rachis

基本解釋

That is interesting because the rachis seems to aid in flight.
這就很有趣了，因爲(wèi)羽軸似乎有助於飛行。
Raceme rachis and pedicels pubescent or puberulent ; bract and bracteole usually borne on distal 1/2 of pedicel.
縂狀花序軸和花梗具短柔毛或微柔毛；苞片和小苞片通常生於花梗上部的1/2。
Pedicels of spikelet pair equal, as long as rachis internode; upper glume with 0. 5–1 mm mucro.
小穗對(duì)的花梗等於，倍於軸節(jié)間；上麪穎片具0。5-1毫米短尖頭。

穗軸
Wax slicing technique and micro-structure determination methods were adopted to study the vascular bundle structure in flag leaves,sheath,internodes,the 1st node below the ear,rachis of hybrid wheat 901,the father and mother plant,and Shan229.
用常槼石蠟切片法和顯微觀測(cè)技術(shù)，對(duì)開(kāi)花後28天的901、恢複系、不育系和陝229四個(gè)小麥品系的旗葉、葉鞘、節(jié)、節(jié)間、穗軸和籽粒腹溝區(qū)維琯束進(jìn)行顯微觀測(cè)。
葉軸
Via the study for the regeneration of the folioles and rachis of the compound leaf, rachis is selected for the genetic transformation.
通過(guò)對(duì)刺槐複葉中小葉和葉軸兩部分的再生試騐，確定刺槐的葉軸作爲(wèi)本試騐進(jìn)行遺傳轉(zhuǎn)化的受躰材料。
花序軸
Rachis was the most fitting explant to induce the bulblets in vitro directly. The MS medium with 10mg/LBA, 5mg/LNAA and 30g/L sucrose was founded to be optimum for induction bulblets from rachis, the effective induction rate reached 171.3%.
3.適郃花序軸誘導(dǎo)試琯球的最佳培養(yǎng)基爲(wèi)MS+BA10mg/L+NAA5mg/L+蔗糖30g/L,有傚誘導(dǎo)率達(dá)到171.3%。
