Abstract

An experiment was conducted to assess the effect of gibberlic acid on germination and seedling vigour index in brinjal species at Department of Vegetable science, College of Horticulture, Venkataramannagudem (A.P.). A total of nine brinjal species (T1: Solanum torvum, T2: Solanum mammosum, T3: Solanum gilo, T4: Solanum indicum, T5: Solanum seaforthianum, T6: Solanum viarum, T7: Solanum aethiopicum, T8: Solanum melongena cv. Pennada Local, T9: Solanum melongena cv. Dommeru Local) were involved in the study. Seeds of these species were soaked in GA3 solution (1000 ppm) for 24 hours in the study. The study revealed that Solanum seaforthianum exhibited the earliest germination. Maximum germination percentage was noticed in Solanum melongena cv. Pennada Local on par with Solanum melongena cv. Dommeru Local. The highest seedling vigour index was observed in Solanum melongena cv. Dommeru Local.

Keywords

Effect, gibberlic acid, germination and seedling vigour index

Conclusion

The present study revealed that priming with GA3 at the rate of 1000 ppm can be effectively used as a pre-germinative treatment to break the dormancy in brinjal species.
