lower portion of hypocotyl 中文意思是什麼
lower portion of hypocotyl
解釋
下胚軸下部-
During development of the seedling, the hypocotyl forms the lower portion of the stem from the radicle up to the cotyledons.
在幼苗發育期間,下胚軸從胚根到子葉的莖的下部形成。 -
According to the space - tim e maturation during the development of the vessel elements in primary vascular system : the vessel elememts of the cotyledons and the lower portion of cnz formed firstly, then downward hypocotyl - root zone, at length, the vessel elememts of the upper and middle portion of cnz and epicotyl - shoot region connected with each other, the result uphold the seedling partition model that divides seedling into cnz, hypocotyl - root region and epicotyl - shoot region
根據金魚草幼苗初生維管系統導管分子發育的時空性,即子葉和子葉節區下部導管分子先形成,然後向下形成下胚軸-根區的導管分子,最後子葉節區中、上部與上胚軸-苗區的導管分子再發生連接,據此支持將幼苗分為子葉節區、下胚軸-根區和上胚軸-苗區的幼苗分區模型。 -
The results showed that the vessel element did n ' t differentiate after the seeds had imbibied for 6 hours ; 6 hours after seeds germination, two loci ? ne below the middle portion of the cotyledon and the other in the lower portion of cotyledon - node zone ( cnz ) initiated the differentiation of vessel element simultaneously, then elongated towards the cotyledonary apex and hypocotyl - root region respectively ; eventually the two promoter loci began to interconnect through vessel elements
結果表明:種子吸漲6h ,未有導管分子的分化;種子萌發后6小時期間,自子葉中部偏下方和子葉節區下部的兩個位點同時啟動導管分子的分化,並分別向子葉葉尖和下胚軸-根的方向延伸;爾后,在發生兩個啟動位點之間發生導管分子的連接。
