Flowering biology and dynamics of accumulation of sugars in Eremurus spectabilis M.Bieb.
Summary
The article is dedicated to the study of flowering biology and the dynamics of sugar accumulation in the plant Eremurus spectabilis. In the course of research, it was established that the growth of E.spectabilis during the vegetation period is on average 52-58 cm. The flowering phase begins in May. The plant has a basipetal inflorescence. The number of flowers that open per day depends on the density of the inflorescence. During the study of the dynamics of the accumulation of sugars during the day in E.spectabilis plants, the amount of sugars in the leaves of the plant was recorded after 9, 10, 11, 13, 16 and 20 hours. As a result of the study, an increase in the amount of glucose in samples taken after 9, 10, 16 and 20 hours was noted. It was established that in the samples taken at 1200 hours, the accumulation of glucose was 2 times less than in the samples taken at 900 hours. A small accumulation of fructose was observed, and this amount remained at a low level during the day. During 9, 10, 16 and 20 hours, high accumulation of sucrose was not observed. The highest accumulation of sucrose was detected at 1200 and 1400 hours.
