Harmful Effects

Trichoderma is used as crop growth promoters. However, they may have harmful effects at higher concentrations. The objective of this work was to evaluate the vermicompost effect formulated with different concentrations of sandy soil, bioenriched with higher than recommended doses of trichoderma, on the germination, initial development and chemical composition of the cherry tomato Creole shoot. The treatments (T) used were substrate composed of vermicompost and sandy soil at 25 kg kg-1 (low), 50 kg kg-1 (medium) and 75 kg kg-1 (high), respectively. The Ecotrich bioproduct was added to the substrate at the following concentrations T1) 0.0; T2) 108; T3) 109; T4) 1010 cfu L-1. Afterwards, three cherry tomato seeds were sown per cell in trays containing the mixture, totaling 90 seeds per treatment. At 30 DAS, height, stem diameter, chlorophyll a, b and total, fresh and dry root and shoot phytomass, root volume and area, leaf area and leaf chemical analysis were evaluated. Bioproduct concentrations, compared to control without trichoderma, did not provide superior results for shoots and roots at 30 DAS. However, plants cultivated with higher concentration of vermicompost were less negatively affected at higher doses of the bioproduct.

<p>An experiment was carried out to determine the effect of foliar application of seaweed extract (0.2 %) on the growth, yield and quality of cherry tomato under stress and non-stress conditions. The greenhouse experiment was set up in a randomized block design with four treatments in three replications. Treatments were as follows: V<sub>1</sub> - seedlings treated by seaweed extract and subjected to drought; V<sub>2</sub> - seedlings treated by seaweed extract and regularly watered; V<sub>3</sub> - non-treated seedlings subjected to drought; V<sub>4</sub> - non-treated seedlings regularly watered. Cherry tomato seedlings treated by seaweed extract had a lower content of proline and higher leaf water potential compared to non-treated seedlings under stress conditions, indicating that application of this fertilizer contributes to better adaptation of cherry tomato seedlings to stress. Treatment with seaweed extract also positively influenced the yield and quality of cherry tomato (total soluble solids, vitamin C, lycopene) under both standard and drought stress conditions as compared to untreated plants in same conditions. Positive effects of seaweed extract on growth and quality of cherry tomato are result of its specific composition, as well as ability of cherry tomato plants to utilize bioactive substances in seaweed extracts for its growth and development.</p>

The aim of this study was to examine the impact of different liquid fertilisers on selected physiological parameters in order to evaluate the drought tolerance of cherry tomato seedlings. The following physiological parameters were investigated: total phenolic and flavonoid content, total antioxidant capacity and proline content of leaf extracts. Total phenolic and flavonoid content were determined using the Folin-Ciocalteu and aluminium chloride colorimetric methods, respectively. The ferric-reducing/antioxidant power (FRAP assay) was used to measure the total antioxidant capacity, while proline content was evaluated according to the method of Bates. The contents of proline, total phenolics and flavonoids were significantly higher in the leaves of cherry tomato seedlings exposed to water stress, which suggests that the higher synthesis of these substances by plants represents an important defence mechanism of drought tolerance. The results also indicate that the application of all the used fertilisers in accordance with the manufacturer’s instructions can significantly increase the content of phenol compounds and total antioxidant capacity of plants under normal growth conditions, thus improving survival under subsequent stress.
