Effects of growing temperatures (15 deg C, 30 deg C, 25 deg C and 30 deg C) on growth and development of Chinese kale (Brassica oleracea L. var. alboglabra L.H. Bailey) cultivars with yellow petals were investigated. 'Chugoku-kairan (Y)' cultivar formed flower buds when exposing under 115 deg C for six weeks, whereas this response on flower bud development was not seen in 'Kibana-kakurin' even after ten weeks of exposure under the same conditions. The stem length of both cultivars at 25 deg C was longer than that at 20 deg C and 30 deg C. Stem diameter of 'Chugoku-kairan (Y)' and 'Kibana-kakurin' at ten weeks of exposure had a tendency to increase at higher temperature. Unfolded leaf number at ten weeks of exposure had a tendency to increase at higher temperature.
