| 摘 要： | 对器官发生途径与体细胞胚胎发生途径的半夏组培苗进行了栽培试验,并记录其生长与繁殖特性.结果显示,通过器官发生途径培养的半夏组培苗与体细胞胚胎发生途径的半夏组培苗相比,具有长势旺盛,丰富的形态变异,较快的生长速度与较强的繁殖能力等特点.此外,采用器官发生途径培养半夏组培苗更快捷,成本更低,更适合大规模农业生产.

| Abstract: | The in vitro regenerated Pinellia ternata plantlets proceeded by the organogenesis way and the embryoid way were transplanted in the flowerpots.Their biological characters were observed,and their tuber growth was recorded.Compared with those by the embryoid way,the in vitro regenerated plantlets by the organogenesis way grew stronger,and showed more morphological variation in the population.Their tuber grew faster,and had higher propogation capacity.In addition,getting the in vitro regenerated plantlets by the organogenesis way could save more time and reagent.The cost was lower.Based on these results,the organogenesis way is considered as the better propogaton method of P.ternata in production practice. |
