However, the effect of this agent on the cell cycle and optimum time of treatment during the cell cycle in these studies is not known. To better understand the effects of sodium azide on the embryonic barley shoot cells, a detailed study of the effect of azide on the cell cycle was conducted.Himalaya barley seeds were treated for 2 hr with 10−4, 5 × 10−4, and 10−3M oxygenated sodium azide solutions at pH 3. The principal effect on the cell cycle due to sodium azide treatment was a delay in the initiation of metabolism following germination. This resulted in a uniform delay in the following parameters: mitotic activity, seedling growth, and ATP and DNA syntheses. This delay was interpreted as being due to an ATP deficiency which when alleviated allows the cells to progress normally through mitosis.Chromosome damage caused by sodium azide was not reflected in the seedling heights as the reduction in height was due entirely to mitotic delay. No variation occurred in the progression of cells through mitosis between various regions of the shoot within the first 29 hr of germination.</div>","PeriodicalId":20794,"journal":{"name":"Radiation Botany","volume":"15 4","pages":"Pages 315-322"},"PeriodicalIF":0.0,"publicationDate":"1975-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0033-7560(75)90002-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72610160","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}

However, increasing the straw levels, without fertilization, in the Blaine Lake soil contaminated with either 137cesium level, did not appreciably and consistently affect the 137cesium uptake by the plants.Plants absorbed highly significantly greater 137cesium from the 100 compared to the 50 μCi 137cesium level in both the soils applied with any straw-fertilizer combination.

No significant changes in production were determined during the irradiation year. One year later three distinct zones—semi-devastated, herbaceous, and original forest—developed along the radiation gradient. Biomass production under forest canopies decreased significantly in the semi-devastated zone, increased significantly in the herbaceous zone (primarily responding to additional light), and remained unchanged under the original forest. Logging road vegetation responded similarly but the changes were restricted within higher radiation doses. At comparable levels of radiation, production of species of the logging road vegetation was affected less than that of species under forest canopies. Such a trend was predictable from the generally smaller interphase chromosome volumes, ICV's, of the species on the logging road and from their ability to survive in severe habitats.</div>","PeriodicalId":20794,"journal":{"name":"Radiation Botany","volume":"15 4","pages":"Pages 337-348"},"PeriodicalIF":0.0,"publicationDate":"1975-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0033-7560(75)90005-8","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83977146","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}
