Abstract: The present investigation was carried out to assess the effect of titanium dioxide and zinc oxide nanoparticles on germination and vigour in tomato (Solanum lycopersicumI L.) seeds in the Seed Testing Laboratory of the Department of Genetics and Plant Breeding, Sam Higginbottom University of Agriculture, Technology & Sciences, Allahabad during 2017-18. These five varieties (Kashi Amarit (DVRT-1), Kashi Anupame (DVRT-2), Kashi Adarsh, Kashi Vishesh (H-86), Kashi Aman) are conducted in CRBD having four replications treated with distilled water @ 100ml., control, Nano priming - TiO2 (25 mg), TiO2 (50 mg), TiO2 (75 mg), TiO2 (100mg), TiO2 (150 mg), TiO2 (200 mg), ZnO (25mg), ZnO (50mg), ZnO (75 mg), ZnO (100mg), ZnO (150mg), ZnO(200 mg) at a period interval of 6 hours respectively. In all the five varieties TiO2 25 mg and ZnO 25 mg was found as best among all the concentrations for seed quality parameters and vigour parameters viz. in germination percentage Kashi Aman found superior (83.56 %) at TiO2 25 mg while Kashi Amarit (90.00 %) at ZnO 25 mg. In speed of germination Kashi Anupame found superior (27.50) at TiO2 25 mg while Kashi Amarit found superior (28.68) at ZnO 25 mg. In mean germination time Kashi Amarit found superior (43.87) at TiO2 25 mg and (43.31) at ZnO 25 mg. In root length Kashi Amarit found superior (10.04 cm) at TiO2 25 mg and (8.77 cm) at ZnO 25 mg. In shoot length Kashi Amarit found superior (5.56 cm) at TiO2 25 mg while Kashi Aman (5.403 cm) at ZnO 25 mg. In seedling length Kashi Amarit found superior (15.43 cm) at TiO2 25 mg and (15.03 cm) at ZnO 25 mg. In seedling fresh weight Kashi Amarit found superior (2.03 g) at TiO2 25 mg and Kashi Adarsh (2.05 g) at ZnO 25 mg. In seedling dry weight Kashi Anupame found superior (0.027 mg) at TiO2 25 mg and (0.027mg) at ZnO 25 mg. In vigour index –I Kashi Amarit found superior (1062.50) at Tio2 25 mg and (1087.50) at ZnO 25 mg. In vigour index –II Kashi Adarsh found superior (9.74) at TiO2 25 mg and (9.59) at ZnO 25 mg. In electrical conductivity of seed leachate Kashi Vishesh found superior (68.66) at TiO2 25 mg and Kashi Adarsh (69.13) at ZnO 25 mg. In seed metabolic efficiency Kashi Aman found superior (0.115) at TiO2 25 mg and Kashi Amarit (0.115) at ZnO 25 mg. In field emergence index Kashi Vishesh found superior (94.40) at TiO2 25 mg and (94.12) at ZnO 25 mg. The variance revealed considerable variability among the genotypes for all the characters. Titanium Dioxide (TiO2) and Zinc Oxide (ZnO) nanoparticles at 25 mg concentration is beneficial to improve the seed quality and vigour parameters of tomato seeds.
