Variation among 41 Genotypes of Tomato (Lycopersicon esculentumMill.) for Crossability toL. peruvianum(L.) Mill.

Effect of High Temperature and Heat Shock on Tomato (Lycopersicon esculentum Mill.) Genotypes under Controlled Conditions

Tomato (Lycopersicon esculentum MILL.) is usually produced during the winter period in Sudan. In summer due to high temperatures, monthly average temperatures are between 31 to 35°C, a shortage of tomatoes is common. General environmental changes, especially global warming, may have an adverse effect on crop production in Sudan. The objective of this study is (i) to investigate the effect of he...

In vitro flowering and fruiting in tomato (Lycopersicon esculentum Mill.)

In vitro flowering and fruiting were induced in plants regenerated from calli of leaf explants of Lycopersicon esculentum var. Pant 11. MS medium supplemented with 2 mg/l BAP displayed the best response followed by MS with 2 mg/l BAP, 1 mg/ l ABA and 0.5 mg/l IAA. Flower buds were developed both directly from callus and regenerated plantlets from leaf explants under 16 h (39.3 μmol m-2s-1) phot...

characterization of comparative response of fifteen tomato (lycopersicon esculentum mill.) genotypes to nacl stress

a solution culture experiment was conducted to evaluate the salinity tolerance of 15 tomato genotypes in hoagland’s nutrient solution with three levels of nacl (0, 75, and 150 mm). the experiment was conducted in completely randomized design with three replicates. after 30 days of imposition of salt stress, gas exchange parameters including transpiration rate, stomatal conductance, co2 assimila...

A cDNA clone for 5-aminolevulinic acid dehydratase from tomato (Lycopersicon esculentum Mill.).

Characterization of an Ethylene Overproducing Mutant of Tomato (Lycopersicon esculentum Mill. Cultivar VFN8).

Ethylene production rates and tissue ethylene concentrations were determined for the single-gene, Epinastic (Epi) tomato (Lycopersicon esculentum Mill.) mutant, and its parent, cv VFN8. The Epi phenotype was characterized by severe leaf epinasty, thickened stems and petioles, and a compact growth habit. In 4-day-old seedlings, ethylene production was significantly higher in Epi than in VFN8. Et...
