Cyto genetic effect of certain chemical mutagens on norway spruce
Tsitologiya i Genetika 10(1): 61-63
The cytogenetic effects of chemical mutagens NMU [N-nitroso-N-methylurea], NEU [N-nitroso-N-ethylurea], NDMU [N-nitroso-N,N'-dimethylurea] DMS [dimethylsulfate], EI [ethylenimine], and DAB [1,4-bis-diazoacetylbutane] on Picea abies were investigated. Some doses NMU and DAB produced a more active mitotic division of cells. In most cases the frequency of chromosome aberrations was quite high.
