Objetivou-se avaliar a influ那ncia de n赤veis de adubos organicos bovino e av赤cola no teor de clorofila e caracter赤sticas anat micas de folhas de plantas de or谷gano cultivadas em casade- vegeta o. Foram conduzidos dois ensaios separadamente, sendo um com esterco bovino e ooutro com esterco de aves. Plantas de or谷gano (Origanum vulgare L.) foram cultivadas em vasos de 10 L, submetidas aos seguintes tratamentos: Ensaio I: esterco bovino: 1) solo sem aduba o(controle); 2) solo + 3,0 kg m-2 de esterco bovino; 3) solo + 6,0 kg m-2 de esterco bovino; 4) solo + 9,0 kg m-2 de esterco bovino; 5) solo + 12,0 kg m-2 de esterco bovino; Ensaio II 每 esterco av赤cola: 1) solo sem aduba o (Controle); 2) solo + 1,5 kg m-2 de esterco de galinha; 3) solo + 3,0 kg m-2 de esterco de galinha; 4) solo + 4,5 kg m-2 de esterco de galinha e 5) solo + 6,0 kg m-2 de esterco de galinha. Os ensaios foram conduzidos no delineamento experimental em blocos casualizados, com quatro repeti es, e a parcela experimental foi composta por quatro vasos. Observou-se que os n赤veis de esterco bovino e de aves influenciaram o teor de clorofila e caracter赤sticas anat micas das folhas de or谷gano. This study was performed to evaluate the effect of different levels of cattle and chicken manure organic fertilization in thechlorophyll content and anatomic parameters of leaves of Origanum vulgare L. cultivated in greenhouse. Two assays were carried out separately, one with cattle manure and the other with chicken manure. Origanum vulgare L. plants were cultivated in 10 L pots with the following treatments: Trial I: Cattle manure: 1) Soil without fertilization (control); 2) Soil + 3.0 kg m-2 of cattle manure; 3) Soil + 6.0 kg m-2 of cattle manure; 4) Soil + 9.0 kg m-2 of cattle manure; 5) Soil + 12.0 kg m-2 of cattle manure; Trial II: Chicken manure: 1) Soil without fertilization (Control); 2) Soil + 1.5 kg m-2 of chicken manure; 3) Soil + 3.0 kg m-2 of chicken manure; 4) Soil + 4.5 kg m-2 of chicken manure and 5) Soil + 6.0 kg m-2 of chicken manure. Both trials were carried out in randomized blocks with 4 repetitions and 4 pots per experimental parcel. It was observed thatthe levels of organic fertilization significantly influenced the chlorophyll content and anatomic parameters of wild marjoran leaves.
