胚乳

Fruit juicy or dry, naked, scaly, hairy, bristly, or spiny, indehiscent or dehiscent, when juicy then pulp derived from often deliquescent funicles. Seeds usually numerous, often arillate or strophiolate; embryo curved or rarely straight; endosperm present or absent; cotyledons reduced or vestigial, rarely leaflike.

果多汁或干燥，裸露，有鳞片，有毛，具刚毛，或者具刺，不裂或开裂，种子通常多数，通常具假种皮或具种阜；胚弯曲或很少直；胚乳提出或无；子叶退化或者残留，很少叶状。

Seeds endotestal, with an abaxial chalazal knot and an adaxial raphe with 2 furrows, one on each side; embryo straight, small; endosperm oily, proteinaceous, copious, ruminate.

种子有内种皮，具有背面的合点结，以及正面的具有2槽的缝；胚直，小；胚乳油性，蛋白质状，丰富，嚼烂状。

Seeds linear, elongated, not beaked, apex comose; endosperm copious; cotyledons linear, flat, radicle superior.

结子线形，拉长，不发，先端；胚乳丰富线形，平的子叶，上位的胚根。

Seeds numerous, rarely solitary; seed coat crustaceous; endosperm copious; embryo small, straight.

种子多，很少单生；种皮壳质；胚乳丰富；胚小，直。

Seeds many; testa somewhat hard or crustaceous; endosperm copious, fleshy; embryo minute.

种子多数种皮稍坚硬或脆骨质；胚乳丰富，肉；胚小。

Seeds small, obovate, angular and wingless or planoconvex with a narrow marginal wing; testa crustaceous, shiny; embryo small, straight; cotyledons subrounded, clasping, embedded in copious fleshy endosperm.

种子小，倒卵形，具角和无翼的或平凸具一个狭窄的边缘的翅；种皮壳质，发亮；胚小，直；子叶近圆形，抱茎，嵌入大量肉质胚乳中。

Fruit drupaceous, or nearly a nutlet, often with headlike, wax-covered papillae; endocarp hard. Seeds nearly without endosperm; embryo straight; cotyledons fleshy, plano-convex.

果通常为核果，或者近小坚果，通常带有乳头状的蜡质凸起；内果皮硬种子近没有胚乳；胚直立；子叶肉质，平凸。

Seeds solitary, exalbuminous; testa membranous; cotyledons usually membranous, contortuplicate, rarely fleshy and planoconvex; radicle superior.

种子单生，无胚乳；种皮膜质；子叶通常膜质，卷折，很少肉质和平凸；胚根上位。

Seed horizontal, lenticular; testa leathery, lustrous; embryo annular; perisperm farinaceous.

种子水平，透镜状；种皮似皮革，有光泽；胚环状；外胚乳谷粉制。

Cotyledon and hypocotyl ' s rate and quamity are the most among these explams , and callus can be obtained in 10 days by cotyledon and hypocotyl . reversely it is difficult to indue callus with root , and the callus from root is lnde and easy to become browning . the calius obtained from leaf grows very slow and does not become browning uniill in 2 or 3 months

银杏的不同器官和组织都能够诱导出愈伤组织来，其中，子叶和胚轴10d左右全部愈伤化，诱导速度和诱导率均最高，根则很难诱导，愈伤组织很少，褐化很快；叶片诱导的愈伤组织，生长慢，褐化也慢，在培养基上保持两三个月而不褐化；胚乳的诱导时间也较长，需要30d左右。
