title: (2-Chloroethyl)phosphonic Acid Promotes Germination of Immature Spores of Ceratopteris richardii Brongn.
abstract: Freshly collected spores of strain Hn-n of Ceratopteris richardii Brongn. require storage for several months before attaining maximum germination rate. Treatments using (2-chloroethyl)phosphonic acid increased germination rate in freshly collected spores and decreased germination rate in older spores.
