Corolla Color

Lonicera japonica Thunb., known as Japanese honeysuckle or golden-and-silver honeysuckle, belongs to the honeysuckle family and is native to eastern Asia, including China, Japan, and Korea. Microscopy, spectrophotometry, colorimetry, and the Royal Horticulture Society of Colorimetric Card (RHSCC) were used to compare and analyze the pigment distribution, content, and color variations in the Yujin 2 and Damaohua cultivars at different developmental stages. There were notable differences in the corolla color and the cross-section color between different developmental stages and different varieties. The lightness (L*), redness (a*), and yellowness (b*) values were calculated for each period for the two cultivars to observe variation trends. The chlorophyll content in the corollas of both cultivars showed declining trends with different rates. The chlorophyll content decreased rapidly from the young period to the two white period, and changed gradually from the two white period to the golden period. Moreover, the carotenoid content declined slightly from the young period to the silver period and rose sharply during the golden period. The ratio of these two pigment contents increased dramatically during the golden period: by 11.51 and 6.53 times in ‘Yujin 2’ and ‘Damaohua’, respectively. There were significant differences in corolla color, cross-section color, and the content of three pigments between the two varieties of honeysuckle. distribution and variation of pigments were the key factors affecting the flower color of honeysuckle. This study provides a basis for the identification and breeding of honeysuckle varieties and lays a foundation for further studies on the function and molecular mechanisms of pigments.

Japanese honeysuckle (Lonicera japonicaThunb. # LONJA) vines can smother young trees, presenting problems in nursery, parkland, and woodlot management. The tardy-deciduous nature of honeysuckle provides an application window for its selective control with glyphosate [N-(phosphonomethyl)-glycine] or dichlorprop [(±)-2-(2,4-dichlorophenoxy)propanoic acid] plus 2,4-D [2,4-dichlorophenoxy)acetic acid] immediately after fall defoliation of hardwood species. Glyphosate at 1.5% v/v (5.4 g ae/L) applied in December killed mature, woody honeysuckle vines and eliminated most regrowth from basal and subterranean buds 28 months after treatment. Dichlorprop plus 2,4-D at 1.5% v/v (3.6 g ae/L of each herbicide), when applied shortly after the first freezing temperatures in October, was as effective as glyphosate but was less effective when applied in December. Tuliptree (Liriodendron tulipiferaL.), American beech (Fagus grandifoliaEhrh.), and Scotch pine (Pinus sylvestrisL.) suffered minimal and temporary injury from these herbicides.

Background. Identification of spectacular ornamental perennial lianas for urban landscaping in southern cities is important for modern urban greening programs. The aim of this work was to study flowering peculiarities of Japanese honeysuckle (Lonicera japonica Thunb.).Materials and methods. The target material was honeysuckle plants growing in the environments of Southern Uzbekistan. Observations were conducted in 2019–2020 using conventional approaches.Results and conclusion. The inflorescence of L. japonica is an open dibotryoid, with flowers arranged along the lateral axes of the first order. Flowers are bisexual, zygomorphic. Blossoming of flowers in inflorescences occurs acropetally. The flowering period is almost 150–170 days (starts in April and lasts until the end of August). Dichogamy in the form of proterandry is observed in honeysuckle flowers. The male flowering phase comes the first. It starts 1.5–2.0 hours after the opening of the corolla and ends with the drying of the stamens. The corolla turns yellow 36 hours after the blooming of the flower and the stamens begin to dry out. This is the female phase. Over the next 84 hours, the pistil begins to dry out slowly, but the corolla of the flower lasts up to 96 hours. The duration of the female flowering phase is 60 hours. L. japonica is of considerable interest for vertical landscaping of urban communities. Plants remain ornamental for a long time. Studying this species as an essential oil plant is promising, since it contains a significant amount of germacrene D.
