摘要
菊苣(Cichorium Intybus L.)开花及种子形成规律的研究表明:在太原地区,菊苣6月上旬开始开花,三周之后即7月初达盛花期。种子在授粉后20天即发育成熟,此时,种子发芽率及千粒重均达到最高。最佳种子收获期应在盛花期后20～30天,此时种子呈深褐色,水分含量为25％左右。
Flowering and seed development studies showed that the flowering of chicory started in early June and peak flowring in early July. Seed maturity occured 20 days affer pollination When maximum seed germination and maximum thonsand seed dry weight were reached. The optimum time to harvest seeds was from 20 to 30 days after peak flowering, When the seeds were deep brown and seed moisture was about 25%.
