Red light promotes compact growth of sunflowers
Light quality affects plant morphology. Hence, light quality is an important factor in the cultivation of ornamental plants. The recent advances in LED technology allow producers to adjust light quality to manipulate plant growth. For growers of ornamental plants the primary aim regarding plant morphology is to keep plants short and compact with attractive flowers. However, data on the effect of light quality on plant morphology are still sparse. This study provides data on the effect of different LED light regimes on height and fresh weight of shoot and flower, leaf area and compactness of the model plant Helianthus annuus. Regression analysis of these data shows that red light promotes compact growth.
