Abstract: The wild-type Arabidopsis thaliana （Col） was used as a material, under the conditions of total artificial light source, the factors affecting the growth, temperature and sowing mode of A. thaliana were compared; the leaf growth rate, convulsion time and seed yield per plant of A. thaliana under different conditions were determined to measure the growth of A. thaliana. The results showed that the suitable light intensity of A. thaliana was 8 000~12 000 lx; the optimum light length was 9 h; the suitable temperature was 19 ℃; the direct seeding was more suitable for seedling vegetative growth..

Key words: Arabidopsis thaliana, leaf growth rate, yield per plant, total artificial illumination
