Abstract:

 Germination characteristics about Menghai Daye tea (Camellia sinensis var. assamica cv. Menghai Dayecha) were explored in this paper. Results showed that hard seed coat influenced germination. When water content was high, getting rid of seed coat promoted germination percentage, but keeping seed coat became an advantage for seed germination when water content decreased. Optimum germination temperature was 30℃, bellow 15℃ was harmful temperature. The effect of 20/30℃ alternating temperature treatment on raising germination percentage was not notable. Effects of different soil types on germination percentage of Menghai Daye tea seeds were not notable too. Soil type was not a crucial factor during seed germination period of Menghai Daye tea.

Key words:  Daye tea seeds, Dehydration, Temperature, Seed coat, Soil type
