Germination behavior of sand-coated sweet pepper seed

Germination behavior of sand-coated sweet pepper seed

1982

A:PS

Germination rate of sand-coated pepper (Capsicum annuum L.) seed (sand grain size < 75 micro m for an inner coat and 75-105 micro m for an outer coat layer) was faster than clay-coated seed but was slower than raw seed. Part of the germination reduction in sand-coated seeds was caused by the water-soluble Gelvatol binder used. High oxygen (O2) levels promoted the germination of sand-coated seed to a rate comparable to that of raw seed. This suggests that even with a porous sand-coating material, O2 may be limiting for the germinating seed. When inorganic O2-releasing compounds (BaO2 or NaBO3) were incorporated into the sand material, the germination of pepper seed was further inhibited. [AS]
