Abstract

Potted miniature rose (Rosa ‘Fiesta Parade (POUlesta)’) were cultivated under supplementary lighting, shading and natural condition in autumn, spring and summer. The plant height and the fresh weight of shoots under supplementary lighting were significantly higher than those under control. The growth under shading was inhibited in autumn cultivation, and there were significant differences between shading and control in the leaf area, the number of leaves, the plant height and the fresh weight of shoots. However, these differences under shading and control were small in summer and spring cultivation. There were most flowering shoots in summer cultivation, and the number of flowering shoots decreased in order of spring and autumn cultivation. Regardless of seasonal cultivation, there were few flowering shoots significantly in a shading division. The multiple regression equation of leaf area, leaf number, plant height and fresh weight of leaves, plants, which was calculated using the cumulative daily solar radiation, the cumulative daytime temperature and the cumulative nighttime temperature as explanatory variables, showed 0.9 or more multiple correlation coefficients, and was significant. Significant positive correlation in supplementary lighting and shading was between the observed growth and the predicted growth presumed using the multiple regression equation calculated from in control. And inclination of each correlation equation was 0.930-1.013 in the supplementary lighting, and was 0.930-1.013 in the shading division. Therefore, it was able to predict the growth of potted miniature rose controlled the light and temperature by the application of the multiple regression equation calculated in control.
