| 摘 要： | 我们对小麦不同品种的幼穗幼茎在不同发育期,不同培养基上进行了2年的愈伤组织诱导及分化实验,并将幼茎与幼穗作了比较。二棱末期至小花分化期是幼穗及幼茎诱导愈伤组织的最适时期。不同品种对培养基的反应不一。不同时期的幼茎愈伤组织只有来源于二棱末期者能够在分化培养基上分化,其它时期者则不分化。品种间分化率差异较大。幼穗的一块愈伤组织可以分化多个苗,而幼茎的一块愈伤组织只发生一个苗。植株再生是通过器官发生的途径。

| Abstract: | The experiment of callus induction and plantlet regeneration from the young stem adjoining the base of the spike has been carried out for two years.The most important factor that determine the callus formation and plant regeneration was the developmental stage of the spike.The varieties of wheat and the compositions of the culture media also influenced the results.While a callus derived from the spike could produce several plan- tlets on the differentiate medium,those from the stem gave always but one and with bigger vigour.The stem derived plantlets differentiated via the path of organogenesis. |
