The effect of nutrition on conidiation and conidial germination of Fusarium anthophilum obtained from barnyard grass (Echinochloa crus-galli)
An isolated Fusarium anthophilum (A. Braun) Wollenweber (isolate 16C) has been considered as a candidate for microbial control of barnyard grass [Echinochloa crus-galli (L.) P. Beauv]. The effects of nutrition on conidiation, germination rate and germ-tube elongation of conidia of the fungus were evaluated. Conidia yield, conidial germination and conidial germ-tube elongation of the fungus grow...
متن کاملAnaerobic Metabolism in Germinating Seeds of Echinochloa crus-galli (Barnyard Grass) : METABOLITE AND ENZYME STUDIES.
Echinochloa crus-galli, a problem weed in rice fields, has the rare ability to germinate and to grow in a totally oxygen-free environment. After 7 days growth in the light or dark under N(2), E. crus-galli var. oryzicola produces a 2- to 3-centimeter nonpigmented shoot.Ethanol, malate, and lactate were measured in seeds germinated under N(2) and air, and compared with changes in the activities ...
متن کاملGermination of Echinochloa crus-galli (Barnyard Grass) Seeds under Anaerobic Conditions : Respiration and Response to Metabolic Inhibitors.
Echinochloa crus-galli L. Beauv., a rice-field weed, can germinate and grow for extended periods of time in an anaerobic environment. Compared to pea, which does not germinate under anaerobiosis, the evolution of CO(2) in Echinochloa and rice is lower and the peak rate of CO(2) evolution is delayed when germinated without oxygen. The plants studied also differ with respect to their respiration ...
