Heat Tolerance in White Cabbage

Brassica oleracea L. (White Cabbage Group)

The ability of cabbage plants to maintain physiological processes and form a high-quality yield when exposed to high temperatures. This trait is critical for preventing growth inhibition, leaf yellowing, and degradation of marketable head characteristics during the summer period.

In the reference 4 varieties crop White cabbage, where this is mentioned in the description.

Heat tolerance in cabbage is determined through a complex of morphophysiological indicators, including cell membrane stability, assessed by electrolyte leakage levels, and the maintenance of photosynthetic activity under heat stress. Important indicators of adaptation include biochemical markers such as proline accumulation and increased activity of antioxidant enzymes, including superoxide dismutase, catalase, and peroxidase.

At the molecular level, breeding relies on the expression of specific genes, such as BoHSP70, BoSCL13, and BoDPB3-1, which serve as markers for heat resistance. Heat-tolerant hybrids demonstrate the ability to form dense heads under unfavorable thermal conditions, which also correlates positively with post-harvest storage quality in late-maturing varieties.
