摘要: Effects of temperature, concentrations of plant growth regulators on germination of yellow nut-sedge seeds was studied under controlled environmental conditions. Yellow nut-sedge seeds were placed in Petri dishes with filtration papers and the germination and radical development followed during eleven days periods. Germination development of radical length was significantly influenced by both light and temperature. Germination was highest at 35 degrees C and poor germination was observed at other temperatures (27 and 45 degrees C). The plant growth regulators enhanced the seeds germination and radical length to different degree. The results were consistent with yellow nut-sedge seeds being recalcitrant species, needing a certain environment condition to germinate.
