| Popis: | Assessment methods of physiological age of potato seed tuber (Solanum tuberosum L.). The study of potato tuber ageing possesses both fundamental and applied interests. Because of potential economical impacts, numerous attempts have been made to develop reliable biophysical, physiological or biochemical markers of physiological age of seed tubers intended for vegetative multiplication. At the present time, biophysical markers do not meet this objective, the obtained results being contradictory or not very transposable. Some physiological markers seem well-suited but they are not predictive. The biochemical studies often focus on potato tuber developmental process or are undertaken without accurate physiological reference frame. After defining the main concepts, this study synthesizes and critically evaluates the different methods used to assess physiological age. An integrated research strategy based on existing data is finally proposed to study potato tuber ageing. |
