Problems solved by technology

However, the effects of these chemical germination methods are simply determined after the relevant growth indicators of the young shoots are detected after the seeds germinate.
In fact, the results obtained by this kind of judgment are not scientific and lack of reference significance. This is because even if the detection effect at the young bud stage is good, there will still be many problems in the later development stage.

Abstract

The invention discloses a Xinjiang redroot gromwell seed chemical germination effect judgment method and a germination method. Xinjiang redroot gromwell seeds are treated by a set chemical method andthen germinated in an induced manner. The judgment method includes the steps: measuring SOD (superoxide dismutase), POD (peroxidase) catalase activity of seedlings every day, and measuring correlatedgrowth indexes of the seedlings in the process from seed germination to germination completing; counting measured correlated indexes, performing data processing on the correlated indexes, and judginggermination effect of a current chemical method according to data processing results. Optimal chemical induction germination conditions are determined by the judgment method, and Xinjiang redroot gromwell seeds are germinated in an induced manner according to the conditions. According to the method, Xinjiang redroot gromwell seed chemical germination effect can be most scientifically and accurately judged, judgment results show that the germination rate of the Xinjiang redroot gromwell seeds is best, growth vigor is better, enzyme activity is higher in 30-110mg / L gibberellin, and the gibberellin is suitable for serving as a seed treatment solvent before sowing.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a method for judging the chemical germination effect of Xinjiang comfrey seeds and a germination method of Xinjiang comfrey seeds. Background technique [0002] There are many means of germination of Xinjiang Zicao seeds, among which chemical germination is one of the very commonly used means, including Yu Qiuliang et al. [1] Method, Luo Huiying, etc. [2] Method, Li Cuixiang, etc. [3] , Li Hesheng [4] , crown, etc. [5] and Cheng Lulu [6] method. However, the effects of these chemical germination methods are simply determined after the relevant growth indicators of the young shoots are detected after the seeds germinate. In fact, the results obtained by this kind of judgment are not scientific and lack of reference significance. This is because even if the detection effect is good at the young bud stage, there will still be many problems in the later develo...
