Thermal Ionisation Mass Spectrometry (TIMS) was applied to discriminate a total of 118 tomato samples (berries, "passata", tinned tomatoes, sauce, double and triple concentrate) coming from two different countries. The TIMS technique gave significantly different results for the (87)Sr/(86)Sr ratios and δ‰ values between Chinese and Italian tomato samples, irrespective of the treatment type. Thi...

Variation in resource inputs to plants may trigger bottom-up effects on herbivorous insects. We examined the effects of water input: optimal water vs. limited water; water salinity: with vs. without addition of 100 mM NaCl; and their interactions on tomato plants (Solanum lycopersicum), and consequently, the bottom-up effects on the tomato leaf miner, Tuta absoluta (Meytick) (Lepidoptera: Gelec...

Vermicompost has been promoted as a viable alternative container media component for the horticulture industry. The purpose of this research was to investigate the use of vermicompost at different points in the production cycle of tomato, marigold, pepper, and cornflower. The incorporation of vermicompost of pig manure origin into germination media up to 20% v/v enhanced shoot and root weight, ...

Engineering and horticultural research efforts aimed at developing an innovative, controlled environment, plant production system have been completed. In this production system, tomato plants are made transportable and each plant is allowed to produce only one truss of fruit. The main objective of this production system is to secure uninterrupted and predictable quantities of uniform quality to...

Abscisic acid (ABA) production has emerged a susceptibility factor in plant-pathogen interactions. This work examined the interaction of ABA with nitric oxide (NO) in tomato following challenge with the ABA-synthesizing pathogen, Botrytis cinerea. Trace gas detection using a quantum cascade laser detected NO production within minutes of challenge with B. cinerea whilst photoacoustic laser detec...

Salinity stresses act as inhibitor factors of plant growth. They can change the physiological characteristics and limit the production of crops. Sodium nitroprusside (SNP) is a stable free radical which use as a signalling molecule in plants and participates in various plant’s physiological, biochemical and molecular processes and also in plant’s responses to environmental stresses. We investig...

fusarium wilt caused by fusarium oxysporum f.sp. lycopersici is one of the major obstacles to the production of tomato which causes huge losses in tomato products worldwide. in order to increase the tolerance to this disease, a triple structure containing pr1, chitinase and glucanase genes controlled by 35s promoter was transferred to tomato. eight days after planting on pre-culture medium, exp...

Bohinc T., Žnidarčič D., Trdan S. (2015): Comparison of field efficacy of four natural fungicides and metiram against late blight (Phytophthora infestans [Mont.] de Bary) on tomato – Short Communication. Hort. Sci. (Prague), 42: 215–218. Fungicidal activity of asaronaldehyde, soybean lecithin, garlic extract, salicylic acid, and metiram against late blight on tomato was investigated in a field ...

enzyme-based assay work in combination, and even reproduce precise results at an average 19.4% relative percent difference (RPD). Second, because OP/C causes harmful health effects at high doses, we investigated pesticide concentration of farmers’ market tomatoes compared to supermarket tomatoes. Our results suggested OP/C in three samples: 2 out of 10 farmers’ market tomato samples and 1 out o...
