ACIDO INDOL BUTIRICO PDF

Rooting of semi-hardwood litchi cuttings using indolbutiric acid. O objetivo deste trabalho foi estudar o enraizamento de estacas semilenhosas de lichieira Litchi chinensis Sonn. The objective of the work was to study the rooting of semi-hardwood litchi cuttings Litchi chinensis Sonn. The apical cuttings were collected in October spring in Brazil , January summer and April fall. The cuttings were properly arranged and transferred to greenhouse with intermittent mist and treated with 0, , , and mg L -1 indolbutiric acid applications, having the cuttings bases been immersed during 10 seconds and with mg L -1 indolbutiric acid application, having the bases been immersed for 24 hours in aeration. They were put to rooting in vermiculite substratum with carbonized rice husk.

The objective of the work was to study the rooting of semi-hardwood litchi cuttings Litchi chinensis Sonn.

The cuttings were properly arranged and transferred to greenhouse with intermittent mist and treated with 0, , , and mg L -1 indolbutiric acid applications, having the cuttings bases been immersed during 10 seconds and with mg L -1 indolbutiric acid application, having the bases been immersed for 24 hours in aeration. They were put to rooting in vermiculite substratum with carbonized rice husk. After days, the data referring to live cuttings with leaves percentage, the rooted cuttings percentage for each parcel, average root length per rooted cutting in centimeters , average number of roots formed per cutting, average weight of the roots fresh matter in grams were obtained, average weight of the root dry matter in grams were obtained.

By the results it was concluded that there is no need of indolbutiric acid for the litchi cuttings, Bengal cultivar rooting and the best time for collecting the cuttings is summer. Index terms: Litchi chinensis , plant regulators, vegetative propagation, auxins. Posteriormente, as estacas foram preparadas de modo a apresentarem 20 cm de comprimento e 2 folhas cortadas ao meio.

Rooting of juvenile cuttings of Bertholletia excelsa under different concentrations of indolebutyric acid. Iracema M. Recalcitrant behavior and slow and irregular germination are limiting factors for the production of Bertholletia excelsa seedling production, through the conventional process. The objective of this study was to evaluate the rooting of juvenile cuttings of B. The experimental design was completely random with a factorial arrangement of 3x3x2 of treatments: three doses 0, and mg L -1 of IBA as growth regulator; three types of cuttings apical, middle, basal ; and two immersion times 1 s and 60 s.
