“…There is a possibility of having a high quantity of anthocyanin in vegetative organs in this genus and so further investigations are needed to analyze pigment content in vegetative and floral organs of the whole plant. When an explant is inoculated in vitro, diverse responses are expected and factors determining chemical and physiological characteristics of the tissues donor plants seem to be crucial (Borgatto et al, 2002). According to these researchers as well as the opinion of Ball et al (1972), in consistence with our results, the higher quantity of chlorophyll in vegetative explants is confirmed because vegetative segments have considerable chlorophyll in the whole plant.…”

Callogenesis using vegetative (leaf, stem, petiole) and floral (petal, pistil, anther) explants of Rosa gallica and R. hybrida was investigated using different combinations of 2,4-dichlorophenoxyacetic acid, 6-benzylaminopurine, and gibberellic acid on modified Murashige and Skoog medium. The highest callogenesis was obtained on Murashige and Skoog medium containing ratios of 2 and 3 mg L -1 of 2,4-dichlorophenoxyacetic acid to 1 mg L -1 of 6-benzylamino purine in both species depending on type of explant. Stem explants in R. gallica initiated callus after 4 days while the other explants in R. gallica and all explants in R. hybrida showed the greatest percentage of callus initiation after 8 days. The callus growth rate showed much more progressive callus growth respectively on leaf and stem explants in both species. The highest callus volume was achieved after 2 months from vegetative explants and after 2.5 months from flower explants in both species. The highest anthocyanin and chlorophyll yield was produced in vegetative calluses of R. gallica but their content was less in flower calluses. In R. hybrida, the highest value of pigment was observed in calluses from leaf and stem. It is noteworthy that anthocyanin content in different calluses, especially vegetative ones in R. gallica, was much higher, while chlorophyll concentration was somewhat more in calluses derived from explants of R. hybrida.

“…The H 2 PO 4 and NO 3 removed treatment had the lowest average SPAD value. As these plants carry out lower levels of photosynthesis, they eventually accumulate less cellular material and less carbon skeleton (Borgatto et al 2002). Root induction and growth also affected according to inorganic salts.…”

The development of bioenergy through biomass has gained importance due to the increasing rates of fossil fuel depletion. Biomass is important to increase the productivity of bioethanol, and production of biomass with high biomass productivity, low lignin content, and high cellulose content is also important in this regard. Inorganic salts are important in the cultivation of biomass crops for the production of biomass with desirable characteristics. In this study, the roles of various inorganic salts in biomass and bioethanol production were investigated using an in vitro tobacco culture system. The inorganic salts evaluated in this study showed dramatic effects on tobacco plant growth. For example, H 2 PO 4 substantially improved plant growth and the root/shoot (R/S) ratio. The chemical compositions of tobacco plants grown in media after removal of various inorganic salts also showed significant differences; for example, lignin content was high after Mg 2+ removal treatment and low after K + treatment and H 2 PO 4 removal treatment. On the other hand, NO 3 and H 2 PO 4 treatments yielded the highest cellulose content , while enzymatic hydrolysis yielded the highest glucose concentration ratio 24 h after NH 4 + removal treatment. The ethanol productivity after H 2 PO 4 removal treatment was 3.95% (w/v) 24 h after fermentation and 3.75% (w/v) after 36 h. These results can be used as the basis for producing high-quality biomass for future bioethanol production.

“…A calogênese em meio de cultura MS de explantes foliares de Chrysanthemum morifolium foi influenciada pelo estado nutricional de plantas matrizes crescidas em vaso com areia e irrigada com solução nutritiva variando a concentração de potássio (0; 58,5; 117,0 e 234,0 mg L -1 ). A massa fresca dos calos obtida foi inversamente proporcional ao aumento da concentração de potássio fornecida às plantas matrizes; sugerindo que a alta concentração de potássio nos tecidos foliares pode estar interferindo na absorção e disponibilidade de cálcio ou de magnésio interferindo na calogênese e/ou no crescimento dos calos (BORGATTO et al, 2002).…”
