Growth seeling of Euterpe edulis Martius in response to different doses of match
Este trabalho teve por objetivos avaliar o efeito de dosagens de
f\uf3sforo no crescimento de mudas de palmiteiro, bem como determinar
o teor de macro e micronutrientes do sistema radicial e a\ue9reo
dessa planta. O ensaio foi conduzido em casa de vegeta\ue7\ue3o. Os
tratamentos foram quantitativos e eq\ufcidistantes, constitu\ueddos
por: T1-testemunha solo sem adi\ue7\ue3o de f\uf3sforo (P); T2-90
mg.kg-1; T3-180 mg; T4-270 mg.dm-3; T5-360mg dm-3; T6-450 mg.dm-3;
T7-540 mg.dm-3; T8-630 mg.dm-3; de P respectivamente. Decorridos 12
meses da semeadura, foram avaliadas vari\ue1veis: altura e biomassa
a\ue9rea, radicial e total, pela an\ue1lise nutricional dos
tecidos. Os resultados indicam que houve crescimento de plantas jovens
de palmiteiro para todos os par\ue2metros avaliados. O crescimento em
altura e o aumento da biomassa a\ue9rea das plantas jovens de palmito
foram at\ue9 a dosagem de 540 mg.dm-3 de f\uf3sforo. A resposta foi
positiva para o desenvolvimento da biomassa radical at\ue9 a dosagem
de 450 mg.dm-3, sendo que o desenvolvimento de biomassa total foi
alcan\ue7ado com a dosagem de 540 mg.dm-3 de f\uf3sforo. Para os
teores de macro na biomassa a\ue9rea obteve-se a seguinte
seq\ufc\ueancia, respectivamente: N > Ca > K > Mg >
P>S; e micronutrientes Fe > Mn > Zn > B > Cu; e para
radical: N > Ca > Mg > S > K > P; Fe > Mn > Zn
> B > Cu, sendo que os teores de P n\ue3o alteraram os teores
de nutrientes na planta.The objective of this work was to evaluate the effect of phosphorus
doses in the growth of seedling of palm as well as to determine the
content of macro and micronutrients from the below and above ground
biomass through a tissue analysis. The assay was conducted in a
greenhouse. The treatments were quantitative and equidistant,
constituted by: T1- control (soil without P); T2-90 mg.dm-3; T3-180
mg.dm-3; T4-270 mg.dm-3; T5-360 mg.dm-3; T6-450 mg.dm-3; T7-540
mg.dm-3; T8-630 mg.dm-3; of P, respectively. 12 months after sowing,
the following variables were evaluated: above ground height and
biomass, below ground biomass and total. The nutritional analysis from
below and above ground biomass was done to obtain the amount of macro
and micronutrients. Results show that the growth of young palm plants
was achieved to the analyzed parameters. Growth was obtained for height
and it increased the aerial biomass of the plants to the doses of 540
mg.dm-3 of P, the answer was positive for the development of the below
ground biomass to the doses of 450 mg dm-3, and the development of
total biomass was reached with the doses of 540 mg.dm-3. For the macro
tenors and micronutrients in the above ground biomass, the following
sequence has been obtained, respectively: N> Ca> K> Mg>
P>S; Fe> Mn> Zn> B> Cu, and for below ground: N>
Ca> Mg> S> K> P; Fe> Mn> Zn> B> Cu, and the
tenors of P didn't alter the tenors of nutrients in the plant
