Sa. Stanko, INTENSE INTERRUPTED WHITE-LIGHT AS A FACT OR OF INCREASED ADAPTIVE INTRODUCTION AND MUTAGENESIS OF THE WHEAT, Izvestia Akademii nauk SSSR. Seria biologiceskaa, (5), 1994, pp. 788-801
Illumination of seeds and apical meristems of short-day dwarf wheat by
intense interrupted white light changes the adaptive basis of their p
hotoperodic responsiveness and provides for adaptive introduction in r
egions with a long photoperiod. Intense interrupted while light activa
tes structural-metabolic, photoenergetic and mutation processes and in
duced photodestruction and photoinactivation of the endogenous inhibit
ors and favors formation of photoinduced free radicals. Some free radi
cals form peroxide and hydroxyl radicals in the aqueous phase of cells
, which a strong mutagens inducing point (genic) mutations. About 65%
of morphogenetically constant highly productive photomutant forms havi
ng an improved quality of grain and well adapted to a long photoperiod
have been selected in the 2nd - 5th generations.
