| Abstract | ||||
| Present study was conducted at Laboratory conditions of Seed Technology Research Department at Sakha, Field Crops Research Institute, ARC, Giza during 2019 season. The purpose of the research was to study the effect of priming duration (6, 8 and 10 hours) and seed priming (hydro-priming, 50, 75 and 100 mgL-1 of salicylic acid, 1, 2 and 3 % of KH2PO4 and 1, 2 and 3 % of ZnSO4 ) and dry seed on improving germination of seed and seedling vigor of white hybrid teosinte. Results indicated that six hours priming duration gave the highest germination percentage, seedling vigor, speed germination index and seedling vigor index. Seed treatment with 2 % of KH2PO4 was the best treatment followed by salicylic acid 100 mgL-1 and 3 % of ZnSO4 recorded the highest seed germination%, seedling vigor, speed germination index and seedling vigor index. Hydro-priming produced the higher values of most traits such as plumule and radical length, seedling dry weight, speed germination index and the lowest in electrical conductivity. The interaction effect was significantly where six hours duration and seed priming with 2% KH2PO4, 3% of ZnSO4 and 100 mgL-1 of salicylic acid were the highest germination% and seedling vigor and insignificant with hydro-priming. The lowest values of EC produced by 6 hours with 2% of KH2PO4 followed by 3% of ZnSO4 and hydro-priming. We can conclude that hydro-priming for 6 hours before sowing of white hybrid teosinte increased germinationpercentage to reach 80% compared to dry seed, also seedling vigor characters. | ||||
