Shades of different light intensities (29%, 43%, 54%, 60% or 68%) along with control (no shade) were studied to observe their effects on the flowering time and plant quality. A hyperbolic relationship was observed between different light intensities under shade, and time to flowering. The total number of flower buds showed a curvilinear relationship with light intensities. Growth parameters related to the plant characteristics such as plant height, leaf area and plant fresh weight were improved under shading treatments at the expense of flowering time and number of flower buds. However, both linear and polynomial models applied assumed that cultivar Chimes White was equally sensitive to light intensity throughout development. 相似文献

Shades of different light intensities (29%, 43%, 54%, 60% or 68%) along with control (no shade) were studied to observe their
effects on the flowering time and plant quality. A hyperbolic relationship was observed between different light intensities
under shade, and time to flowering. The total number of flower buds showed a curvilinear relationship with light intensities.
Growth parameters related to the plant characteristics such as plant height, leaf area and plant fresh weight were improved
under shading treatments at the expense of flowering time and number of flower buds. However, both linear and polynomial models
applied assumed that cultivar Chimes White was equally sensitive to light intensity throughout development. 相似文献
