The halopriming of seeds improves the germination, growth, physiological and phytochemical attributes of tomato under saline conditions

The low seed germination response and seedling growth of crops to salinity is common problem in Pakistan. To overcome this problem,seed priming used as an economic effective approach. Present study was conducted evaluate the effects halopriming ofseeds on germination, yield tomato under saline conditions. seeds variety ‘Raja’ were primed with 0, 50mM 100mM NH4NO3, KNO3, (NH4)2SO4 solutions for 12 24 hours. irrigated separately tapwater, water, Hoagland solution water. results indicated that NH4NO3and significantly increased percentage (GP) from 58% (unprimed) 95% (primed) while decreased meangermination time (MGT) 7.44 days 4.6 (primed). A significant increase observed height plant, leafarea, number leaves, shoot root biomass, fruits per etc. plants undersaline Similarly, NH4NO3 KNO3 also enhanced chlorophyll pigments, lycopene contents, totalsoluble sugars, total proteins, phenolic contents flavonoids saltstress. Furthermore, proline NaCl compared other treatments andcontrol. In conclusion, are more agents than positively affected plantheight, physiological biochemical attributes non-saline supplement Hoaglandsolution salt stress further improves morphological, tomato.
