Dog rose (Rosa canina) is one of the most important flower crops in the world and has a value in ornamental, pharmaceutical and cosmetic trade. Also it was used as a root stock for other cultivars of Rose. Hence this investigation was attempted with the aim to study direct regeneration of Rosa canina. The experimental data of the present investigation was analyzed statistically by using complet...

We investigated the biosynthetic pathway for 2-phenylethanol, the dominant floral scent compound in roses, using enzyme assays. L-[(2)H8] Phenylalanine was converted to [(2)H8] phenylacetaldehyde and [(2)H8]-2-phenylethanol by two enzymes derived from the flower petals of R. 'Hoh-Jun,' these being identified as pyridoxal-5'-phosphate-dependent L-aromatic amino acid decarboxylase (AADC) and phen...

The lipid microviscosity of microsomal membranes from senescing cut carnation (Dianthus caryophyllus L. cv. White Sim) flowers rises with advancing senescence. The increase in membrane microviscosity is initiated within 3 to 4 days of cutting the flowers and coincides temporally with petal-inrolling denoting the climacteric-like rise in ethylene production. Treatment of young cut flowers with a...

A coupled model of leaf photosynthesis and stomatal conductance as a function of photosynthetically active radiation (PAR), CO2, leaf temperature, relative humidity, and leaf age was calibrated for rose leaves. The photosynthetic parameters: maximum carboxylation rate (Vcmax), potential rate of electron transport (Jmax), rate of triose phosphate utilization (TPU), and leaf dark respiration rate...

Nanostructured surface possessing ultrahigh adhesion like "gecko foot" or "rose petal" can offer more opportunities for bionic application. We grow flower-like few-layer graphene on silicon nanocone arrays to form graphene nanoclusters, showing robust adhesion. Their contact angle (CA) is 164° with a hysteresis CA of 155° and adhesive force for a 5 μL water droplet is about 254 μN that is far l...

Rose is among the most important cut flower crops worldwide. The vase life an indicator of rose quality. composition solution directly affects life. Neoagaro-oligosaccharides (NAOS) are degraded seaweed-derived polysaccharides that constitute a group compounds with small molecular weight and good water solubility. Oligosaccharide treatment can extend postharvest longevity certain types flowers;...

Introduction: Rose (rosa canina) is one of the flowers that are much in demand by community because besides being an ornamental flower it can also be used as a cosmetic. Traditional medicinal herbs have seen rebound recent years, and result, pharmaceutical companies investing heavily developing natural medications derived from plants. Aim: To study Anti-diabetic activity Jasmine formulation med...
