Abstract:

The observations recorded on plant height, plant spread, leaf area, number of thorns on flower stalk, days required for first flower bud initiation, average weight of flower, length of peduncle, number of petals per flower, vase life and petal area were significantly influenced by chemical mutagens and their different concentrations. The results on days required for bud sprouting and colour of flower were not found significant. Among the various concentrations of two chemical mutagens i. e.

Abstract:

Petal senescence involves numerous programmed changes in biological and biochemical processes. Ubiquitination plays a critical role in protein degradation, a hallmark of organ senescence. Therefore, we investigated changes in the proteome and ubiquitome of senescing rose (Rosa hybrida) petals to better understand their involvement in petal senescence. Of 3859 proteins quantified in senescing petals, 1198 were upregulated, and 726 were downregulated during senescence. We identified 2208 ubiquitinated sites, including 384 with increased ubiquitination in 298 proteins and 1035 with decreased ubiq

Abstract:

Abstract Rhythmic pulses of irreversible petal expansion in rose (Rosa hybrida L. ‘Sonia’) petals cause diurnal changes in the rate of flower opening. Time-lapse cinematography revealed a transient increase in the rate of rose flower opening that commenced shortly before the onset of a light period and lasted for a few hours. Petal expansion, which occurred sequentially from the outer to the innermost whorl, involved rhythmic increases in fresh and dry weights. The amount of expansion was greatest in the distal portion of each petal and least near the petal base. Periods of rapid expansion wer

The dried powder form of the Rosa centifolia Petals was then extracted with different solvent systems alcoholic, ethyl acetate, and petroleum ether, and their extractive values were calculated. Most of the phytochemicals were foun

Abstract:

This study aims to produce a hydrophobic polymer film by mimicking the hierarchical micro/nanostructures found on the surface of rose petals. A simple and two-step UV-based nanoimprint lithography was used to copy rose petal structures on the surface of a polyurethane acrylate (PUA) film. In the first step, the rose petal was used as a template, and its negative replica was fabricated on a commercial UV-curable polymer film. Following this, the negative replica was used as a stamp to produce rose petal mimetic structures on UV curable PUA film. The presence of these structures on PUA influence

Abstract:

Frankliniella occidentalis (Pergande) is an important horticultural pest that causes serious damage to rose plants, which is one of its preferred foods. In this study, rose petals, rose flowers, and 10% honey solution + kidney bean pods were chosen as foods to assess their influence on the growth, development and fecundity of F. occidentalis. The results showed that developmental time of immature F. occidentalis with the following trend: rose flowers <10% honey solution + kidney bean pods < rose petals < kidney bean pods.

Abstract:

In this study, morphological and physiological changes in flower development of the rose (Rosa hybrida L.) in the garden were analyzed. Role of plant growth regulators on in vitro floral organogenesis of rose from floral meristem was investigated. The flowering of Rosa hybrida L. has three phases: shoot apical meristem, single floral meristem and floral bud with sepals, petals, stamens and gynoecium. Activities of cytokinins and auxins increased in the transition of shoots from vegetative growth to floral initiation stage. Floral meristems having sepals and the first layer of petals on MS medi

The aim of this research is to identify the most promising material for suppressing the enzyme elastase from common four rose (Damask, Bishop, Autumn and Lafont) species in Vietnam, as well as to compare the bioactivities of fresh and dried petals. The obtained results showed that Damask and Bishop petal extracts had the highest antioxidant activity in the DPPH assay with IC50 = 10.08 and 10.07 μg/mL, respectiv

Abstract : The efficiency of enzyme-assisted extraction for the recovery of polyphenols from rose (Rosa damascena Mill.) petals was evaluated performing a simplex centroid experimental design for mixture with three components (pectinolytic, cellulolytic and hemicellulolytic preparation). The ternary enzyme combinations leaded to the highest contents of total polyphenols, reaching 43% higher average value as compared to the control (without enzymatic treatment) sample. Enzymatic treatments also enhanced (9−25%) the extractability of total anthocyanins. The results obtained demonstrate that enzy

Organisms often have superior abilities. For example, the moth’s eyes block the reflection of light, preventing even the slightest light from escaping. Morpho butterflies have vivid colors despite their lack of pigmentation. The superhydrophobicity of lotus leaves is another example, which is attributed to their characteristic surface structure. We have recreated an interesting property by mimicking the structure of rose petals. When a drop of water falls on a rose petal, it adheres to the petal like a sphere. The droplets stay in place when the petals are inverted in this state. This phenomen

Abstract:

AGAMOUS-LIKE 24 (AGL24) is a key gene regulating floral transition, but its involvement in flower organ identity remains largely unknown. In this study, we found that RhAGL24 is strongly related to petal and stamen development in rose. Its expression increases rapidly at the petal primordium development stage and maintains a high level until the complete differentiation stage. RhAGL24 silencing increases the number of malformed petals and decreases the number of stamens, indicating that this gene affects stamen petaloidy.
