Abstract:

Effect of different pre-sowing treatments on germination of P. guajava seeds revealed that all the treatments had play a significant role on seed germination, earlier germination, seedling girth, number of leaves, height of the seedling, root length and vigour index of the seedling. The highest percentage of germination was recorded in GA3 @ 1000 ppm for 24 hours. Germination start in 16.15 days after sowing and completed in 30.33 days. The minimum duration 16.15 days for germination when the sowing of seeds treated with GA3 @ 1000 ppm for 24 hours. Height 32.50 cm and girth of seedling 2.42 mm varied significantly with different sowing treatments. Number of leaves per seedling also influenced by different sowing treatments and maximum (20.00) number of leaves per seedling was recorded in seed soaked with GA3 @ 1000 ppm for 24 hours. Different sowing treatment greatly influenced the seedling survival in nursery. Maximum (85.57%) seedling survival was obtained, when seeds soaked with GA3 @ 1000 ppm for 24 hours. The transplanting success ranged between 28.42 and 97.32 per cent and highest transplanting success was noted in seed soaked with GA3 @ 1000 ppm for 24 hours.
