| 摘 要： | 为了探讨AgNO3在离体培养物形态发生中的作用,以金水梨组培苗为外植体,研究了不同浓度AgNO3对梨叶片再生不定芽过程中内源多胺含量的影响。结果表明,多胺含量会随着外植体细胞分裂分化迅速增加,其中腐胺含量在培养5d时形成高峰,精胺在20d时出现峰值,而亚精胺在培养过程中2次出现峰值。经AgNO3处理后叶片内源多胺含量与对照相比明显增多,其中以0.1mg/LAgNO3处理效果最明显。

| Abstract: | Effects of different AgNO3 concentrations on the content of endogenous polyamine in in vitro leaves of Pyrus brestchneideri Rehd.cv.Jinshui was studied in order to understand the effect of AgNO3 in the process of in vitro morphologe-nesis.The results indicated that the content of endogenous polyamine would be enriched with cell division and differentiation.The content of putrescine(Put) and spermine(Spm) formed pinnacles on 5th day and 20th day respectively,while the content of spermindine(Spd) was enhanced... |
