Influência do hidrogel e irrigação no desenvolvimento de mudas do híbrido vm 01 (Eucalyptus urophylla S.T. Blake x Eucalyptus camaldulensis Dehnh)

Abstract

The Eucalyptus belongs to the family Myrtaceae and has great productive potential for the wood production. The objective of this work was to evaluate the development of eucalypto clone seedlings, VM01 (UROCAM) with the use of hydrogel at different irrigation frequencies. The experimental design was completely randomized in 2 x 5 factorial scheme (with and without hydrogel application and five irrigation times) with 4 replicates of 4 experimental units represented by bags containing one seedling each. The variables analyzed in the study were: Number of leaves; collecting diameter; shoot length; length of the largest root; dry matter of shoot; root dry matter and Dickson quality index. The results obtained in the work showed that seedlings of the eucalypto hybrid VM 01 can be produced without the use of irrigation at intervals of up to 15 days, regardless of hydrogel application.
