| The effect of the nutrient solution concentration on potato plant growth and minituber yield were determined in a sand closed hydroponic system. Minitubers and micropropagated plantlets of the cv. 'Macaca' were used. Treatments were five nutrient solution concentrations at electrical conductivities (EC) of 1.0 (T1), 2.2 (T2), 3.4 (T3), 4.7 (T4) and 5.8dS m-1 (T5). The split plot randomised experimental design was used with three replications. Plants from minitubers produced higher fresh and mean weight of minitubers, shoot dry mass and leaf area index than the micropropagated ones. However, higher dry mass of minitubers was found with micropropagated plantlets compared to minitubers. The concentration of the nutrient solution did not affect minituber... |

| En un primer experimento se evaluó la aclimatación de vitroplantas de caña de azúcar de las variedades MEX69290 y CP722086 en tres sustratos; 1) TBZ: tezontle + bagazo de caña, 2) TCA: Tezontle + cascarilla de arroz y 3) TCZ: tezontle + cachaza; las mezclas en éstos en una proporción 40/60 (v/v). Las variables evaluadas fueron porcentaje de sobrevivencia, altura de plántula, diámetro de tallo, biomasa seca, azúcares solubles totales y concentración nutrimental. Las últimas tres variables fueron evaluadas en los vástagos y raíces. Se utilizó un diseño experimental completamente al azar con cincuenta repeticiones por tratamiento. A los 30 d, la menor sobrevivencia de la variedad MEX69290 fue de 84%;, mientras que la de CP722086 de 64%; en ambos casos en el... |

| The lack of good quality planting material has limited the expansion and contributed to yield reduction of the Brazilian pineapple culture. Alternatives of 'Pérola' pineapple slips management were studied aiming at obtaining superior planting material within a shorter time period and making good use of healthy slips of low vigor, that are commonly discarded by growers. Two experiments were carried out at the Experimental Field of Embrapa Cassava & Fruits, Cruz das Almas, Bahia, Brazil, and another one in a commercial plantation in the region of Itaberaba, BA, using blocks or entirely randomized designs with at least four replications. In the first one, the development of slips of different initial sizes (6 to 20 cm long), when grown on mother... |

| Abstract Pineapple is one of the most important fruits, with large production in tropical and subtropical regions and great appreciation by consumers all over the world. The pineapple plant has many specific morphological, anatomical and physiological characteristics that determine crucial aspects of pineapple crop management, such as flower induction, water use and vegetative methods of propagation. The use of sexual reproduction of pineapple is restricted to breeding purposes carried out by research institutes looking for new hybrids with improved agronomic characteristics. Seeds are only produced if cross pollination among varieties occurs. Commercially pineapple has to be propagated by vegetative material, an asexual reproduction, without new... |
