The results showed that: 1) Eucalyptus litter extract had a concentration effect of “low promotion and high inhibition” on the allelopathy of seed germination and seedling growth of Z . insignis . In the mass concentration range of 0 g/mL~0.05 g/mL, it had a certain promoting effect on the seed germination and seedling growth of Z . insignis ; When the concentration exceeds 0.10 g/mL, it has a significant inhibitory effect on the germination and seedling growth of Z . insignis seeds. 2) According to the calculation results of the comprehensive allelopathy index, the allelopathy of Eucalyptus litter extract on the seed germination of Z . insignis is greater than its allelopathy on the seedling growth of Z . insignis . Due to the relatively small impact of liquefied substances extracted from Eucalyptus litter on seed germination and seedling growth of Z . insignis , it is theoretically feasible to use Z . insignis as a mixed tree species in Eucalyptus plantations for stand transformation.","PeriodicalId":9237,"journal":{"name":"Botanical Research","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83772764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, five hundred and twenty-seven single nucleotide polymorphic characters from the complete chloroplast genomes were used for the first time as molecular traits to identify Larix plants and compile a molecular classification key. There are differences in aspects of single nucleotide polymorphic characters between species and varieties. Among the eight species/varieties, L. himalaica W. C. Cheng & L. K. Fu, L. sibirica Ledeb . and L. deciduas Mill . has larger number of diverged single nucleotide characters. Genetic variation levels among the four genotypes as named L. gmelinii (Rupr.) Kuzen. var. gmelinii , L. gmelinii var. olgensis (A. Henry) Ostenf. & Syrach, L. gmelinii var. japonica (Maxim. ex Regel) Pilg. and L. cajanderi Mayr are comparatively low.
