Abstract: 5 heading Chinese cabbage(Brassica campestris L.ssp.pekinensis) and 5 non-heading Chinese cabbage (Brassica campest ri s L.ssp.chinensis) were studied on bolting ability and flowerings tage through 5 di fferent veneration controls 0, 15, 20, 25, 30 days.Results showed, for Chinese cabbage materials with st rongest and stronger bolting ability,the bolting time is nearly 20 days, for example, B, D and E materials.The weaker bolting materials, for example A and C,the bol t ing time is nearly 15 days.For non-heading Chinese cabbage the bolting t ime is nearly 15 days.In this paper 5non-heading Chinese cabbage except that J material had stronger bol ting abi li ty, others were nearly the same in bol t ing abili ty.They could not be dis t inguished.The reason may be related to the light affecting bolting ability.Therefore, light is the main reason for bolting and flowering for non-heading Chinese cabbage when the bol t ing time is sufficient tobolt.
