Modification of Flower Color Pigments and Color Composition with Hormonal Treatments and Sucrose in Tulipa gesneriana ‘Kingsblood’
Authors
Abstract:
Three separate experiments were conducted to investigate the interplay between three phytohormones and sucrose for the change of flower color composition and the plant secondary metabolites in Tulipa. The variations of the physiological and morphological characteristics, with ABA at 5 and 10 mg/L (as experiment one), GA3 at 300 and 500 mg/L (as experiment two), 50 and 100 µM of JA (as experiment three) and their interactions with sucrose at 1 and 2 g/L were analyzed. By reviewing the HPLC charts and UV-Vis spectra, it was found that the production of plant secondary metabolites, total flavonoids, and anthocyanins composition pigments was influenced by the foliar application of the plant hormones. The sucrose alone had no significant effect on the quantification of different phytochemicals, but the interaction with JA and ABA showed a considerable variation in the anthocyanin accumulation and total flavonoids. Both JA and ABA hormones, in spite of enhanced anthocyanin accumulation and increased cyanidin and pelargonidin pigment percentage, were associated with reduced vegetative growth parameters as well as vase life, compared to the control plants. However, GA3 at 500 mg/L without sucrose played a key role in the accumulation of anthocyanin, postharvest performance, and the increase in the three major anthocyanin pigments. Moreover, the data provided evidence of interference between the sucrose and GA3 in the regulation of the anthocyanin accumulation.

Blue metal complex pigments involved in blue flower color
The blue pigment of cornflower, protocyanin, has been investigated for a long time, but its precise structure was not entirely explained until recently. The molecular structure of the pigment was recently shown to be a metal complex of six molecules each of anthocyanin and flavone glycoside, with one ferric iron, one magnesium and two calcium ions by X-ray crystallographic analysis. The studies...

A research trial was conducted during 2011-2012 to elucidate the effects of humic acid (HA) and NPK to determine the optimum rate against different growth and floral attributes on tulip cultivar viz. ‘Triumph’. The following five treatments T0 : (control), T1: 10 g/m2 NPK (17:17:17), T2 : HA 0.75 ml (8%) + 10 g/m2 NPK (17:17:17), T3: HA 1.00 ml (8%) + 10 g/m2 NPK (17:17:17) and T4: HA 1.25 ml (...

ABSTRACT-Manual harvesting of saffron as a laborious and exhausting job; it not only raises production costs, but also reduces the quality due to contaminations. Saffron quality could be enhanced if automated harvesting is substituted. As the main step towards designing a saffron harvester robot, an appropriate algorithm was developed in this study based on image processing techniques to recogn...

Composition of Carotenoids and Flavonoids in Narcissus Cultivars and their Relationship with Flower Color
Narcissus is widely used for cut flowers and potted plants, and is one of the most important commercial bulbous flowers in the floricultural industry. In this study, ten carotenoid and eighteen flavonoid compounds from the perianths and coronas of fifteen narcissus cultivars were measured by HPLC-APCI-MS/MS and UPLC-Q-TOF-MS/MS. Among these, six carotenoids, a total of seventeen flavonols and c...
