Abstract:

To study different concentrations of NAA, GA3, IBA and 6-BA influence on basil seed germination and seedling growth, With different concentrations of NAA, GA3, IBA, and 6-BA pretreatment 24 h, after soaking the seed germination rate and the seedlings of different indicators to study plant growth regulators soaking basil seed germination and seedling growth. The results showed that after 100 mg/L GA3 soaking, the seed germination rate increased by 26.6%, total chlorophyll content increased 30%, specific activity of peroxidase increased 70%. After 25 mg/L IBA soaking, the seed germination rate increased 26.6%, total chlorophyll content increased 25%, specific activity of peroxidase increased 60%. Each indicator increased significantly compared with the control. So we could get the conclusion that 100 mg/L GA3 and 25 mg/L IBA soaking could do great help to basil’s seed germination and seedling growth, which could be used in bulk production.
