Cultivation
Brassica oleracea L. (Cauliflower Group)
Growing cauliflower in the open field requires strict adherence to a temperature range of 15–22 °C and protection of the heads from sunlight to prevent deformation and discoloration.
In the reference 138 varieties crop Cauliflower, where this is mentioned in the description.
Cauliflower in the open field shows high sensitivity to temperature fluctuations. The optimal development range is 15–22 °C, with deviations from these values being critical: high temperatures lead to loose and deformed heads, while low temperatures result in the 'vernalization' of seedlings and the formation of small inflorescences. The crop is vulnerable to frost: seedlings are damaged at -3 °C, and formed inflorescences at -2 °C.
To preserve the marketability of the heads, they are typically shaded by the plant's own leaves, which prevents yellowing and browning of the inflorescences under direct sunlight. Managing crop development requires control of nitrogen nutrition, which is limited during the inflorescence formation period, as well as maintaining an optimal soil water-air balance, as excessive moisture negatively affects the root system.
