Dynamics of gladiolus leaves growth
Abstract: Gladiolus L. are beautifully flowering perennials that do not overwinter in the open ground in the conditions of central Russia. Its varieties are characterized by a huge variety in the height of the peduncle, the color scheme and the corrugation degree of the flowers. The disadvantage of this crop is the complexity of the annual digging and planting of corms. The purpose of the article is to study the growth dynamics of real gladiolus leaves in the open ground. Leaf height measurements were carried out after 15 days in the process of growing plants on ridges. The objects of the study were 9 varieties: 'Aurora', 'Granatovyj braslet', 'Grad Kitezh', 'Devichi tajny', 'Dolgozhdannyj debyut', 'Majya Plisetskaya', 'Tanyusha', 'Shapka Monomaha', 'Noon Moon'. The study showed that the most intensive growth of gladiolus leaves occurred after the emergence of sprouts. On the 20th day after planting, the plants reached about 1/3 of their final height, and on the 35th day – 50%, after 2 months – the height was almost 90%. Most varieties were characterized by the greatest increase in the first accounting period, in the future its value decreased, reaching a minimum in the last accounting period. In the process of growth, the taller varieties remained tall, the shorter ones remained stunted. At each date of the study, 'Devichi tajny' had the highest height, 'Grad Kitezh' had the lowest height. The obtained data can be used in the cultivation of gladioli in nurseries and landscaping location.
