Rooting of basal offshoots of peach palm (Bactris gasipaes) Abstract Enraizamento de Perfilhos de Pupunheira (Bactris gasipaes)

This paper aims to aprimorate the technic of offshots rooting and preparing of offshoots and verify the effect of progenies and substrates on the rooting of peach palm (Bactris gasipaes Kunth. var. gasipaes Henderson) offshots. Average of survival varying from 26.6 % to 60 %, of rooting from 3.3 % t...

Zusammenfassung:This paper aims to aprimorate the technic of offshots rooting and preparing of offshoots and verify the effect of progenies and substrates on the rooting of peach palm (Bactris gasipaes Kunth. var. gasipaes Henderson) offshots. Average of survival varying from 26.6 % to 60 %, of rooting from 3.3 % to 10 %. The progenies survival average varied from 16.6 % to 26.6 % and rooting from 10 % to 16.6 %. Technic for extracting basal offshoots, presence of roots with turgid basis and meristematic tissue are principal factor for rooting of basal offshoots.   doi: 10.4336/2009.pfb.58.69 Objetivou-se, neste trabalho, aprimorar a técnica de manejo e preparo dos perfilhos e verificar o efeito de progênies e substratos no enraizamento de perfilhos de pupunheira (Bactris gasipaes Kunth. var. gasipaes Henderson). As médias de sobrevivência variaram entre 26,6 % e 60 %, e as de enraizamento de 3,3 % a 10 %. As médias de sobrevivência de progênies variaram de 16,6 % a 26,6 % e as de enraizamento de 10 % a 16,6 %. O modo de extração, a presença de raízes e base intumescida, a presença da base do perfilho e do tecido rizógeno influenciam na taxa de enraizamento dos perfilhos.   Doi: 10.4336/2009.pfb.58.69
