Dynamic Change of Stomatal Density and Stomatal Index on the Flower during Canna generalis Bailey Development
大花美人蕉花发育过程中气孔密度和气孔指数的动态变化

The changes in stomatal distribution, density and stomatal index of Canna generalis Bailey flower at different development stages were studied. The results showed that stomata distributed in upper and lower epidermis of petal, bract and calyx. Stomatal density and stomatal index on upper epidermis of petal, bract and calyx were smaller than those on lower surface. With the development of flower, the stomatal density and stomatal index on the petal, bract and calyx increased firstly and then decreased.
