Abstract
Actuality. Today, landscape designers are required to introduce a new assortment of plants into culture, in particular annual ornamental crops.
The purpose of the study is to investigate the manifestation and relationships of morphometric indicators and varietal characteristics of plants of the genus Tagetes L.
Materials and methods. The research material was 10 varieties of marigolds: Orange Prince, Sugar and Spices, Moonlight, Hawaii, Red Brocade, Cupid Lemon, Bolero, Mandarin, Marietta and Manjestik. The following research methods were used: field – determination of morphometric indicators and varietal characteristics of plants and the duration of the flowering phase of marigolds; laboratory – determination of varietal characteristics of the plant, leaves and inflorescences; statistical – identification of relationships between the studied indicators.
Research results. The longest period of “beginning-mass flowering” was established in the varieties Red Brocade and Marietta (over 30 days). Medium-sized varieties were distinguished: Orange Prince, Moonlight, Hawaii and Manjestik. The Manjestik variety was noted for the number of inflorescences on the plant (97 pcs.). A semi-spreading plant habit and moderate branching of the plant were revealed in most varieties. The Hawaii variety was distinguished for leaf size. The largest baskets were noted in the varieties Orange Prince, Moonlight, Hawaii, Sugar and Spices. The type of flowers in the inflorescence of marigolds was established: tubular-reed, tubular and reed. The Marietta and Manjestik varieties were distinguished for the presence of a two-color basket. A strong relationship was established between the indicators: diameter and length of the basket with a peduncle, the indicator of plant height at the beginning of flowering and during full flowering; correlations of medium strength between the indicators: length of the basket with a peduncle and length of the peduncle; length and width of the leaf; as well as the inverse relationship between the number of inflorescences on the plant and the length and diameter of the basket.
Conclusions. The duration of the period “beginning-mass flowering” in varieties of marigolds of the genus Tagetes L. was established. Morphometric indicators of the plant in the flowering phase and the manifestation of varietal characteristics of the plant, leaf and inflorescences in varieties of marigolds were determined. Relationships between the studied indicators were noted.
