Biological effects of a chemical mutagen, diepoxybutane, on tomato.

Tomato seeds were treated with three concentrations of 1:2, 3:4-diepoxybutane. Seedling mutations were induced in high amounts with all doses, but other biological effects in the treated generation including delayed germination, chlorophyll-deficiency sectoring in the first true leaves, and failure of plants to bear fruit, were found only with the highest concentration. Neither a lethal nor a partially lethal dose was applied.
