This chapter focuses on the nature and characteristics of ion beam radiation, facilities for plant mutation, ion beam preparation and automatic irradiation system. The biological effects of ion beams and its application in plant breeding are also discussed.

This chapter describes the cytotoxic and mutagenic activities of sodium azide in plants, focusing on the effects of this mutagen on seed germination, growth, cell cycle and metabolism. The interactions of sodium azide with other mutagenic agents, and the effects of these interactions on the performance of sodium azide are also discussed.

The title compound (6) was synthesized by the base-induced condensation of 3-(isocyanotosylmethyl)benzaldehyde as a new bifunctional reactant for the synthesis of [2n]metacyclophanes. The treatments of 6 with silver triflate in several molar ratios in THF at room temperature afforded only 2:1 silver triflate complex on the basis of the 1H NMR and the analytical data.
