|Germination||Seed will benefit from a short cold moist stratification (30-60 days) to increase speed, uniformity and % of germination. Germination will improve with alternating temperatures of approx. 8 hours @ 86 deg. F and 16 hours @ 68 deg. Many growers use a fungicide durring stratification. Other sterilization methods you can use include a 12 hour hydrogen-peroxide soak; surface sterilization with a 1:10 bleach:water mix, soaking the seed for 8 minutes then thoroughly washing off the bleach with warm water; a short diluted iodine soak. |
1. Scarification: Soak in water, let stand in water for 24 hours
2. Stratification: cold stratify for 30-60 days
3. Germination: sow seed 1/4 deep, keep moist, mulch the seed bed, cover seedbed with some shade, can be sown outdoors in the fall for spring germination.
Stratified syringa seeds normally germinates in 14-60 days. Normally will only germinate with light, GA-3 may promote germination - even in the dark.
