EFFECT OF IRRIGATION AND SHADING AT THE STAGE OF FLOWER BUD APPEARANCE |
| Author: | D. Chimonidou-Pavlidou |
| Abstract:
Macroscopic observations showed that the stem length as well as the time to reach the different stages of rose development externally was affected by the irrigation and shading treatments applied. Although there was not any effect due to irrigation or shading on the first stages of development acceleration of flower bud appearance was observed on the flowering shoots under the most severe irrigation treatment. Flowering shoots under this treatment, irrespective of shading, reached the stage of flower bud appearance earlier with a shorter stem length compared to the flowering shoots under the less severe treatment. However, observations under the scanning electron microscope of samples originated from different irrigation and shading treatments, showed that the subsequent development was the same under all irrigation and shading treatments. It appears that water stress imposed, affected only growth and not development. | |
