SALOMON DIAZ, Jorge L; GONZALEZ CEPERO, María C; CASTILLO HERNANDEZ, Juan G  e  VARELA NUALLES, Mario. Effect of gamma rays on the germination of botanical potato seed (Solanum tuberosum L.). cultrop [online]. 2017, vol.38, n.1, pp. 89-91. ISSN 1819-4087.

This paper aims to evaluate the effect of differents rates of 60 Co gamma rays to stimulate germination in botanical potato seed (Solanum tuberosum L.) with very low germination rates. The progeny seeds Atzimba x TPS-13 from the International Potato Center (CIP) in Perú, were irradiated with doses of 10 to 100 Gray (Gy) at intervals of 10 Gy and unirradiated control. It was found that not all doses stimulate the germination of potato seed, a result that could be in agreement with those presented in radiosensitivity studies for both stimulating germination and to increase the genetic variability in crops. The dose 20 Gy showed the greatest stimulation of seed germination
