| dc.description | Longitudinal pineapple fruit crown sections were irradiated and studied for their rooting ability. Groups of 40 sections each were exposed to gamma-ray doses of 500, 750, 1,000, 1,500, 2,000, 2,500, 3,000, 4,000, 8,000, 16,000 and 32,000 rads in two separate experiments. The treated plant material was propagated, with checks, in sterilized soil in metal flats. The results indicate that at low doses of 500 to 4,000 rads no radiation effect was detected on the rooting of crown sections, proliferation of shoots and shoot stuntiness. Delayed germinal-bud sprouting was observed above 3,000 rads. Exposures to 8,000 and 16,000 rads reduced rooting of crown sections, retarded sprouting of germinal buds, reduced proliferation of shoots, and caused stuntiness in the initial stage of shoot growth. Exposure to 32,000 rads resulted in killing pineapple vegetative tissue. Pineapple appears to be highly resistant to this source of radiation. | en-US |
| dc.description | Se irradiaron secciones longitudinales de la corona de la fruta de la piña y se estudió el efecto radiosensitivo. En dos experimentos separados, se trataron con rayos gamma grupos de 40 secciones cada uno, a dosis de 500, 750, 1,000, 1,500, 2,000, 2,500, 3,000, 4,000, 8,000, 16,000 y 32,000 rads. Posteriormente, el material irradiado se propagó en un suelo esterilizado conjuntamente con el testigo. Los resultados indican que las dosis de 500 a 4,000 rads no afectaron el enraizamiento de las secciones de la corona ni la proliferación y vigor de los hijuelos que de éstas se originaron, aunque las dosis en exceso de 3,000 rads retardaron el brote de las yemas germinales. Las dosis altas de 8,000 y 16,000 rads redujeron el enraizamiento de las secciones de la corona, retardaron el brote de las yemas germinales, redujeron la proliferación de los renuevos y causaron que los hijuelos se achaparraran. El tratamiento de 32,000 rads causó la muerte de todo el tejido vegetativo de la piña. La piña puede considerarse como una planta altamente resistente a la irradiación. | es-ES |
