摘要:
四倍体甜叶菊相比二倍体植株具有营养器官巨大、活性成分含量高、抗逆性强等显著特征。扦插是四倍体植株繁殖的主要途径，该试验研究用不同植物生长调节剂处理对四倍体甜叶菊扦插生根的影响。分别用NAA，ABT和GA33种植物生长调节剂对四倍体甜叶菊“守田3号”插穗进行处理，采用双因素(不同质量浓度和不同处理时间)完全重复试验，对试验结果进行方差分析、多重比较。结果表明：综合生根率、生根数、根长3个指标分析，利用NAA最佳的处理为NAA质量浓度600 mg/L+浸泡20 min，利用ABT处理促进生根的最佳组合为ABT质量浓度1 000 mg/L+浸泡25 min，利用GA3处理最佳组合为GA3质量浓度100 mg/L+浸泡 10 min。
Abstract:
Compared with diploid plants, tetraploid Stevia rebaudiana has significant characteristics such as huge nutritional organs, high content of active ingredients, and strong stress resistance. Cutting propagation is the main way for tetraploid plant propagation. Studying the effects of different hormone treatments on the rooting of tetraploid stevia cuttings is of great significance for accelerating the rapid propagation. In this experiment, three hormones, NAA, ABT, and GA3, were used to treat the rooting of tetraploid S. rebaudiana ‘Shoutian 3’ cuttings. Different concentration and treatment time factors were designed in the fully repeated experiment. The experimental results showed that the optimal treatment for comprehensive rooting rate, rooting number, and root length using NAA was 600 mg/L followed by soaking for 20 minutes. The optimal combination for promoting rooting using ABT treatment was 1 000 mg/L followed by soaking for 25 minutes. The optimal GA3 treatment was 100 mg/L followed by soaking for 10 minutes.
