      abstract     = {Vegetable product quality is an important consideration for
                      consumers. Long-term root cooling could improve certain food
                      quality of horticultural crops, but often comes at the
                      expense of reduced shoot biomass or yield. Since few studies
                      have investigated how fast Chinese broccoli (Brassica
                      oleracea var. alboglabra Bailey) responds to changes of root
                      temperature, we shortened the duration of the root cooling
                      treatment to one week before harvest to make the production
                      system more effective. The aim of this study was to improve
                      the food quality of Chinese broccoli without causing
                      deleterious effects on plant growth and yield. The seedlings
                      were cultivated hydroponically at two root temperatures (10
                      and 20 °C) during the last week prior to harvest in summer
                      2018 (Exp-1) and autumn 2019 (Exp-2). Plant growth, yield,
                      physiological variables, soluble sugars, total chlorophyll,
                      glucosinolates and mineral elements concentration were
                      examined. The results showed that the yield reduction was
                      alleviated compared to results over the long-term.
                      Specifically, yield was not affected by root cooling in
                      Exp-1 and reduced by $18.9\%$ in Exp-2 compared to 20 °C.
                      Glucose and fructose concentrations of the leaves were
                      increased when the root temperature was 10 °C in both
                      experiments with a more pronounced impact in Exp-2. In
                      addition, root cooling produced a significant accumulation
                      of individual glucosinolates, such as progoitrin,
                      gluconapin, 4-methoxyglucobrassicin and
                      4-hydroxyglucobrassicin, in the stems of Exp-1 and the
                      leaves of Exp-2. Minerals, such as N, showed reductions in
                      the shoot, but accumulation in the root. Therefore, compared
                      to long-term root cooling, short-term (one week) reduction
                      of the root temperature is more economical and could help
                      improve certain quality characteristics of Chinese broccoli
                      with less or even no yield reduction.},
