Bioherbicidal potential of essential oil from leaves of Eucalyptus tereticornis against Echinochloa crus - galli L
The present study was undertaken to explore the bioherbicidal potential of essential oil(EO)(25 to 250μg/ml) from Eucalyptus tereticornis against one of the major weed of rice (Oryza sativa L.), i.e. Echinochloa crus – galli L. considering percent germination, root length and shoot length development chlorophyll, protein and carbohydrate content and percent cellular respiration). Studies reveal...
متن کاملInhibitory Effects of a Variety of Aldehydes on Amaranthus tricolor L. and Echinochloa crus-galli (L.) Beauv.
Thirty-seven commercial aldehydes containing aliphatic chains and aromatic rings as well as heteroaromatic rings were evaluated for their inhibitory activities against Chinese amaranth (Amaranthus tricolor L.) and barnyardgrass (Echinochloa crus-galli (L.) Beauv). Polysorbate 80 (Tween® 80) was used as a surfactant and the research was preliminarily conducted at 400 μM of all aldehydes. Among t...
متن کاملCharacterization of aryl acylamidase activity from propanil-resistant barnyardgrass (Echinochloa crus-galli [L.] Beauv.)
The enzyme, aryl acylamidase, was characterized in propanil-susceptible and propanil-resistant barnyardgrass with respect to kinetic parameters, the effects of inhibitors, and the levels of activity in darkand light-grown tissues. The enzyme reaction in the resistant tissue preparation proceeded linearly with time over a 5 h time course, while activity in the susceptible tissue preparation was ...
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 ...
