Automated Pruning of Greenhouse Indeterminate Tomato Plants
<p>Pruning of indeterminate tomato plants is vital for a profitable yield and it still remains a manual process. There has been research in automated pruning of grapevines, trees, and other plants, but tomato plants have yet to be explored. Wage increases are contributing to the depleting profits …

The Potential Interaction of Salmonella enterica and Ralstonia solanacearum in Tomato Plants
… four outbreaks of Salmonellosis associated with tomato all originating from the same strain, Salmonella enterica serovar Newport. In addition to S. Newport contamination, the devastating plant disease, bacterial wilt, caused by the phytopathogen Ralstonia solanacearum threatens the sustainability …

Evaluation of the Pseudomonas mediterranea UFV potential to control bacterial diseases of tomato plants
… products to control bacterial diseases of tomato, the focus of this work was to generate information on the potential of P. mediterranea UFV (Pm UFV) and the compounds produced by this strain in controlling tomato diseases caused by bacteria. The content of chapter 1 includes in vivo trials …

Impacts of flooding, herbivory and their interaction on tomato plants growth, development and physiology: A review
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2023-12-04 without embargo terms

Enhancement of cold tolerance and growth of tomato plants using endophytic bacteria isolated from cold-adapted plants
… as commercial greenhouses and tunnels used for tomato production in Sicily. However, temperature conditions are not constant under commercial greenhouse conditions, and cold stress damage can occur. Microbial communities associated with plants in cold environments can enhance plant growth at low …

Association of Salmonella enterica serotype Newport with Tomato Plants through Irrigation Water, Grown under Controlled Environmental Conditions
Tomato fruit have been associated with numerous outbreaks of salmonellosis in recent years. Trace back suggests tomato fruit may become contaminated during pre-harvest, however exact routes are unclear. The objective of this study was to determine the potential for Salmonella enterica serotype …

Effects of Increased Atmospheric Carbon Dioxide Levels on Tobacco Mosaic Virus and Root-Knot Nematodes in Genetically Resistant and Susceptible Tomato Plants
… in genetically resistant versus susceptible tomatoes (<em>Solanum lycopersicum</em>). Both resistant and susceptible tomatoes were grown in chambers with either ambient CO<sub>2</sub> or CO<sub>2 </sub>elevated to 750 ppm and infected with <em>M. arenaria</em> or TMV. Measurements were taken …

Inhibition of Photosynthesis in Whole Tomato Plants Following Chilling in the Light: The Role of Enzymes of the Photosynthetic Carbon Reduction Cycle
Certain plants which are accustomed to growing under temperate conditions show a distinct inhibition of function when subjected to brief periods at temperatures that are well below the optimal growing point but above freezing. Photosynthesis is often the first physiological process that displays a …

Investigating the physiological and metabolomic effects of Ecklonia maxima-derived biostimulant foliar application in ameliorating the effects of heat shock in tomato plants
Tomato (Solanum Lycopersicum) is a globally popular horticultural commodity with great economic importance and is highly susceptible to heat shock and heat stress. Heat shock has evidenced detrimental effects on plant viability and growth, limiting crop productivity and quality. In addition to …

Interaction of tomato plants infected by the nematode Meloidogyne javanica on aboveground herbivore Tetranychus urticae and on behaviour of its predator Phytoseiulus macropilis
… with their hosts. By inducing defenses, plants respond to herbivore attacks, may affect your development. The general objective of this research was to investigate the effect of the nematode Meloidogyne javanica on the performance of the herbivore Tetranychus urticae in tomato plants and, …

CMV Infection Affects Bumblebee Pollination Behaviour and Plant Reproductive Success
… work in the lab suggested that VOCs emitted by tomato (Solanum lycopersicum) plants infected with cucumber mosaic virus (CMV) were more attractive to bumblebees (Bombus terrestris) in free choice assays. I extended this work using Arabidopsis thaliana mutants with lesions in genes encoding …

Chemical weed control in transplanted tomatoes
Weed control in transplanted tomatoes with diphenamid, trifluralin, and paraquat was evaluated under field conditions on a predominantly Grosclose silt loan soil on the Virginia Polytechnic Institute Horticulture farm near Blacksburg, Virginia. The herbicides were used singularly and in certain …

Mikrobielle Ökologie N-Acyl-L-Homoserinlacton-produzierender Bakterien in der Rhizosphäre von Tomatenpflanzen
… Pseudomonas putida IsoF in the rhizosphere of tomato plants. Gfp- and rfp-tagged strains of the AHL producing wiltypes S. liquefaciens MG1 and P. putida IsoF were compared with its AHL-negative mutants, which were unable to produce AHL. Two kinds of plants cultivating systems were used: a …

Chemical synthesis, cloning and expression of a gene encoding systemin, a proteinase inhibitor-inducing factor
Wound-inducible proteinase inhibitors in plants elicit a defence mechanism by inactivating the proteinases of insects. This triggers a feedback mechanism causing overproduction of digestive enzymes together with a decrease in appetite, leading to starvation. System in, a polypeptide proteinase …

SALT EXPOSURE AND NITROGEN METABOLISM IN TOMATO (SOLANUM LYCOPERSICUM L.): IMPROVEMENT OF THE RESILIENCE TO ABIOTIC STRESS
… an in-depth understanding of the mechanisms plants employ to adapt to saline environments. Nitrogen (N) metabolism plays a pivotal role in regulating plant responses to salinity, with complex interactions between salt stress and nitrogen availability influencing plant physiology and …

Soilless media for seed germination and growth of tomato transplants, and for the rooting of certain herbaceous stem cuttings
… results from the germination and growth study of tomato plants. Weblite was a constituent of the seven best media for germination. Tomato plants grown in media containing vermiculite had the highest dry weights. Chrysanthemum morifolium cv Sunny Mandalay stem cuttings were rooted in six media. …

Virus-induced effects on aphid-host interactions in Solanaceous plants
… migration of viruliferous aphids from infected plants to healthy plants. In tomato (Solanum lycopersicum), a model species and economically important crop, viral modification of vector-host interactions for non-persistently transmitted viruses is understudied. I investigated CMV-induced effects …
