Preliminary Study on Effects of Temperature and Pollination on Flower Opening and Closing of Taraxacum ohwianum
The inflorescence of Taraxacum ohwianum Kitam.opened and closed repeatedly for 3 to 4 days,then permanently closed.Pollination or unpollination has little impact on floral longevity;but pollination accelerated flower closure thus reduced the show time.Temperature and pollination can affect flower opening and closing.The capitula opened at about 20 ℃ and closed at 15 ℃.Florets quantity and weather condition would affect the insect species and quantity,so further affect the close process.Pollination process can greatly reduce the show time (about 4 h/d).The more pollinators and the higher temperature is,the faster the closure process of flowers.
