The viability and germination capacity of verbena bonariensis and verbena rigida seeds

, : The viability and germination capacity of verbena bonariensis and verbena rigida seeds. Seed Science & Technology 8(4): 615-624

Seed viability was determined by the standard tetrazolium [TTC] producure and a modified tetrazolium method using a 0.3% INT [iodonitrotetrazolium] instead of a 1% TTC solution. This procedure demonstrated viability of about 87-95% although germination tests showed it to be low and inconsistent because of dormancy. Periodical germination tests indicated that loss of dormancy begins at 2 mo. after harvest. The germination capacity determined in this way during the 6 mo. of the experiment always fluctuated and was far beneath the real level. A temperature regime of C was optimal for germination of V. bonariensis, but for V. rigida C and C were both optimal. In most cases pre-chilling at C for 5-7 days, proved effective in overcoming dormancy in V. bonariensis. But in V. rigida the germination capacity remained far beneath maximu viability.
