Abstract

Low temperatures during germination and in the young seedling stage induce earlier flowering in spinach and chervil (Anthriscus cerefolium). Seed vernalization reduced yields considerably in both crops, especially at later sowings. After germination at a higher temperature (20 degrees C) for four days, yields were considerably higher in both crops, this effect being strongest at early sowings for spinach and at 3ate sowings for chervil.
