Begonias hold significant importance due to their use as culinary plants, medicinal remedies, decorative elements, and high-value crops. This research aims to find new explant materials for regeneration shoots and direct flowering with high frequency. In this study, high frequency shoot regeneration and in vitro flowering from petal explants of Begonia x hiemalis Fotsch were achieved. Whole petal explants disinfected with an AgNPs solution at 0.5 g/L for 15 min achieved the highest survival rate.

The results showed that SS demonstrated substantially higher impact in total (5.47 Pt) and across each of the endpoint categories, most notably human health (3.12 Pt). Further investigations demonstrated that this was largely fed by the respiratory inorganics midpoint category that accounted for 50 % of the total impact (2.75 Pt).

Purified viral protein was obtained from Potato virus Y (PVY) pure culture maintained on potato (Solanum tuberosum L.) plants. The average concentration of the purified materials was found to be 153.1 ng/µl. PVY purified virus preparation was used for immunizing rabbit for production of polyclonal antisera against the virus. Good quality antisera were collected one week post boosters (AS4b, AS5b, AS6b and AS7b) and the IgG fractions were separated through ammonium sulphate precipitation.

Melon shows a broad diversity in fruit morphology and quality, which is still underexploited in breeding programs. The knowledge of the genetic basis of fruit quality traits is important for identifying new alleles that may be introduced in elite material by highly efficient molecular breeding tools.

Natural precious products such as aroma compounds, essential oils, and bio-activated materials are usually extracted from about 30,000 botanical species. These extracts are often high competitive market due to their small content (less than 1 %) in plants and high purification cost. Thus, development of a modeling for the optimization of the crude oil extraction is highly paid attention. In this work, a modeling of Vietnam lemongrass oil extraction using steam distillation is developed and the optimization of the process parameters is performed using response surface methodology (RSM).
