rachis

基本解釋

That is interesting because the rachis seems to aid in flight.
這就很有趣了，因?yàn)橛疠S似乎有助于飛行。
Raceme rachis and pedicels pubescent or puberulent ; bract and bracteole usually borne on distal 1/2 of pedicel.
總狀花序軸和花梗具短柔毛或微柔毛；苞片和小苞片通常生于花梗上部的1/2。
Pedicels of spikelet pair equal, as long as rachis internode; upper glume with 0. 5–1 mm mucro.
小穗對(duì)的花梗等于，倍于軸節(jié)間；上面穎片具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.
用常規(guī)石蠟切片法和顯微觀測技術(shù)，對(duì)開花后28天的901、恢復(fù)系、不育系和陜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)維管束進(jìn)行顯微觀測。
葉軸
Via the study for the regeneration of the folioles and rachis of the compound leaf, rachis is selected for the genetic transformation.
通過對(duì)刺槐復(fù)葉中小葉和葉軸兩部分的再生試驗(yàn)，確定刺槐的葉軸作為本試驗(yàn)進(jìn)行遺傳轉(zhuǎn)化的受體材料。
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.適合花序軸誘導(dǎo)試管球的最佳培養(yǎng)基為MS+BA10mg/L+NAA5mg/L+蔗糖30g/L,有效誘導(dǎo)率達(dá)到171.3%。
