Germination response of Eleusine Indica (L.) Gaertn, seed to different light quallities and intensities

Abstract

A study was conducted on the germination response of Eleusine indica (L.) Gaertn. seed to different light qualities and intensities in the laboratory. The seeds were from three different biotypes namely glyphosate-resistant and glyphosate-susceptible biotypes from Bidor and glyphosate-resistant biotype from Chaah. The seeds were germinated in Petri dishes involving seeds with and without seed coat. The results indicate that the seeds without seed coat recorded higher germination rate. Based on the result of the study, it can be concluded that Eleusine indica seed was found to be light insensitive. Therefore. light quality and light intensity does not play a vital role in controlling the weed dormancy. However. the seeds were found to germinate in darkness. The seed with seed coat which plays an important role in preventing water, gases penetration into the seed poses the greatest barrier to the seed itself.
