ABSTRACT
The wax apple or jambu madu, is a non-climacteric tropical fruit from Myrtaceae family and widely cultivated in South East Asia. The limited availability of good quality seedlings of wax apple is the main problem to development of flourish it's market share in the current fruit industry. Therefore, in order to produce good quality planting materials, a study aimed at optimizing propagation and adventitious rooting technique and survivability of wax apple air layer was conducted. In this study, four different levels of Indole-3-Butyric Acid (IBA) concentration (0, 1000, 1500 and 2000 mg L-1) and three rooting media (sphagnum moss, vermicompost and garden soil) were applied after removal of bark (phloem) on the shoot to determine the effect on rooting and survivability of the wax apple air layer under field conditions. The results showed that the wax apple shoots treated with 2000 mg L-1 IBA produced the significantly higher number of roots, increased length of root, diameter of branch, length of branch, number of leaf and leaf area of air layers. In addition, the highest chlorophyll content and stomatal aperture were recorded in 2000 mg L-1 IBA treatment compared to other treatments including control. Vermicompost medium was better than garden soil and sphagnum moss in respect of rooting and survivability of air layers. The results showed that the combination of 2000 mg L-1 IBA and vermicompost as rooting media give the best combination to root initiation, root number, root length and survival rate (100%) of wax apple air layers. From this study, it can be concluded that 2000 mg L-1 IBA and vermicompost treatment enhance the root initiation, early establishment and survivability of wax apple air layered under field conditions.
RESUMO
A maçã de cera, ou jambu madu, é uma fruta tropical não climatérica da família Myrtaceae e amplamente cultivada no Sudeste Asiático. A disponibilidade limitada de mudas de macieira de boa qualidade é o principal problema para o desenvolvimento de sua participação de mercado na fruticultura atual. Portanto, com o objetivo de produzir materiais de plantio de boa qualidade, foi realizado um estudo visando otimizar a técnica de propagação e enraizamento adventício e a sobrevivência da camada aérea da cera de macieira. Neste estudo, quatro diferentes níveis de concentração de ácido indol-3-butírico (AIB) (0, 1000, 1500 e 2000 mg L-1) e três meios de enraizamento (musgo esfagno, vermicomposto e solo de jardim) foram aplicados após a remoção da casca (floema) na parte aérea para determinar o efeito no enraizamento e capacidade de sobrevivência da camada de ar da macieira em condições de campo. Os resultados mostraram que os brotos de macieira tratados com 2000 mg L-1 de AIB produziram significativamente maior número de raízes, maior comprimento de raiz, diâmetro de galho, comprimento de galho, número de folhas e área foliar das camadas aéreas. Além disso, o maior teor de clorofila e abertura estomática foram registrados no tratamento 2000 mg L-1 IBA em comparação com outros tratamentos, incluindo o controle. O meio de vermicomposto foi melhor do que o solo de jardim e o musgo esfagno em relação ao enraizamento e capacidade de sobrevivência das camadas aéreas. Os resultados mostraram que a combinação de 2000 mg L-1 de AIB e vermicomposto como meio de enraizamento proporciona a melhor combinação para iniciação radicular, número de raízes, comprimento radicular e taxa de sobrevivência (100%) das camadas aéreas de macieira. A partir deste estudo, pode-se concluir que 2.000 mg L-1 de AIB e tratamento com vermicomposto melhoram a iniciação radicular, o estabelecimento precoce e a capacidade de sobrevivência de macieiras em camadas de ar em condições de campo.
