Influence of phytohormones on seed germination of Solanum linnaeanum

TL;DR

This study investigates how different phytohormones affect seed germination and seedling growth of Solanum linnaeanum, finding that NAA at 50 mgL-1 significantly enhances germination and growth parameters.

Contribution

It demonstrates the specific effects of NAA, GA3, and SA on germination and seedling development of Solanum linnaeanum, highlighting optimal hormone concentrations for successful germination.

Findings

NAA at 50 mgL-1 yields highest germination rate (77.78%)

NAA at 50 mgL-1 improves germination speed and seedling growth

100 mgL-1 SA results in the longest roots (5.33 cm)

Abstract

The aim of this study was to determine the germination ability and seedling growth of the apple of Sodom by soaking in water, gibberellin (GA3), naphthylacetic acid (NAA), and salicylic acid (SA), separately. The findings showed that NAA at 50 mgL-1 produced superior germination (77.78%), germination speed (1.43 seeds/time interval), hypocotyl length (1.01 cm), hypocotyl diameter (1.13 mm), leaf number (2.66), and root number (17.25), followed by 50 and 100 mgL-1 GA3, particularly in germination percentage. The best root length (5.33 cm) was detected at 100 mgL-1 SA. In contrast, control seeds and water-soaked seeds showed inferior results. The seeds of the apple of Sodom can be germinated successfully as a result of treatment with NAA at 50 mgL-1, followed by GA3 at 50 and 100 mgL-1.
