Effects of the plant steroidal hormone, 24-epibrassinolide, on the mitotic index and growth of onion (Allium cepa) root tips.
The purpose of the present study was to determine the effects of the steroidal plant hormone, 24-epibrassinolide (BL), on the mitotic index and growth of onion (Allium cepa) root tips. The classical Allium test was used to gather and quantify data on the rate of root growth, the stages of mitosis, and the number of mitoses in control and BL-treated groups of onions. Low doses of BL (0.005 ppm) ...
متن کاملAnalysis of tobacco and smoke condensate for penicillic acid.
Gas chromatographic analyses of smoke condensate from commercial, unfiltered cigarettes spiked with penicillic acid (500 or 1,000 ppm), a reported carcinogenic substance from certain fungi, indicated approximately 3% of unchanged compound was transported in the smoke. Analysis of tobacco on which either Aspergillus ochraceus or Penicillium cyclopium was grown revealed microgram quantities of th...

متن کاملThe Effect of Water Boiled in Aluminum Cookwares on Genomic Abnormalities in the Meristematic Cells of Onion Root
Introduction: One of the ways of human exposure to aluminum (Al) is Al food packaging materials and cookwares. Although many studies have examined the biotic influence of nanoparticles or ionic form of heavy metals, there are limited studies conducted on the possible health risks of metals in the form of alloy used for making utensils. In this study, the effect of water boiled in Al cookwares w...
متن کاملThe reduction of the tumorigenicity of cigarette smoke condensate by addition of sodium nitrate to tobacco.
The tumorigenic activity of cigarette smoke condensate and the concentrations of certain selected chemical constituents in the smoke of cigarettes treated with 8.3% XaNOs are compared with those of a standard (untreated) cigarette. The NaN03 treatment resulted in a significant reduction of particulate matter and also a statistically significant selective reduction of nicotine, phenol, and benzo...
