Abstract
The complex response of plants to ionizing radiation has never been clearly understood. One of the main problems is the differential sensitivity of plants to radiation. A clear understanding of differential sensitivity lies far in the future. For the present a major question is: can we predict the radiosensitivity of a plant before radiation exposure? Some progress has been made in answering this question. Sparrow et al. (29) feel that they have a useful statistic which can be used to predict the approximate radiosensitivity of a plant. Average interphase chromosome volume has been tested on sixteen species of herbaceous plants (29) and twelve species of woody spermatophytes (30). In all cases, this value has proved to be a useful statistic for predicting radiosensitivity. The present investigation extends the study to see if average interphase chromosome volume can be used as a valid index of the approximate radiosensitivity of native forage grasses.
