Embryo development and metabolic activity (RNA- and DNA-synthesis) were studied in relation to changes in sensitivity to gamma radiation and the chemical mutagens, ethylmethanesulfonate (EMS) and methylmethanesulfonate (MMS). During the initial stage when swelling and elongation of the embryo took place, the sensitivity to EMS and MMS was decreasing. In the second stage with higher metabolic activity the sensitivity to gamma radiation and the mutagen increased slowly. In the third stage the sensitivity increased proportionally with the rapid increase of DNA-synthesis in the embryos.","PeriodicalId":270267,"journal":{"name":"Japanese journal of breeding","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1970-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126585955","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}

The study was done in comparison with the Japanese corresponding species, E. papyrifera.

The general morphological characteristics of the Himalayan species are almost similar to the Japanese species which is usually tetraploid, but the former has larger and thicker leaves and is evergreen while the Japanese species is deciduous. When the Himalayan species is compared with the artificially induced Japanese octoploid plants, it has. larger stomata cells, more chloroplasts in them and longer hairs on the leaves, but shorter fibre cells in the bark which are most important for paper materials.","PeriodicalId":270267,"journal":{"name":"Japanese journal of breeding","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1966-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124921500","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}
