Prolonged exposure to atmospheric nitrogen dioxide increases fruit yield of tomato plants

Influences of irrigation interval,nitrogen fertilization and plant spacing on tomato fruit yield and quality

Personal exposure of children to nitrogen dioxide.

Combined exposure to ozone and nitrogen dioxide.

The combined effects of ozone and nitrogen dioxide were assessed in an in vitro test system utilizing human red cells. In general, these two pollutants had additive effects on the parameters measured which included osmotic fragility, acetylcholinesterase activity, lipid peroxidation, reduced glutathione and methemoglobin levels. However, at lower pollutant doses a synergistic increase in lipid ...

Tomato Genotype in Relation to Nitrogen Utilization and Yield

Twelve different tomato (Lycopersicum esculentum Mill.) genotypes were grown in a controlled greenhouse to determine the influence of genotype variation on the efficiency of nitrogen utilization and fruit yield. The results showed that the variation of genotype in tomatoes influences the utilization and assimilation of foliar NO3. The genotypes that proved highly efficient in this utilization w...

Root-synthesized cytokinins improve shoot growth and fruit yield in salinized tomato (Solanum lycopersicum L.) plants

Salinity limits crop productivity, in part by decreasing shoot concentrations of the growth-promoting and senescence-delaying hormones cytokinins. Since constitutive cytokinin overproduction may have pleiotropic effects on plant development, two approaches assessed whether specific root-localized transgenic IPT (a key enzyme for cytokinin biosynthesis) gene expression could substantially improv...
