Abstract：Chinese cabbage〔Brassica campestris L. ssp．pekinensis（Lour.）Olsson〕shows leaf color transition during the period from vernalization to bolting. After the change it will bud and then bolting，flowering．This phenomenon is particularly prominent in early-bolting species．In present study，Chinese cabbage cultivars of late-bolting and early-bolting were used to investigate the physiological changes during leaf color transition in the bolting process．The results revealed that there were some correlations between leaf color transition and the hormones，pigment content and protein composition．The content of chlorophyll（a/b），IAA and GA3 reached their peak in bolting process，the stem initiates elongation growth after leaf color is changed．The changes of leaf color are physiological signal in Chinese cabbage bolting．
