Germination of seedlings of rootstocks of citrus at three substrates
Abstract
It was evaluated the development of Citrus rootstock on substrates composed of burn rice husk. The experiment was carried out in the Fepagro Fruticultura, Taquari – RS, using three substrates (mix, comercial substrate and burn rice husk) and two rootstocks seeds (Poncirus trifoliata and Citrus sunki ), placed in plugs (50 cm3) and cultived in a greenhouse. The experimental design was completely randomized, in a factorial (3x2), with 4 replicates and 8 seeds per plot. The seeds germination and seedlin- gs diameter were not affected by the substrate type. The seedlings reached the biggest height in the mix substrate. The burn rice husk is a alternative in the composition of substrates to seeds germination of Citrus rootstocks.
