| 摘 要： | 蒙古扁桃的植株可分为长花丝植株、短花丝植株和中花丝植株。群落花期约50d,单花花期约8d,分为露粉、微开、盛开、凋谢4个时期。过氧化物法测定4个时期花粉均具活力,可保持30d左右,联苯胺-过氧化氢测定柱头可授性,花粉活力与柱头可授性重叠,长花丝植株为8d左右,而中花丝约为5d。蒙古扁桃花一般在9:00开始泌蜜,11:00分泌量达到高峰,之后产蜜量减少直至停止,日泌蜜和散粉集中在10:00～14:00。蒙古扁桃开花受环境的影响。

| Abstract: | Prunus mongolica can be devided into three kinds:long,middle and short-filament. The single florescenece lasts 8 d and last 50 d in large scale. The blooming time is divided into 4 periods:pink appearing,partly blooming,full blooming and withering,all of which have pollen viability and can last 30 d. Pollen viability and the life span of receptive stigmas overlapped,Long-filament more than 8d,but the middle-filament 5 d. The flower starts to secrete nectar usually at 9:00,and reaches the peak at 11:00,and then begins to reduce until stopping secreting nectar and spreading pollen take place between 10:00～14:00. In addition,the characters of flower blossom is influcened by the environment. |
