Vegetation Period — Chinese Cabbage

Brassica rapa L. subsp. chinensis (L.) Hanelt

The vegetation period of Chinese cabbage is defined as the number of days from the appearance of full seedlings until the leaf rosette reaches the marketable size of technical maturity.

In the reference 3 varieties crop Bok choy, where this is mentioned in the description.

For Chinese cabbage, this period typically ranges from 40 to 50 days for early-maturing varieties, while varieties with a period exceeding 60 days are significantly rarer. Measuring this interval is critical, as the crop is sensitive to day length and temperature regimes, which trigger the plant's transition to the reproductive phase.

High temperatures above 25 °C significantly accelerate plant development and provoke premature bolting. Understanding the duration of the vegetation period allows for planning sowing during periods with optimal day length, so that the active growth phase does not coincide with unfavorable environmental conditions.

Given the short cultivation cycle, the plant requires a stable level of moisture and nutrients throughout the entire development period. The inability to correct growth delays makes adherence to agricultural practices critical for obtaining high-quality marketable produce.
