Blackheart and senescent sweetening: Two serious physiological issues with potato tubers during storage

In the latest issue of AHDB Potatoes’ regular Storage Bulletin, it is noted that potato tubers are living organisms that go through a number of physiological processes
during storage, such as respiration and dormancy. These processes are affected by a
variety of factors, which determine the quality of your potatoes and their resulting value
in your market of choice. It is therefore crucial to regularly sample and assess the quality
of your potatoes during storage, to identify and address any problems before it is too late.
The authors of the Storage Bulletin highlight a couple of known examples in this month’s bulletin: blackheart and senescent sweetening.

Tubers affected by blackheart are particularly difficult to detect because they appear perfectly healthy externally. Inside, however, symptoms typically occur at the centre of the tuber and include necrotic tissue, often with some cavities. This can have significant financial implications for suppliers
and retailers in the fresh potato industry. A lot of storage for processing is about avoiding low temperature sweetening but, at this time of year, growers need to think about senescent sweetening. It is critical to detect it, because it is irreversible. Read the full May Bulletin
