Abstract:

The present study was carried out to explore the response of seed germination of Galinsoga parviflora and Oenothera rosea to temperature and humidity. Germination percentage, germination potential and germination index was examined in 6 different temperature and 5 kinds of humidity. It was showed that the optimum germination temperature of G. parviflora and O. rosea was 25℃ and 28℃ respectively. Optimum germination humidity of both weeds was 40%. The non-optimum temperature and humidity influence germination potential and index, which delay seed germination.
