Abstract The aim of this study was to propose an efficient method of Pennisetum x advena ‘Rubrum’ micropropagation. Agar cultures with MS medium supplemented with BAP in various concentrations (0.5 mg/L-2 mg/L) and a temporary immersion bioreactor system (TIS) with liquid medium MS with an addition of 1 mg/L BAP were used. For rooting ½ MS medium with different auxin combinations (IBA, NAA) and activated charcoal was utilized. The most efficient method turned out to be TIS which produced 36.9 new plants in four weeks. The seedlings were slender in shape, bright green in colour with no signs of hyperhydricity. The most suitable agar medium produced 19.5 new plants in an eight week period. Rooting should be carried on ½ MS supplemented with 0.5 mg/L IBA and 0.5 mg/L NAA with an 84% rooting rate. The addition of activated charcoal inhibited rooting.

Pineapple is an important edible fruit in the family Bromeliaceae popularly grown in the tropical and subtropical countries. Commercial prodution of pineapple requires large volume of planting materials which could not easily be obtained using conventional method of propagation. A protocol for mass propagation of pineapple (Ananas comosus L. var.smooth cayenne) using temporary immersion bioreactor system has been developed.The protocol involves four immersion cycles in Murashinge and Skoog (MS) media fortified with 1mg/L or 2mg/L 6-Benzylaminopurine (BAP) with or without 0.25g/L activated charcoal (AC). The highest multiplication rate (120 -130 plants/bottle) was obtained when media was fortified with 1mg/l or 2mg/L BAP alone. The presence of activated charcoal (AC) promoted root morphogenesis, resulting in significant increase in roots formation in BAP suplemented media. A combination of BAP with AC significantly increased the number of competent plants(20 – 30 plants/bottle) after four weeks of culture in temporary immersion system. The system is recommended for rapid and efficient micropropagation of pineapple.

Temporary Immersion Bioreactors (TIBs) are used for increasing plant quality and plant multiplication rates. These TIBs are actioned by mean of a pneumatic system. A failure in the pneumatic system could produce severe damages into the TIB. Consequently, the whole biological process would be aborted, increasing the production cost. Therefore, an important task is to detect failures on a temporary immersion bioreactor system. In this paper, we propose to approach this task using a contrast pattern based classifier. We show that our proposal, for detecting pneumatic failures in a TIB, outperforms other approaches reported in the literature. In addition, we introduce a feature representation based on the differences among feature values. Additionally, we collected a new pineapple micropropagation database for detecting four new types of pneumatic failures on TIBs. Finally, we provide an analysis of our experimental results together with experts in both biotechnology and pneumatic devices.
