The present work was de-signed to study systematically the changes of anther and pollen during themannitol pretreatment period on physiology and biochemistry;and then the ef-fects of mannnitol pretreatment on androgenesis and anther culture were stu-died.The donor plants used in this experiment grow in the field.

The results were as follows. Pollen pretreated with 0-4 ℃ low temperature could abort the inducing stage that androgenesis needed, but most pretreated pollen (93.6%) still kept vigor when abortion occurred, and the frequency of callus differentiation reached 1.33%. On the contrary, most unpretreated pollen degenerated and died.

结果表明：0~4℃的低温预处理花药1d，花粉可以完成其进行雄核发育所需要的诱导过程，而且绝大部分花粉(93.6%)仍然保持存活，花药分化率达到1.33%；而未经预处理的花药在诱导过程完成时，大多数退化死亡。
