Abstract EN
The incidence of boron (B) toxicity has risen in areas of intensive agriculture close to the Mediterranean sea.
The objective of this research was to study the how B toxicity (0.5 and 2 mM B) affects the time course of different indicators of abiotic stress in leaves of two tomato genotypes having different sensitivity to B toxicity (cv.
Kosaco and cv.
Josefina).
Under the treatments of 0.5 and 2 mM B, the tomato plants showed a loss of biomass and foliar area.
At the same time, in the leaves of both cultivars, the B concentration increased rapidly from the first day of the experiment.
These results were more pronounced in the cv.
Josefina, indicating greater sensitivity than in cv.
Kosaco with respect to excessive B in the environment.
The levels of O2 •− and anthocyanins presented a higher correlation coefficient (r>0.9) than did the levels of B in the leaf, followed by other indicators of stress, such as GPX, chlorophyll b and proline (r>0.8).
Our results indicate that these parameters could be used to evaluate the stress level as well as to develop models that could help prevent the damage inflicted by B toxicity in tomato plants.
