Rose ( Rosa L.) is an economically important ornamental genus that has been cultivated for its scent the perfume industry since antiquity. However, most modern roses have lost their fragrance during later stages of breeding process. Here, 59 species , including 24 wild species, 20 Chinese old garden roses, and 15 were examined by headspace solid-phase microextraction gas chromatography–mass spe...

the influence of explant nodal positions on the in vitro shoot growth and proliferation were studied in the two rose cvs. ‘bianca’ and ‘el torro’. third, fourth and fifth nodal explants were cultured on the modified ms medium supplemented with 1.0 and 5.0 mg/l ba. in both the cultivars, higher rate of proliferation (‘bianca’ 3.75; ‘el torro’ 2.65) were obtained from the explants distal to the a...

The Australian blueberry industry is worth over $300 million, but there limited information on factors influencing their chemical composition, particularly ripeness and harvest stage. This pilot study investigated changes in total monomeric anthocyanin content (TMAC; measured using the pH-differential method) antioxidant capacity (TAC; with cupric reducing assay) of four highbush cultivars (Den...

biosynthesis of plant pigments is affected by environmental factors especially light intensity. an expriment was conducted to evaluate the effect of different light intensities on photosynthetic and non-photosynthetic pigments of two rose cultivars including ‘red one’ and ‘gulmira’ under greenhouse conditions. in this experiment, the effects of different light intensities including 240, 520 and...
