Salt tolerance of four tomato hybrids
- 233 Downloads
A greenhouse lysimeter experiment was conducted to evaluate the response of tomato hybrids to varying levels of salinity. Four tomato hybrids F-172, F-150, Bornia and Diego were grown at four salinity levels.
The soil was salinized prior to transplanting by irrigating with waters that were prepared by adding NaCl to the tap water. The electrical conductivities of the irrigation waters were 1.8, 4.5, 7.0, and 9.5 dS/m at 25°C.
Yield, fruit quality, and leaf mineral composition were measured. Fifty percent fruint yield reduction for all hybrids was associated with a soil salinity of 5.1 dS/m. Each unit increase in salinity above 2 dS/m reduced yield by 14%. This indicates that these tomato hybrids are more salt sensitive than the older varieties. Fruit quality and leaf mineral composition were also affected by salinity and hybrid.
