ABSTRACT:       Soybean  farmers  have  been  using  desiccation  to  anticipate  harvesting,  however,  this  technique  is  frequently  questioned when used in seeds production fields, since residues left by desiccants may harm the seeds quality, especially those with fragile tegument. The aim of this study was to evaluate how desiccants applied in different times affect the quality of soybean seeds  with  different  lignin  content  in  the  tegument.  Plants  of  cultivars  BRS  Silvânia  RR,  BRS  Valiosa  RR,  BRS  245  RR,  and  BRS 247 RR were desiccated with three commercial herbicides, besides one control treatment, in three application times, when seeds showed 30, 40, and 50% of water content. Seeds quality was evaluated performing the tests of germination, emergence, emergence  speed  index,  accelerated  aging,  electrical  conductivity,  tetrazolium  and  seed  yield.  The  lignin  content  in  soybean  seeds has high negative correlation with seed yield and with traits related to the seeds quality. In general, the plants desiccation with the herbicide Finale® harms the seeds quality.

RESUMO:      Produtores  de  soja  tem  utilizado  herbicidas  dessecantes  para  antecipar  a  colheita,  entretanto,  essa  prática  é  frequentemente questionada quando utilizada em campos de produção de sementes, uma vez que os resíduos deixados pelos herbicidas dessecantes podem prejudicar a qualidade das mesmas, especialmente daquelas com tegumento frágil. O objetivo nesse  estudo  foi  avaliar  como  dessecantes  aplicados  em  diferentes  épocas  afetam  a  qualidade  de  sementes  de  soja  com  diferentes teores de lignina no tegumento. Plantas das cultivares BRS Silvânia RR, BRS Valiosa RR, BRS 245 RR e BRS 247 RR foram dessecadas com três herbicidas comerciais, além de um tratamento controle, em três épocas de aplicação, quando as sementes estavam com teores de água de 30, 40 e 50%. A qualidade das sementes foi avaliada pelos testes de germinação, emergência, índice de velocidade de emergência, envelhecimento acelerado, condutividade elétrica, tetrazólio e produtividade. Para o teor de lignina das sementes de soja há alta e negativa correlação com a produtividade e os caracteres relacionados à qualidade fisiológica das sementes. A dessecação das plantas com o herbicida Finale® prejudica a qualidade das sementes.
