Abstract

The aim of research was to reveal the morphology-anatomical features of leaf blade structure of the different age conditions of Murraya exotica.

The study of morphology-anatomical signs of plants of the different age conditions is important at determination of effectiveness of the variety introduction in new ecological conditions and favors the spread of assortment of resistant plants for the use in greenery planting. Most tropical and subtropical plants have not been studied yet, although they are a source of greenery planting and useful properties.

The object of research is Murraya exotica L. from Rutaceae Lindl family.

Morphology-anatomical, comparative and ontogenetic methods were used in this research.

According to the results of research, the differences of leaf blade of juvenile and adult plants were established in both morphological and anatomical structure. Leaves in juvenile plants of the studied variety differ by form and sizes. Micromorphological studies revealed that leaves of the studied variety are anisostomatic in all age conditions, the number of stomas changes with leaf age. At ontogenesis the changes take place in the anatomical structure of leaf blade (epidermis and parenchyma thickness).

Conclusions. According to the results of researches, it was established, that   Murraya exotica plants in juvenile condition differ from adult ones by leaf form and sizes. The number of stomas in sight, leaf and epidermis thickness at ontogenesis grows from the sprout stage to generative plants. The thickness of columnar parenchyma considerably grows. The gardening coefficient grows in correspondence with age that indicates the more resistance of generative plants to cultivation conditions
