Abstract:
Taking Magnolia sieboldii cultivated in Shenyang area as material，the phenophase，morphological changes of buds，flowering habits and branches，leaves and fruits growth dynamics and other biological characteristics were detailed.The results showed that M.sieboldii buds began to sprout in early April，growth period about 150 days，vigorous growth period lasted about 50 days from early May to mid-June；growth amounts of branches，leaves and fruits was the largest in May to June，new shoots growth during this period accounted for 81% of the new shoots total growth (18.3 cm) that year; M.sieboldii had a ‘second flowering’ phenomenon,the first flowering (the main flowering) in late May to mid-June，lasted about 20～30 days，the second flowering in late July to early August，small number of flowers，short duration；the fruits from growth to mature need about 90 days，maturity in September to October.
