Chlorophyll mutations after low doses of chronic irradiation of barley

Chlorofylové mutácie u jačmeňa po malých dávkach chronického žiarenia

Хлорофилльные мутацип у ячменя, возникшие в результате хронического облучения растений небольшими дозами

  • Published:
Biologia Plantarum

Abstract

The chlorophyll mutation rate on a large number of plants after the dose rates 0·004–16·800 R/day during the whole vegetation cycle was examined. The mutation frequency increases as early as after the dose rate 4 mR/day. The dose rate of approximately 8 mR/day is necessary to double the mutation frequency.

Abstract

Na vel'kom počte rastlín sme sledovali výskyt chlorofylových mutácií u jačmeňa v potomstve rastlín exponovaných celou vegetačnou dobu na gama poli dávkami 4 mR–16,8 R/deň. Už po dávke 4 mR/deň sme zaznamenali stúpanie frekvencie mutácií. K zdvojeniu celkového množstva mutácií bola potrebná dávka 8 mR/deň.

Abstract

На большом количестве растений изучали появление хлорофилльных мутаций у ячменя в потомстве растений облученных дозами 4 мР–16,8 Р/день в течение всего вегетационного периода на гамма поле. Повышение частоты мутаций обнаружено уже при дозе 4 мР/день. Общее количество мутаций увеличилось вдвое при дозе 8 мР на день.
