Abstract: The effects of low light on dry matter accumulation and macronutrient allocation in tomato were studied in this paper.The results showed that the dry matter accumulation in plant was seriously decreased in light density lower than 50% control condit ion.The absorption of magnesium and potassium by tomato plant was restrained by low light density,only little restrained at nitrogen,phosphorus and calcium.Enhancing application magnesium and potassium fertilizers for the improvement of tomato growth and development in low light density condition was important.The accumulation change of macronutrient were different in root,stem,and leaf.Nitrogen increment rate was the most in leaf,and potass-ium was in root.The decrease of dry matter accumulation was smaller in wild type line than aetiolated type line.

Key words: Low light, Tomato, Dry matter, Macronutrient
