Abstract

The article deals with the seasonal rhythm of development of the bulbaceous acrosympodially accreting polycarpic Allium trautvetterianum Regel (the subgenus Melanocrommyum) when growing in the Kulyab Botanical Garden of the Khatlon Scientific Center, Academy of Sciences of Tajikistan in 2010-2015. Duration of vegetation and phenological phases is described. The species is characterized on the phenorhytmotype as a shortgrowing ephemeroid. Influence of weather conditions on duration of phenological pahses is shown. It is established that the rhythm of development completely corresponds to the eastern variant of Mediterranean climate.

Highlights

Seasonal rhythm of development of plants is a representation of their life cycle which is shown in repetitive phenophases
Allium trautvetterianum is an endemic plant of the south-western Pamir-Alay, it grows in the semisavanna belt with domination of Prangos pobularia, Organum tyttanthum, Salvia sclarea, Hypericum scabrum, Taeniatherum asperum, Poa bulbosa, and Carex pachystylis, in the shibliak belt with domination of Pistacia vera, Crataegus pontica, and Amygdalus bucharica, and occurs at the exposure of vaiegated at an altitude of 700–1700 m above sea level
The species has been cultivated in the Kulyab Botanical Garden since 1999 г

Summary

Introduction

Seasonal rhythm of development of plants is a representation of their life cycle which is shown in repetitive phenophases. Study of phenophases is necessary for understanding for plant community functioning [1]. The change in time and duration of the passage of phenophases to adjust to new conditions is one of the indicators of plant adaptation to changing environmental conditions. In the context of climate change, the importance of phenological study is currently increasing. According to current data the genus Allium L. numbers about 900 species. Onions are widespread in the northern hemisphere and represent one of the largestgenera of the world flora [1]. The subgenus Melanocrommyum contains 170 species, the range of which is mainly restricted to the region of Ancient Meditarrenean [2]. Thirty one species of this subgenus grow in Tajikistan
