Effect of Genotype and Explant Type on in Vitro Shoot Regeneration of Tomato (lycopersicon Esculentum Mill.)
In order to select the best tomato cultivar for Agrobacterium mediated gene transformation studies, In vitro regeneration frequency of hypocotyls, leaf disc and shoot tip of five tomato cultivars (Lycopersicon esculentum) was investigated on a regeneration medium supplemented with 1 mg/l zeatin and 0.1 mg/l indole-3-acetic acid. Significant differences in regeneration capacity between genotypes...
متن کاملIn 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...
متن کاملMatthiola incana Micropropagation Using Shoot Tips and Callus Induction Derived from Lamina Explants and Rooting Capacity from Callus
Tissue culture is an attractive alternative for plant propagation. Micropropagation is a technique to ensure a constant and uniform source of ornamental plants. Matthiola incana is an important ornamental species mainly cultivate by seed. Matthiola incana seeds were germinated on solid MS medium without plant growth regulators. Shoot proliferation and root formation are possible using kinetin (...
متن کاملCallus Induction and Shoot Regeneration from Epicotyl Explants of Ethnomedicinally Important Caesalpinia bonduc (L.) Roxb
An efficient plant regeneration method was established for Caesalpinia bonduc (L.) Roxb. by culturingimmature epicotyl explants. Morphogenic calli were initiated from 96% of epicotyl explants on MS mediumsupplemented with BA (6-benzylaminopurine) 4.0 mg/l and NAA (Naphthalene acetic acid) 1.0 mg/l. The calliformed were excised and subcultured on MS medium fortified with 1 mg/l...
متن کاملEffect 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...
