Abstract
|
|
|
|
The germination rate of radishes grown with the far infrared irradiated water and drinking water was 100% and 78% respectively. The far infrared irradiated water stimulated the cell division of the cotyledons and enlarged the cell sizes both in the dark and in the light. In the dark and light conditions, the size of the cotyledons of transversal axis and longitudinal axis grown with the far infrared irradiated water was bigger than that grown with the drinking water. The content of chlorophyll and the consumption of CO₂ of the cotyledons grown with the far infrared irradiated water were higher, respectively. Osmotic pressure of the cotyledons grown with the far infrared irradiated water was 1.25 factors higher than that grown with the drinking water. The water potential of the cotyledons grown with the far infrared irradiated water was more negative value. The length of hypocotyls grown with the far infrared irradiated water was 2.18 factors longer in the dark, 1.99 factors longer in the light than that grown with the drinking water and the radish roots grown with the far infrared irradiated water were larger, respectively.
