Abstract

Jamun is raised through seed and requires proper maintenance until graftable stage. Chemical mutagenesis is an important approach for the improvement of crop plants. The efficiency and effectiveness of chemical mutagens are a prerequisite to assess the effective dose for variability. In the present study, five different concentrations (0.1, 0.2, 0.3, 0.4 and 0.5%) of colchicine, ethyl methane sulphonate (EMS) and sodium azide were used to treat jamun seeds to assess morphological, physiological and biochemical analyses. It was noted that with an increase in dosage of colchicine, EMS and sodium azide germination percentage, survivability and growth traits were decreased. Among the different concentrations of chemical mutagens colchicine @ 0.1 per cent were proportional to early seedling emergence, increased germination percentage, improved plant morphological traits and enhanced leaf biochemical compounds in terms of total phenolic and carbohydrate content. The effectiveness of the three chemicals on jamun is ranked as colchicine; EMS; sodium azide. Jamun seeds treated with colchicine 0.1 % can aid for the propagation of superior quality planting material on commercial basis.

Conclusion

As an outcome of the research study out of the chemical mutagens used for seed treatment colchicine @ 0.1 % proved to be the best with significant effects on initiation of seed germination, shoot biomass production, shoot length and diameter, leaf production, root length and diameter and leaf biochemical compounds such as phenols and carbohydrates. For raising superior quality planting material seeds of jamun treated with 0.1 % colchicine can produce healthy and vigorous seedlings on commercial basis.
