Study on the Change and Judgment of Tobacco Seed Maturity

Study and judgment of tobacco seed maturity, and then chose the optimum harvest time have important significance to some agriculture production problems, such as: high quality germplasm resource conservation, utilization, development and improve seed quality and production. This study research the changes during tobacco seed maturity, including morphological changes (seed color), physiological changes within the seeds (water content, germination) and chlorophyll fluorescence (CF) in seed coat changes; and presented the application of these metric to judge the tobacco seed maturity; further studies in this fields and issues that be occurred are also addressed in the paper.
