Chinese cabbage plays an important part in baskets in China, and so the quality of Chinese cabbage affect directly the vegetable market and people's life.
In order to advance the productivity of Chinese cabbage and the resistibility against severe circumstances, the liquid nitrogen(-196℃灶携行) was used to process 3 varieties of Chinese cabbage seeds in this research, testing their growth and cold resistance.

The results showed that seeds after processed by liquid nitrogen grew better than the comparison sample(without low-temperature processed);
The Hongkong Dark-leaf Pakchoi showed a fall in the death rate under cold condition after being processed;
No change happened to the(严隐和选,我不知道这是名字的一部分还是只是描述隐哗)Hongkong Milk Pakchoi at all;
The Short-petiole Yellow-leaf Sweet Pakchoi (水口白菜?我暂时给你翻成甜白菜了)showed a significantly reduced death rate;
This test provides strong theoretical evidence for both Chinese cabbage planting and resistible seeds producing.

Chinese cabbage dish in China, which occupies an important position in the basket, its production affects vegetable market supply and people's life. In order to improve the cabbage production and resistance, and experiments with liquid nitrogen (- 120 degrees Celsius) in three varieties of cabbage seeds in the process, growth and hardiness test. Results showed that the seed of being treatment group than cabbage growth, Hong Kong black leaves after being processed cabbage cabbage, in cold climates mortality decreases, Select NaiBaiCai no difference in Hong Kong, Short feet yellow shuikou cabbage mortality is reduced greatly. Test for the cultivation and breeding of cabbage art provides a strong theoretical basis.
