Abstract
Drought stress affects many morphological characteristics and biochemical processes related to plant growth and development. In this sense, drought, as a multidimensional stress, has various destructive effects on plants. By inhibiting the transfer of electrons, this stress creates a secondary stress in the production of reactive oxygen species, causing double damage to the cell membrane, photosynthetic pigments, and other physiological parameters. Today, the use of metal nanoparticles such as zinc and iron in improving activities and dealing with plant stresses can create beneficial effects in plant and agricultural biotechnology. The treatments include drought stress at two levels (drought stress and no drought stress) as the main factor and three levels of iron, zinc separately and integrative of iron and zinc nanoparticles. The results showed that all investigated traits were affected by drought stress conditions, so that under drought stress the fresh and dry weight. Chlorophyll a and b, decreased and the usage of iron and zinc nanoparticles reduced the effects of drought stress in mentioned growth parameters in tomato plants. Therefore, the application of the above nanoparticles can be very effective in improving the growth of tomato plants, especially in dry areas.
