uppermost internode

基本解釋

GA_3 had promoting effect to the elongation ofpanicles extension, uppermost internode, the second internode. and the length of stem.
GA_3對(duì)穗頸伸出長(zhǎng)度、第一節(jié)間長(zhǎng)度、第二節(jié)間長(zhǎng)度和莖長(zhǎng)有明顯的促進(jìn)作用，表現(xiàn)爲(wèi)隨著濃度的增加的趨勢(shì)。
It is evident that the uppermost internode shortening of Peiai64S is due to the decrease of cell number and the shortening of cell length, and the effect of later is more obvious.
培矮64S穗頸節(jié)間縮短是由細(xì)胞數(shù)目減少和細(xì)胞長(zhǎng)度縮短雙重作用所致，其中後者作用更顯著。

But after the abortion, the development of ZS97A pollen was impaired and the elongation rate decreased, leading to panicle enclosure by shortening the uppermost internode (UI) length.
而伴隨著花粉發(fā)育受阻至花粉敗育之後，ZS97A的節(jié)間伸長(zhǎng)速率下降，最終導(dǎo)致倒一節(jié)間縮短而引起包穗。
