芽鳞

本属的进化趋势为冬芽芽鳞由数枚减少到2枚，花序由总状圆锥花序→复伞房花序→伞房花序→伞形花序。

This genus ' evolutionary direction : the number of winter bud scale is from many to two , inflorescence : compound raceme → compound corymb → corymb → umbel .

该螨一年多代，主要以成螨在芽鳞下越冬。

EPP mainly overwinters as adults beneath bud scales .

形态特徵：常绿乔木，高可达5米，芽鳞密被白灰色丝光质短伏毛。

Description : Evergreen trees , up to 5 m high ; bud-scales densely covered with grayish silky short hairs .

结果表明：萌发早晚与品种的芽鳞厚度、芽鳞表皮厚度成高度正相关；

The result showed that : ( 1 ) The significant positive correlation exists in the sprouted period and bud scale , also it 's epidermic thickness ;

以上几个品种叶片发育的规律为：芽下第一叶、鳞叶表皮毛数量较多，芽下第二叶、芽下第三叶、芽下第四叶、鱼叶表皮毛数量较少。

Leaf growth of varieties was as follows : The first leaf , scale leaf had more trichomes , the second leaf , the third leaf , the fourth leaf , fish leaf had fewer trichomes .

芽下第一叶、鳞叶气孔器发育不完全，芽下第二叶气孔器发育趋向成熟、芽下第三叶、芽下第四叶、鱼叶气孔器发育成熟。

Stomata of the first leaf buds , scales leaf were not fully developed , stomata of the second leaf tent to mature . Stomata of the third leaf , the fourth leaf , fish leaf was mature .

冬芽能否萌发取决于芽鳞的阻碍作用力与叶原基、生长点或花原基萌发力的平衡状态；

The sprouting capacity of the winter buds was determined by the force balance between the oppressing force of the bud scale and the sprouting forces from the phyllome , growth point or flower primordia .
