摘  要:
The test materials were chosen from whole seed tuber and pieces of seed, young small seed tuber (15—50g) , old big seed tuber (80—100g) and degenerated seed tuber (50—100g).During the germination and development stages, the changes in the amounts of dry matter, starch, protein and non-protein nitrogen, total nitrogen and phosphorus in tubers, and the activities of amylase, ascorhic acid, oxidase, and process of differentiation and growth of buds were examined systematically.The effect of different seed tubers on the plant development and yield of tuber was determined and analysed. Results showed that young small seed tuber was of great value as breeding stock.
