Abstract:
Experiments over four years measured the extension of the growing point and head growth of the Chinese cabbage cvs Jade Pagoda and Kasumi. In the first three years, three transplantings of plants raised at different temperatures provided data from weekly crop samples to develop simple models of increased growing point height and head weight. Effects on the former established during raising were largely maintained after transplanting. It is suggested that head development and growing point extension differ in their dependency on meteorological variables. Increased field temperature achieves a marketable head weight before the growing point becomes unacceptably high, but this is less likely with increased solar radiation. The models effectively describe independent data from the fourth year.
