球果

Bract scale The structure found in large numbers in the female cone of gymnosperms, each bearing an ovuliferous scale in its axil.

在裸子植物雌球果中大量存在结构，每苞鳞都包含鳞。

The observed clinal variation in the frequency of serotinous cones may be described as a fairly regular decrease in all directions .

所观察到晚熟球果频率梯度变异可描述如下：向四周相当有规律地渐次减少。

After exogenous MJA treatment, the variation of the terpene volatiles in the conelet and cone were the same as the infested conelcets and cones, but the varying extents were not very high.

外源MJA处理后，与1年生和2年生受害球果挥发成分有变化，但变化程度要小得多。
