Y. W. Chen, S. S. Chen
1. Through 3 years of study and observation on seed multiplying for black salsify, it was found that September-October are most suitable planting period for seed producing.
2. According to the black salsify, which needs low temperature to promote blooms, therefore, late planting should be avoided.
3. The quantity of seed production for per ha. There were (1) 60kg if the rate of blooming above 90% and rate of pollination is 50%. (2) 40 kg if 60% of blooming rate and 50% of pollination rate. (3) 25 kg if 40% of blooming rate and 50% of pollination rate. It was showed in this experiment.
4. There are no problems to produce the seed of black salsify in Taiwan, but how to make it increase the blooming and pollination rates, and obtain the uniformity of blooming period are important and expect to study continuously.
