摘要
５℃±２℃和７９．７ｋＰａ的低压环境可有效地保存杏花粉１２个月。新鲜花粉在１６℃或－２０℃条件下进行低压（７９．７ｋＰａ）预处理３０ｍｉｎ后，投入ＬＮ２保存，两种温度对花粉生活力影响差异很小，这种花粉在２６℃水化处理后，即可恢复活力，但低压条件下（２４．
Apricot ( Prunus armeniaca L.) pollen could be stored effectively for one year under hypobaric atmosphere (79.7 kPa) at 5℃±2℃. Fresh pollen was pretreated in vaccum condition (79.7 kPa) at 16℃ or -20℃ for 30 min., and then stored in liquid nitrogen (LN 2).The germination by different temperature pretreatments had similar effects.Cryopreservative pollen had to be rehydrated for recovery of germination at 26℃. There was no significant difference in pollon vitality of apricots between the hypobaric atmosphere (24.8 kPa) and the normal barometric pressure (101.3 kPa) stored in LN 2.
