Abstract
To explore the effect of low temperature treatments on bud development and dormancy release of tulip bulbs.Apeldoorn bulbs were used as materials and stored at 2 ℃、5 ℃、9 ℃ and room temperatue(10～18 ℃)for 0 week,2 weeks,4 weeks,6 weeks,8 weeks,10 weeks,12 weeks and 14 weeks.The volume,water content,dry matter and reducing sugar content were measured.Under different temperature treatments,volume of bulbs,fresh weight,total water content and free water content decrease,while the relative content of dry matter increase with storage time.Along with flower bud differntiation,development and dormancy release,reducing sugar content presents regular change.It is better to preserve water and dry matter of bulbs by storing at 2 ℃ and 5 ℃,and benificial to prolong the storage life of tulip bulbs.
