Floral dynamic and pollination habit of Fritillaria cirrhosa
Abstract:Objective :To find the sexual reproduction characteristics and improve the seed propagation and new variety breeding of Fritillaria cirrhosa. Method : Flower, anther and pistil development were observed. Pollinating in different development period and bagging were used to measure stigma maturity situation and natural outcrossing rate. Results and Conclusion : It took 12 days from floral bud emergency to finished flowering. It was observed that anther opened in longitudinal direction and pollen was ejected for 2-4 days continuously. Pistil matured earlier,and chapiter could be fertilized from middle bud stage the third day after flowering, but the most suitable time was 2-3 day after the corolla opening. The natural outcrossing rate was 81.9%. F. cirrhosa is a typical xenial plant.
