Repartição de nutrientes nas flores, folhas e ramos da laranjeira cultivar Natal Repartition of nutrients in citrus flowers, leaves and branches
As plantas cítricas produzem elevado número de flores, porém pequena porcentagem chega a fruto maduro. A fixação é influenciada por diversos fatores, com destaque para os nutricionais orgânicos e minerais. O objetivo do trabalho foi verificar a repartição de macro e micronutrientes nas flores, folha...

| 520 | |a As plantas cítricas produzem elevado número de flores, porém pequena porcentagem chega a fruto maduro. A fixação é influenciada por diversos fatores, com destaque para os nutricionais orgânicos e minerais. O objetivo do trabalho foi verificar a repartição de macro e micronutrientes nas flores, folhas e ramos de laranjeira e a contribuição nutricional das flores para os demais órgãos. Plantas de Citrus sinensis L., cultivar Natal sobre porta-enxerto de limoeiro cravo de 10 anos de idade, provenientes de pomar comercial, foram amostradas por ocasião do fluxo primaveril e separadas em flores, folhas e ramos. As flores representam dreno tanto para compostos orgânicos quanto para macro e micronutrientes. Sua massa seca na antese se iguala às das folhas e é maior que a dos ramos. A maior proporção de Ca, Mg e de Ni das três partes encontram-se nas flores de onde, possivelmente, passam em parte para o fruto em desenvolvimento. Sugere-se que aplicações foliares de cálcio, magnésio e níquel, em condições de deficiência, poderiam aumentar a produção através do seu efeito no florescimento.<br<Citrus plants produce a number of flowers, but just a few of them however, become mature fruits. Many factors, as well as organic and inorganic nutrients, influence prebloom and flowers setting. The objective of this work was to evaluate the repartition of macro and micronutrients in citrus flowers, leaves and branches. Branches of "Natal" sweet orange (Citrus sinensis L.) grafted on Rangpur lime rootstock were collected and separated in flowers, leaves and wood during anthesis. Orange flowers represent a drain for organic compounds and macro and micronutrients as well. Their dry matter on anthesis is equal to that of leaves and higher than that of the branches. The highest proportion of Ca, Mg and Ni of the three parts is found in the flowers where possibly migrate in part, into the developing fruits. It is thought that leaf sprays of calcium, magnesium and nickel could raise yield under conditions of deficiency due to their effect on flowering. | ||

Repartição de nutrientes nas flores, folhas e ramos da laranjeira cultivar Natal Repartition of nutrients in citrus flowers, leaves and branches |
| abstract |
As plantas cítricas produzem elevado número de flores, porém pequena porcentagem chega a fruto maduro. A fixação é influenciada por diversos fatores, com destaque para os nutricionais orgânicos e minerais. O objetivo do trabalho foi verificar a repartição de macro e micronutrientes nas flores, folhas e ramos de laranjeira e a contribuição nutricional das flores para os demais órgãos. Plantas de Citrus sinensis L., cultivar Natal sobre porta-enxerto de limoeiro cravo de 10 anos de idade, provenientes de pomar comercial, foram amostradas por ocasião do fluxo primaveril e separadas em flores, folhas e ramos. As flores representam dreno tanto para compostos orgânicos quanto para macro e micronutrientes. Sua massa seca na antese se iguala às das folhas e é maior que a dos ramos. A maior proporção de Ca, Mg e de Ni das três partes encontram-se nas flores de onde, possivelmente, passam em parte para o fruto em desenvolvimento. Sugere-se que aplicações foliares de cálcio, magnésio e níquel, em condições de deficiência, poderiam aumentar a produção através do seu efeito no florescimento.<br<Citrus plants produce a number of flowers, but just a few of them however, become mature fruits. Many factors, as well as organic and inorganic nutrients, influence prebloom and flowers setting. The objective of this work was to evaluate the repartition of macro and micronutrients in citrus flowers, leaves and branches. Branches of "Natal" sweet orange (Citrus sinensis L.) grafted on Rangpur lime rootstock were collected and separated in flowers, leaves and wood during anthesis. Orange flowers represent a drain for organic compounds and macro and micronutrients as well. Their dry matter on anthesis is equal to that of leaves and higher than that of the branches. The highest proportion of Ca, Mg and Ni of the three parts is found in the flowers where possibly migrate in part, into the developing fruits. It is thought that leaf sprays of calcium, magnesium and nickel could raise yield under conditions of deficiency due to their effect on flowering. |
