The results as followes: when bud germination ,the earlist one is Sambucus williamsii Hance and the latest one is Lonicera caerulea L. var. enulis Turcz et Herd;Sambucus williamsii Hance and Lonicera caerulea L. var. enulis Turcz et Herd were flowering earlier, but the latest one was Lonicera tatarinowii. When the fruit were ripe, Lonicera caerulea L. var. enulis Turcz et Herd was the earlist one and Viburnum mongolicum(Pall.)Rehd.was the latest one. The longest flowering period was Lonicera chrysantha Turcz., which reached 15 days, the shortest ones were Sambucus williamsii Hance and Lonicera caerulea L. var. enulis Turcz et Herd,which only were 9 days. Fruit development period can be from 29 days to 94 days, wich were Lonicera tatarinowii and Lonicera chrysantha Turcz..
