Biologia wzrostu i rozwoju dwu odmian dyptamu jesionolistnego (Dictamnus albus L. cv. Albiflores i cv. Rosa Purple) oraz budowa anatomiczno-morfologiczna struktur wydzielniczych, skład olejku eterycznego i analiza ekstraktu

Summary
The paper presents the biology of growth and development of two varieties of dittany (Dictamnus albus L. cv. Albiflores and cv. Rosa Purple). The present study include biometric measurements of morphological characteristics, including the flowering and pollination dynamics and efficiency of pollen. Measurements of the amount of shoots, stems of length and a width and length of the leaves. Set the number of flowering shoots, as well as the number of flowers on the shoot and the number of flowers per plant, given the dimensions of the grains of pollen, nectar and mass concentrations of sugar and honey yield. The work contains a photo plots of arable dittany. Anatomical-morphological study of individual organs are shown in the photographs. The research was the structure of the secretory glands, Italian, ducts and conduits oils. Essential oil content was determined using three methods, and qualitative composition by GC/MS and SPME/GC/MS. Grown in the experimental plot plants reached an average height of 91 cm and 95 cm Albiflores variety Rosa Purple variety respectively. Flowering plants usually began in the third decade of May and continued until mid-June. The life of flowers is from 5 to 7 days. Flowers Albiflores varieties were characterized by a greater abundance of flowering and pollen higher efficiency and greater mass secreted nectar and honey. Analysis of the content and composition of the essential oil in the flowers cv. Albiflores content was 0.76%, while in the cv. Rosa Purple 0.60%, respectively 0.22% and 0.30% – herbs, and 0.10% and 0.02% roots. The main components of the essential oil obtained from the herb and roots were: limonene, myrcene, terpinolene, α-terpineol and germacrene D.
