The Influence of Gamma-rays on the Injury and Chromosomal Aberrations of Long Bean (Vigna sesquipedalis, Fruw.)
The effects of gamma-rays on three varieties of long bean (Vigna sesquipedalis, Fruw), namely Melaka, Local Black and Local Long were studied using Jive doses ranging from 10 to 50 kR. Both Chromosomal aberrations and characteristics related to physiological damage were used to study radiation se...

The effects of gamma-rays on three varieties of long bean (Vigna sesquipedalis, Fruw), namely
Melaka, Local Black and Local Long were studied using Jive doses ranging from 10 to 50 kR. Both
Chromosomal aberrations and characteristics related to physiological damage were used to study
radiation sensitivity of the varieties. In general, gamma radiation did not affect % seed germination
but caused a significant reduction in characteristics related to survival, growth and fertility. Percentage
chromosomal aberrations also increased with increasing dose. As the measurement of seedling
height is simple, quick and highly correlated with most characteristics studied, it could be a useful
parameter in the study of radiation effects on long bean. Using a critenrion of approximately 30%
reduction in seedling height or 50% lethality, it is suggested that doses ranging from 30 to 50 kR
would be suitable for mutation induction in long bean. |
