The primary structures, the genesis and the structure formed of the primary vascular system and the structural change in the process of cotyledonary senescence of the seedlings of antirrhinum majus and other angiosperms were studied. the progress had been aquired in the aspects as follows
本論文對金魚草等幾種被子植物幼苗的初生結構、幼苗發育早期初生維管系統的發生和建成后初生維管系統的結構以及子葉衰老過程中的結構變化作了較為全面的研究，在以下幾個方面取得了一定的進展： 1 -
In addition, there occurred difference in the structure of cotyledonary haustrum and other storages
此外在子葉吸器的結構和貯藏物等其它方面也存在差異。 -
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。 -
The first two reports of soybean transformation used two very different methods to transform soybean : hinchee et al ( 1988 ) used agrobacterium - mediated transformation of cotyledonary nodes while mccabe et al ( 1988 ) used particle bombardment of shoot meristems. soybean transformation reports following these initial papers have been limited and the transformation efficiency of soybean has remained low, the reason is that cells that are regeneration - competent must also be accessible and transformation - competent
目前應用於大豆遺傳轉化的方法主要有根癌農桿菌介導法，基因槍法，超聲波輔助農桿菌法，真空抽濾法，花山東師范大學碩士學位論文粉管導人法等，但其中獲得廣泛應用的只有根癌農桿菌介導法和基因槍法，但是這兩種方法在應用中也有一定的局限性。 -
( 1 ) plant regeneration system of cucumber contyledonary node was established. ( 1 ) the cotyledonary node was regarded as optimal explant by comparing the differentiation frequency of 3 kinds of explants ( cotyledon, cotyledonary node and hypocotyl ). ( 2 ) by discussing the effect of pgr ( naa and 6 - ba ) concentration and combination on differentiation frequency of adventitious buds, we concluded that the optimal shoot induction medium is ms basal medium with 1mg / l 6 - ba ( ph5. 8 )
（ 1 ）黃瓜子葉節植株再生建立東北農業大學理學碩士學位論文一通過對比三種外植體（于葉、子葉節、下胚軸）的分化率，得出最佳外植體類型為子葉節；通過探討pgr （ naa 、 6 ba ）濃度和配比對不定芽分化的影響，得出最佳芽誘導培養基為：卜1叭6 。 -
Soybean cotyledonary nodes were transformed with s gene of ibv via a. tumefaciens - med ated transformation. the highest transformation rate of 6. 7 % was detected in the present experiment
以子葉節為外植體，在抗性篩選培養基上大多白化死亡，有少數生長出芽，轉化頻率最高為6 . 7
