Abstract

This article explored the effects of plasma pre-treatment on the germination of Platycodon grandiflorum seeds. By analysing the effects of plasma pre-treatment on the germination, seedling growth and development of P. grandiflorum seeds, the study explored the best technological parameters of plasma pre-treatment for P. grandiflorum production and application, and promoted the application of plasma technology in the seed pre-treatment of P. grandiflorum. Based on field experiments, this study verified that plasma pre-treatment can have positive biological effects on P. grandiflorum. The Boltzmann equation was used to fit the germination-time process curve and the logistic equation was used to fit the growth-time process curve. According to the fitted equations, the prediction of the germination stage and the true leaf stage of P. grandiflorum were realised. Plasma pre-technology can increase the field germination of P. grandiflorum seeds by 23.9%. Furthermore, the growth advantage of P. grandiflorum during the germination period is maintained through to the true leaf stage. Plasma pre-treatment significantly shortened the time for P. grandiflorum seedlings to reach the true leaf stage and promoted growth and development.

血浆预处理对桔梗田间萌发和幼苗生长的影响

本文探讨了血浆预处理对桔梗种子萌发的影响。通过分析等离子体预处理对桔梗种子萌发、幼苗生长发育的影响，探索桔梗生产应用等离子体预处理的最佳工艺参数，促进等离子体技术在桔梗种子预处理中的应用。通过田间试验，验证了血浆预处理对桔梗具有积极的生物学效应。用玻尔兹曼方程拟合发芽时间过程曲线，用logistic方程拟合生长时间过程曲线。根据拟合方程，实现了桔梗萌发期和真叶期的预测。等离子体预处理能使桔梗种子的田间发芽率提高23.9%。此外，桔梗在萌发期的生长优势一直保持到真叶期。血浆预处理显著缩短了桔梗幼苗到达真叶期的时间，促进了其生长发育。
