Physiological quality of seeds of citrus during cooling conditions storage

Aimed to evaluate the effect of storage on emergence and force of the rootstocks Citradia 1708, Citrandarin 1710, Citrange Carrizo, Rangpur lime, Trifoliata Limeira, Rangpur x Swingle 1707 seeds stored in High density polyethylene (HDPE) at 5-7°C and relative humidity of 70% for 210 days. The emergence, emergence speed index and seed moisture content were performed each 30 days. The experimental design was a completely randomized design with four replications. The storage in that conditions cited showed that the seeds of Rangpur with moisture content inferior to 9% still showed 66.94% and 2.03 for germination and IVE, respectively. For the maintenance of the viability of seeds of the rootstocks Citradia 1708, Citrandarin 1710, Citrange Carrizo, Rangpur x Swingle 1707, moisture content could be kept between 35-40%. Seed viability of the rootstocks Rangpur x Swingle 1707, Citradia 1708 and Citrange Carrizo was maintained for until 150 days.
