Rosa centifolia and Rosa gruss an teplitz distillation waste biomass was immobilized using sodium alginate for Pb(II) uptake from aqueous solutions under varied experimental conditions. The maximum Pb(II) adsorption occurred at pH 5. Immobilized rose waste biomasses were modified physically and chemically to enhance Pb(II) removal. The Langmuir sorption isotherm and pseudo-second-order kinetic ...

Pratylenchus vulnus is involved in a desease of Rosa noisettiana 'Manetti' rose rootstock characterized by darkening of roots, death of feeder roots, and stunting of entire plants.

Overexpression of the flavonoid 3′,5′-hydroxylase F3′5′H gene can increase accumulation pigment (delphinidin anthocyanin). However, sometimes effect alone is inadequate for producing flowers. Furthermore, internal environment cell, such as an in pH, also help conversion anthocyanins to pigments. Nonetheles...
