Review of Dry Matter Production and Light Interception by Plants for Yield Improvement of Greenhouse Tomatoes in Japan

Abstract

The fresh fruit yield of tomatoes (Solanum lycopersicum L.) is determined by yield components and related traits. In a low-truss cultivation in Japan, there was no significant difference in light use efficiency between different planting densities and stages. Accordingly, dry matter production is described by a function of intercepted light: Total dry-matter production = light use efficiency × Intercepted light. Light interception is determined by leaf area index (LAI) and the light extinction coefficient in the plant canopy.
