Abstract:
‘Carmine No1’radish seedlings were used as materials,6 different diurnal temperature treatments,including 5 ℃/5 ℃ (day/night),10 ℃/5 ℃,15 ℃/5 ℃,20 ℃/5 ℃,15 ℃/10 ℃,and 15 ℃/15 ℃ were set in an artificial illumination incubator to study the optimum conditions of radish vernalization and bolting,in order to provide reference for preventing the radish from the premature bolting and for propagation.The results showed that the different temperature between day and night and low temperature could not only promote radish bolting,budding,flowering and flower bud differentiation,but also promote the axillary buds forming to branches,and the longer the treatment time,the more obvious role.The day/night treatment at 10 ℃/5 ℃for 18 days was the most optimal condition for radish bolting and flower bud differentiation.Based on the effects of different day/night temperature treatments on plant height,stem diameter,the largest leaf length and width,low temperature obviously inhibited plant vegetative growth.The longer vernalization time,the easier forming branches for axillary buds.However,while flowering and podding,the quality of the flowers was significantly reduced,and the flowers were relatively short,with moreobvious inhibitory effect on radish stem diameter,as well the largest leaf length and width.The results could provide the theoritical basis for controlling the radish bolting and flowering and thus to improve the radish yield and quality.
