    Notes: Abstract The effect of gibberellic acid (GA3) on ion ratios in a dwarf maize mutant (Zea mays L. d1) exhibiting normal growth after hormone treatment has been investigated by electron microprobe analysis. Gibberellic-acid treatment increased the ion content in chloroplasts and vacuoles whereas no change of the ion content was found in the cytoplasm. The relation of these observations to the action of the hormone is discussed.

    Early responses to gibberellic acid in a dwarf maize mutant (Zea mays L. d 1) (1977)

    Notes: Abstract Early effects of gibberellic acid (GA3) (1–4 h treatment) on the ion ratios in a dwarf maize mutant (Zea mays L. d 1) showing normal growth after hormone treatment, have been investigated by electron microprobe analysis. GA3 exerts a different effect on the ion ratios in plastids, cytoplasm and vacuoles in short term experiments. The Cl content of chloroplasts and cytoplasm increases without a lag phase after GA3 treatment. The K content of plastids increases after a lag phase of 2 h, whereas in the cytoplasm an increase can be observed immediately after GA3 addition. The hormone has only little influence on the Ca content of the cell compartments investigated. Control experiments with water and the physiologically inactive GA3 methylester confirm the specifity of the short-term actions of GA3 on the ion ratios. The primary action of GA3 at the membrane level is discussed.

    Conduction electron spin resonance in gold (1977)
    Springer
    Journal of low temperature physics 26 (1977), S. 311-316

    Notes: Abstract Conduction electron spin resonance has been observed in transmission through pure gold slabs of 100, 260, and 490 µm thickness covered on each side by a thin ferromagnetic film. This resonance corresponds tog=2.11±0.01 and broadens rapidly above 10 K, in agreement with spin orbit relaxation by phonons.
