Gaseous exchange and photosynthetic efficiency of fertigated indeterminate tomatoes (Solanum lycopersicum)

Trellising is one of the most important horticultural practices used during the growth and development of tomatoes produced in tunnels and open fields. The effect of different trellising methods was investigated on leaf gaseous exchange and photosynthetic efficiency of fertigated indeterminate tomatoes (Solanum lycopersicum) grown in a dome-shaped tunnel.

Abstract

Trellising is one of the most important horticultural practices used during the growth and development of tomatoes produced in tunnels and open fields. The effect of different trellising methods was investigated on leaf gaseous exchange and photosynthetic efficiency of fertigated indeterminate tomatoes (Solanum lycopersicum) grown in a dome-shaped tunnel. The experiment was laid out as a randomized complete block design with three treatments, namely, vertical, early layering and late layering trellising methods. The results showed significant differences (p < 0.05) amongst the different trellising methods in photosynthetic rate (Pn), intercellular CO2 concentration (Ci), the ratio of intercellular and atmospheric CO2 concentration (Ci/Ca), stomatal limitation, transpiration rate (T), water use efficiency, the maximum quantum efficiency of photosystem II photochemistry (Fv/Fm), effective quantum efficiency of photosystem II photochemistry (ϕ PS II), photochemical quenching (qP), electron transportation rate, maximum fluorescence and proportion of open reaction centers (1-qP), indicating variability among tested trellising methods. The findings on leaf gas exchange and chlorophyll fluorescence revealed that early and late layering trellising methods improved photosynthetic efficiency than vertical trellising. Therefore, these results provide some evidence that early and late layering trellising methods are the best methods that can be used by resource-constrained farmers in dome-shaped tunnels to improve the physiological efficiency of indeterminate tomatoes.
