The embryology of some cleistogamous violets

, : The embryology of some cleistogamous violets. Botanicheskii Zhurnal (St Petersburg) 65(8): 1147-1156

The embryology of Viola mirabilis, V. collina and V. epipsila was analyzed. The characteristics of cleistogamous flowers of the studied species are described and discussed. The partial reduction of the flower organs, the synchronicity of the development of pollen and embryonic sacs and the penetration of pollen tubes from the anther to the stigma were discussed.

Many osteoporotic fractures are probably preventable-by definition, prevention requires identification of those at risk prior to fracture. There is a continuum in fracture risk and a very wide range in risk among individuals. Bone density, previou...
