Abstract

It has described structure of the pericarp of 6 Ferula species fruits in natural habitat conditions: Nuratau range and Kyzylkum Desert. Differences in the location and structure of the secretory conceptacles have been discovered due to their biomes and habitat conditions. Secretory tubules of mature fruit pericarp (Scorodosma subgenus) F. foetida obliterated. In the pericarp (Macrorrhiza section) of F. varia fruit, there are two types of secretory structures: dorsal and commissural. In the fruit pericarp of (Xeronarthex section) F. kyzylkumica, F. helenae, F. dshizakensis and F. angreni species, there are three types: dorsal, commissural and costal, which increase their drought resistance and reflect a higher evolutionary level of taxa [1].

Highlights

  • Apiaceae Lindley family spreads across the globe

  • Mericarp differ in shape: round-oval or elliptical, flat-compressed (F. foetida, F. varia), oblong-oval (F. kyzylkumiсa, F. helenae, F. angreni), obovate (F. dshizakensis)

  • It has been revealed that a various localizations of secretory structures in the pericarp of the fruit of Ferula species: secretory tubules of F. foetida pericarp are obliterated, which is associated with monocarp

Summary

Introduction

Apiaceae Lindley family spreads across the globe. A center of diversity of the family is considered Middle Asia. Many types of umbellate are of great importance in the composition of vegetation cover, as dominants of mountainous and arid regions [2]. Ferula species figure prominently in today’s complex investigation of umbellate. The study of the secretory system of different organs and characteristics of terpene-containing conceptacles are important to determine the localization of some biologically active compounds [3]. Features of the pericarp histological organization of fruit species of Umbelliferae family are used on solution of taxonomical and phylogenic problems.
