珠鳞
Bract scale The structure found in large numbers in the female cone of gymnosperms, each bearing an ovuliferous scale in its axil.
苞鳞:在裸子植物的雌球果中大量存在的结构,每个苞鳞都包含一个珠鳞。
At the end of February, the bract attained approximately their full size, and a pair of anatropous ovules were initiated on the adaxial surface at the base of the fertile ovuliferous scale.
2月底,苞片体积不再发生变化,珠鳞膨大端的基部的近轴面分化出2个倒生胚珠。
