Freezing tolerance — China aster
Callistephus chinensis (L.) Nees
China aster is a cold-hardy crop capable of withstanding short-term frosts down to –3…–4 °C. Low-temperature seed storage is used as an effective method for maintaining seed viability.
In the reference 23 varieties crop China aster, where this is mentioned in the description.
Seedlings and mature plants of China aster are adapted to open-field conditions with potential temperature drops. The crop is characterized by biological resistance to short-term frosts, maintaining viability when exposed to temperatures as low as –3…–4 °C.
In breeding and seed production practice, low-temperature storage technologies are used to preserve the quality of seed material. Freezing conditions for seeds allow for a significant slowdown of degradation processes and ensure the long-term maintenance of high germination rates.
