Effect of physical and chemical mutagens on seed germination and survival of seedling in Lycopersicon esculentum Mill
Description
Dry and healthy seeds of Lycopersicon esculentum Mill. var. Co-2 were irradiated with gamma rays at 10 KR, 20 KR, 30 KR, 40 KR and 50 KR. The percentage of seed germination was directly proportional to the dose given. The survival percentage decreased with higher doses. Concentration of EMS and NMU applied, ranged from 10 mM to 50 mM and 1 mM to 5 mM, respectively. The duration of soaking of seed was 4 hours in distilled water and 4 hours in mutagenic agents. In treated seeds, the percentage of germination and survival of seedlings decreased with an increase in concentration of these chemical mutagens. These observations are discussed in detail.
