接穗和砧木的小孢子叶球的过氧化物酶同工酶都出现干扰酶带，尤其对砧木影响较大，同时还影响其顺序表达；

The peroxidase isozyme of microstrobilus in scion and stock appear interfere isozymes , especially affect on the stock ; and influence on their genes sequential expression ;

结果表明：其小孢子叶球5月中下旬开始萌动，小孢子囊着生在小孢子叶远轴面，且3-5小孢子囊以辐射状排列方式聚生成聚合囊。

This species tends to initiate the male cones in middle or late May . The microsporophylls bear their microsporangia on the abaxial surface , and 3-5 microsporangia seem to be arranged radially into a sorus with a stalk .

研究认为，小孢子叶球长度、始花期、花药长度及花粉粒大小除受遗传因素影响外，年份间树体营养的积累、消耗状况对其也有重要影响。

The result showed that aside from genetic factors the nutritional level of the plant in different years had important influence on the lengths of the microstrobilus and anther , the pollen grain size and the beginning of flowering .
