Abstract:
The present study was carried out to investigate the effect of pre-sowing treatments on seedling growth of guava (Psidium guajava L.).The experiment comprised of 13 different pre-sowing treatments with three replications. The results from the study revealed that pre-sowing treatments significantly influenced seedling growth of guava as among different pre-sowing treatments, Scraping of seed coat with sand paper + seeds soaked in GA₃ 200ppm for 24 hours (T₅) performed best in terms of height of seedling (4.59cm), shoot length (6.75cm), root length (5.85cm), root: shoot ratio (0.87), number of leaves per seedling (12.40), leaf area of seedling (3.83cm²) and total chlorophyll content (29.85 SPAD unit). Whereas, Girth of seedling was found maximum (1.34mm) in quick dip soaking in 30 sulphuric acid T_8(i).
