Seed histochemistry of Melia azedarach l.

Mydeen Fathima Begam K., Manimekalai V.*


Anatomical investigation of cotyledons of Melia azedarach L. shows the presence of parenchymatous cells along with large sized secretary cells. Secretary cells could be distinguished by specific histochemical stains like Sudan III and Iodine Potassium Iodide (I2KI). Cotyledons are also filled with starch and oil bodies. The present study on secretary cells has paved way towards understanding the distribution of various chemicals in particular terpenoids in the cotyledons. These methods, in combination with various microscopic imaging techniques, can be utilized in the study of essential oil secretion in plants.
