Estudio de radiosensibilidad en la germinación y crecimiento de la arveja Pisum Sativum L, con semillas expuestas a radiación gamma utilizando un irradiador de Co-60.

Abstract

Knowledge of the physiology of crops, their needs and their physical interaction with the environment is important, as this allows to provide the right amount of nutrients, for some time ago has been investigating how to improve pea seeds without using substances Chemical, since these could be cause of diseases, the investigation of better methods of production can guarantee the food sovereignty with healthy foods and without side effects. The use of new methods such as irradiation of the seeds to determine the radiosensitivity of the same allows to expand future scientific investigations in this field, the objective of this work is to analyze the physiological effects on the germination and growth of the pea Pisum Sativum L, with Seeds exposed to gamma radiation using a 60Co irradiator. The experiment consists of irradiating 10 samples at different doses each, then the seeds are sown to the irradiated seeds, to take the data, continuous observations are made. After data collection by observation, the effects of irradiation during germination and seed growth can be realized that at doses between 20 -100 Gy germinate and grow more than 50% of the seeds and between 120 - 200 Gy germinate and grow less than 50% of the seeds. In conclusion the dose between 20 - 60 Gy are the most effective, since at these doses the seed shows improvement in the physical characteristics of the pea plant, compared to the control.
