Abstract:

The effects light quality and fertilizer concentration on seedling growth of Primula forbesii were studied. The results showed that blue light could enhance photosynthetic rate and transpiration rate of seedlings, yellow light significantly increase seedling height, and red light promote flowering. There were the best effects of seedling growth and increased leaf area with fertilizer concentration of EC 2.0 mS cm^-1. When treated with red light and EC 2.0 mS cm^-1 fertilizer, the vegetative and reproductive growth of seedlings enhanced. It suggested that suitable light quality and fertilizer could promote plant growth.

Key words:Primula forbesii;Light quality;Fertilizer;Growth and development
