Zahra Salimi

During her studies, Zahra Salimi has investigated the possibility of using new technologies for rapid and non-destructive evaluation of seed quality parameters. Next step in her project was to advance the seed performance during different phenological stages. Various influential factors in improving the seed performance were tested on sugar beet as the model plant. Optimized seed enhancement treatments were applied on seeds of different beets (beetroot, red beet, salad beet) to improve germination, which could lead to faster flowering and shorter seed production cycle. Moreover, selected treatments were studied on seeds with different levels of maturity.

The new research findings contribute to the understanding of the importance of knowing your seeds properly before starting to treat them. Assessing the quality of seeds, before enhancement treatments is the crucial step. In addition, different experimental parameters need to be adjusted for each batch of seeds. Eventually, seeds of distinct maturity should be treated due to the developmental level of their structure. When enhancement treatments were adjusted to the initial seed quality, the time to germination and flowering was reduced.

The PhD degree was completed at the Department of Agroecology, Science and Technology, Aarhus University, Denmark.
