Isolation of Polygalacturonase-Producing Bacterial Strain from Tomatoes (Lycopersicon esculentum Mill.)

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...

Aroma perception of individual volatile compounds in fresh tomatoes (Lycopersicon esculentum, Mill.) as affected by the medium of evaluation

Odor thresholds of volatile compounds in fresh tomato (Lycopersicon esculentum Mill.) were estimated and odor units calculated to determine whether the medium of evaluation affects aroma perception. The ‘ascending method of limits’ was used to determine odor thresholds of cis-3-hexenal, hexanal, trans-2-hexenal, hexanol, cis-3-hexenol, 2-isobutylthiazole, 6-methyl-5-hepten-2-one, geranylacetone...

effect of organic and biological fertilizers on growth and yield of tomatoes (lycopersicon esculentum mill.) and bacterial colonization

introduction: in recent decades, excessive use of chemical fertilizers causes environmental problems such as water resource pollution and decrease in soil fertility. organic matters are excellent sources of plant-available nutrients and their addition to soil could maintain high microbial populations and activities. in crop studies, prabha et al. (2007) reported that there was excellent plant g...

Salt-mediated changes in leaf mesophyll cells of Lycopersicon esculentum Mill. plants Zmiany w komórkach mezofilu liści roślin Lycopersicon esculentum Mill. spowodowane zasoleniem

Five-week-old tomato plants (Lycopersicon esculentum) cv. Perkoz grown in pots containing garden soil in a growth chamber were submitted to 50 or 150 mM NaCl for 1 h, 2 and 5 days. Tomato leaf anatomy generally did not change after short time salinity, except 5-day-treatment with 150 mM NaCl, where changed cell shape (shrunk and deformed) simultaneously with increased volume of intercellular sp...
