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...
متن کاملProteomic analysis of tomato (Lycopersicon esculentum) pollen.
In flowering plants, pollen grains are produced in the anther and released to the external environment with the primary function of delivering sperm cells to the female gametophyte. This study was conducted to identify proteins in tomato pollen and to analyse their roles in relation to pollen function. Tomato is an important crop which is grown worldwide and is an excellent experimental system....
متن کاملSimulation of dry matter accumulation, partitioning and yield prediction in processing tomato (Lycopersicon esculentum Mill.)
Simulation of dry matter accumulation and the distribution of crop growth is an important means of predicting yield. In this study, a variety of cultivars of the processing tomato (Lycopersicon esculentum Mill.), sowing dates and densities were tested. By analyzing the quantitative relationships between growth and physiological development time (PDT) based on a knowledge model, dry matter parti...
متن کاملEffect 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 کاملChanges in the Photosynthetic Responses and Biochemical Constituents of Tomato (Lycopersicon esculentum Mill.) Under Zinc Stress
High heavy metal availability induces an ion stress in which is concerned with the synthesis of auxin-indole plants clearly distinct from salt stress. Heavy metals do acetic acid and transformation of carbohydrates [7]. There not affect plant growth by a significant decrease of the are 59 kinds of zinc containing enzymes representing osmotic potential of the substrate but by their own almost al...
