Abstract

The present study deals with the effect of different levels of trichoderma fungus on some morpho-physiological, flowering, and biochemical traits of tuberose flower under Drought stress conditions, for which it has conducted an experiment in a factorial based on completely randomized design with three replications at Research Greenhouses of Ferdowsi University of Mashhad during the year 2016. Drought stress treatments of this experiment include irrigation at 100%, 50%, and 25% of field capacity with fungal treatments being composed of three levels of 20%, 10%, and 0% of fungus. Results show that Drought stress has increased the amount of antioxidant, total chlorophyll, and proline. In addition, it has had a negative significant effect on fresh and dry weights of root and biomass, relative water content of leaves, floret diameter, and number of open floret, but Trichoderma has largely moderated these negative effects. The highest amounts of total chlorophyll (1. 04 mg/g leaf fresh weight) and relative humidity of leaf water (85. 2%) belong to 10% level of fungus, which has not differed significantly from the ones at 20% level of fungus. As for the rest of the traits, the highest levels have been found at 20% level of fungus. Since trichoderma fungus, along with reducing the effects of Drought stress, increases vegetative growth and raises the number of open florets (considered an important factor in its marketability) of tuberose flower, its use is quite suggested as a biological factor to increase the quality of tuberose flower in similar conditions.
