Summary

Results of the action of low doses of gamma irradiation, intensity 1-80 to 0-24 r/day, are recorded in this paper. Irradiation was carried out on a gamma field with a 0-50 g. equiv. Ra Co60 source throughout the whole vegetative cycle.Trifolium pratense var. Jičínský was chosen as the experimental material. Growth and the yield of green matter was followed both on individually bedded out plants and on sown plots. Results of the measurement and weighing of the plants were statistically evaluated by means of the t-test and analysis of variation. Small, daily radiation doses (1·80-0·30 r per day) produced a significant stimulatory effect which was evidenced in the greater height of the irradiated plants as compared with the controls and a higher yield of green matter. In conclusion the paper deals with work that has already been carried out in this field. Experiments and measurements have shown that low doses of chronic gamma radiation are capable of stimulating plant growth. This work is confirmed by result obtained by Breslavets, Berezina and Shchibrya (1956) on other material.

Souhrn

V práci sú zaznamenanù výsledky sledovania účinku nízkyeh dávok gama žiarenia, intenzít 1,800-0,240 r/den. žEiarovanie bolo prevádazané na kobaltovom poli so žiaričom 0,50 g. ekv. Ra Co60, počas celého vegetačného cyklu. Pokusným objektom bolTrifolium pratense, odrôda Jičinský. Výsledky boli sledované jednak na jednotlivých rastlinách v individuálnej výsadbe a jednak vo výseve. Výsledky z meraní a váení rastlín boli štatisticky zhodnotené pomocou t-testu a analýzy variance. Nízke denné dávky žiarenia (1,8-0,3 /de0148) vyvolali významný stimulačný ôčinok, ktorý sa prejavil vôčšiou výškou ožiarených rastlín v porovnaní s kontrolnými a vôščím výnosom zelenej hmoty. vo výseve bolo pozorované až 40%-né zvýšenie výnosu zelenej hmoty. V závere sú diskutované niektoré práce, ktoré boli vykonané v tomto obore. Pokusy a merania ukázali, že nízke dávky chronického gamma žiarenia môžu vyvolávaf stimuláciu rastu rastlín. Práca je potvrdením výsledkov, ktoré dosiahli Breslavcová, Berezinová a Sčibrja (1956) na inom materiále.
