    Author: Lv XL, Zhao Z, Wang HL.
    Journal: Zhong Yao Cai; 2010 Mar; 33(3):328-30. PubMed ID: 20681293.
    Abstract:
    OBJECTIVE: To study the influence of the Polygonum capitatum seed germination by different temperatures, cultivating methods and salt stresses, which can provide reference for seed germination inspection and field seeding. METHODS: Cultivating seeds in Petri dishes and count germination rate. RESULTS: The highest germination rate occurs at 15 degrees C; In salt stress condition, with the increase of the salt concentration seed germination rate declines and under the condition of low salt concentration germination rate shows no obvious difference with the controlling group; at the same temperature, germination rate is higher when cultivated with light than under dark, and seeds cultured in the filters have higher germination rate than those which cultured on the filter. CONCLUSION: Germination experiment should carry out at 15 degrees C, with light and between paper. Seeds germinate potential should calculate after the germination experiment progressing 20 d. When planting, salt concentration of the planting seedling field can not above 1 - 2 g/L, otherwise the germination will be affected.
