C.  aFormation of 'Flying Dragon' and 'Swingle' RootstocksbSubstrates and Tegument in the Emergence of Seedlings.h[electronic resource]  c2018  aThe production of citrus seedlings in Santa Catarina State has grown in the last few years. However, the process of seedlings production needs adjustment in order to optimize the system to get genetic material with high phytotechnical standard that allows greater profitability to the producer. The objective with the present study is to evaluate the effect of different substrates and the removal of tegument in the seedlings formation of 'Swingle' and 'Flying Dragon' rootstocks. The experimental design was completely randomized in a 2x4x2 factorial design, with 2 rootstocks, 4 substrates and absence and presence of tegument. The formulated presented the lowest value for both germination and germination speed index, for which reason the others evaluation were disregarded. About the rootstocks, the ?Swingle? showed better results with the removal of tegument, for the other hand, seeds of ?Flying Dragon? were better with tegument. The commercial substrate 1 and 3 provided higher mean values for both rootstocks in the root length variable, indicating the dependence of soil conditions on the root system. In the aerial part size, genetic characteristics exceed the interaction with the substrate factor, presenting greater development of ?Swingle?. It was concluded that is not favorable the removal of the tegument because the low cost benefit. The most promising rootstock was ?Swingle? and the commercial substrates 1 and 3.  aCitrus spp  aPoncirus spp  apropagation1 aFOREST, V.
