Abstract

The dry seeds of Albizia lebbeck were treated with 10, 30, 50, 70 and 90 kR of gamma irradiation from a CO60 source, then seeds were either sown directly or subjected to pre-sowing treatment (immersed in boiled water for 2 min. followed by soaking in cold water for 24 h.). Pre-sowing treated seeds showed a higher germination, better height and dry weight compared to those, were sown directly.

As the dose rate increases, there was a decreasing trend in all above parameters. Highest CV (15.06%) was for RVI and lowest CV (7.17%) for plant height was observed. Dose of gamma irradiation had a significant effect on shoot length (plant height), SDW and RDW, while hot water treatment had a significant effect on SVI, RVI. Both dose and hot water pre-sowing treatment significantly influenced RVI and SVI. The LD50 values for different parameters are also worked out. It appears that irradiating seeds of Albizia lebbeck at 40 to 60 kR would result in maximum recovery of mutants.
