evaluating inhibitory potential of rice cultivars (oryza sativa l.) root exudates on characteristics of barnyardgrass (echinochloa crus-galli) weed
this experiment was conducted to screening phenolic acids in root exudates of three rice cultivars (neda, taichung and sepidrood) by high performance liquid chromatography (hplc) method and to evaluate allelopathic potential of these cultivars on growth characteristics of barnyardgrass weed. the experiment was arranged in factorial based on completely randomized design with four replications in...
متن کاملevaluation of herbicide application and seeding rate on competition between rice (oriza sativa l.) and barnyard-grass (echinochloa crus-galli(
in this experiment which was conducted at a field of ramin agriculture and natural resources university (khouzestan, iran) in 2005, the effect of molinate at 0 (weedy check), 2.16, 3.6 and 5 kg/ha and seeding rate of 100, 120 and 140 kg/ha was evaluated on the competition between rice and barnyard grass (echinochloa crus-galli) in a split plot design with four replication. the interaction effec...
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 ...
متن کاملThe 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...
