Preliminary study on the effect of x-ray irradiation on Capsicum annum
The present experiment on Capsicum annum was conducted to study various cytological and genetic effects induced by x-ray irradiation. Dry and soaked seeds were exposed to irradiation by deep x rays at the Radium and Cancer Research Institute, Hyderabad at a dose rate of 99 rads/min. The doses administered were as follows: 3000 rads, 4000 rads, 5000 rads, and 10,000 rads. The cytological preparations were made by following Belling's technique. The irradiated seeds along with the controlled were sown in the soil to observe the morphological variations. The root tip squashes from the irradiated seed material revealed various chromosomal aberrations such as deletions, parallel bridges, and single and paired fragments of acentric chromosomes, showing cytological irregularities. Bridges were quite common at anaphases. The irradiated seeds were germinated in order to record morphological variations. A period of 150 days seems to be necessary from germination to seed formation; this period is not identical for the irradiated and controlled seeds. In some of the irradiated material the duration was reduced to 120 to 130 days. With this observation it may be presumed that mild doses of radiation have accelerated the germination time and also hastened the growth processes. (auth)
