Abstract:
Radish (Raphanus sativus L.) is one of root vegetables，which can easily go through vernalization，results in bolting and flowering then lost the edible value when cultivated in spring.The effect of vernalization on germination，bolting，flowering，and physiological index were studied in this research using cherry radish as material.The results showed that vernalization treatment improved the seed vigor，promoted seeds to germinate.The longer vernalization time，the shorter time was needed for squaring，bolting and flowering.The soluble protein content，Chl content，POD and CAT activities were all increased before full flowering，and then decreased.At the stage of full flowering，the soluble protein content，POD and CAT activities under 20-day-old treatment were all higher than those under 5-day-old treatment.While MDA content increased from squaring stage to flowering stage.No differences exited on Chl and MDA contents between 20-day-old and 5-day-old treatment.The content of soluble sugar kept in a stable level in the process of flowering.The content of soluble sugar under 20-day-old treatment was higher than that under 5-day-old treatment at the squaring and bolting stage.ZT content decreased in the process of flowing.ZT content under 20-day-old treatment was higher than that under 5-day-old treatment.On the contrary，IAA content increased from the stage of bolting to decline，but there were no differences between 5-day-old treatment and 20-day-old treatment.The test conclusions were bolting and flowering of cherry radish was related with the changes of soluble protein content，POD activity，CAT activity and MDA content，the content of ZT and IAA.Furthermore，the length of vernalization time affected the above index to a certain extent.
