胚柄 的英文怎麼說
中文拼音 [pēibǐng]
胚柄
英文
blastostyle-
When ovule orientation is orthotropous the chalaza corresponds to the point where the funicle is attached but in anatropous and campylotropous ovules the chalaza is some distance from the funicle
當胚珠的方向是直生胚珠時,合點和珠柄連成一條直線,當胚珠是倒生胚珠或彎生胚珠時,合點和珠柄之間有一定的距離。The suspensor is thought to function as a channel for the conduction of food materials.
胚柄被認為是作為運輸營養物質的通道。Funicle ( funiculus ) the stalk attaching the ovule ( later the seed ) to the placenta in angiosperm ovaries. nutrients pass through the funicle to the ovule and seed
珠柄:被子植物子房中連接胚珠(之後的種子)和胎座的柄。營養物質通過珠柄傳遞到胚珠和種子。The scientist has made a pointed comparison between suspensors of plant embryos and mammalian trophoblasts.
這位科學家把植物胚的胚柄與哺乳動物的滋養層做了直接的比較。Early division phase embryos may use metabolites provided by the suspensor, persistent and degenerating synergids.
早期分裂時期的胚可以利用胚柄,宿存和退化中的助細胞所提供的代謝物。These plants develop elaborate haustorial structures from the suspensor.
這些植物從胚柄中發育出精緻的吸器組織。Proembryo a young plant after fertilization but before differentiation into embryo and suspensor tissue
原胚:從受精卵分裂形成2細胞胚開始至胚芽和胚柄等器官分化之前的胚。So, the rank of inducing callus from easy to hard is cotyledon, hypocotyls, stem, leafstalk, radicel, endosperm, leaf and root. 3
誘導的難易分別為:根段、葉片、胚乳、胚根、葉柄、莖段、胚軸、子葉。It also serves as a passage for nutrients to pass from the parent tissue to the embryo
另一方面,胚柄還是營養物質從母體組織向胚胎運送的通道。It showed that the induction efficiency of the resistant calli were the same among all explants of different age, but the embryos on the calli from explants of 7 days appeared earlier than those from explants 11 and 30 days. in order to compare the resistant calli induction efficiency, petioles and hypocotyls were excised from 30days aseptic seedlings to transform with pbinctbs under the same condition. the resistant calli induction efficiency of petioles was higher than those of hypocotyls. a more detailed analysis of the different types of explants showed that the number of pcr positive plants induced from petioles was higher than that from hypocotyls
在相同條件下的轉化實驗中,發現不同苗齡的外植體的抗性愈傷的誘導頻率基本相同:還進一步研究了胡蘿卜同一苗齡不同部位的抗性愈傷形成率,同時用3od苗齡(照光3周)的葉柄和下胚軸做轉化實驗,發現葉柄的抗性愈傷形成率高於下胚軸的抗性愈傷形成率,進一步的實驗發現,由葉柄誘導的苗子的陽性率高於由下胚軸誘導的苗子的陽性率,此結果和pawlicki的結論是一致的。分享友人
