Taxon: tomato ✕

Taxon groups are the verbatim names found in the abstracts (case-insensitive), not normalised: maize, corn and Zea mays are separate groups here. The Organism view merges them through NCBI Taxonomy.

Title

Allelopathic effect of aqueous extract from cucumber (Cucumis sativus L.) aboveground part on tomato (Lycopersicon esculentum Mill)

Jian Liu Zhongguo shengtai nongye xuebao 2009

Other claims from this paper (15)

Observation Cucumber aboveground extract contained several chemical groups but not tannins.
Intervention effect The extract inhibited tomato seed respiration rate and α-amylase activity.
Intervention effect The extract inhibited tomato germination rate and germination index increasingly with concentration.
Intervention effect Extract watering increased reactive oxygen species in tomato seedling leaves.
Intervention effect Extract watering increased glutathione, ascorbic acid and malondialdehyde in tomato seedling leaves.
Intervention effect Extract watering increased plasma membrane permeability in tomato seedling leaves.
Intervention effect Extract watering decreased catalase and peroxidase activity.
Intervention effect SOD and APX activity first increased and then decreased as extract concentration rose.
Intervention effect Transpiration rate and dry seedling weight decreased.
Intervention effect Intercellular carbon dioxide content increased.
Intervention effect Initial fluorescence rose with extract concentration.
Intervention effect Maximum fluorescence and two PSII efficiency measures decreased.
Intervention effect Actual PSII efficiency, photochemical quenching and electron transport decreased.
Intervention effect Photochemical rate decreased.
Intervention effect Non-photochemical quenching initially increased and then decreased.

Title

The Influence of Root Knot Nematode, Meloidog Yne Javanica, On Photosynthesis and On Nutrient Demand By Roots of Tomato Plants

H.R. Wallace Nematologica 1974. doi:10.1163/187529274x00546

Other claims from this paper (7)

Intervention effect At 250 larvae, tomato photosynthesis was lower than in uninfected plants.
Observation Photosynthesis rose and then fell markedly as inoculum increased.
Observation Root 14C-glucose incorporation declined only at 2,000 nematodes per plant.
Intervention effect Root 14CO2 incorporation declined at 250 nematodes versus uninfected plants.
Observation Inoculation with 2,000 nematodes caused no further decline in 14CO2 incorporation.
Observation The results did not support root metabolic sinks as a major driver of shoot growth.
Observation The photosynthesis data suggested inhibited upward water and nutrient transport may be more important.

Title

Effects of BTH on TYLCV resistance,photosynthetic characteristics and related defense enzymes of tomato seedlings

Yu Li; Guo ShiRong; Yan Jun; et al. Nanjing Nongye Daxue xuebao 2012

Other claims from this paper (6)

Intervention effect At 0.50 mmol·L-1, BTH gave the best induced resistance, reaching 42.7% efficiency.
Intervention effect BTH significantly increased net photosynthetic rate and stomatal conductance.
Intervention effect BTH slowed the decline in net photosynthetic rate and stomatal conductance after TYLCV inoculation.
Intervention effect BTH induction increased tomato peroxidase, polyphenol oxidase and phenylalanine ammonia lyase activity.
Intervention effect TYLCV inoculation increased tomato peroxidase, polyphenol oxidase and phenylalanine ammonia lyase activity.
Intervention effect Combined BTH induction and TYLCV inoculation increased the defence enzymes faster than BTH alone.
