoi and soil characteristic was studied.

10 By replacing nutrition solution with clear water during the later stage of growth,[] the nitrate content of pakchoi was significantly reduced.

11 Usinging dicyandiamide (DCD) as reference material, field experiment was conducted to study the effect of N-lignin (ZAOL) on contents of nitrate and vitamin C in pakchoi.

12 The yield, vitamin C and nitrate contents in the edible parts of pakchoi were also increased, and hence the nutritional quality was improved.

13 Effects of complexes of alga polysaccharide with rare earth on degradation of organophosphorus pesticides residues in pakchoi, cabbage and celery were investigated.

14 Study on the dynamic accumulation rule that cadmium and copper accumulate in Pakchoi different portions by simulating pollution.

15 An analytical method for residue and degradation dynamics of carbaryl in pakchoi and vegetable soil were studied by HPLC.

16 A field experiment was conducted to study the effects of organic fertilizer, DCD and the compound agents of oxalate, glycine and KCl on the yield and quality of pakchoi .

17 At this moment, we can supply all kinds of seeds, such as pakchoi , cabbage, cauliflower, tomato, cucumber, eggplant, lettuce, pumpkin, water melon, sweet melon, beans.

18 However , the spraying of BDM inhibited the growth of pakchoi markedly.

19 Cu and Cr had antagonistic effects on seeds germination and root elongation of Pakchoi Meanwhile, the antagonism of Cu against Cr was in response to the concentration of Cu.

20 The path analysis suggested that head width, blade width, leaf numbers, and petiole width were the main factors affecting on plant weights of pakchoi .
