- 摘要:
- 为了促进桔梗与人参轮作的应用推广，采用培养皿滤纸法研究了人参浸提液对桔梗种子萌发的影响，同时研究了赤霉素对高浓度人参浸提液抑制桔梗种子萌发的缓解作用。结果表明：人参浸提液浓度较低时对桔梗种子萌发并无显著影响，但人参浸提液浓度较高时却抑制了桔梗种子的萌发；赤霉素处理有助于改善高浓度人参浸提液对桔梗种子萌发的抑制，但赤霉素浓度过低或过高都不能克服高浓度人参浸提液对桔梗种子萌发的抑制，当赤霉素浓度为50和60 mg·L-1 时有利于改善高浓度人参浸提液对桔梗种子萌发的抑制，且60 mg·L-1 时效果最佳，不仅能够缓解高浓度人参浸提液对桔梗种子萌发的抑制，而且还改善了高浓度人参浸提液对桔梗发芽长度的抑制现象。总之，低浓度的人参浸提液不影响桔梗种子的萌发，60 mg·L-1赤霉素处理可以缓解高浓度人参水浸提液对桔梗种子萌发的抑制。
- Abstract:
- In order to promote the application of Platycodon grandiflorum rotation with Panax ginseng,the effect of P.ginseng aqueous extract on P.grandiflorum seeds germination was studied by Petri dish filter paper method.At the same time,whether gibberellin can overcome the inhibition of high concentration P.ginseng aqueous extract on P.grandiflorum seeds germination was studied.The results showed that the lower concentration of P.ginseng aqueous extract had no significant effect on the germination of P.grandiflorum seeds,but the higher concentration of P.ginsenga queous extract inhibited the germination of P.grandiflorum seeds; Gibberellin treatment helped to improve the inhibition of high concentration P.ginseng aqueous extract on P.grandiflorum seeds germination,but too low or too high gibberellin concentration can not overcome the inhibition of high concentration P.ginseng aqueou sextract on P.grandiflorum seeds germination,when the concentration of gibberellin was 50 and 60 mg·L-1,it was beneficial to improve the inhibition of high concentration P.ginseng aqueouse xtract on P.grandiflorum seeds germination,and the effect was the best when the concentration of gibberellin was 60 mg·L-1,which not only restored the inhibition of high concentration P.ginseng extract on P.grandiflorum seeds germination,but also improved the inhibition of high concentration P.ginseng aqueous extract on P.grandiflorum germination length.In conclusion,low concentration of P.ginseng aqueous extract did not affect the germination of P.grandiflorum seeds.60 mg·L-1 gibberellin treatment restored the inhibition of high concentration of P.ginseng aqueous extract on the germination of P.grandiflorum seeds.
