Embryo - Pollen Biology
The suspensor cells of young embryos of Tropaeolum majus show that the activity of acid phosphatase increases from micropylar to chalazal pole. The concentration of 6-PGDH and G6PDH is high in very young embryos of Lilium regale By globular stage the activity decreases considerably. Implicit in these results is the fact that different regions of embryo would provide some explanation of different embryogenic processes.
Also, a marker system can be established for identifying differentiating areas in the developing embryos. What is needed is the uniformity of the enzyme system being explored in different climatic conditions which may affect metabolic processes thus influencing the sexual cycle. This may lead to detection of variations in developmental sequences or abnormalities so often reported in the literature.
