Intensidades luminosas alteram o crescimento e óleo essencial de patchouli sob malhas

Autoria SCIMAGO INSTITUTIONS RANKINGS

RESUMO:

Pogostemon cablin (Blanco) Benth. é uma espécie aromática popularmente conhecida como patchouli. O óleo essencial rico em patchoulol extraído de folhas é utilizado pelas indústrias farmacêuticas. O objetivo foi investigar os efeitos das malhas e intensidades de sombreamento no crescimento, anatomia, composição química e teor de óleo essencial de P. cablin. O experimento foi conduzido com dois tipos de malhas (preta e Aluminet), três intensidades de luz (30, 50 e 70% de sombreamento) e pleno sol. As diferentes intensidades de luz influenciaram o crescimento, o rendimento e a composição química do óleo essencial. Plantas de patchouli cultivadas em ambiente sombreado apresentaram maiores valores para os pesos secos de folha, caule, raiz e total em relação ao pleno sol. Com 50% de sombreamento, Aluminet proporcionou ganho de peso seco de caule e total. Aluminet e malha preta a 50 e 70% de sombreamento aumentam o rendimento do óleo essencial. Os teores de patchoulol e pogostol foram maiores a pleno sol, malha preta e Aluminet com 50% de sombreamento. O ambiente para o cultivo do patchouli pode ser melhorado com o uso de malhas de sombreamento, especialmente com Aluminet em 50% de sombreamento.
