Abstract
The effects of methanol crude extracts of the seed coat and endosperm of Viburnum sargentii on the seed germination, seedling growth and antioxidant enzymes of Brassica chinensis were examined to understand the cause of seed dormancy of Viburnum sargentii. The results showed that the seed, especially the endosperm tissue of Viburnum sargentii, contained substances that strongly suppressed seed germination. With the concentration of crude extract of endosperm increasing, the MDA content increased constantly, while SOD activity was significantly inhibited. The research results indicated that inhibiting substances were existed both in the seed coats and endosperm for Viburnum sargentii seeds, It was concluded that Extract of the seed of Viburnum sargentii may influence the activity of protective enzymes and then affect the normal seedlings growth of Brassica chinensis.
