摘要:

对大花美人蕉(Canna generalis Bailey)不同发育时期花瓣、苞片和花萼上气孔的分布情况、气孔密度和气孔指数的变化进行了研究。结果表明，花瓣、苞片和花萼上、下表皮均有气孔分布。花瓣、苞片和花萼上表皮的气孔密度和气孔指数均小于下表皮的。随着花的发育，花瓣、苞片和花萼上的气孔密度和气孔指数一般呈现先上升后下降的变化趋势。

Abstract:

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.
