Effects of silicon on the growth and genetic stability of passion fruit Agronomy
Costa, Bárbara Nogueira Souza; Dias, Gabrielen de Maria Gomes; Costa, Irton de Jesus Silva; Assis, Franscinely Aparecida de; Silveira, Flávia Aparecida da; Pasqual, Moacir.
The objective of this study was to determine the silicon concentration that would provide good growth in passion fruit plants. Passion fruit seeds were sown in polystyrene. After 60 days, when they were approximately 15 cm tall, the plants were transplanted into polyethylene pots containing 1.1 kg Tropstrato® substrate. Treatments consisted of four concentrations (0, 0.28, 0.55, and 0.83 g pot-1) of silicon applied as a silicic acid solution 1%. This solution was applied around the stem of the plants (drenched), with the first application being administered 15 days after transplanting. In total, three applications were made at intervals of 15 days. After the last application, the plants were subjected to chemical analysis to determine the silicon...

Induction embryogenic callus torch ginger in vitro Sci. Agrar.Paran. / SAP
Dias, Gabrielen de Maria Gomes; Pasqual, Moacir; de Carvalho, Ana Cristina Portugual Pinto.
With the purpose of obtaining embryogenic calluses, different auxins and inoculation position of the explants were evaluated. Rhizomes of about 0.5cm obtained from micropropagated seedlings were cut lengthwise at half and inoculated in test tubes. After inoculation, the cultures were kept in growth room at 25±2ºC in the dark. The completely randomized design in a factorial scheme 6x2, represented by five auxins (ANA; AIB; AIA; 2,4-D and picloram) at the concentration of 10µM and a control (without auxin) and two explant positions (H-horizontal and V-vertical). The experiment was constituted of five replicates with three tubes each containing one explant. After 50 days’ cultivation, both the percentage of oxidation and callus formation were evaluated. The...
