Семенная продуктивность лука стебельчатого – Allium stipitatum (Alliaceae) в услвиях культуры (Таджикистан)

Abstract

This article presents the results of studying the plant introduction and the possibility of cultivation of Persian shallot – Allium stipitatum Regel. This plant is popularly used in pickled and salt form for the preparation of various salads, because of which it is classified as an endangered species and is listed in the Red Data Book of the Republic of Tajikistan. Studies on the seed productivity of domesticated Persian shallot were carried out in 2017- 2019 on the territory of experimental plots of the National Republican Center of the Genetic Resources of the Tajik Academy of Agricultural Sciences (Gissar Valley), which is located in the northern part of Rudaki district at an altitude of 730 m above sea level. It was established that the average number of fruits is 250 ± 15.7 pcs; the number of fruit set is 210 pcs; the total number of seeds is 809 pcs per fruit. When compared with the natural growing conditions (Gajne area), it turned out that the seed productivity of Persian shallot under natural conditions is averagely 16.7% - 24.5% higher than in the Rudaki district (Gissar Valley). As a result of the studies, it was found that it is necessary to choose areas with natural protection from sunlight (protective forest belts or stool beds) to create more favorable conditions in the first years of adaptation of Persian shallot in the Rudaki district.
